Hello!

I'd like to stream multiple portion of one video source into multiple out streams. It sounds strange, but here is an explanation image:


So there are two viewport (#1 and #2) and I'd like to stream of this to viewport into two different out stream.

But the task is a bit more complicated, because of these viewports are moving during the streaming


I need to move viewports like an animation ... for example along a spline path. The viewport's dimension not changing by the time only the position.

My questions:
#1 Could libvlc streaming two stream from one source by viewports?
#2 Could i reconfigure the viewports position during the streaming without flickering or lagging?

Is this task mission impossible?

What if i just give up the viewports movements and streaming only the standing viewport streams synchronized?

Ok, I give up the movements thing.

Now I have viewports with fixed position and sizes.

I've sliced the original video into more videos with "cropping" : vfilter=croppadd{croptop=490,cropbottom=490,cropleft=760,cropright=760}

Every video send through RTP stream in a local network: How can I syncronized c0,c1,... media streams?

I read about "network synch"(?) modul in VLC 1.xxx(?) but i can't find in VLC 2.2.4...
