Re: [vlc,mpv]:Video lags

ffmpeg/video: hevc: No support for codec hevc profile 2.

Does mplayer decode the video in HW? How's the CPU load in either case?

- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.

Re: [vlc,mpv]:Video lags

Also mplayer does not works now

You're trying to play a hevc video, which does not benefit from your IGPs hardware decoder.
(This is not a software issue, the GPU doesn't support that codec)

Did you maybe previously just test a different (h264) video?
Sanity check:

Re: [vlc,mpv]:Video lags

But I use vlc in windows, works fine on same video

So previously it worked before an update and also in mplayer and now it worked before the update but not in mplayer but in windows - make up your mind…
The relevant question is whether windows decodes the video in HW (don't guess, check what vlc says and also the CPU load)
You've also not elaborated on the CPU load (maybe the sw decoding isn't the problem, but pulsenoaudio/pipedrea…wire)

The IGP you're currently using doesn't support HEVC hw decoding. On no OS.
