The PCR is passed through on the incoming PID value.
The PCR is embedded on the video PID regardless of origin.
The PCR is sent on a separate PID regardless of origin.
Default PCR PID is 8180. It will only get this default value if that PID value is not
already in use in the transport stream.
9.3.5 VIDEO PARAMETER CONFIGURATION
The following parameters are available for video configuration:
Selects compression standard to use. Available options are: H.264
(MPEG-4 part 10) or MPEG-2 video codec.
Selects the encoder profile to be used. The profile determines the range of
tools from the codec “toolkit” that the encoder is allowed to utilize when
encoding. The level is set automatically depending on the current
configuration.
MPEG-2: Simple, Main and High.
H264: Constrained Baseline, Main and High.
H.264: PFAF or Filed
MPEG2: MBAFF or Field
Sets output bit-rate in CBR mode.
Video CBR (Constant Bit Rate) or CVBR (Capped Variable Bit Rate).
Sets the bounds of the output bit-rate when the transcoder operates in
CVBR.
When in CVBR mode, this sets the target Quantization Parameter of
the encoder. High QP will result in more compression at the expense
of quality. Low QP will result in higher bit-rate and better quality.
