Live video streaming getting delay due to buffering

[Pavan Kumar]

Hi Team,

We are facing an delay when we access the video streaming in the Flashphoner UI, it's getting buffering and not matching with the live camera streaming.
Delay is keep increasing over the time passes.

The configuration we used as,
Video Cam->RTSP->WCS->WebRTC->Browser

Details as below:
server use case: RTSP capturing from cameras
signs of a problem: live video buffering
stream publishing source: Ubuntu 18.04 On premise server, Browser chrome 96.0.4664.93 version
how stream is playing : Ubuntu 18.04 On premise server, Browser chrome 96.0.4664.93 version
WCS version: 5.2.1002
SDK versions used: Web SDK

server configuration:
type and count of CPU cores, RAM and disk size : 2 vcpus, 8 GiB memory , Disk 29gb
server type: Azure Cloud


Can you help on this to resolve the buffering issue.

Hello

Please provide RTSP url. We will check. If URL is public you can post it right here.
If URL is private you can send it using the report form

What is the channel between RTSP source and server?

Run on the host where RTSP source installed

iperf3 -s -p 9999

Run on the host where WCS server installed:

iperf3 -c wcs-host.com -p 9999 -t 60 -P2

So you can measure channel in megabits between RTSP source and server. If channel is not enough for your stream, i.e. Full HD 4 Mbps, it can cause delays.

Hi Max,

If URL is private you can send it using the report form

- Url is updated in report.

What is the channel between RTSP source and server?
- Each of our roadside cameras collects the images and generate the RTSP stream

Run on the host where RTSP source installed
iperf3 -s -p 9999
-We don’t know how to access the camera platform and run the iperf –s –p 9999 command

Run on the host where WCS server installed:
iperf3 -c wcs-host.com -p 9999 -t 60 -P2
- When we run the above command we didn't get any response.

Kindly let us know how can we resolve delay issue.

Thanks,
Pavan

We tried to pcapture a stream from the RTSP URL you've sent. Unfortunately, connection is not establishing:

Seems like the camera is in private network. Please provide a public RTSP URL for the camera, or provide SSH access to WCS server which can connect to the camera using this form.
