How to stop 'rtp.p_type 97' (OSD or Video Authentication packet) on a CPP4 and CPP7.3

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

Payload Type 97 - RCP+ command to disable/enable the generation and transmission of those packets:

RCP+ CONF_PIC_INFO

This RCP+ command was added and available since firmware version 5.80 and per the RCP+ documentation it is still applicable for CPP4 firmware version 7.10.

After sending this command, the “rtp.p_type 97" packet stops

• Off> http://ipaddress/rcp.xml?command=0x0b8e&type=T_OCTET&direction=WRITE&payload=0x00&num=1
• On> http://ipaddress/rcp.xml?command=0x0b8e&type=T_OCTET&direction=WRITE&payload=0x01&num=1

Note:

• As its on by default, it will also turn back on after factory reset
• Once it is turned off, it will also remains off after a reboot

When choosing the Video Authentication option "SHA-1" , "rtp.p_type 97" will be added to the video stream
But when you turn it OFF again "rtp.p_type 97" will remain ON and doesn't stop, until you have restarted the camera.

• "rtp.p_type 97" stream should stop when switched off

Despite the fact of disabling OSD, telemetry feedback, timestamp, and watermarking, the “rtp.p_type 97” continues:
