| <p>This misc parameter buffer defines the maximum size of a frame (in bytes) settings for multiple pass. currently only AVC encoder can support this settings in multiple pass case. If the frame size exceeds this size, the encoder will do more pak passes to adjust the QP value to control the frame size. </p> |
