Debug video capture device to play back y4m movies.
For video quality and performance testing.
Based on a new command line flag:
--use-file-for-fake-video-capture=blabla.y4m
(Where blabla.y4m is the full path to the file to play)
This flag _must_ be used in combination with the existing:
--use-fake-device-for-media-stream
The file format can be found described in the code and also here:
http://wiki.multimedia.cx/index.php?title=YUV4MPEG2
And many examples here:
http://media.xiph.org/video/derf/
(Only 420 would work -- 422 is _not_ supported).
With these command line flag, navigating to a web site, f.e.
http://goo.gl/qdwf6, and allowing using the camera, will
playback the video in a loop, as opposed to a fake camera or
a real camera stream.
