As it turns out, patch 020_mmx_intrinsics.diff which had been introduced to fix gcc being "unable to compute some register constraints in PIC mode" (quoted from Debian changelog for ffmpeg) seems to be no longer needed with GCC 4.1. Disabling that patch alone also restores H.264 playback, still allowing build with -fPIC, as long as GCC 4.1 is used; with GCC 4.0 and that patch disabled, the package fails to build. Thanks Christian Marillat for figuring this out.
Summarizing, the fix would be: 1) disable 020_mmx_intrinsics.diff 2) build with GCC 4.1 GCC 4.1 is now default in sid, and is planned to be the default in etch, therefore no change should be required for item 2, if not to allow for building in a 'pure' testing environment until current gcc-defaults migrates to testing.
