Anyone try using the coreavc h264 decoder which plugs into the mplayer directshow filters. Latest mplayer SVN has the patches for it.
The seems to be a fully supported linux version in the works from the corecodec team. Here's what they've said previously (3/8/07):
"but CoreAVC for Linux is a part of our Linux 'suite' of decoders that we will soon be offering. This will eventually include MP3, AAC, AC-3, ASP, AVC, MPEG-2, VC-1, WMA, WMV and more"
The coreavc decoder would allow you to decode h264 with a less horsepower.
