ffmpeg -i desktop Output file does not contain any stream [closed]
29 November 2024, by AntonioI'm trying to screen record a remote Windows VM machine which I'm accessing through ssh. I'm executing this command
ffmpeg -f gdigrab -framerate 30 -i desktop -t 00:00:10 output.mp4
which is returning the following error:

If I take a remote desktop connection and use the same command, then it works perfectly.


I've also tried running
ffmpeg.exe -f lavfi -i color=c=black:s=800x600:r=30:d=60 out.mp4
which records something but it's just a black screen.

Does anyone have any idea what could be happening? I'm clueless at this point as I haven't been able to find more info online.

How to copy video duration to the output file with ffmpeg? [closed]
5 November 2024, by user28147375I want to copy the input's duration to the output. Is there even a way in ffmpeg to achieve this?
There is nothing about this in the docs.


I'm currently using these flags:


const ffmpegProcess = cp.spawn(ffmpegPath, [
 '-i', `pipe:3`,
 '-i', `pipe:4`,
 '-map', '0:v:0',
 '-map', '1:a:0',
 '-c:v', 'copy',
 '-c:a', 'aac',
 '-crf', '27',
 '-pix_fmt', 'yuv420p',
 '-preset', 'veryfast',
 '-movflags', 'frag_keyframe+empty_moov',
 '-f', 'mp4',
 '-shortest',
 '-'
 ], {
 windowsHide: true,
 stdio: [
 'pipe', 'pipe', 'inherit', 'pipe', 'pipe'
 ],
 });



The problem:


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'pipe:3':
