RE: [jitsi-dev] FW: [jitsi/jitsi-videobridge] channel-bundles suddenly empty after patching conference in 1055 (#680)

Hi Damian,

Sorry, I’m only seeing now that you wrote.

I’m not saying that channel bundles ever made sense but changing this now will break a lot.

Could you please give a top-level overview of what exactly was changed. This is how a new conference in 1011 looks like. channel-bundle-id is a string which points to the id in the channel-bundles array.

If I understand the code correctly, you have moved everything from channel-bundles (here: the transport object) into an endpoint object like here (channel-bundles-id removed, endpoint is now an object which contains the appropriate element of the channel bundle)?

What happens when we have multiple channels (video, auto, sctp)? Is the endpoint information repeated or does it only show once?

Thanks,
