Unable to use dshow devices with gdigrab/ddagrab anymore #176

Closed Jaex closed 10 months ago

Jaex commented 11 months ago

Hi, I was using your dshow devices together with other devices successfully for long time but after update FFmpeg to 6.0 which is needed for ddagrab support. I cannot use dshow with gdigrab or ddagrab anymore. I thought you may have idea about what could be wrong, thanks.

Example reproduce arguments:

ffmpeg -f gdigrab -framerate 30 -offset_x 0 -offset_y 0 -video_size 1920x1080 -draw_mouse 1 -i desktop -f dshow -i audio="virtual-audio-capturer" -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -b:v 3000k -c:a aac -ac 2 -b:a 128k -y "output.mp4"

These arguments works fine with FFmpeg 5.1 or older versions but fails with FFmpeg 6.0 (latest).

FFmpeg 5.1 output:

D:\ShareX\Tools>ffmpeg-5.1.exe -f gdigrab -framerate 30 -offset_x 0 -offset_y 0 -video_size 1920x1080 -draw_mouse 1 -i desktop -f dshow -i audio="virtual-audio-capturer" -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -b:v 3000k -c:a aac -ac 2 -b:a 128k -y "output.mp4"

You can use the -report option or define the FFREPORT environment variable (to any value) to get the exact command line and the full verbose console output in a file named ffmpeg-*.log in the current directory.

I used -report option in https://trac.ffmpeg.org/ticket/10504 attachments:

Is it enough or I should also use -loglevel debug option?

Yes, video file is playable and not corrupt.

So it is working then outputting an erroneous "Conversion Failed!" message?

Yes. And because ffmpeg process exit code is not 0, my screen recording app thinks it is failed.

I tried now, it gives same result. Looks like -report is also using "-loglevel debug".

‘verbose, 40’
Same as info, except more verbose.

‘debug, 48’
Show everything, including debugging information.

So it always shows 48.

rdp commented 10 months ago

Mine doesn't say "Conversion failed" with that command? What OS? What output when run normally?
