Ensure the smoothness of the video 4G transmission, the relevant settings of the sea-Conway vision camera

Our current RTSP video solutions are as follows:

Webcam <---------->NVR (upload via 4G) <---------->easydarwin<----------> own player (or VLC player)

If the third stream is used, there will be no skip frame phenomenon. When the gimbal rotates, the flower screen phenomenon is not serious.

The sub-stream settings are as follows:

The third stream is set as follows:

The following commands are forwarded in the NVR FFmpeg:
