[FFmpeg-devel] [PATCH 0/3] nvdec: Add hwaccel for mjpeg

[Philip Langdale]

This change implements mjpeg hwaccel support for nvdec on top of the hwaccel
hooks that Mark put together. When Mark previously sent the change out for
review, it included a hack to handle remapping of YUVJ pix fmts that couldn't
be merged as-is. The problem was never resolved, which blocked merging.

However, nvdec support doesn't require any remapping of YUVJ, so there's no
need for the hack, and hopefully no blocker for merging.

I have not included the other patches from Mark's original set as they are
also not required for nvdec.

Mark Thompson (1):
  mjpegdec: Add hwaccel hooks

Philip Langdale (2):
  avcodec/mjpeg: Pass full buffer to hwaccel start_frame
  avcodec/nvdec: Implement mjpeg nvdec hwaccel
