MPV playing video lag

Videos are laggy when they played via MPV.
But Videos are smooth when they played via Haruna.

what should I set in mpv?

Hi @sunriseast,

To be able to possibly provide a solution, or at least something to search for, wee need more information. IIRC, MPV is started via CLI. Something like:

mpv /path/to/video.file

Where, surprise surprise, /path/to/video.file is the path to the video file.

Please provide the output in the terminal when you do that.

Thanks for the reply.

I got as follow.```
mpv /path/to/video.file

(+) Video --vid=1 () (h264 1920x1080 23.976fps)
(+) Audio --aid=1 (
) (ac3 2ch 48000Hz)
AO: [pulse] 48000Hz stereo 2ch float
VO: [gpu] 1920x1080 yuv420p
AV: 00:00:16 / 01:46:00 (0%) A-V: 0.403 Dropped: 134

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).

Please provide the output of:

inxi --admin --verbosity=7 --filter --no-host --width

Did you try enabling Hardware video acceleration?

I tried,but video is still laggy.

Moderator edit: In the future, please use proper formatting: [HowTo] Post command output and file content as formatted text

Please format your text using Preformatted Text option so that it’s easier to read. It looks like you have an intel card.

  • Where is the file located - Network, local copy, USB etc.?
  • Try starting playback in the terminal using the following and see if it gets better. You seem to be dropping a lot of frames.

What does vainfo from package libva-utils report? In this specific case mpv is reporting that your GPU does not support h264 codecs.

On my old laptop with 4th gen intel CPU/iGPU I had to install libva-intel-driver-g45-h264 from the AUR to get hardware decoding on h264 to work.

Take a look at Hardware video acceleration - ArchWiki for the specific packages related to your card.

Kernel 5.9.16-1 was marked End Of Life in April 2021 and is no longer supported

I suggest you install LTS kernel v5.10
