[FFmpeg-devel] [PATCH 1/1 v2] libutvideo: Add UT Video Decoder Wrapper
Derek Buitenhuis
derek.buitenhuis at gmail.com
Mon Oct 17 02:22:59 CEST 2011
Add a wrapper for libutvideo's decoder.
This supports decoding the following FOURCCs:
ULY0 - 4:2:0 YCbCr
ULY2 - 4:2:2 YCbCr
ULRG - RGB
ULRA - RGBA
Also, bump version.
