== Relevant Software / Hardware: ==
* AMD E2-1800 APU (/w Radeon HD 7340)
* Linux 3.12 (Distro: Arch)
* FFmpeg version 2.1
* mesa, mesa-libgl & ati-dri 9.2.3
* mplayer r36498
* mpv 0.2.3 or git (14/11/2013)
== Summary of the bug: ==
With both mplayer and mpv, some video files encoded using "MPEG-4 part 2"
render/decode incorrectly using VDPAU hardware decoding on my AMD graphics
chipset. For the record, these files render/decode fine using other
methods (e.g. XV or OpenGL), and worked fine back when I was using
Catalyst and VA-API.
I've attached mpv & mplayer logs to this ticket, and also the output from
vdpauinfo and ffprobe.
== How to reproduce: ==
* call mplayer / mpv with the appropriate arguments to enable VDPAU
decoding and rendering on an affected file
* observe noticeable garbling and and green-coloured blocking artefacts
