Philip Langdale	ee88dcb2b0	avcodec/cuvid: Check for non 420 chroma formats - they aren't supported Despite the video parser seeming to correctly handle 422 and 444 chroma formats, the video decoder fails miserably to actually decode frames - even though no errors are ever returned; you just get frames showing unintialized garbage.

Philip Langdale	8a06669702	avcodec/cuvid: Fully re-initialize the parser after a flush. I'm not really sure how this worked at all before, but we do need to reinitalize the parser with the stream extradata.

Philip Langdale	4029f05c8b	avcodec/cuvid: Always check for internal errors during parsing The cuvid parser is basically undocumented, and although you'd think that a failed callback would result in the overall parse call returning an error, that is not true. So, we end up silently trying to keep going as if nothing is wrong, which doesn't achieve anything. Solution: check the internal error flag every time.

Philip Langdale	86910b15c9	cuvid: Implement flush to support seeking in media players Right now, if we attempt to use cuvid in a media player and then try to seek, the decoder will happily pass out whatever frames were already in flight before the seek. There is both the output queue in our code and some number of frames within the cuvid decoder that need to be accounted for. cuvid doesn't support flush, so our only choice is to do a brute-force re-creation of the decoder, which also implies re-creating the parser, but this is fine. The only subtlty is that there is sanity check code in decoder initialisation that wants to make sure the HWContextFrame hasn't already been initialised. This is a fair check to do at the beginning but not after a flush, so it has to be made conditional.

Philip Langdale	1891dfe013	cuvid: Add hwaccels and decoders for remaining supported formats cuvid/nvdecode also supports mpeg1, mpeg2, h.263/mpeg4-asp and mjpeg. It should, in theory, also support wmv3 via the vc1 support, given that vdpau supports this. However, it failed to play wmv3 samples which vdpau played correctly, so I'm not sure what to make of it.
