Rate control mode
Used for H.264 and MPEG4 codecs. It specifies the
bitrate encoding for the signal. Select one of the
following:
-
Low Delay
Means Constant Bitrate Encoding (CBR) will be used.
CBR is useful for streaming multimedia content on
limited capacity channels since it is the maximum bit
rate that matters, not the average. Therefore, CBR
would be used to take advantage of all of the
channel capacity.
-
Storage
Means Variable Bitrate Encoding (VBR) will be used.
This produces a better quality-to-space ratio
compared to a CBR file of the same data. VBR files
vary the amount of output data per time segment
and the FPS value may be lower.
Stream port The number of the port being used to stream the
broadcast. This value would be used along with the URL
to access the broadcast. In the case where there are two
streams because Independent streaming is being used,
this value remains the same for both of the URLs being
used.
In case of RTSP streaming this value is not considered.
