SoC 2007

Reflexions for Google Summer of Code applications.

Introduction & Informations

This wiki page deals with VideoLAN attempt to be a mentoring organisation for Google Summer of Code to improve VLC media player.

VLC media player

VLC media player is a Multimedia player, encoder and streamer platform independant application. It is one of the best succesfull open-source project without any profesional structure underneath.

VLC media player is downloaded at an approximate rate of 4 millions every month from the main website (does not include unofficial mirrors and package distribution), which means about 30 millions people have downloaded VLC 0.8.5 from the main website!

You can have more information on Wikipedia or on this wiki

Summer of Code

We would like to be a mentoring organisation (mentors on SoC Website).

If selected and developed, SoC ideas will be included in VLC media player 0.9.1, under the GPL licence. 0.9.0, next version of VLC should be out before the summer.

Ideas

Read this

We (the VideoLAN team, and [[User:J-b|jb], the writer of this page) have architectured this page in two main lists of idea. The first ones are the one we would like to focus on, and seems key projects for VLC and a lot more fun than the others; and other ones that are less detailed but could be good ideas too.

We don't want to impose anything. This is free and Open Source software.

If you don't want to apply for SoC but want other ideas, check the Mini Projects page!

Proposed ones

GUI intfs for the browsers plugins

This project is about adding interfaces possibilities to the browsers plugin in order to have a correct embedded mode inside webpages, with buttons to control VLC.

The second part of this project is to provide a replacement for all preconfigured media players embedded in webpages. Instead of having youtube player, windows media player, quicktime player or any other, VLC can take their place. A better suited cache handling module access is also needed.

Proposed mentor: Quovodis.

Fullscreen Controller

This project would provide a fullscreen controller for Linux/Unix and Windows, as VLC media player already has on MacOS X.

It should be draggable, clickable and support the classic buttons.

Proposed mentor: Dnumgis

Subtitle support

This project would rework the subtitle infrastructure and freetype module in order to read more subtitles:

• support for SSA/ASS using libass or asa,
• support bold, italic, underline, RGB colors, size changes and font changes for a whole line or part of one line.
• support for the HTML tags, and add all the useful subtitles types that are not yet in.
• capability of moving the subtitles in the picture,
• capability of displaying two different subtitles, with no overlap,
• capability of displaying subtitles with no video enabled for audio books,
• support for Karaoke subtitles,
• ease the automatic extraction of subtitles.

Vista acceleration and DirectX improvements

Support for EVR for rendering in windows Vista and make it default for Vista. http://download.microsoft.com/download/5/b/9/5b97017b-e28a-4bae-ba48-174cf47d23cd/MED134_WH06.ppt http://msdn2.microsoft.com/en-us/library/ms788119.aspx

Rework and ameliorations of DirectX Video Output modules for older versions of windows and/or DirectX.

Proposed mentor: Quovodis

MacOS X

Create a VLC framework that can be used by both VLC.app and VLCplugin.bundle. Adapt and use Leopard enhancement in VLC

Proposed mentor : TheDJ

Other Ideas SoC 2007

BDA Drivers

and TV stuffs for windows

Subtitles support

SSA, freetype, whatever

Preferrably incorporating either the libass (http://sourceforge.net/projects/libass/) or asa (http://asa.diac24.net/Main_Page) libraries instead of writing our own.

OSX Leopard support

especially: QTKit Capture API, Resolution independence, iChat Theatre

Mac OS X Framework

Create a VLC framework that can be used by both VLC.app and VLCplugin.bundle. (Trac Ticket #739)

Matroska (mkv) muxing

robUx4 can do the mentoring. He already wrote the demux and knows mkv really well. Sounds like a nice SoC subject. http://forum.videolan.org/viewtopic.php?t=33015

Hint MP4/MOV Files

Add video and audio hint tracks as the output file is muxed. Resulting files can be streamed from RTSP server with trickplay, like DSS/QTSS. Probably requires use of GPAC libraries.

Extract Subtitles

It would be great to have an easy way to extract subtitles from all the types of embedding used in different formats of video streams. DVB, line 23, etc. Google could be interested because it's a really hard, but discrete task. And who wouldn't like search google videos with text.
