10 years ago Just a minor contributor, so my answers are not "final/official", but: There is no support for VP8 in VDPAU, not is there any hardware accelerated decoding support for VP8 in FFmpeg. So unless these projects do a lot of work first, I'm certain that won't happen. MPEG-4 ASP is tricky because there are so many broken encoders. I'd be surprised if the hardware can even decode them all correctly. So it seems a bit questionable (also because the files you find in the wild should be SD and decodable in software just fine), but should be possible. Note that if you just add a "," at the end of the -vc list (as in the updated readme I suggested) it should at least automatically fall back to software decoding.

I've been testing libvdpau-sunxi with example videos from: http://linux-sunxi.org/CedarX/VideoRenderingChart
All videos plays nicely in MPlayer without any lags or framedroping, except these:
"big_buck_bunny_1080p_MPEG4_MP3_25fps_7600K.AVI", "park_joy_420_720p25.mp4" and "big_buck_bunny_1080p_VP8_VORBIS_25fps_7800K.WebM"*
*Cedar is capable of VP8 decoding: https://bitbucket.org/paullo612/cedarx-vp8-test VP8 video format: 0x30385056.
Do you plan to include support for these video formats?
