First version of Kamoso 2.0 (Velázquez) released

After few months of work, we’re glad to announce the availability of Kamoso 2.0-alpha2.

Despite of being an alpha version, it has demostrated to perform quite stable in all the test we did during the alpha1 (this was a private release), in fact judging by the feedback we got

this version is way more stable than 1.0.5, so give it a try!


  • Kamoso now uses QtGstreamer
  • Improvements in the interface (by Andrew Lake)
  • New semaphore
  • Make "action" non hidden features by adding a new button to "share".
  • Added "share" button to improve feature discoverability.?
  • Better Nepomuk integration
  • No more audio/video synchronitation problems.


  • Crash when switching from "Record Video" to "Photo" mode (some times)

Test needed:

  • We need test in different environments with different webcams.
  • Take picture and then upload it to Facebook.
  • Record a video, and then upload it to Youtube

With this version we’re confident of the quality and future that Kamoso can achieve, because of that when 2.0-final is released, we will move Kamoso to kdereview, and if accepted to extragear/multimedia.

    Nice work! :)

    But the semaphore could be improved.

    • afiestas

      Any help (mockups!) is welcomed :p

  • x_fight

    a link to a site wich explain what is kamoso ?

  • fasd

    yep, this 3-2-1 animation is terrible :/ also is it possible to change treshold time? and what if i want only vlc-phonon do I need gstreamer?

  • fasd

    and about mockups, maybe something like “old movies countdown” (search youtube for it) but more polished kde4style? it would be possible to set other time threshold, I don’t know how current semaphore could handle e.g. 25s?

    PS there should be option to set the timer from 0 up to something e.g. 99s (two digits would fit into old movie countdown)

    it uses qtgstreamer or does it support phonon-gstreamer? i don’t currently have gstreamer on my kubuntu install, and didn’t want to have it just to test kamoso 2

    • afiestas

      Kamoso 2 uses GStreamer directly via Qt bindings (QtGstreamer).

      So yes, you will have to install Gstreamer.

    @Capi Etheriel
    Nothing will break if you install some MB or apps for GStreamer. Anyway, The 11.04 version of Kubuntu will have GStreamer in the CD, and maybe Fedora will have it too in the KDE spin.
