Weird VDPAU issue

[rvdboom]

Hi,
I have a small system with an AMD Brazos CPU that has a UVD video decoding device. This type of device is supported by the Open Source radeon driver since April-May 2013 through the VDPAU library.
The kernel is a fairly recent 3.10.3, libvdpau 0.6 is installed as well as a ffmpeg compiled to support it. VLC is also compiled to support VDPAU and it's a git pull from today.
The kernel correctly says thay UVD is initialized, vdpauinfo tells that H264, MPEG4 and VC1 are available, and mplayer properly displays a h264 mkv file using about 7% CPU, which is quite good, without VDPAU, I'm closer to 35-50% CPU.
So, to sum up, UVD works well on this system.
VLC, however, fails to used VDPAU, as can be seen in the log with "-vv" parameter :

Your VDPAU driver reports a maximum supported level for H.264 of 1.6 (16), while the video is actually encoded at level 3.0 (30) according to libavcodec. This is clearly a bug in the VDPAU driver since H.264 level 1.6 does not exist to begin with.

So VLC falls back to software/CPU decoding.

The VDPAU does not support uploading video in YV12 format (or at least claims not to). Thus VDPAU cannot be used for rendering software-decoded video.

[rvdboom]

Thanks for the reply!
So mplayer would work because it does not check for these parameters? Or may because I think it uses a year old libavcodec?

[rvdboom]

Indeed, vdpauinfo reports something weird :

Code: Select all

bash-4.2$ vdpauinfo display: :0 screen: 0 API version: 1 Information string: G3DVL VDPAU Driver Shared Library version 1.0 Video surface: name width height types ------------------------------------------- 420 16384 16384 NV12 422 16384 16384 NV12 444 16384 16384 NV12 Decoder capabilities: name level macbs width height ------------------------------------------- MPEG1 16 9216 2048 1152 MPEG2_SIMPLE 16 9216 2048 1152 MPEG2_MAIN 16 9216 2048 1152 H264_BASELINE 16 9216 2048 1152 H264_MAIN 16 9216 2048 1152 H264_HIGH 16 9216 2048 1152 VC1_SIMPLE 16 9216 2048 1152 VC1_MAIN 16 9216 2048 1152 VC1_ADVANCED 16 9216 2048 1152 MPEG4_PART2_SP 16 9216 2048 1152 MPEG4_PART2_ASP 16 9216 2048 1152

which make no sense. Level 16 is also reported on my current system with no UVD device at all, just simple VDPAU that supports MPEG1 and 2 though X, I guess. It would seem as if Level 16 is some sort of default, isn't it?
I think I should post this on Phoronix to the AMD devs...

[Rémi Denis-Courmont]

Yes, it looks like the driver returns level 16 and 9216 macroblocks regardless of the codec profile.

Unfortunately, it seems there are further bugs hidden behind this one:
http://mailman.videolan.org/pipermail/v ... 93860.html

[rvdboom]

Indeed. Thanks for pointing out the discussion, I'll follow it from now on.

[rvdboom]

Some follow-up here : the supported level is indeed currently hard-coded in the VDPAU state tracked, I've openned a bug to the AMD team and they'll fix it at some point : http://bugs.freedesktop.org/show_bug.cgi?id=67530
Apparently, the only availability of NV12 as video surface is indeed a hardware limitation.

[Jean-Baptiste Kempf]

Cool to know. Thanks for the investigation.
