This number is definitely required when frame threading is enabled, so
add it here rather than forcing all users to handle it themselves.

DXVA2 contained this addition in specific code as well (therefore being
added twice in the internal case) - just remove it from there.

This adds a new API, which allows the API user to query the required
AVHWFramesContext parameters. This also reduces code duplication across
the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses
the new API function. It takes care of initializing the hw_frames_ctx
if needed, and does additional error handling and API usage checking.

Support for VDA and Cuvid missing.

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

I want to make it non-mandatory to set a mutex in the D3D11 device

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.

The slice index expected by D3D11VA is the one from the texture not from the

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.

Otherwise, when providing decoder slices that do not start from 0,
