Yes, thank you, the compilation succeeds and -vc ffmpeg12vdpau, 
ffh264vdpau and ffodivxvdpau work fine again (MPlayer at r36417 and 
FFmpeg at b37ff488b8aab2fe1245f1ba3130b1d881559794 with the 
aforementioned patches). With ffodivxvdpau though, I get quite 
frequently (but not every frame) a line like

[mpeg4 @ 0x7f1f55f31d00]marker does not match f_code

from libavcodec/mpeg4videodec.c:376 printed in the console when playing 
most of my few DivX and Xvid encoded videos, which doesn't happen with 
MPlayer from 2013-08-06 12:00 and -vo ffodivxvdpau and also doesn't 
happen with the current patched MPlayer/FFmpeg and the software decoder. 
I can suppress this only with -msglevel decvideo=0.

Thanks,
