Re: Media on a Prim - many video/audio streams

Unfortunately this is not just limited to Media On A Prim in Secondlife.  It
also extends to sounds i.e. in breedable pets such as horses.  Unfortunately
as a region manager in Secondlife I get these kinds of complaints but the
only way I know to correct it is in the script itself.  There is nothing in
the region manager that can fix that or really in about land.  

As for in opensim I think it's the same thing as I don't recall seeing
anything in the Opensim.ini file or region.ini files that solves that but I
could be missing something there.

I also recently had to have a couple residents on the region in Secondlife I
manage both own their parcels and not deed to group.  This seems to help a
little bit.  Might also try changing the channel your script operates on
including the  ranges in distance the script works in.  It may or may not
help.

I hope that helps a little bit.

Emperor

This is really a general Media on a prim query... rather  than being OpenSim
specific, so please excuse the use our of mailing list here... but I thought
I would check what the experience of others here in the OpenSim community
is... as it seems to be a real problem...

We have noticed that on our Virtual University of Edinburgh regions in
Second Life and OpenSim where many students set up MOAP screens in gallery
spaces for their projects that the media playing (often YouTube videos, etc)
appears in the "playing" list in viewers and we get perhaps 30 to 40 ites in
that list which seem to fight to play...
These leak across into adjacent plots even when play sounds and so on are
limite dto the plots.  But we even notice it can leak across REGION
boundaries in Second Life which seems odd.  It seems that a plot owner
cannot control sound coming INTO their plor or region.

Anyone else noticed this or seen on-line discussion of the best fixes?

Re: Media on a Prim - many video/audio streams

In principle it might be possible to get the MOAP module to not serve shared media surfaces to users in other plots but
this wouldn't work if the avatar was crossing plot lines (since it would already have the data).

I think one would really need the viewer to actively drop MOAP surfaces in other plots (in which case you wouldn't need
any simulator-side changes).

I would actually be kind of surprised if there isn't a TPV that offers something like this, since MOAP is heavyweight
and afaik the display limit is 5 surfaces.  But I haven't explored that.

This question actually finally triggered me to create a crude diagram of how MOAP works [1], namely that the
communication is directly with a website.  But I don't think that actually has anything to do with this question.

Re: Media on a Prim - many video/audio streams

In reply to this post by emperorstarfinder
Thanks Justin and Emperor.. good to know its a problem others have
seen.  As Justin shows, MOAP is definitely served server direct to
user like the media URL.

The MOAP URLs all show in the list of media that can "play" in the
viewer and it gradually fills in from adjacent plots and regions even
if you never visit them or cross plots.  We have two adjacent regions
with student project galleries on them next to our main meeting area
in the corner of one of those regions and we see perhaps 30 to 40
URLs in the play list.

As Justin said only 5 or so play at once?  Empirically by observation
I thought I was seeing 5 to 7 at any one time fighting to start up as
I move my camera around... so Justin might be right at a limit of 5?

Its a real pain as we get a cacophony of youtube video sounds while
in a seminar on our main meeting space.  You can find all the sources
with the icon to locate a MOAP generating prim... but to go there and
turn them all off (even where you do have permissions) took me over
an hour yesterday!
