[31:16] VBV buffer size defined by host. The unit is in kilo
bytes (i.e., actual buffer size = VBV_BUFFER_SIZE
* 1024 bytes).
Valid only when FRAME_SKIP_ENABLE=2.
[15] 0 = Aspect ratio VUI is disabled in H.264 encoding
1 = Aspect ratio VUI is enabled in H.264 encoding
[14:4] Reserved
[3] 0 = Sequence header is not generated on the first
FRAME_START
1 = Sequence header is generated on both
SEQ_START and the first FRAME_START
[2:1] 0 = Frame skip is disabled.
The chance of the rate overshoot will be increased
when the generate bitrate is high.
1 = Frame skip is enabled using maximum buffer
size defined by level.
2 = Frame skip is enabled using
VBV_BUFFER_SIZE defined by HOST
[0] 0 = Header extension code (HEC) is disabled in the
MPEG4 encoding
1 = HEC is enabled
Bit
[31:3] Reserved
[2] 0 = Normal operation
1 = Target bitrate is changed
[1] 0 = Normal operation
1 = Target frame rate is changed
[0] 0 = Normal operation
1 = GOP size is changed
