As of ffmpeg-0.5, there is an option to use Nvidia VPDAU optimization, but in the current ebuild there is no way to enable this option. Reproducible: Always Expected Results: add 'vdpau' to USE flag; emerge media-video/ffmpeg configures with option --enable-vdpau. Proposed change to the ebuild file should look something like this: --- ffmpeg-0.5-r1.ebuild 2009-03-12 00:37:08.000000000 +0100 +++ ffmpeg-0.5-r2.ebuild 2009-03-14 14:55:02.000000000 +0100 @@ -39,7 +39,8 @@ schroedinger?

They actually dropped it almost immediately after or before the release (can't remember which) in the man svn trunk just because it didn't make any sense to have it in there. If anything, we should probably force it on. My 2c.
