Causes and solution(s)
In some occasions, you can have an unwanted "rtp.p_type 97" packed in your video stream.
this "rtp.p_type 97" packed can cause on some decoder Brands (for example Barco) a memory leak.
This article describes the behavior of "rtp.p_type 97" for the following 2 platforms:
-
CPP4: for example on the MIC IP starlight 7000 HD, the "rtp.p_type 97" is always active and can only be de-activated with an RCP command
-
CPP7.3: for example on the MIC IP starlight 7000i, it can be switched on when using Video authentication, but after switch off, the camera needs a restart
