This tag usually means that the bug is known to be in upstream mpv.

Transcripts appended. Does ffmpeg's v4l2 support work better? mpv -v av://v4l2:/dev/video0 I should point out that all the code for tv:// has been removed in upstream mpv, so if this is a bug in mpv, it is unlikely to be fixed (upstream now tells you to use the av:// form above). I don't know what "imager" and "dalton" mean. Do they have identical versions of mpv and identical kernels (probably the 2 most important bits here)? Please recreate the transcripts with the -v option to get more verbosity. Testing with newer kernels and mpv versions would be helpful, but this might be a bit harder. > Note the differences from the same procedure on two almost idential > systems.

Does your webcam actually play in mpv? Is it just the log messages that bother you? Thanks, James
