[Spice-devel] [streaming v16 00/23] Add GStreamer support for video streaming

[Francois Gouget]

This patch series adds support for using GStreamer to encode the video 
streams, adding support for VP8 and h264 codecs.

As before the patches can also be grabbed from the gst branch of the 
repositories below. Note that this time around the required support is 
already present in the client.

spice:          https://github.com/fgouget/spice
xf86-video-qxl: https://github.com/fgouget/xf86-video-qxl
spice-protocol: https://github.com/fgouget/spice-protocol


There's also 'extras' branches with more experimental/future patches for 
the curious, and gst-vNN branches to help comparing the various 
revisions.

Note that to test GStreamer support with QEMU you probably need to grab 
the patch below and set the video-codecs option to something like 
gstreamer:h264 or gstreamer:vp8.

Changes from v15:
* Added a patch to better check for sized frames.

* Added a patch to get rid of RedDrawable.sized_stream to simplify the 
  code.


Changes from v14:

* In this round the width / height removal is back because I think it 
  is relevant to the discussion around the gstreamer-encoder code for 
  copying the frames.

* I also split that change in two parts : one removing the use of the
  width / height parameters in the MJPEG encoder, and another removing 
  them from the video-encoder API.

* Added a comment and tweaked the warning in 
  is_chunk_stride_aligned().

* Added a comment in line_copy() wrt 0-byte chunks.

* Renamed max_mem to max_block_count in zero_copy().

* I also changed the patchset prefix to 'streaming' as suggested by 
  Pavel Grunt.


Changes from v13:

Rebased + some changes suggested by Christophe Fergeau.
