&bc&novideo=directorsStreamID but with some extras tweaks that might be appropriate to a larger group room.
In essence, &broadcast only allows the playback of video-tracks and shared-websites that originate from the main director. You may not know the stream ID of the main director ahead of time, so this parameter handles that for you automatically as well.&broadcast flag; just one. If needing more, consider using the &novideo flag instead&broadcast to the guest invite links. You do not add this to the director or scene links.&broadcast mode, only the director is sharing video to the guests of the group room, so only the director has the burden of encoding multiple video streams and uploading them to guests. This is great if your guests are primarily on mobile-devices, have slow-Internet, or it is a larger room; otherwise each guest would be sharing video with each other guest as well.&nopreview.&broadcast disables the video from other guests, it does not disable or impact their audio, so guests should still be able to hear each other.&showlist is enabled by default for the guests, which provides a list of those in the room to the guests. &showlist=0 can hide this, when added to the guest link; useful if you want a cleaner output for the guests.&noheader can be added to the guest links, which will hide this top bar, room name and the stats.&broadcast is set. This is akin to having &style=1set.&broadcast parameter using something like : &novideo=DirectorStreamID&noiframe=DirectorStreamID&minipreview&style=1&broadcast flag is great for reducing the load on guests in a room, it will put all the load onto the director instead. &trb=2500 as an option to greatly improve the video quality. This also will greatly also increase the load on the director, so good internet and a powerful CPU will be needed. &website sharing option, can also greatly reduce load on the director and guests. The website sharing function works with other video content delivery networks, not just Meshcast.io, so you have choices.&novideo to the guest invite links if you only intend to share video via the website sharing function. This ensures the director's VDO.Ninja video-track doesn't appear, as VDO.Ninja can't always tell if a website contains a video track or not, and so may show the director's video alongside the shared website in some cases otherwise.&meshcast parameter, which sends both audio and video over meshcast in sync, without concerns of echo cancellation or audio doubling. Just add &meshcast to the director's URL to use this mode; the director's audio and video will auto-publish via Meshcast without needing to visit meshcast.io.&website parameter since a website sharing functionality has its own dedicated button in the director's control room.&meshcast, you will want to mute the Meshcast source to avoid echo cancellation or audio-doubling. The meshcast.io source page has options to do so there, but you can also add &mute to the meshcast.io when sharing it, to have it auto-mute on playback for the guests.
