I'm not even sure I know how to properly ask this question, so forgive me for that and that variations of this question have been asked and answered so many times over the years, I'm not sure which one applies. Some TV's in Second Life - or more accurately their routers - will set a parcel media url based on whatever url is playing through the device and then some version of media on a prim to display on multiple screens/surfaces simultaneously. As parcel media, this allows everyone on the parcel to watch the same movie, for example, roughly in sync. VEA TV's do this. They're the only ones I've found that do. They appear to be deprecated though - still looking for Flash I think - and I'm not sure they're still maintained. Others can do so via livestreaming - OBS for example - but that requires more computer resources than seems necessary and runs a higher script load on my parcel for each screen broadcasting. What I'm trying to do is movie night, showing the same movie on eight screens simultaneously for everyone on the parcel to watch roughly in sync, as much as possible with different connection speeds and such. My question, as well as I can ask it, is how does one make media on a prim (or mesh) work with parcel media, and secondly how to make an object set and change the parcel media url based on the url sent to the object for playback. Again, apologies if I was unable to find where this question has already been answered.
