4K regression on TigerLake

I have a TigerLake series i5 Intel processor and video on both the panel display as well as the external HDMI.  Sometimes the video playback hangs on 1080p even.  I'm using the realtime kernel if that matters (needed for TV tuner/Kaffeine).  Sometimes during playback using mplayer,mpv, or even the mighty vlc, it chokes to death in the middle of the video and sometimes unbottlenecks and plays catch back up where it should be.  I even tried to use a docking station capable of 5K, but it chokes on that too.  Have to install displaylink package to get it the displays on it to work.  Arandr recognizes the displays, but won't let me use them without installing the displaylink package, but even then, the video playback is not what it should be.  Maybe the lappy is lacking hardware h265 support?  Intel spec sheet says something about vp9 and some others but I don't seem to see h265.

Not using xf86-video-intel.  Is using iris mesa driver and va_gl. 
Looking at videos both 1080 and 4k version of videos report h264 in mpv.  1080p plays sometimes and othertimes lags.

Re: 4K regression on TigerLake

Using hwdec=auto and vo=gpu at least works for mpv.

Come to think of it these same videos are h264 played on raspberry pi and it chokes on the 4k one.  But can probably understand why it does it on rpi.  This thing has enough power it shouldn't choke on 4k.

Apparently these iris xe have had a rough history even with the windows drivers. 

The regression is it plays part of the video just fine while other parts of it it has intermittent difficulty.

That's not a "regression" - the vainfo looks unsuspicious.
1. what's the mpv output?
2. the videos are from a local source that actually can at the relevant bitrate?
3. check intel_gpu_top for pressure on the IGP and top for CPU/RAM pressure
4. also the session status, this looks like you're maybe running on wayland and it'd probably be a good idea to test a non-composited environment (openbox)

Awesome uses xcb so I don't think it is using wayland.

mpv without options

 (+) Video --vid=1 (*) (h264 3840x2160 30.021fps)
 (+) Audio --aid=1 --alang=eng (*) (aac 2ch 48000Hz)
AO: [pulse] 48000Hz stereo 2ch float
VO: [gpu] 3840x2160 yuv420p
Exiting... (End of file)

And of course it has the audio/video desync message.

mpv with hwdec=auto and vo=gpu

 (+) Video --vid=1 (*) (h264 3840x2160 30.021fps)
 (+) Audio --aid=1 --alang=eng (*) (aac 2ch 48000Hz)
AO: [pulse] 48000Hz stereo 2ch float
Using hardware decoding (vaapi).
VO: [gpu] 3840x2160 vaapi[nv12]
Exiting... (End of file)

intel_gpu_top showing around 40% on Render/3D and about 8% on video with hwdec and vo options with mpv.  Without mpv options, it shows 0% on video the entire time and gets up to 100% on Render/3D.

Re: 4K regression on TigerLake

mpv only uses hwdec w/ the parameter and that's also not the default, there's absolutely no surprise here: https://wiki.archlinux.org/title/Mpv#Ha … celeration
vo=gpu is default and doesn't change between the runs

This runs fine?
What are your VLC settings, do you use vaapi there?

I figure vlc is the standby. 

I haven't changed any vlc settings, but it was choking on vlc.  Now it doesn't seem to be.  Maybe adding one of the intel-media-driver or something fixed that.  intel_gpu_top shows Render/3D for vlc to be less than what mpv was using and video is a little more balanced.  Vlc says it is using Intel iHD driver.

Still makes me wonder why it was choking on the displaylink, may have to try that again.  Suspect it'll work now maybe.

Re: 4K regression on TigerLake

There's also a line on mpv that says
Using hardware decoding (vaapi) when hwdev and vo are used, but didn't pick up in redirection.  Guess I need to use tee.

And then there's an error message about pw.loop.  I'm not sure what that is.  [loop.c:69 pw_loop_new() 0x] Can't make support.system handle: No such file or directory.
