Screencasting on Linux


Is it possible to have a software to capture your screen every second and allow other people to "stream" it?



Much thanks in advance!

Yes, one of them is VNC.

Mind you though, it's not a very secure package.. so better use it over a tunnel (ssh e.g.), towards the viewee..
(a trusted person, which can login through ssh, en then connect to vnc)

or use a vpn connection.. (like openvpn)

another option would be to share an X session. But that more complicated to setup then vnc.
(and depends on whether the viewee is on a Linux host or not, if it is possible (e.g. x session sharing cannot be connected to, from a windows host afaik)

What if my box doesn't have a graphical interface? And say I have a program running, I want to capture just the GUI of that program, can VNC work without a Gnome interface?

in case of a console only, you could use "screen" to share the view.

man screen is your friend (asuming it is installed)

But the problem is VNC doesn't output to a streamable video format such as Windows Media Player format. How do I go about allowing people to stream?

Is there a way to allow them to stream without having VNC client? Like outputting it to a streamable video format?

there are a few desktop recorder packages (for both Xsessions, and terminal sessions) that can record it to a video file.

RecordMyDesktop is one (for X sessions, gnome based, pretty good)

-----------
For terminal only.. i cannot find one decent/easy to use/quality labeled one.
-----------


However, as mentioned above, you have the program: screen
This allowes to share a session on the terminal with others.
The viewee only has to connect to you through ssh (in case of windows: putty is a very small, no install need, client for ssh and other protocols), and then he/she can hook in on screen (with correct parameters) and view/interact LIVE with what you're doing there.
The only thing is, it won't record it to video.

Look up in google: linux screen share terminal session
or something like that (anyway the words linux, screen, share are vital keywords in your search tries).. there are a lot of tutorials/howto's about that (i saw with a few quick searches)

hope this provides a satisfying answer.
