[SOLVED] h264 Video Acceleration on Linux with AMD Graphics

[vecciora]

I'm using AMD E350 Radeon HD 6310 and I want to have a video player which support GPU video acceleration. I don't know how to get XvBA works with VLC. MPlayer-VAAPI performs very well but displaying wrong colors for certain videos as you yan see in the picture below.

For VLC, you need to go to Tools -> Preferences -> Input & Codecs -> Use GPU acclerated decoding.

For VAAPI, you may want to look at https://wiki.archlinux.org/index.php/VA-API or

The VLC thing doesn't help. Video playback is still choppy.

I don't think VLC can perform as good as MPlayer-VAAPI do since it does decoding in GPU at the decoding stage only (read http://wiki.videolan.org/VLC_VAAPI). VLC doesn't perform really good on Windows too when compared to K-Lite Codec Pack's Media Player Classic even when having GPU accelerated stuff enabled. I'm not sure if it's because Radeon HD 6310 doesn't have UVD (http://en.wikipedia.org/wiki/Unified_Video_Decoder)?

I think that MPlayer-VAAPI works. I don't know how it is but it's playing the video smoother and using less memory. The only problem is that wrong colors stuff.

I have installed libva1, vaapi-driver-fglrx, gstreamer-vaapi, and anything related to VAAPI but I don't really know for what.

Hello this is the result of 'vainfo' command.

Code: Select all

libva: VA-API version 0.32.0
Xlib:  extension "XFree86-DRI" missing on display ":0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib64/dri/fglrx_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA-API version: 0.32 (libva 1.0.15)
vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.8.0
vainfo: Supported profile and entrypoints
      VAProfileH264High               : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD


The second line is bothering me somehow. I mean it looks like that I need to enable that DRI thing.

Actually I'm reading this post http://forums.opensuse.org/english/get-technical-help-here/applications/453773-need-guide-using-xvba-vaapi-ati-graphic-hardware-opensuse.html currently. It looks interesting. It looks like it could make VLC plays video with GPU acceleration (read http://wiki.videolan.org/VLC_VAAPI#ATI).

I will try to enable DRI somehow and see the result.

Oh, I see where is wrong. The /etc/environment should be

Code: Select all

LIBVA_DRIVERS_PATH=/usr/lib64/dri
LIBVA_DRIVER_NAME=fglrx


and not

Code: Select all

LIBVA_DRIVERS_PATH=/usr/lib64/dri
LIBVA_DRIVERS_NAME=fglrx


I've added 'S' in 'LIBVA_DRIVER_NAME' mistakenly. Now, the 'vainfo' output.

Code: Select all

libva: VA-API version 0.32.0
libva: User requested driver 'fglrx'
libva: Trying to open /usr/lib64/dri/fglrx_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA-API version: 0.32 (libva 1.0.15)
vainfo: Driver version: Splitted-Desktop Systems XvBA backend for VA-API - 0.8.0
vainfo: Supported profile and entrypoints
      VAProfileH264High               : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD

And now VLC plays the video smoothly and eating less CPU.

Well, actually it's not solved yet. I still not sure whether VLC really have accelerated or not.

There is no hardware decoder support for 10 bit. MPlayer-VAAPI tries to decode 10 bit video as 8 bit, which results in artifacts. Just chatting at #mplayer @ freenode IRC and I got some information.

Maybe ffmpeg is too old or something. Or maybe that the MPlayer is too old or something. The MPlayer-VAAPI in Mageia is from 2011. Not the latest development snapshot of the source code. Maybe it is what causing MPlayer to display color incorrectly.

edit: sorry but currently there is no 10-bit video hardware decoding right now

I have compiled VLC from source with vaapi and avcodec enabled. Video playback is much better now because it's really working now. I'm sure because I got a message "[0x7f95ccc029d8] avcodec decoder: Using VA API version 0.32 for hardware decoding." in terminal. Another problem occurs though. The chipset really heating up and the fan moves at full speed because of this! Even after VLC is closed!
