From bddd8cbf68551f6405b2bf77cc3e212af9fbe834 Mon Sep 17 00:00:00 2001 From: Vittorio Giovara Date: Thu, 15 May 2014 22:06:49 -0400 Subject: 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.
