We have started streaming on YouTube Live in full HD quality (1080p, 1920x1080) instead of 720p (1280x720).
We added one more 95-degree wide-angle webcam, bringing the total to 10 cameras.
Previously, the sound from the PA mixer was streamed directly via line output, but by recording and mixing the AIR (air) signal, we've achieved a sound that's "closer to what the audience hears." The audience's voices and applause are also subtly included, creating a sense of realism.
I've also set up the group so that background music doesn't play during the stream, so now I can play stylish music freely during transitions without worrying about copyright bans!
