Command Line DirectShow Image capturing device

dsgrab's Issues

Always default to 24-bit output

What century do we live in again? Right. Drop support for all other colour modes to simplify the code.

Match device by Pre/Infix

Hi,
It would be nice, if it is enough, to specify the first characters of a webcam (until it is unique) in order to select it. I had the problem today, that (on German windows 7) a Camera was called "USB-Videogerät", but the "ä" was somehow wrongly transferred, so that DsGrab did not match it to the Device name. This could be avoided if I could just say "USB-" and it matches everything with USB- prefix.

Even better would be something like "abc" which matches every device with's name contains "abc"...

Add ability to capture from multiple capture devices.

Add ability to capture from multiple devices using the new -n parameter. Something like:

 dsgrab -n 1,3,5

etc.

Error message is misspelt

When you pass in a bad extension, the error message says "The extension xxx is not support by DSGrab". It should say supported.

Implement YUV -> RGB filter

Some webcams do not implement a RGB output pin in their DirectShow driver. A filter needs to be added to the DIrectShow graph which does the conversion so that a proper RGB image can be generated.

Vista and 7 have a built in colour space conversion filter, but Windows XP does not so a custom written filter needs to be added (or lifted from the internet).

Binary file

Hi, url not working, please put binary file to release.

Use Boost for Command Line parsing

Use program_options for command line parsing

Make --device parameter case insensitive

Make it simpler for users to type their device names.

Uninitialize GdiPlus when finished.

Dispose of GdiPlus using GdiplusShutdown when complete.

More "intelligent" device selection

When limited number of options are given (i.e. no dimensions, or no capture device), the program should try its best to pick an appropriate device.

Make image output type sniffing case insensitive

There is a code block in the source code that tries to determine which CLSID to use for encoding the image based on the extension that the user gave for their output file. This comparison is case sensitive and is generally fairly poorly written (operator == instead of comparsion). Polish this up a bit.

Release AM_MEDIA_TYPE structures
