VIDEO_MAX_BITRATE

Description

Get or set the maximum video bitrate in bits/sec for MPEG4/H.264 encoding. This might be very useful in the networking bandwidth limited environment.

This URL will not take effect if

  1. The encoder type is MJPEG (refer to VIDEO_ENCODER)
  2. The Video Quality is not NONE in MPEG4/H.264 encoding (refer to VIDEO_MPEG4_QUALITY, VIDEO_H264_QUALITY).

Note when the maximum video bitrate was not set to UNLIMITED, the encoding engine will limited the amount of encoded data per second  which might cause poor video quality) to meet the bitrate requirement.

If the maximum video bitrate is UNLIMITED, the encoding engine will encoded the video image based on the average bitrate setting.

If the CHANNEL=n was not set with this URL to the Multi-Channel device, this command is read-only command and the CHANNEL 1 video server's VIDEO_MAX_BITRATE configuration will be returned. If the CHANNEL 1 video server does not connect to the router, the error message will be returned.

Input Argument

28K, 56K, 128K, 256K, 384K, 500K, 750K, 1M, 1.2M, 1.5M, 2M, 2.5M, 3M, 3.5M, 4M, 4.5M, 5M, 5.5M, 6M in unit of bits/sec.

Note that bit rate from 3.5M to 6M are available in PaltformT encoders only.
