For personal reasons (i wanted a audio/video stream where all are in a real sync) i have setup a server for can stream in SL webM videos (as explained at https://slmusiclab.wordpress.com/2024/04/24/vjing-live-and-in-sync-in-second-life/.
The system work well, all can see and listen the stream with pre v.7 viewer, but viewer 7 don't show the video. Connection with video source is made with a simple URL, nothing strange or difficult.
What expected: same behavior on all viewers
What happen: V. 7 viewers don't show the video. They make connection with server but screen remain black (i tried LL viewer, Firestorm and Alchemy).
BUT
If i apply the media URL to the dedicated face of a MOAP with v. 7 viewer, then also the v.7 viewer work.
