// Implementation of a VideoCaptureDevice class that reads from a file. Used for
// testing the video capture pipeline when no real hardware is available. The
// supported file formats are YUV4MPEG2 (a.k.a. Y4M) and MJPEG/JPEG. YUV4MPEG2
// is a minimal container with a series of uncompressed video only frames, see
// the link http://wiki.multimedia.cx/index.php?title=YUV4MPEG2 for more
// information on the file format. Several restrictions and notes apply, see the
// implementation file.
// Example Y4M videos can be found in http://media.xiph.org/video/derf.
// Example MJPEG videos can be found in media/test/data/bear.mjpeg.
// Restrictions: Y4M videos should have .y4m file extension and MJPEG videos
// should have .mjpeg file extension.
