Salix Forums

Hi,

runnung Salix 14.1 32bit on a mini-ITX-PC with an AMD APU, with 1,6 MHz dual core CPU and a Radeon HD 6310 GPU, I installed the proprietary Radeon diver fglrx, which gives a much better 3D performance than the free radeon driver. However, the GPU hardware acceleration for hd videos is very poor. When playing a hd clip I made with my GoPro action cam, the CPU load is at 100% and the video is stuttering, so it's almost not watchable.

Here are some outputs:

Has anybody any idea how to make hardware acceleration for hd video work on this machine?

try another player (ex.smplayer) or version of vlc
if output of

Code: Select all

glxinfo |grep direct

is Yes

Good morning.

Do you read this wiki https://wiki.videolan.org/VLC_GPU_Decoding/

I think you need install libva and check info from vainfo.

I tested smplayer and the performance was quite as poor as with VLC, the CPU load neary 100%, but the video is not stuttering so much.
One line of the output says:

I also installed libvdpau and vdpauinfo, but:

Code: Select all

$ vdpauinfo 
display: :0.0   screen: 0
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1

I found an option in the settings of VLC, that makes the video watchable:
Tools -> Preferences -> Input/Codecs -> Codecs: Skip H.264 in-loop deblocking filter
The default value was "none" and I set it to "all".
Now the CPU load is also nearly 100% but the video is not stuttering anymore and the output of VLC is:

Code: Select all

$ LANG=C vlc Videos/Hero/GOPR0002.MP4 
VLC media player 2.1.2 Rincewind (revision 2.1.2-0-ga4c4876)

and the lines

Code: Select all

[0x8639b88] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

don't appear anymore.

However, imho that seems not to be a proper solution, because it looks like the hardware acceleration is still not working.

In the codec settings of VLC, the option "Hardware-accelerated decoding" is empty and not changable. On another machine with a nVidia chipset, this option is also empty, but the hardware acceleration works fine and the CPU load is much lower than on this machine.

[EDIT:] By the way, the output of

Code: Select all

$ glxinfo -t

Did you tried install xvba-video?

Find info for fglrx driver from alienbob blog http://alien.slackbook.org/blog/decodin ... eo-in-vlc/
and here http://www.linuxquestions.org/questions ... 175446671/

first slackbuild in google https://github.com/w41l/wlsbuild/tree/master/xvba-video

source here http://cgit.freedesktop.org/vaapi/xvba-driver/

p.s. Sorry i don`t have amd video card now for tests.
p.p.s. Last hope, update vlc.

Hi coroner,

first off, thank you very much!

First I installed the vdpau-video package and tried to build the xvba-video package from the old slackbuild, but it failed:

Code: Select all

checking for GL/gl.h... yes
checking for GL/glext.h... yes

checking for XvBA... no
configure: error: you need XvBA to build this package

A package named XvBA (or similar) I could not find. To me it looks like the xvba-video package isn't beeing maintained anymore.

Yesterday I started rebuilding VLC and because I'm a "lazy slacker"

, I used sbopkg for that, which startet also to rebuild a lot of dependency packages and I had to build some of them on a slackware machine because I could not build them in Salix.
Now, I think, there was no need for rebuilding most of these packages, but I wanted to get surs not to miss some dependencies.

However, now the new VLC is installed and the hardware acceleration works!
It took some hours to rebuild all the packages on this slow machine but it was worth it.

So, thank you very much for your support and and the infos I needed to get it done.

PS. I wanted to mark this thread "solved" but the length of the title is limited and I had to shorten it.

You should read salix official wiki especially about slkbuild and depfinder. It is more easiest way update some programs from salix repository.

p.s. I think you should try slpkg for SBo repository.
