This post highlights the soft VCN playback.


The issue is in the live view, having a bit rate15 and reaching 25 in the IVS playback.


How to make it stable (bit rate 15)? Is this a normal situation? Need clarification on this issue, please.

Hello Nasr!

Can you please check if the camera configuration of the Video Encoding Settings on the IVS client is a Constant bit rate or a Variable bit rate?

From the IVS client, go to Devices and enter the IPC configuration. Then go to Video encoding settings, as you can see in the below picture:

Soft VCN playback-3001477-1

From the lab, we have configured it with a Constant bit rate to 25 FPS and the playback video is constant at 25FPS:

Soft VCN playback-3001477-2

Let me know if you have any additional questions.

Thank you!

Hi,Nasr.
You'd better have a screenshot so we can deal with the problem more clearly.

Can you please tell me how many video playback/live streams you are checking at the IVS client when this issue occurs ?
Also can you please provide the IPC , the VCN and the IVS firmware version? 
What codec you use and how the video is the configured on the IPC side and what is on the IVS client configuration? 
(go to Settings -> Video/audio/image -> Video settings on the IPC web interface to check).
if you check the web interface live stream of the camera where you have the IVS client installed, do you have this issue with frame rate?
