Unable to reproduce this at least with my cheap MJPEG-only webcams, or by making ffmpeg write H.264 to a V4L2 loopback device (with -vf realtime
).
I can still reproduce this.
Looks like it's --demuxer-lavf-probe-info=nostreams
that's doing it.
Important Information
Provide following Information:
mpv 0.32.0-577-gb961efb0af
Reproduction steps
Play back webcam input with something like this:
Expected behavior
Silky smooth playback as without
--profile=low-latency
Actual behavior
A lot of output frame drops. Pausing the player and resuming will play the video back smoothly, but kind of defeats the purpose of the low-latency profile. Applying the options of the profile one by one is unreliable to narrow down which one does it because with a few of them I've found that they only do it about half of the times I've tried.
Log file
Sample files
An ffmpeg stream copy of the webcam's H.264 input muxed into MKV does not exhibit this problem.
