sony slt dual mode wait-event

--wait-event-and-download in a dual raw+jpg setting does not work, it leaves one image on camera,
which after some tries fills the memory.

use some logic like in sony_capture

Nikon D810 setting the "recordingmedia" config value

Hello,

we've been using libgphoto2 over the last 2 years with great success, however we have recently wanted to change the "recordingmedia" config value on our Nikon D810's and have been unable to do so. This works fine on our Nikon D800E's, which leads us believe that this problem is specific to the D810's.

Heres how we went about trying to set the config value with libgphoto2 2.5.9.

First identify the camera port and config value.

OpenMVS-Shell:/local/bzffacel/tmp$ gphoto2 --auto-detect
Modell                         Port                                            
----------------------------------------------------------
Nikon DSC D810                 usb:002,035     
Nikon DSC D800E                usb:003,103     

OpenMVS-Shell:/local/bzffacel/tmp$ gphoto2 --port usb:002,035 --get-config=recordingmedia
Label: Aufnahmemedium                                                          
Type: RADIO
Current: Speicherkarte
Choice: 0 Speicherkarte
Choice: 1 Kamera SDRAM
Choice: 2 Unbekannter Wert 0002

Then try and set the config and see if it has changed.

OpenMVS-Shell:/local/bzffacel/tmp$ gphoto2 --port usb:002,035 --set-config-value=recordingmedia=Kamera\ SDRAM
OpenMVS-Shell:/local/bzffacel/tmp$ gphoto2 --port usb:002,035 --get-config=recordingmedia
Label: Aufnahmemedium                                                          
Type: RADIO
Current: Speicherkarte
Choice: 0 Speicherkarte
Choice: 1 Kamera SDRAM
Choice: 2 Unbekannter Wert 0002

This same procedure works as expected with the D800E and changing other config values on the D810's hasn't been a problem thus far.

Alternative to gp_camera_get_config to read only specific ptp properties

Hi,

I work on an opensource project to allow remote control of dslr cameras through ptp.
I decided to use gphoto because I hate reinventing the wheel and gphoto2 seems to be perfect for my needs.

I would like to be able to read in real time some ptp properties like aperture, bargraph, iso etc, while showing the liveview frames (real time also).
My problem is that the only method I've found that allow to read the properties is gp_camera_get_config, and it reads all properties.

So if I call this method every 500ms (for example), I miss a lot of liveview frames.

The goal of my project is to use the remote liveview of the camera on an external screen inside an underwater housing, and so we don't want to miss liveview frames because it might be uncomfortable for film (and photography).

I already seen in the code base of libgphoto which kind of method I would have to add, but before doing this I would like to know if this feature already exists ? Or what would be the best way to implement it ?

Thank you.

Regards,

Romain.

capture-image-and-download doesn't work 2nd time

Hi Marcus et al,

Unfortunately I am experiencing this issue with the latest gphoto2 v2.5.10. I am using a Canon EOS 1200D usb-connected to a Raspberry Pi. The camera is set in video mode, as capture-image-and-download wouldn't work even the first time with P, A or M modes.

Here is what happens:
pi@raspberrypi ~ $ gphoto2 --capture-image-and-download
ERROR: Could not capture image.
ERROR: Could not capture.

*pi@raspberrypi ~ $ gphoto2 --capture-preview
Error (-110: 'I/O in progress')

*For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your problem.
If you intend to send any error or debug messages to the gphoto
developer mailing list [email protected], please run
gphoto2 as follows:

env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --capture-preview*

Please make sure there is sufficient quoting around the arguments.*

If I add the --debug flag it works, but not if I set a debug-logfile!

I've attached the logfile and camera configuration.

(Btw, I removed those tethering files:
/usr/share/dbus-1/services/org.gtk.Private.GPhoto2VolumeMonitor.service
/usr/share/gvfs/mounts/gphoto2.mount
/usr/share/gvfs/remote-volume-monitors/gphoto2.monitor
/usr/lib/gvfs/gvfs-gphoto2-volume-monitor)

I am at a loss now as to how to resolve it, and am even considering looking for an alternative product, so any help would be much appreciated.

Regards,
Jam

event queue pruning

if we received an objectadded event and later a objectremoved event, the internal event code could remove the objectadded if it was not yet fetched by the external user of the library.

this avoids a ptp chdk issue ( https://gist.github.com/anonymous/8f0ed5effc88173c0ea0 ) where we try to getobjectinfo on a already deleted image, because our event handling is too late.

segmentation fault/corrupted double-linked list on powering down camera

When camera is manually powered down shortly (1-2sec) after it gets connected and while still processing queued events (cam.processEvents) the program intermittently crashes with segfault or "corrupted double-linked list".

Main:
while (1)
{
if ( !cam.isConnected() )
{
if ( !cam.connect() )
sleep(2);
}
if ( cam.isConnected() )
cam.processEvents(500);
}

cam.processEvents:
{
if ( !bConnected )
return;
CameraEventType evttype;
CameraFilePath _path;
void *evtdata = 0;
if (GP_OK != gp_camera_wait_for_event (_camera,timeout_ms, &evttype, &evtdata, context))
{
disconnect();
return;
}
switch (evttype)
{
case GP_EVENT_FILE_ADDED: // did not ask for file, discard it
path = (CameraFilePath)evtdata;
gp_camera_file_delete(_camera, path->folder, path->name, _context);
break;
default:
break;
}
if ( evtdata )
free (evtdata);
}

cam.disconnect:
{
if ( _context && _camera )
gp_camera_exit(_camera, _context) ;
if ( _camera )
gp_camera_unref(_camera);
if ( _context )
gp_context_unref(_context);
_context = NULL;
_camera = NULL;
}

gp_log_add_func can return duplicate ids

The gp_log_add_func function takes its returned id from the log_funcs_count variable. However, if gp_log_remove_func is called then log_funcs_count is decremented. This can result in two different callbacks having the same id. For example:

id_1 = gp_log_add_func(GP_LOG_VERBOSE, callback, NULL);  // id_1 == 1
id_2 = gp_log_add_func(GP_LOG_VERBOSE, callback, NULL);  // id_2 == 2
gp_log_remove_func(id_1);
id_3 = gp_log_add_func(GP_LOG_VERBOSE, callback, NULL);  // id_3 == 2
gp_log_remove_func(id_2);
gp_log_remove_func(id_3);  // returns GP_ERROR_BAD_PARAMETERS

Where is "--config" on gphoto2 & libgphoto2 2.5.9?

I build gphoto2 and libgphoto2 2.5.9, but not found "--config"? "--list-config" working fine.
What steps have I forgotten?

BTW：
{"Nikon:Coolpix 4100 (PTP mode)", 0x04b0,0x012d, PTP_CAP|0}
fix it:

Libgphoto2-2.5.10 Installation Problem

While attempting to install libgphoto2 version 2.5.10, I noticed that after make install, my library version was still 2.5.8. I have gphoto2 version 2.5.10 so the newly added features such as gp_camera_get_single_config produce a "symbol lookup error". I'm not sure why libgphoto2 is not updating/installing properly. Here's my process

sudo ./configure --prefix=/usr/local
sudo ./make
sudo ./make check
sudo ./make install

Thanks.

Failed to detect camera with GPhoto2 from Solid information

According to the bug 307839 in Digikam, the Solid component seems to fails somehow when trying to get information from camera through Digikam. The only error message output in the console is:

digikam(26035)/digikam (core): Failed to detect camera with GPhoto2 from Solid information

I could confirm this bug with both a Nikon D5500 and a Nikon Coolpix P610.

Is there any more information I could provide to help find the root cause?

Unable to compile, configure file has gone

Hi, I'm the owner of https://github.com/gonzalo/gphoto2-updater, a script to automatically compile the last version of gphoto/libgphoto over ubuntu/debian/raspian.
I'm trying to update my code to the new gphoto2 github repository but I've observed that some files have changed. Configure file has gone and "autoreconf --install --symlink" gets an "error: couldn't open directory 'm4m'".

So, do you have any suggestions to compile it over Ubuntu?

Host->Camera ptpip transfers hang on Nikon due to ptp_ptpip_sendreq() wrong phase

Hi,

I wanted to bring to your attention a bug that causes Nikon cameras to stop responding after completing a PTPIP MTP request that involves a Host->Camera transfer, for example a "--set-config datetime=now". I'm new to github and not familiar enough with the libgphoto2 codebase to make the necessary change but here's what needs to be altered:

ptp_ptpip_sendreq() needs to use a "ptpip_cmd_dataphase" parameter of 2 for Host->Camera transfers. It presently always sets the dataphase to 1, irrespective of the command's data direction. Existing code:

ptp_ptpip_sendreq (PTPParams* params, PTPContainer* req)
{
       int     ret;
       int     len = 18+req->Nparam*4;
    unsigned char   *request = malloc(len);

    ptp_ptpip_check_event (params);

    htod32a(&request[ptpip_type],PTPIP_CMD_REQUEST);
    htod32a(&request[ptpip_len],len);
    **Dhtod32a(&request[ptpip_cmd_dataphase],1);   /* FIXME: dataphase handling */**

The correct dataphase values for each data direction should be:
Camera->Host or No Data: 1
Host->Camera: 2

With the incorrect data phase, here's what the trace looks like for a SetDevicePropValue:DateTime request from gphoto:

Building libgphoto2 on Visual Studio 2015

Before someone shuts me off, I am aware of this disclaimer on the main page:

Platforms
libgphoto2 should compile and run on pretty much all Unix-like platforms.
libgphoto2 has not (yet?) been ported to any operating system from MicroSoft.

Having said that, I embarked on porting libgphoto2 for Visual Studio. It is a wonderful tool and my primary motivation was to provide access to SLR camera's using a port of libgphoto2 for Micromanager.

I have been successful to a very large extent. However, I am facing issues with something that I am not well versed with; loading dynamic libraries using ltdl !! If this problem is solved, then, I think we can indeed get a port of libgphoto2 on windows. Here are screenshots of my build and the exact problem that I am facing
Summary of my problem:

a.) I am trying to detect my Lenovo K3-Note camera (a model supported by libgphoto2 and verified on a linux machine)
b.) libusb is detecting the device
c.) ptp2.dll is being loaded by ltdl (as seen in the screenshots)
d.) The camera is not being initialized after lt_dlsym (screenshots attached).

The only dependencies that I had to build were:
a.) libusb (built as a static library using VS2015)
b.) libtools (for ltdl ; Used Msys/MinGW - gcc 5.2.1 and exported the symbols using dumpbin and created a VS2015 import library using lib)
c.) pthread (built as a static library using VS2015)

The iolibs are stored in <path_of_executable>/iolibs
The camlibs are stored in <path_of_executable>/camlibs

I have provided global paths for iolibs and camlibs as environment variables in Windows.

My fork (along with changes that I had to make) can be found
https://github.com/skn123/libgphoto2

Please comment on any aspect of the code so that I can share with the community a CMake version of libgphoto2!

copying images from a camera gives -1: 'Unspecified error', second attempt succeeds (regression from 2.5.7)

When I try to copy pictures from my camera, I get error getting file: -1: unspecified error in Nautilus for every single picture. The pictures are copied over, but it shows this error for every single one of them. Using gphoto2, it looks like this:

$ gphoto2 --debug --debug-logfile=gphoto2-debug.log --get-file 2 

*** Error ***              
PTP Invalid Object Handle
*** Error (-1: 'Unspecified error') ***       

Again, second attempt for the same image succeeds every time (even after disconnecting and reconnecting the device, that image can be copied without issues).

I have reported the issues initially against gvfs, please see the full bug report here:
https://bugzilla.gnome.org/show_bug.cgi?id=760162

There is gphoto2 debug log attached here:
https://bugzilla.gnome.org/attachment.cgi?id=318316

Copying works correctly with libgphoto2-2.5.7-4.fc23.x86_64, but is broken with libgphoto2-2.5.8-1.fc23.x86_64 (Fedora 23).

Thanks for looking into this.

Sony ptpip feature request

This isn't an issue but rather a future feature request. I'm hoping one day gphoto2 will be able to tell the Sony cameras when it is transferring files and when it is done. You don't need to do this but I wanted to at least bring to your attention what I've figured out so far.

Basically I started up a mini project and I'm hoping to get other Sony users to try it out to verify it works. Please check it out if you have a chance:
https://github.com/falk0069/sony-pm-alt

It is quite a hack job I did to the ptpip.c code. I basically inject 29 data packets in order to tell the Sony camera this info. Also the transactionIDs are all over the board, but the camera doesn't seem to care.

Lastly, You'll notice I created a 500 byte sonyrequest buffer. I only should have needed to defined it as 26 bytes but when I made it smaller I occasionally got a variety of segmentation fault issues. I couldn't figure out where the issue was but I believe it might be the same issue that alik55 reported (#15). I feel that it might be in the logging code since this is where the core dumps generally blew up. Of course I might be doing something completely brain dead with my packet injections. By making the buffer large enough I seemed to avoid any illegal memory boundary writes.

I'm hoping you might entertain this idea and you don't find it upsetting. Please let me know what you think.

Thanks!

Problem after first capture image and download canon 1200D

Hi,

I seem to have the exact same problem as http://sourceforge.net/p/gphoto/support-requests/129/
Iam using the exact same hardware Raspberry PI 2 model B..

Sometimes I get "You need to specify a folder starting with /store_xxxxxxxxx/" and but most of the time it just seem to hang for a while and then reporting

ERROR: Could not capture image.
ERROR: Could not capture

You can find the debug file here:
https://gist.github.com/petha/674dfe311c25ec20501b

Capturing with Canon EOS M3

It seems that capturing images with the Canon EOS M3 is not possible though it is listed with
gphoto2 --list-cameras:

gphoto2 --list-cameras | grep -i "canon eos m3"
"Canon EOS M3"

Neither the option --capture-image nor --caption-tethered works.

capture-eos-m3.txt
capture-tethered.txt

This is rather unfortunate since I specially bought this model based on this.
Is there any way around this limitation or is full support for this model planned in the near future?

External flash configuration on EOS 1200D

Hello !

I am using libgphoto2 on a Raspberry Pi to control my Canon EOS 1200D.
I would like to configure an external flash (420 EX II) from libgphoto2 but there is no such configuration option, although it is possible to configure it from the camera.
I have copy pasted the list of configuration available below.
Do you think it will be possible to configure the external flash ?

PTP Device Busy on second capture and download for EOS 1200D #2 + slow Jessie

Hi.
I know this error has been seen before, but what exactly is the fix for it?.
#13
Do I have to manually edit a file? sry, not an expert..... Where do I find the file?
I tried both the 2.5.8 and 2.5.9 (also 2.5.9.1) gphoto2 version. Because I thought the fix might have been implemented since then.

Moreover, I have one Raspberry Pi with an Raspbian wheezy image and one Pi with an Raspbian Jessie image. What I see is that on the Whezzy image it takes about 200ms from the time the command "gphoto2 --capture-image-and-download" is executed to the time the camera reacts. That is a fast respond. BUT on the Jessie image the same command takes about 1500ms until the camera reacts. What is going on there? Anyidea?

Thanks in advance,
Ben

Lags on v2.5.9

Hi!

Version 2.5.9 introduced lag between call to take_picture and actual effect.
This didn't happen in previous versions.

Any idea what can be done with it?
We wouldn't like to lock ourselves on 2.5.8 as the last working version...

Tested on Debian and Mac OS with Canon 550D.

Focus manipulation during live streaming video

Hi,

I can stream live image from my EOS camera with the following command :
gphoto2 --capture-movie --stdout | ffmpeg -i pipe:0 http://localhost:8080/feed1.ffm

Also I can do focus manipulation with the following command :
gphoto2 --set-config-index manualfocusdrive=6

Is it technically possible to do these both at the same time in Python or C by using gphoto2?

Thanks!

gtkam compile problem when HAVE_GP_PORT_INFO_GET_NAME not set

I've been having a compile-time failure for gtkam-master/src/gtkam-chooser.c when HAVE_GP_PORT_INFO_GET_NAME is not set.

The problem stems from the fact that GPPortInfo is type-defined to a pointer to an incomplete type (e.g. "struct _GPPortInfo; typedef struct _GPPortInfo *GPPortInfo;"), but the functions on_port_added(), gtkam_chooser_set_camera(), and gtkam_chooser_set_port_mask() are treating GPPortInfo as a concrete type, e.g.:

name = g_strdup_printf ("%s (%s)", info.name, info.path);

instead of

name = g_strdup_printf ("%s (%s)", info->name, info->path);

I'm attaching a very hacky patch that fixes this set of bugs for me (though it's possible I need to figure out how to set HAVE_GP_PORT_INFO_GET_NAME in my config). The biggest problem in this patch is getting GPPortInfo type-defined to a concrete type, where I've directly included a local file.

Live view and video recording

Hi!
I am developing an application used for tethered capture. And one of the things that I want to do is support both image and video capture. I have no issues with image capture but I do have some problems with video. The issue seems to be present in gphoto2 and third party libgphoto2 python bindings.

I am using the Canon EOS 5D Mark 2 and gphoto2/libgphoto2 version 2.5.8. If I trigger video recording via the command line with:

gphoto2 --set-config viewfinder=1 --set-config movierecordtarget=Card --wait-event=10s --set-config movierecordtarget=None --wait-event=2s

then the video gets recorded on to the memory card as I want.

But If I capture a preview image before that using:

gphoto2 --capture-preview

then the video will not get captured. Both of the times I will get an output error message saying that property moviecapturetarget was not set. But it will still work in the case I wasn't using preview before that.

One thing that I've noticed is this: When I have the camera in manual mode I have to enable movie recording in my camera menu (live view function settings -> stills + movie) if I want the movie to be recorded. But when I use the capture preview option that menu option gets reset back to stills only.

Is this a camera specific issue or something that can be solved?

Nikon CoolPix S2700 borken w/ 2.5.9

I've been wondering why my wife's CoolPix S2700 stopped working properly (one could run gphoto for instance with --list-folders, but not with --summary) with libgphoto2-2.5.9, so I snooped around a bit. It'd seem to come down to: 929df71. Namely:

452                 if (camera->pl->params.device_flags & PTP_NIKON_1) {
...

In case of said CoolPix S2700 camera, we end up with 0x240000 & 0x200000 and hence add extra 0xfxxx devicepropcodes which then in turn make the camera unhappy and the communications appear to hang (I haven't double checked, it could just be timing out on each extra reported property -> taking very long to eventually fail). I have however removed the above mentioned snipped and the resulting SW warked again with that Nikon. I am by no means well versed in matters camera related SW, so I hope this is of at least some use. Let me know if further information or tests should be of assistance.

I suppose other Nikon cameras can be affected as well. But basically grouping in that check seems a bit too broad.

I had a similar failure a couple of weeks ago, but that time was on deleting with -DR. Again, it was after the work was done, and a following "list" showed the deleting had finished.

Hard to reproduce, perhaps it is timing dependent.

videos not shown on GoPro Hero 4 Session camera

In short, no video files are shown from a GoPro Hero 4 Session. Works fine using libmtp though.

Error setting property "movie" on Nikon D5200

I'm using Nikon D5200 to capture video. It provides toggle property "movie" to start/stop capturing video. I'm able to capture video using gphoto2 command line tool to capture video. But when I'm trying to toggle this property using libgphoto2 from my code, it always returns me error code -1. I'm using libgphoto2 2.5.9 and gphoto2 2.5.9. I tried other version too but same result. I've used gphoto's set_config_value_action() as my reference code to set the camera parameters. I'm able to set all other parameters like shutterspeed, iso, aperture, whitebalance except this particular.

Calculating time incorrectly for Canon 700D

I noticed with my camera that the timestamp on files downloaded by gphoto2 or shown in gphotofs are incorrect. The time calculated seems to be the UTC time with the time zone delta applied twice. For example, if the picture was taken at 15:00 UTC and the time zone is set for New York (Eastern), both within the camera settings, the time on the file will be 05:00. I suspect some quirk(s) need to be added to the library to support this camera.

To make it a tad more interesting, the time returned by the command-line tool is off too depending upon how I access the configuration.

This is off an hour. Possibly, this is EDT. See the next example for why I suspect that.

# gphoto2 --get-config /main/settings/datetime
Label: Camera Date and Time

Can't build libgphoto2 2.5.9.1 on OSX, libltdl error

On OSX w/ homebrew and xcode.

I acquired the source as follows:

git clone https://github.com/gphoto/libgphoto2

I run autoreconf then ./configure and get the following error:

checking that we can compile and link with libltdl... no
configure: error: cannot compile and link against libltdl
libgphoto2 requires libltdl (the libtool dl* library),
but cannot compile and link against it.
Aborting.

I'm able to repeat this on two different macs. I'm able to compile fine on Ubuntu.

Every second capture-image fails on Nikon D750 in v2.5.9

I'm using libgphoto2 2.5.9 with a Nikon D750 on Mac OS 10.11.1 with homebrew binaries. If I go to the gphoto2 --shell mode, the first time I run capture-image, it works, but the second time I get an error. If I run capture-image again, it works, then the next time, an error, etc. libgphoto2 2.5.8 doesn't have this problem.

Here is me running gphoto2 on 2.5.9:

$ gphoto2 --shell --debug --debug-loglevel=all --debug-logfile=debug-2.5.9.txt
gphoto2: {/Users/insitu} /> capture-image
New file is in location /capt0000.jpg on the camera
gphoto2: {/Users/insitu} /> capture-image
ERROR: Could not capture image.
ERROR: Could not capture.

and now the same on 2.5.8:

$ gphoto2 --shell --debug --debug-loglevel=all --debug-logfile=debug-2.5.8.txt
gphoto2: {/Users/insitu} /> capture-image
New file is in location /capt0000.jpg on the camera
gphoto2: {/Users/insitu} /> capture-image
New file is in location /capt0001.jpg on the camera

I noticed these lines in the 2.5.9 debug log, not sure if they're related:

Tethering doesn't work on the Sony A77M2

I've tried using gphoto2 2.5.9 to do tethered capture with a A77M2. I'm running the ubuntu xenial packages on ubuntu trusty so it's possible there's something wonky with my install.

The camera gets detected apparently fine:

However when I try --capture-image-and-download the camera seems to try and focus and then do nothing. When I do --capture-tethered nothing seems to happen even after I press the camera shutter. I've ran the following command as suggested by the program:

env LANG=C gphoto2 --debug --debug-logfile=a77m2-logfile.txt --port usb: --capture-tethered

and here's the output: a77m2-logfile.txt

SEGV when trying to access Pentax K100D

Hello,

i wanted to try entangle which is based on gphoto2 with my Pentax K100D.

I use entangle and gphoto2 on Linux Mint Debian Edition2, which is based on Debian Jessy:

chris@lm-joe ~ $ dpkg -l | grep gphoto

The camera is detected by gphoto2:

chris@lm-joe ~ $ gphoto2 --auto-detect
Modell                         Port

But when trying to access it gphoto crashes:

chris@lm-joe ~ $ gphoto2 --config

Same, but called with strace to get some detail infos about the crash:

chris@lm-joe ~ $ strace gphoto2 --config 2> strace-out-crash.txt
Segmentation fault

I also started gphoto2 as recommended when it crashes:

chris@lm-joe ~ $ env LANG=C gphoto2 --debug --debug-logfile=gphoto-debug.txt --config
pentax/pslr.c:265:ipslr_status(p, statusbuf) failed: 4

Support for Fuji x-t10

I was just wondering if there are any plans for supporting image capturing with Fuji x-t10?
File download seems to be supported, but if image capturing could be supported it would be great.

C++ programming is a bit out of my scope, but if you need any info/testing/debug dumps from an x-t10 I'll be glad to help.

Thanks!

Sony DSC (wx1) Tethered Shooting Support (?)

hallo,

where can i get "Tethered Shooting" supporting drivers for the "Sony DSC" modells especially the wx1 ?

Thx

A7S ISO change down goes up when cam is at 25600 or higher, then gets stuck

When the camera is at ISO 25600 or higher and you try to set something lower, it will climb to 64000 then flap between 51200 and 64000. Also, 51200 specifically cannot be set, so this may be a contributor.

'gphoto2 --set-config iso=3200'

I think there is more going on here but haven't had a chance to test all of it.

Support for exFAT

I have a 64GB card that gets formatted to exFAT automatically by my camera. This gets mounted in /etc/mtab as fuseblk when automatically mounting through the GUI. I am under the impression the only exFAT driver is FUSE. It appears as though this line prevents it from getting a port name of disk:/media/path/. As expected, if I edit /etc/mtab after I mount the card, and change 'fuseblk' to just 'fusblk' - this card will get the proper port name (disk:/media/path/) . See below for the specific commands I ran and for the edits I made to /etc/mtab.

Note: I'm specifically using this for Darktable and doing this modification lets me see my card (and import from) appropriately.

OS: Ubuntu 14.04

/etc/mtab:

/dev/sdd1 /media/james/NIKON\040D3300 fuseblk rw,nosuid,nodev,allow_other,blksize=4096 0 0

➜  ~  gphoto2 --auto-detect
Model                          Port                                            
----------------------------------------------------------

Again - if I change 'fuseblk' to 'fusblk' it will avoid the if statement linked here:

/etc/mtab:

/dev/sdd1 /media/james/NIKON\040D3300 fusblk rw,nosuid,nodev,allow_other,blksize=4096 0 0

➜  ~  gphoto2 --auto-detect
Model                          Port                                            
----------------------------------------------------------
Mass Storage Camera            disk:/media/james/NIKON D3300

I would be more than willing to submit a PR removing this line (and possibly the 3 others in the similar if statements), but it appears as FUSE has been explicitly ignored via this commit although the reason is not stated. Unfortunately, the link in the commit message is dead (which might have contained relevant discussion).

I should note that I would not have been able to accomplish any of this without the help of @jfly. He sat on hangouts with me for hours while we ran down a very deep rabbit hole :)

locale and menu values

Hi,
I'm not sure if this is related to my camera (canon eos 350d).

When I try to get a widget configuration, with my LC_ALL set to it_IT, I get values translated in my language:

LC_ALL=it_IT.UTF8 gphoto2 --get-config=imageformat
Individuata una "Canon:EOS 350D (normal mode)".                                
Label: Formato immagine
Type: MENU
Current: RAW
Choice: 0 RAW
Choice: 1 RAW 2
Choice: 2 JPEG Normale piccola
Choice: 3 JPEG Fine piccola

But if I try to set it to any of the found values, it just fails:

LC_ALL=it_IT.UTF8 gphoto2 --set-config imageformat='JPEG Fine larga'
Individuata una "Canon:EOS 350D (normal mode)".                                
Impostazione del formato immagine non valida

If I set the value to the appropriate english translation, it works fine:

LC_ALL=C gphoto2 --set-config imageformat='Large Fine JPEG'
Detected a 'Canon:EOS 350D (normal mode)'.                                     
Image format changed

(Note: even if I changed LC_ALL on set-config, it seems completely irrelevant).

I actually noticed this bug not via the gphoto2 app, but trying to change settings via C++ api.
A workaround is to call setlocale(LC_ALL, "C") just before connecting my camera.

--new does not work with EOS 6D

Hi!

I try to transfer only the images taken since the last transfer, but i always get a transfer of all images.
Example Workflow:
A: Take some Pictures
B: gphoto2 --new -P => all images transferred
C: process and delete images on host
D: take more Pictures
E: gphoto2 --new -P => all (old and new) images transferred

I am running gphoto2/libgphoto2 build from git.
I can provide traces if they are useful.

Greetings,
Arne

multiple Canon 1200D's are giving randomly "Canon EOS Full-Press failed" error

Hi,

I also commented on issue #30 because i think we are having the same problem.

So the error is as following:

Canon EOS Full-Press failed (0x2019: PTP Device Busy)
ERROR: Could not capture image.
ERROR: Could not capture.

I get this error quite random, sometimes after taking 3 pictures successfully, sometimes after 1 and sometimes after 10.
We are having manny 1200D and they all give this problem.

The command i use is the following "gphoto2 --capture-image-and-download"
Also i tried all the "eosremoterelease" options, but with no results.
My application don't need auto focus, so all tests are done with manual focus.

The log file you can find here
The version i am using is 2.5.10.1

Thanks!
Ben

Please support SONY A6300
