DigiView for Raspberry Pi

digiview-sbc's Issues

preblem to shut down, and sd card corrupted.

Hello,

first of all, thank you for your work it's great. on the other hand I have a problem: when I turn off the Pie with the mouse, or with a command, the sd card and the image are corrupted. I have to redo the image. however I turn off the Pie well, only the red LED remains lit when I cut the power. I don't understand why, I tried everything, and I have to redo the image every time I turn off.. please help me!
thank you in advance,
AureL

dual hdmi out pi4

hi! I am using this with a pi4 and only one hdmi output is showing the feed at once, the other just shows "digiview" is there a way to have them mirrored?

Composite video out

I had enabled composite video out (via 2.5mm jack) on Raspberry Pi OS and it worked just well

After installation of DigiView-SBC image I can't enable the composite video out now.

Please tell me is it in theory possible to use raspberry as a digital to analogue converter using composite video out or there is some limitation?

feature: dvr

Has anyone considered a basic dvr function? It looks like there is a spot in the (literal) pipeline where it has effectively standard mp4 video that could be diverted to a file as well as playback.

• Connect USB storage, allow system to automatically mount it
• When goggles attached, if usb storage is present, send it to a file as well as the player: | tee /storage/dvr-2220.mp4 |
• During streaming, automatically run sync to flush the write cache periodically

Alternately:

• OUTFILE=/dev/null
  • When storage is detected, OUTFILE=/storage/dvr-2221.mp4
• Include | tee ${OUTFILE} | in the pipeline. This has a very minor performance cost for non-dvr playback, extraneously sending the stream to /dev/null
• Still run the periodic syncs during streaming, which shouldn't impact except in dvr mode. (Ideally few/no writes should be going to the system device.)

In both approaches, closing the stream will automatically close the file. The periodic sync should defend (barely) against corruption on power-off, while still allowing a reasonable write cache. Corruption risks are primarily to the DVR storage, rather than the system volume.

I might hack something together if there is any interest. Having a second screen is huge for outreach where we fly but I don't want to lose my dvr

Support OSD Using Open TX Telemetry

Feature Request

Since the DJI goggle do not support sending OSD data live while using video out, telemetry data from an Open TX could be used instead to get this information. The transmitter would either be plugged in or connected with Bluetooth.

GPIO Monitor with touchscreen not working

Hi,

I'm trying to make it working on my RPi 4B with a 4" touchscreen monitor connnected with GPIO.

I'm using your .img , I need to install monitor drivers after the first power up to see something in the display but after that I cannot see any Digiview background image on screen , only the prompt of the fpvout user.
Maybe something in the drivers broke Digiview ?

My display is a 4" and the drivers I installed are here:

git clone https://github.com/goodtft/LCD-show.git

and I used :

./MHS40-show

after that and one reboot the display started working but I got only a prompt and if I try to start even manually fpvout-start.sh it says:

fpvout@FPVOut:~ $ /home/fpvout/fpvout-start.sh
unable to open device, or device not found
try running as root (with sudo)
