I can't connect two tabs or browser at the same for the SRT

It doesn't work When I try to connect in another browser or tab, or even when I try to refresh the current page. It raises an seemingly timeout error.

astisrt: connecting failed: astisrt: connecting failed: astisrt: Connection setup failure: connection timed out

Apparently both ffmpeg and srt-live-transmit won't allow multiple persistent connections.

It's not working on Firefox/Chrome/Edge.

WebRTC establishes a baseline set of codecs which all compliant browsers are required to support. Some browsers may choose to allow other codecs as well.

You might also want to check the general support for codecs by containers.

If you're facing issues while trying to run or compile it locally, such as:

You can try to use the docker-compose, but if you want to run it locally you must provide path to the linker.

# Find where the headers and libraries files are located at. If you can't find, install them with brew or apt-get.
# Feel free to replace the path after the find to roo[/] or any other suspicious place.
sudo find /opt/homebrew/ -name srt.h
sudo find /opt/ -name libsrt.a # libsrt.so for linux

# Add the required flags so the compiler/linker can find the needed files.
