00d04784d3 Move CODEC base classes into it's own library
This introduce a library which contains a set of base classes which
handles the parsing and the state tracking for the purpose of decoding
different CODECs. Currently H264, H265 and VP9 are supported. These
bases classes are used to decode with low level decoding API like DXVA,
NVDEC, VDPAU, VAAPI and V4L2 State Less decoders. The new library is
named gstreamer-codecs-1.0 / libgstcodecs.

be3de5a3db d3d11vp9dec: Add support for reverse playback
This commit moves parsing code for superframe and frame header into
handle_frame() method, and removes parse() implementation from vp9decoder
baseclass.

The combination of
- multiple frames are packed in a given input buffer (i.e., superframe)
- reverse playback
seems to be complicated and also it doesn't work as intended in some case

* Remove redundant variables for width/height and par from GstD3D11Window.
  GstVideoInfo holds all the values.
* Don't need to pass par to gst_d3d11_window_prepare().
  It will be parsed from caps again
* Remove duplicated math

4643dc1c12 d3d11decoder: Ensure the written bitstream buffer size is 128 bytes aligned
DXVA spec is saying that the size of bitstream buffer provided by hardware decoder
should be 128 bytes aligned. And also the host software decoder should
align the size of written buffer to 128 bytes. That means if the slice
(or frame in case of VP9) size is not aligned with 128 bytes,
the rest of non 128 bytes aligned memory should be zero-padded.

In addition to aligning implementation, some variables are renamed
to be more intuitive by this commit.

fe72bf6053 d3d11decoder: Register elements per GPU device with capability check
This implementation is similar to what we've done for nvcodec plugin.

single template caps cannot represent them, so this modification

Note that the legacy gpu list and list of resolution to query were
taken from chromium's code.

a39a5bf131 d3d11decoder: Refactor decoding process
* Move decoding process to handle_frame
* Remove GstVideoDecoder::parse implementation
* Clarify flush/drain/finish usage

In forward playback case, have_frame() call will be followed by
handle_frame() but reverse playback is not the case.
To ensure GstVideoCodecFrame, the decoding process should be placed inside
of handle_frame(), instead of parse().

Since we don't support alignment=nal, the parse() implementation is not worth.
In order to fix broken reverse playback, let's remove the parse()
implementation and revisit it when adding alignment=nal support.

7aad9187e4 d3d11videosink: Use ID3D11VideoProcessor interface
...for color space conversion if available

ID3D11VideoProcessor is equivalent to DXVA-HD video processor
which might use specialized blocks for video processing
instead of general GPU resource. In addition to that feature,
we need to use this API for color space conversion of DXVA2 decoder
output memory, because any d3d11 texture arrays that were
created with D3D11_BIND_DECODER cannot be used for shader resource.

This is prework for d3d11decoder zero-copy rendering and also
for conditional HDR tone-map support.
Note that some Intel platform is known to support tone-mapping
at the driver level using this API on Windows 10.

This reverts commit ddd13fc7c0

Dynamic usage can reduce the number of copy per frame but make

Also since we don't provide _map() method for the dynamic usage,
application cannot read buffers which make "last-sample" property
unusable in case of d3d11videosink.

ddd13fc7c0 d3d11: Add support for D3D11_USAGE_DYNAMIC
D3D11 dynamic texture is a special memory type, which is mainly used for
frequent CPU write access to the texture. For now, this texture type
does not support gst_memory_{map,unmap}
