As far as I understand this can be done with an OSC Multilistener also, if we are on the same network.
Can you share the .mp4 with me? DM me with a file share link if you can, and I will convert to HAP and test. The file should stream, but yes, it will be very large.
@dusx I tried converting the file to the HAP codec with Shutter Encoder. The MOV file turned out huge (25 GB) and it won't open in any software, not even Isadora or VLC. I also tried converting to Apple ProRes, the result was the same. Is there anything else I should install?
Love the fact that you are still hosting these meet-ups :)

How I wish you could stream these open studios, even in the most basic of ways.
Unfortunately, I'm not at a podium with a screen behind me giving a presentation or anything like that; I'm walking all over the room helping people and explaining things, so there's not really a way to get any good video angle nor a way to get a good audio feed (wireless lav and a mic capable of covering a whole room are not kit I have access to).

file format is MP4
MP4 is not a good format to use this approach, since the position input of the movie player is being set, this doesn't allow the multi frame decompression used by MP4 to work as expected by the codec.
Try transcoding to HAP, that is the best format for dynamic playback.
There is no link to the App. We will need to understand how this is providing the lyrics to you?
How I wish I could join you!
