NIGHT_MPEG4_QUALITY, NIGHT_H264_QUALITY

 

Description

Get or set the video quality level in MPEG4/H.264 encoders for night time mode

These URLs are the same as the VIDEO_MPEG4_QUALITY and VIDEO_H264_QUALITY in the ENCODER CGI. These URLs are only available in PlatformT encoders. When the camera enters the night time state, the night time video profile will be loaded. The encoder quality level is the one of parameters in the night time video profile. Please refer to the parameters of night time profile for further details.

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.
