[streaming] Re: Windows Selection for Streaming

[Mark Moriarty]

For streaming your screen, that's what the screen:// option of VLC does.
It cuts it up into a number of fragments, and renders it at whatever frames
per second are specified.  You must, or course, transcode, invoke a video
CODEC.

Try --longhelp --advanced, else look it up on wiki.videolan.org -- the
--screen command line switches are there.

For starters, I would normally use 4 or 6 fragments, and a low fps, say 2.
You get mouse "flicker" during the actual capturing, at least on Windows,
and cranking the number of fragments up a bit while keeping fps down
generally helps.  You can also use transcode scaling, if you would prefer to
cut the 1280x1024 (or whatever) source screen to a smaller size -- you can
transcode scale to 0.5, 0.25...

This is for use if you have a real need to stream your screen.  Depending on
what you really need to do, a remote control app like VNC (RealVNC nowadays)
may fit better.

I am trying to do something similar with VLC and that is to just stream out
what is being displayed on my local monitor. (The entire local desktop)

Is this possible?

I am guessing this would depend on what the display is outputting. For
example if it was a game that uses open GL perhaps not? Where as a
PowerPoint presentation yes? How about an mpeg video in full screen?

If your TV card supports directshow, you could use vlc to view the programs
on the PC with the card. 

If you want to stream the TV streams to other PCs, you can use vlc to stream
the content over multicast UDP and use vlc on the client PCs for playback.
Note that you can use vlc for both the client and server roles.

If I am missing some part about your setup, please send more details on what
exactly you are trying to do.
