The state of mainline hardware decoding

$ v4l2-ctl --list-ctrls --device /dev/video0
        mpeg_2_slice_parameters 0x009909fa (unknown): type=103 flags=has-payload
   mpeg_2_quantization_matrices 0x009909fb (unknown): type=104 flags=has-payload
           vp8_frame_parameters 0x00a409c8 (unknown): type=240 flags=has-payload

This seems to indicate at least mpeg2 and vp8 are exposed. Not sure where H.264 is, maybe it needs something in rkvdec?

I've since learned from ezequielg that there is a patch to make gstreamer work with the new stable VP8 API, which I am currently attempting to build using gst-build. I'll report back with results.

All in all I'm feeling slightly better about the current status than I did 2 hours ago.
