VIDEO_MPEG4_QUALITY

Description

> Get or Set the Video Quality in MPEG4 mode.

> This URL will not take effect if the encoder type is MJPEG (refer to VIDEO_ENCODER)

> Note when the video quality was set to NONE, the encoding engine will encoded the video image based on the average or maximum video bitrate setting. In general, the Constant Bit Rate (CBR) is used for that.

> If the video quality was set to other value (HIGH, MIDDLE or LOW), the encoding engine will encoded the video image based on the certain video quality level. In this case, the video bitrate will be very with the scene. In general, the Variable Bit Rate (VBR) is used for that.

> 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_MPEG4_QUALITY configuration will be returned. If the CHANNEL 1 video server does not connect to the router, the error message will be returned.
