Hi,
Here the command that works fine at the command prompt.
C:\progra~1\GloboTRAC\ffmpeg\bin\ffmpeg.exe -i a0.m3u8 -i a1.m3u8 -i
a2.m3u8 -filter_complex
"[0]adelay=0:all=1[0a];[1]adelay=17650:all=1[1a];[2]adelay=37510:all=1[2a];[0a][1a][2a]amix=inputs=3[a]"
-map "[a]" -y all_audio.mp4
When I run the same command from the Process.Start command in C#, it just
hangs. I've even tried triggering the execution from .bat file and it
hangs as well.
If it is the subprocess, I am open to any suggestions.
Any help would be appreciated.
Marc.
It may be that FFmpeg is trying to interact with stdin, and the
subprocess is not responding like a live shell would. Try adding the
`-nostdin` option to your command line. See answer
<https://stackoverflow.com/a/47114881/1099571> to question, "ffmpeg
hangs when run in background".
If that answer helps you, consider upvoting it.
