This mode apparently does not support decoding of HEVC Main (8 bit).
With D3D11 and Intel drivers on Windows 10 I get green corruption, while
using DXVA2_ModeHEVC_VLD_Main works.
Some devices (some phones, apparently) will support only this opaque
format. Of course this won't work with CLI, because copying data
directly is not supported.
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.

Some existed since forever, some are new.
The cast in get_surface() is silly, but unless we change the av_log
function signature, or all callers of ff_dxva2_get_surface_index(), it's
needed to remove the const warning.

Make supported codec profiles part of each dxva_modes entry. Every DXVA2
mode is representative for a codec with a subset of supported profiles,
so reflecting that in dxva_modes seems appropriate.
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.
Originally inspired by VLC's code.

This also adds support to avconv (which is trivial due to the new
hwaccel API being generic enough).
The new decoder setup code in dxva2.c is significantly based on work by
Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.
Merges Libav commit f9e7a2f95a.
Also adds untested VP9 support.
The check for DXVA2 COBJs is removed. Just update your MinGW to
something newer than a 5 year old release.

I want to make it non-mandatory to set a mutex in the D3D11 device
context, and replacing it with user callbacks seems like the best
solution. This is preparation for it. Also makes the code slightly more
readable.

The actual hwaccel code will need to access an internal context instead
of avctx->hwaccel_context, so add a new DXVA_CONTEXT() macro, that will
dispatch between the "old" external and the new internal context.
Also, the new API requires a new D3D11 pixfmt, so all places which check
for the pixfmt need to be adjusted. Introduce a ff_dxva2_is_d3d11()
function, which does the check.

No need to loop through the known surfaces, we'll use the requested surface
anyway.
The loop is only done for DXVA2.

The slice index expected by D3D11VA is the one from the texture not from the
array or texture/slices.
In VLC the slices we provide the decoder don't start from 0 and thus pictures
appear in bogus order. With possible crashes and corruptions when using an
invalid index.

The decoding buffer index expected by D3D11VA is the one from the
ID3D11Texture2D not the one from the ID3D11VideoDecoderOutputView array
in AVD3D11VAContext.
Otherwise, when providing decoder slices that do not start from 0,
pictures appear in bogus order. For an invalid index crashes and
image corruption can occur.

dxva2: Retry IDirectXVideoDecoder_BeginFrame()
This also adds a missig #include to prevent breaking building
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Most of the changes are just trivial are just trivial replacements of
fields from MpegEncContext with equivalent fields in H264Context.
Everything in h264* other than h264.c are those trivial changes.
The nontrivial parts are:
1) extracting a simplified version of the frame management code from
mpegvideo.c. We don't need last/next_picture anymore, since h264 uses
its own more complex system already and those were set only to appease
the mpegvideo parts.
2) some tables that need to be allocated/freed in appropriate places.
3) hwaccels -- mostly trivial replacements.
for dxva, the draw_horiz_band() call is moved from
ff_dxva2_common_end_frame() to per-codec end_frame() callbacks,
because it's now different for h264 and MpegEncContext-based
decoders.
4) svq3 -- it does not use h264 complex reference system, so I just
added some very simplistic frame management instead and dropped the
use of ff_h264_frame_start(). Because of this I also had to move some
initialization code to svq3.
