Get or set the FPS (Frame Per Second) number (Frame Rate) configuration
This URL takes effect if only if the VIDEO_FPS is MODE1.
In multiple encoder platforms, like PlatformA, the FPS number set by this URL will set to the current encoder's FPS number.
For example, in PlatformA encoders, the MJPEG FPS number was set by this URL if the runtime encoder is MJPEG. When read, the runtime FPS number will be returned.
The supported constant FPS number depends on the sensor and encoder (platform) capabilities. Here is the summary of the FPS number with sensors and encoders. Note that supported constant FPS number listed blow doesn't mean you could set them successfully. You need to check the return code to see if the FPS number was set successfully.

- Mutliple Channel Video Encoder
The available FPS numbers depend on the type of the channel modules in the multiple channel video server. For example, the PlatformA FPS number is used if the channel modules are PlatformA encoders (Video Encoders).
- PlatformT
The available FPS numbers depend on the sensor board configurations, encoder type and streaming mode. To manage frame rate easily, we provides the maximum frame rate configuration table associated with the video resolution, encoder type and streaming mode here. This frame rate configuration table is very huge if we consider all configurations in video bitrate in MPEG4, H.264 and compression ratio in MJPEG. This table is based on 3.5Mbps in H.264 and MPEG4 and MJPEG with high quality (the total output bitrate is about 18Mbps) which are suitable for most of applications.

X: means the encoder types could be one of H.264, MPEG4 or MJPEG. Note that the H.264 and MPEG4 are exclusive.
*: FPS=8 is the new added configuration. In WEB UI design, the FPS=7 will be replaced with FPS=8. But, for URL, the FPS=7 and FPS=8 both are available.
Important Note :
- In dual streams mode, the frame rate in stream 1 has to be higher or equal to it in stream 2. Otherwise, the frame rate in stream 1 is limited to the stream 2 frame rate.
For example, the frame rate settings in stream 1 and stream 2 is 30 and 25. The actual frame rate in stream 1 is 25.- With four low cost TCM models, TCM-5111, TCM-1111, TCM-3111 and TCM-4511, the streaming throughput is limited by the hardware design. The max. frame rate at video resolution higher then VGA is lower then the frame rate listed in above table.
- PlatformK
Please Refer to PlatformK FPS number listIf the CHANNEL=n was not set with this URL to the Multiple Channel Encoders, this command is read-only command and the CHANNEL 1 video server's VIDEO_FPS_NUM configuration will be returned. If the CHANNEL 1 video server does not connect to the router, the error message will be returned.
FPS Number. Refer to the table above
VIDEO_FPS_NUMBER='30'
OK: VIDEO_FPS_NUMBER='30'
or
ERROR: VIDEO_FPS_NUMBER='30'
The FPS=8 in D1 camera and video server and some mega-pixed camera was new added configuration. Refer to the above video frame table. The availability of this setting in the firmware is listed below.
