- Deprecated BUFFER_FLAG_SYNC_FRAME (as it actually marks key frames). - Clarified that BUFFER_FLAG_KEY_FRAME is used for encoded output buffers. - Clarified that presentationTimeUs is not an actual render timestamp (as opposed to releaseOutputBuffer's render timestamp). Bug: 12006531 Change-Id: Ia27b9f606a9d7eef9c0c2900cd864a4421c7cf31
