Vittorio Giovara	bddd8cbf68	Add transformation matrix API. ... Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>	2014-05-19 13:13:10 +02:00
