I too get this kind of effect but I'm not clever enough to sort it out. An example from running mpv over a chess game for a few seconds. : $ mpv nakamura-kramnik.mkv Playing: nakamura-kramnik.mkv (+) Video --vid=1 (*) (vp9) (+) Audio --aid=1 (*) (aac) libEGL warning: DRI2: failed to authenticate AO: [sdl] 44100Hz stereo 2ch s32 VO: [opengl] 1280x720 yuv420p AV: 00:00:00 / 00:31:42 (0%) A-V: 0.000 Dropped: 3 Audio/Video desynchronisation detected! Possible reasons include too slow hardware, temporary CPU spikes, broken drivers, and broken files. Audio position will not match to the video (see A-V status field). AV: 00:00:02 / 00:31:42 (0%) A-V: 0.000 Dropped: 62 Exiting... (Quit) pthread_mutex_destroy on mutex with waiters! The paragraph beginning Audio/Video is highlighted in a yellow colour. (Colorls is installed and I use reverse video.) Playing for longer gets the same desynch error repeated often. Thanks Moss
