{{SoCProject|year=2008|student=[[User:Lukas.durfina|Lukas Durfina]]|mentor=[[User:J-b|Jean-Baptiste Kempf]]}}

== GSoC - QT improvements ==

Goals of my project:
   Fullscreen controller (FSC) for Linux and Windows
   make VLC interface for Phonon to provide it as backend
   playlist enhancements

== Repositories ==

web browsing: http://git.videolan.org/?p=vlc-lukas.git;a=summary

getting code: git clone git://git.videolan.org/vlc-lukas.git

Phonon: http://code.google.com/p/phonon-vlc-mplayer/

feel free to clone, compile, test and make feedback

== Finished (or partially finished) parts ==

Fullscreen controller

Phonon related:
* filter api, enable setting brightness, contrast...
* dvd handling, setting chapters, audio, video tracks, channels, subtitles

== Work timetable ==
26th May - start of coding

9th June - FSC should be mostly done, start Phonon part of project

9th - 12th June - one or two free days caused by bachelor exams

9th - 12th Jule - trip, with notebook, without internet connection

3th August - VLC Phonon backend should be greatly working

4th August - start coding around playlist

5th September - end of the SoC project

== Status of work ==
26th May 
           prototype of fullscreen controller is working on linux,
           but on windows there is issue with hidding of FS controller
           I requested Tanguy Krotoff for svn account in VLC(-mplayer) Phonon backend repository

28th May 
           I have account in VLC(-mplayer) Phonon backend repository
           FSC works in unintergrated and integrated video

29th May 
           hidding on windows is working, it is done by trick, but
           searching for resolving problem with hide() continue

2nd June
           remove equalizer button from FSC
           it seems nobody knows why hide() doesnt work for windows,
           so it is solved by setting opacity and resending key press
           events to libvlc

3rd June
           press events resending enabled for linux, works fine,
           now it is usable. I was trying several tests wtih transparency
           it seems to be serious problem on windows, it is blinking a lot.
           On linux you need composite manager to make it working, I dont have
           it and my attempts to make it working failed on first step with
           installing proprietary ATI driver, which doesnt want to work with
           actaul X.Org
           My work is a bit slowed-down, because I have to prepare for my exams
           on 10th June.

4th June
          add debuging mode for testing transparency on windows
          add teletext buttons
          slow hidding enabled on non windows platforms, but working
          only with composite manager and also turn on when transparency
          debug is enabled

5th June
          learning for exams, created first prototype of patch for master branch

6th June
          redesign, some tests and learning

9th June
          travelling to unniversity, learning

10th June
          exams passed, I am bachelor
          now I am going to install qt4.4 some way for fedora, it seems
          it wouldnt be easy and then try Phonon
          btw fs controller was merged with master branch and it is available
          in night builds

11th June
          some testing and fixing fs controller
          start studying and experimenting with phonon

12th June
          travelling home from university
          continueing study of phonon and related things

16th June
          start working on adding functions to libvlc interface
          for setting brightness, contrast, gamma, hue and saturation

17th June
          point mentioned above wouldnt be so easy as I thought

19th June
          these functions are done, and works correctly with phonon backend
          design of whole filter architecture in libvlc was done and going to
          be implemented

20th June
          implementing of filter architecture, start investigation about next
          point for phonon backend: DVD handling, as Tanguy said, it could be
          more complexed than filters :(

23th June
          fixing qt4 problems

24th June
          start work around DVD handling in libvlc

25th June
          fixing fullscreen controller

26th June
          studying architecture of playlist and Qt model/view

30th June
          added functions for controlling video tracks, audio device

1st July
         functions getting description about video, audio tracks and subtitles (libvlc)
         fixing fs controller => change style of initialization, now it doesnt use ugly
         hack. It is done by seeting variable on p_input_thread to signal new vout

3rd July
        new branch in phonon repo for phonon-vlc, add support for functions provided by adjust
        video filter

4th July
        first dvd related functions in phonon-vlc (subtitles, audio channel)

7th July
        continue searching solution for fs controller, add some new DVD features to phonon-vlc

9th July
        going on holiday

12th July
        comeback

15th July
        DVD handling in phonon-vlc is mostly done, I add naming of titles and chapters, fix changing
        chapters when title is change, fix refreshing audio channels and sutitles when titles changed
