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

[#1]

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

	Tag Code	NumDes	Message	SNMP Support
	0x0b8e	no	no	no
	Data type	Access Level	Description
Read	t_octet	access_right_minimal	enables/disables the generation of pic info packets (payload type 97)
Write	t_octet	access_right_service	enables/disables the generation of pic info packets (payload type 97)

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

• 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
  

How to turn ON/OFF for a CPP7.3 moving camera

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:

• Solution
  
  

A camera reboot is required when an Authentication other than Watermark is toggled ON and then OFF.
