Playback log from mpv-player
I initially reported this over at the FFmpeg Trac, so just in case I
accidentally omit to mention something I've already considered (or just for
reference), that's over at <a href="https://ffmpeg.org/trac/ffmpeg/ticket/3138">https://ffmpeg.org/trac/ffmpeg/ticket/3138</a>
== Relevant Software / Hardware: ==
* AMD E2-1800 APU (/w Radeon HD 7340), i.e. PALM
* Linux 3.12 (Distro: Arch)
* FFmpeg 2.1
* mesa, mesa-libgl & ati-dri 9.2.3
* mplayer r36498, mpv 0.2.3 & VLC 2.1.1
== Summary: ==
Some files encoded into "MPEG-4 part 2" (seemingly, those using GMC, if zgreg's
hunch on #radeon is anything to go by) render/decode incorrectly using VDPAU
hardware-decoding on my AMD chipset. The files work fine using software
decoding, and worked fine back when using Catalyst & VA-API (which should mean
that the files and the hardware are fine).
By "incorrectly", I don't mean complete garbage. About half of the image
renders fine, it's just that between reference frames it progressively garbles
into a bright-green mess in heavily-updated areas. I'll try to catch a decent
screenshot demonstrating this when I can. In the meantime, I've put a sample
affected file up on my Dropbox account:

I'll re-attach here some mplayer/mpv logs, and some output from vdpauinfo and
ffprobe; and I'll also attach output from glxinfo. If there's anything extra I
ought to provide, please say so :)</pre>
