Bug ID: 91254
Summary: (regresion) video using VA-API on Intel slow and
freeze system with mesa 10.6 or 10.6.1
Product: Mesa
Version: 10.6
Hardware: x86-64 (AMD64)
URL: https://bugs.archlinux.org/task/45459
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Mesa core
Assignee: mesa-dev@lists.freedesktop.org
Reporter: toma...@o2.pl
QA Contact: i...@freedesktop.org
After upgrading to mesa 10.6.0-1 from 10.5.7 under the Intel Graphics, with the
work of the VA-API display slows down and freezes.
Additional info:
* package version(s)
mesa 10.6.0-1
mesa-libgl 10.6.0-1
* config and/or log files etc.
System: 4.0.6-1-ck x86_64 (64 bit), (tested also 4.0.5-2), Desktop: KDE (Plasma
5.3)
CPU: Dual core Intel Core i5 M 450 (-HT-MCP-) cache: 3072 KB
Graphics: Card: Intel Core Processor Integrated Graphics Controller
Display Server: X.Org 1.17.2 driver: intel Resolution: 1920x1080@60.00hz
GLX Renderer: Mesa DRI Intel Ironlake Mobile GLX Version: 2.1 Mesa 10.6.0
The problem is on Intel Core i5 M 450 - first generation (Nehalem) of Intel
Core, also tested on the i3-3220T - third generation (Ivy Bridge) and i3-4005U
fourth generation (Haswell) and it works properly.
I did not test for second-generation (Sandy Bridge).
Steps to reproduce:
Metod 1
- install mesa 10.6.0-1 and mesa-libgl 10.6.0-1 (or 10.6.1)
- install mpv and configure it:
vo=opengl
hwdec=vaapi
- play any video,
Metod 2
- install mesa 10.6.0-1 and mesa-libgl 10.6.0-1
- install kodi
- enable VA-API (Settings > Video > Acceleration)
- play any video
Symptoms: display slows down and freezes
Tested on:
- xf86-video-intel 1:2.99.917+364+gb24e758-1 and 2.99.917-5
- AccelMethod, SNA, UXA, glamor
- Linux 4.0.6, 4.0.5-2, 4.1.1
On most video files you can see the problem, but not all.
You can test to: Jellyfish Video Bitrate Test Files http://jell.yfish.us/
It helps only downgrade to mesa and mesa-libgl to 10.5.7-1
Does not help downgrade xf86-video-intel to 2.99.917-5, therefore the suspicion
that the problem is mesa.
Upgrade libva and libva-intel-driver from 1.5.1 to 1.6.0 does not resolve this
bug.
