Playback freeze when switch speed or change subtitle.

[peerless2012]

I am dev o a new platform, and when I change speed from 1.0 to 2.0 or 3.0, it always works. but when I change the speed back to 1.0. it always freeze, and the video always freeze. next time I call mpv function, then it will block and produce an anr.

Change subtitles some times has the same issue.

This happends on some files and happend always, and some file not have this issue.

Here are some log when the video freeze:

onPropertyDouble name = speed , value = 1
cplayer, level = 30, text = 
cplayer, level = 30, text = Audio/Video desynchronisation detected! Possible reasons include too slow
cplayer, level = 30, text = hardware, temporary CPU spikes, broken drivers, and broken files. Audio
cplayer, level = 30, text = position will not match to the video (see A-V status field).
cplayer, level = 30, text = Consider trying `--profile=fast` and/or `--hwdec=auto` as they may help.
cplayer, level = 30, text = 

That's very wired, when I test the same video without audio, the issue gone.

And if I test test the video with audio, but is sw decode, the issue is gone.

Seems this issue always on hw decode + audio, but only on some files, not all files.

@kasper93 @Andarwinux Hi, do you have any idea about this?

I test hw decode + surface direct out, it works.

Sw decode + vo(or next) works.

Only when hw decode + vo(or next), it happend.

And when it happends, it always happend when switch speed from high to low. like 3.0 to 2.0 or 2.0 to 1.5
