If you set the Multicast address to 224.0.0.0~224.0.0.255, multicast may not work properly

what is Gov length?
GOV(Group of Video object planes) is a set of video frames for H.264 compression,
indicating a collection of frames from the initial I-Frame (key frame) to the next I-Frame.
GOV consists of 2 kinds of frames: I-Frame and P-Frame.
I-Frame is the basic frame for the compression, also known as Key Frame, which contains
one complete image data. P-Frame contains only the data that has changed from the
preceding I-Frame.
For H.264 codec, you can determine the GOV length.
If you set a recording profile with H.264 codec, the GOV length will be framerate/2.
