Comment (by ordroid):

 > It would be great if you could verify this because it would indicate a
 different bug than what I thought so far. The difference in the XBMC
 source code would be that the new API uses a "hwaccel" and the
 "h264/vc1/etc. decoder while the new API was based on specific decoders
 h264_vdpau, vc1_vdpau etc.

 The bundled ffmpeg in XBMC is version 1.2 and states "VDPAU hardware
 acceleration through normal hwaccel". Not sure how I'd go about verifying
 the shared behaviour.

 of the one you compiled against, using a newer one may be ok (bugs are of
 course possible), ideally you would recompile to get valid results.

 Are there any combinations I could try to help isolate this problem?

 I'm using the Gentoo git ebuild and actually had to remove some flags to
 compile these revisions. Incidentally all those enable flags map to the
 libraries I have installed through portages USE flags. But for simplicitys
 sake I'll do --enable-shared :)
