Fixed duration of videos

[DantrazTrev]

Currently recording to a file using timeout as a measure leads to inaccurate video lengths depending on the processing that needs to be done . Can there be any alternative here ?

Can you use ffprobe to get the duration writen to the file metadata? Also, you can try to re-encode it using ffmpeg since that most of the time solves issues with duration for me.

You can use the fix-webm-duration package to fix the duration of the webm output file.
