Has anyone else encountered this issue: [mov,mp4,m4a,3gp,3g2,mj2 @ 00000239bd41b840] moov atom not found

It occurs at the end of the of video acquisition, and appears to be related to the video writer not being released. I got it for 1/6 cameras on my rig.

Where in the code does this happen? When calling ffmpeg to try to mux the video? I think this happens when the file from VPF is somehow incomplete.

Can you reproduce this reliably?

What does the queue build up look like from this recoring? One possible culprit is the writer timeout on end_processes, maybe your buffer fills up far enough that it needs more than 5 mins to empty?

did this repro ever?

timsainb commented 5 months ago

IIRC it resolves with different parameterizations but I never figured out what caused the issue
