Adding support for encoding VP8 Alpha

Multimedia / FFmpeg - Vignesh Venkatasubramanian [google.com] - 17 May 2013 08:11 UTC

This patch adds support for encoding VP8 files with alpha. The alpha channel is encoded separately and the output is placed in AVPacket's side_data. The muxer then muxes it into the BlockAdditional element of the matroska container. More details on spec here: http://goo.gl/wCP1y
