    Phoronix: Ubuntu's Mir Works Towards Screen-Casting Support

    Mir, the display server currently powering Ubuntu Touch and will be on the desktop side with Ubuntu 14.10, is working on its screen-casting support...

    Sounds like a nice feature to have built natively into Mir itself.

      I hope they include or expose the ability to capture screen video and audio(assocaited with that screen), so Mir can have a built in FRAPs or have a FRAPS made for it easily.

        I really hope Mir-grabbing support can be written for FFmpeg. It would be nice to record a OpenGL games and applications.

          screencasting in display server? shouldn't this be in compositor? both wayland and mir already treat clients like sinks if i understand correctly, which would also mean you could enable screencasting in any compositor simply by using infrastructure they work on

            Not if you want to support casting full-screen apps.

              NSA

              Under the current NSA-infiltrated world, are there safety measures that stop institutions such as the NSA from using such recording features to spy on computers?

                It's called a firewall and good safety measures.

                  Have you seen the presentations on how fully the internet and many tools have been infiltrated?

                  a firewall is not enough and good security measures would involve checking that your computer case has not been compromised along with any wires, ports or connectors. Or any custom additions to the motherboard. Removing any wireless connectors and then not plugging it into the internet.

                  Even then chances are the system can be compromised.

                  The NSA slides promised that most technical equipment was compromised especially iphones which would be infiltrated "all the time, every time"

                    therefore open hardware..?

                      correct me if i'm wrong here. screen casting is no different than remote access, except the fact that one translates it into something like RDP or uses video compression and forwards it to a client like twitchtv, where only difference is that second doesn't need to handle a lot of things RDP must. as much as i looked up wayland remoting, they are using wayland proxy server in order to dispatch those to compositor, being that remote or not. nor did i see any "hey, doesn't work with full screen"

                      stacking the whole screen casting thing (casting selection, video compression, network protocols...) into display server is about the same as car putting engine on the key. all well and swell, except your key now weighs a ton and it is hard to put in your pocket.

                      either that or whole this article is misleading and mir just prepares easy to plug in setup same manner as wayland proxy, which makes whole mir reasoning even more moot

                        Ugh! Here comes paranoia and NSA...

                          Mir and Wayland work in different ways.
                          Wayland is no display server, it's just a protocol to describe how programs should talk to the compositor.
                          Mir is a display server and the compositor is a client that connects to Mir. With this approach you can redirect
                          full-screen apps directly to the display server which gains some performance but gives the compositor less control.

                          And yeah what this is about is an interface to provide the rendered frames to a client. If the client uses this for
                          creating a screen cast video or implementing RDP doesn't concern Mir.

                            might make more sense to present screen casting as possible usage than as full screen casting inside display server. the original presentation smells like bloatware to me. not to mention it is heavily misleading

                            but, hey... that's just me and my 2 cents

                              Is that you mr Stallman?

                              But to be honest, I am steering clear of vPro Intel boards
