View source for SoC 2007 Project Mac OS X Framework

{{SoCProject|year=2007|student=[[User:Pdherbemont|Pierre d'Herbemont]]|mentor=[[User:Fkuehne|Felix Paul Kühne]]}}

=== Introduction ===

I ([[User:Pdherbemont|Pierre d'Herbemont]]) will use this wiki page to detail the work I'll do for the GSoC 2007. My mentor for this project is [[User:Fkuehne|Felix Kühne]].

=== Project Objectives ===

More information in [http://pdherbemont.free.fr/gsoc/vlc_framework.html my original Proposal].

=== Status Summary ===

The simple test app that links to VLC.framework is able to play a given video just fine.

I have been re-working libvlc, so that the OS X framework can be a nice umbrella over it. A vlc application could be rewritten without the need of any other VLC interface than LibVLC.

I have implemented a master-detail-view interface a-la iTunes using Cocoa Bindings, and the framework. It may be a good candidate to replace current VLC.app but it still need a lot of work. Main advantages are code base is very light. It is easily modifiable. It makes uses of Bindings (with its pros and cons).

So far I didn't complete some of my objectives for the Google Summer of Code:
* Some functionality of the framework such as media transcoding, (config) preferences tuning, and vout filter are not implemented.
* The web plugin does not take

| '''Work on setting up a git server to publish my work.'''
See [[Git]] (thanks to [[User:Dionoea|Dionoea]]).
More could be done to set up something better but that's enough for me for now ;)
 || 15/04/2007 || {{yes}} 13/04/2007

| '''Implement the stub framework and the sample code that links to it.'''
See the commit on [http://git.videolan.org/cgi-bin/gitweb.cgi?p=vlc-soc.git;a=commit;h=164ffd0787906e6b6ef1be731a450d0296fde9e9 commit 1], [http://git.videolan.org/cgi-bin/gitweb.cgi?p=vlc-soc.git;a=commit;h=72e8aa87d1f2b5249e00d596ae015b049da6108d commit 2].
|| 15/04/2007 || {{yes}} 13/04/2007
|-
| '''First draft of the headers, plus partial implementation.''' Events, playlist, vout basic usage demo in the sample code.
* We do have some draft which cover vout/playlist and shows how events will be relayed.
* The sample code is less advanced than expected but that's fine, given the wanted simplicity.
* We do have, as a side effected, implemented VLCPlaylistDataSource which is an NSOutlineView data source, and is an efficient way to display the playlist from guest app.

The RFC v2 is partly implemented. And the work is now on a RFC on libvlc playlist.

media_list, media_list_player, media_library, media_discoverer are implemented.

for now. We can use the bindings facility plus NSPredicate to imlement that.

|-

=== Todo reminder ===
* Rename VLCMovieView to VLCMediaView
* Use a 1 sec time frame for the DidChangePosition
* Make mediacontrol uses libvlc

=== Code repository ===
All the code I did for the GSoC is publicly stored on VideoLan's svn trunk (libvlc related changes) and VideoLan's [http://git.videolan.org/cgi-bin/gitweb.cgi?p=vlc-soc.git;a=shortlog;h=pdherbemont_branch Git Repository for GSoC] on the '''pdherbemont_branch''' branch. To check it out:
 $ git clone git://git.videolan.org/vlc-soc.git
 $ cd vlc-soc
Now get my branch in a new local osx_framework branch:
 $ git checkout -b osx_framework remotes/origin/pdherbemont_branch
And to keep sync-ed, tell git to use remote pdherbemont_branch for osx_framework.
 $ git config branch.osx_framework.merge refs/heads/pdherbemont_branch
And tell git the remote repository is named origin.
 $ git config branch.osx_framework.remote origin
Now a simple:
 $ git pull
Should be enough to get synced.

=== Building the framework and the test app ===
* Build VLC as usual. see [[OSXCompile| How to build VLC on Mac OS X]].
* Build the framework
 $ cd extra/MacOSX/Framework
 $ make
* Now open extra/MacOSX/Framework/Examples/test/test.xcodeproject with Xcode
* hit command-R

Voilà!
