Video freeze

Sorry, the ip is incorrect, i have sent the SSH access using the form again.

We tried to start traffic dump collection

tcpdump -npi any -B 10240 -w log.pcap tcp port 554

But seems like tcpdump is not installed, and we have no sudo rights to install and launch this.
Please add user to sudoers.

Please try again.

We successfully started to collect traffic dump and restarted all the streams capturing using private IP. Will check a bitrate periodically to detect the issue.

Seems like issue is reproduced on your server after 4 hours of testing. We downloading the traffic dump and will check it.

Seems this is hardware setup issue.
In traffic dump we see big packets for all the streams every 30-40 seconds

Perhaps it is keyframe. If this cannot be assembled, a stream will freeze.
Please check the device settings: can keyframes be sent more often (every 5 seconds for example)? In this case, key frame size should decrease, then it should be less fragmented. This may prevent freezes.

We found in dump a bad timestamp sent by device: the sequence number of packet is correct, but timestamp is less than previous one

This device behaviour does not seem to be normal.
However, on our test server with latest release build 5.2.1174 such streams playing from the dump are not freeze, so problem is not reproducing. Please update to the latest build and test again.

When i try to upgrade according to the page:

Checking for updates - Web Call Server 5.2 - EN - Flashphoner Documentation

docs.flashphoner.com

i got the following error:
/usr/local/FlashphonerWebCallServer/bin$ sudo ./webcallserver check_update
cat: /usr/local/FlashphonerWebCallServer/conf/WCS.version: No such file or directory
>>> Remote version is not available, cannot check new version

How could i upgrade then?

 

[Max]

Seems like you've removed WCS.version file occasionally. In this case, you can upgrade the instance by installing a new version over the old one: Updating 5.1 to 5.2 or one 5.2 build to another

After install, the config seems lost and cannot startup, i cannot login the demo page.

sudo systemctl start webcallserver
nothing shown

pgrep -afn com.flashphoner.server.Server
nothing shown

 

[Max]

Please check /usr/local/FlashphonerWebCallServer/logs/startup.log file. If there is permission error, fix permissions

sudo /usr/local/FlashphonerWebCallServer/bin/webcallserver set-permissions

then restart WCS

sudo systemctl restart webcallserver

If nothing helps, provide SSH access to the server using this form.

i copied the conf file from old folder to the new one, then it can start up.
