Topic: Easier MPV + SNDIO way to play .mp4 without desync found!

In order to be able to play .mp4 audio/video files...

MAJOR EDIT! THERE IS IN FACT ONE OTHER WAY besides the smplayer method!

mpv --audio-device=sndio + whatever mp4 file you wish to play!

Hope this helps some people! smile

The below still works, but its really the inferior way I think... wink


You cannot use pure mpv if you are using sndio, or the video is out of order and the sound moves faster than the video...

smplayer is required until someone figures out how to make this an easy default within regular mpv or at least feasible.

Anywho, for sndio to work with smplayer on mp4 videos:

Go to Options/preferences/General and enable the following:

Audio/Video Auto synchonization and make the audio output sndio.

I am not sure if this is an issue with other video/audio files, but if you don't do these two things, the video and audio aren't properly in sync.

Just thought I should mention this.

g4jc told me about this once, if I recall correctly.

Long story short, I feel like this should be mentioned in both the wiki and the forums as a sticky.

I was told by one of the devs moments ago that I should post here even if the other 3 don't respond back to me.

Hope this helps someone! smile

Peace!

Small side-note, don't change the A/V auto synchronization factor from 100 to any other number.  I think that might cause problems.  wink

For future versions we must go thinking about how to keep sndio in mpv, because mpv developers already removed sndio support in upstream -> https://github.com/mpv-player/mpv/commit/71d218eae4b4

Thanks for the hint! Well, there are these days ... and those decisions ... better to keep that away for the moment, just frustrating. Perhaps keeping the concurrent version as long as possible or doing that with patches coming from OpenBSD - so far people have mpv included. Either way it won't be easier besides I find the comment a little bit strange: "(Note: only supports mono, stereo, 4.0, 5.1 and 7.1 channel layouts.)"

Ahh, thank you @zapper, this is perfect! I was so confused, I was getting sound from iceweasel-uxp, but not from mpv.
