Further information: ffmpeg stops after it detects broken frames, with error messages like here: https://superuser.com/questions/1048637/ffmpeg-video-recording-freezes-after-invalid-data-found-when-processing-input
[video4linux2,v4l2 @ 0xed0c353440] Dequeued v4l2 buffer contains 32533 bytes, but 614400 were expected. Flags: 0x00012001. /dev/video0: Invalid data found when processing input Finishing stream 0:0 without any data written to it. ffmpeg behaviour is already in a 2 year old feature request which applies here as well: https://trac.ffmpeg.org/ticket/4795 This confirms that the kernel uvcvideo driver is the source of the problem - it delivers the broken frames to ffmpeg.
