dxva: DXVA2_ModeHEVC_VLD_Main10 does not support Main
This mode apparently does not support decoding of HEVC Main (8 bit).

version 2013-02-08 Rl
- fixes/optimization in multistrip encoding and codebook size choice,
quality/bitrate is now better than that of the binary proprietary encoder
version 2013-02-12 Rl
- separated codebook training sets, avoided the transfer of wasted bytes,
which yields both better quality and smaller files
- now using the correct colorspace (TODO: move conversion to libswscale)
version 2013-02-14 Rl "Valentine's Day" version:
- made strip division more robust
- minimized bruteforcing the number of strips,
(costs some R/D but speeds up compession a lot), the heuristic
assumption is that score as a function of the number of strips has
one wide minimum which moves slowly, of course not fully true
- simplified codebook generation,
the old code was meant for other optimizations than we actually do
- optimized the codebook generation / error estimation for MODE_MC
version 2013-04-28 Rl
- bugfixed codebook optimization logic
version 2014-01-20 Rl
- made the encoder compatible with vintage decoders
and added some yet unused code for possible future
incremental codebook updates
- fixed a small memory leak
version 2014-01-21 Rl
- believe it or not, now we get even smaller files, with better quality
(which means I missed an optimization earlier :)

hwframe: Allow hwaccel frame allocators to align surface sizes
Hardware accelerated decoding generally uses AVHWFramesContext for pool
allocation of hardware surfaces. These are setup to allocate surfaces
aligned to hardware and hwaccel API requirements. Due to the
architecture, av_hwframe_get_buffer() will return AVFrames with
the dimensions set to the aligned sizes.
This causes some decoders (like hevc) return these aligned size as
final frame size, instead of cropping them to the video's actual
dimensions. To make sure this doesn't happen, crop the frame to the
size the decoder expects when ff_get_buffer() is called.

Some devices (some phones, apparently) will support only this opaque

Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does
not support this mode, even if it's the only supported mode. But since
opaque surfaces are generally less useful, that's probably ok.

easier (DXGI_FORMAT_420_OPAQUE). It also saves memory if the staging
texture is never needed, so this is a good thing.

dxva: add declarative profile checks
Make supported codec profiles part of each dxva_modes entry. Every DXVA2

In practice, this will more strictly check MPEG2 profiles, will stop
relying on the surface format checks for selecting the correct HEVC
profile, and remove the verbose messages for mismatching H264/HEVC
profiles. Instead of the latter, it will now print the more nebulous "No
decoder device for codec found" verbose message.
This also respects AV_HWACCEL_FLAG_ALLOW_PROFILE_MISMATCH. Move the
Main10 HEVC entry before the normal one to make this work better.
