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.

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.

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.
