Re: [osg-users] [osgPlugins] UDP Video Multicast Stream onto OSG object
Hello again,
You might need to modify the address to make it work. The .ffmpeg is the
essential part.
There is a good example for files/devices in the osg cookbook.
Cheers
Sebastian
Hello Jay,
Have you tried the ffmpeg pseudoloader?
image = osgDB::readImageFile("udp://228.10.10.24:12345.ffmpeg");
image = osgDB::readImageFile( "Images/bouncing_beach_ball.png" );
osg::ImageStream* imageStream = dynamic_cast(
image.get() );
if ( imageStream ) imageStream->play();
Cheers

Hello all,
I've been scouring the forums for this answer, but failed to find anything...
So here's the setup:
I have video stream on a multicast address using ffmpeg and the following
arguments
Code:
ffmpeg -framerate 30 -i desktop -b 900k -f mpegts udp://228.10.10.24:12345
I can go to another computer on the network, open a stream on VLC and view the
video.
The question:
How can I grab that video and "display" it on an object in an OSG environment?
I know that osgmovie can read from files, but how can i grab and render from a UDP stream?
The context:
I have an OSG-based image generator for a simulator. I want to have a "hovering
screen" in the view that displays streaming video. It allows custom plugin code
written in c/c++.[/code]

I know you haven't writen getopt, I am a 20 year+ linux user and programmer I am quite aware where getopt comes from. I didn't insinuate it either :). But your getopt.c and stbool etc are there so you can compile with visualstudio since certain includes are not shipped with ms compiler. So those few files certainlyu wouldn't broke stuff for "linux people" :-). But id does not matter, let's just leave that behind.

[osg-users] How ca a subset of an vertex array marked as dirty ?
Hi, my geometry has a quit large vertex array and uses VBOs. I want to update just a small subset of the array with new coordinates and let's OSG update the VBO accordingly. How can this be done without using direct OpenGL API ? I am using OSG 3.2.0. Thank you!
