Connecting and disconnecting IPCAM with passing parameters to the URL

Issues developing apps
1

When connecting the IP camera with the transfer of parameters to the URL, then openly cuts off everything that is transmitted after the “?” After a lot of trying, I replaced this character in the string with “%3F”, and it worked. BUT there was another problem. Now, when you disconnect the connection of this camera with the transmission of the CONNECTIONID, which contains the character codes, it gives a 404 error, but if you replace these characters back, it immediately truncates, which leads to the same 404 error.
Therefore, I can turn off the camera only by turning off the conference.

I’ll show it differently

You hit a bug when camera URL contains ? character.

We will take a look…
