Google Summer of Code 2007: Mac OS X VLC Framework

I will use this wiki page to detail the work I'll do for the GSoC 2007.

• My original Proposal

Status Summary

Task Description	Due Date	Accomplished
My proposition has been accepted	N/A	Yes 12/04/2007
Work on setting up a git server to publish my work. See Git (thanks to 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 commit 1, 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.	29/04/2007	No
Auto evalutation, keeping in mind my original Proposal: Would current VLC be able to work with the object defined? Is there any simplification possible? What changes to libvlc are needed?.	29/04/2007	-

Code repository

All the code I did for the GSoC is publicly stored on VideoLan's Git Repository for GSoC on the pdherbemont_branch branch

Interrogation

What is the best place to put the framework sources?

I am thinking of extra/MacOSX. Any better idea? -- pdherbemont. --- Nope, that's the correct place for stuff like this. Putting there a subfolder for the framework is just fine. feepk 14:26, 14 April 2007 (CEST)

Random Thoughts

VLC.app proposition

The problem

The problem with current implementation of VLC.app and gui/macosx is that it relays on the src/vlc.c common file that set up the interface. This permit to use vlc command line and do cool vlc thing with it. However there are many troubles with gui/macosx:

• It can't be detached, nor can be attached on the fly. Thus we can't really say that gui/macosx is a vlc interface module.
• There is a technical conflict with Cocoa:

 Run()
 {
     [NSApp run]; /* May not exit however vlc will cleanly ends only if gui/macosx Run() ends, so this won't work */
 }

We do:

 Run()
 {
     if(setjmp(jmpbuff) == 0)
         [NSApp run]; /* May not exit */
     /* Will exit when longjmp(jmpbuff, 1) is called, then vlc will cleanly ends */
 }

Which is kind of ugly.

Proposed solution

gui/macosx shouldn't be a module interface but instead we should create a new Cocoa application (named here VLCOSX) that links to libvlc. However src/vlc.c would be still be build (named here vlc), and we'll have in the VLC.app bundle the two binary VLCOSX and vlc. VLCOSX would start the Cocoa application whereas vlc would be the real vlc that we can use with command line. VLCOSX could still be hacked to forward vlc option to libvlc, but this is really not is goal.

libvlc advanced configuration processing proposition

The problem

Currently the configuration variable are accessible from the libvlc outside by p_main_module->p_config[item_element]. But p_config (a (config_t *) ) is a tree in list, that makes it hard to process, especially to build the advanced preferences panel.

Proposed solution

• Make config_t a tree node.
• Add the needed function to process the p_main_module->p_config list

Mac OS X Simple pref proposition

• Fullscreen
  • Display video on screen:
    • Window screen
    • Screen 1
    • Screen 2
    • ...
  • Crop video to screen size
  • Make other screen black in fullscreen
• Sharing
  • Enable sharing (enable SAP and Bonjour sharing)
  • Look for shared playlist (enable SAP and Bonjour service discovery)
• Subtitle
  • Color
  • Size
  • Effect
