[vlc-devel] [PATCH 00/13] Full hardware encoding support

[Steve Lhomme]

This patchset adds support for the decoder device to use when transcoding.
The same decoder device can be used by the decoder and the encoder to provide
GPU decoding to GPU encoding.

An example of (unfinished) QSV encoder is provided that supports getting D3D11
textures to encode using the D3D11 engine. It was tested with the following
command line:
--sout=#transcode{venc=qsv{gop-size=250,gop-refdist=1,num-slice=0,num-ref-frame=0,target-usage=balanced,rc-method=qp,qpi=2,qpb=5,qpp=3,async-depth=4},vcodec=h264}:file{dst=gpu.mkv,mux=avformat}

It may not compile properly on Linux (yet). The D3D11 specific code should probably
be moved in its own file.

You can find all those patches in this branch:

Steve Lhomme (13):
  transcode: create the actual encoder outside of
    transcode_encoder_new()
  sout: provide the structure size to allocate for the encoder
  transcode: create the test encoder outside of the test function
  encoder: add a function to get the decoder device to use with the
    encoder
  transcode: provide the decoder device to use with the encoder
  sout: transcode: simplify code
  sout: transcode: the fmt_input_video is always the video part of
    decoder_out
  sout: transcode: remove unused parameters
  sout: transcode: keep track of the decoder video context
  transcode: clean the decoder output format before using it as the
    encoder input
  encoder: provide a video context to match the input format
  sout: transcode: set the decoder video context in the encoder
  WIP qsv: add support for encoding from D3D11 source textures
