View source for SoC 2010 ASF Demuxer

=ASF and other demuxer support=

==Abstract==
I was selected to do a project related to ASF and Matroska demuxers, but since there's some overlap related to Matroska, my main goal now is to improve both the ASF demuxer and muxer as much as I can and then find another similar project to work on the rest of the time. It's worth to note that the timeline on this website is just a suggestion, and it's no problem to work on small independent patches during the time as well. I like to do things well on the first try, that's why the schedule is not made too tight.

==Information==
I'm a student at Aalto University School of Science and Technology and I hope this is my final year here. I've been a student since 2003 and plan to graduate during summer 2010. Partly because of all this I might have some other things to take care of until the end of June. The plan is to work full time on this project from July to August however. I have a [http://juho.vähä-herttua.fi/ personal website] that I made some years ago, it has most of the useful information about myself.

== Produced code  ==

For convenience everything is hosted in my personal [http://github.com/juhovh/vlc github repository]. There are at least three branches available, plus possibly some extra branches depending on the need. The meaning of the branches is as follows: 

[http://github.com/juhovh/vlc '''master'''] - Follows the VLC master in [http://git.videolan.org/?p=vlc.git git://git.videolan.org/vlc.git] plus patches<br>[http://github.com/juhovh/vlc/tree/vlc-1.1 '''vlc-1.1'''] - Follows the VLC 1.1 in [http://git.videolan.org/?p=vlc/vlc-1.1.git git://git.videolan.org/vlc/vlc-1.1.git] plus patches<br> [http://github.com/juhovh/vlc/tree/libasf '''libasf'''] - Branched from VLC 1.1 for now because it's more stable, will contain experimental ASF code 

The new code will first enter the ''libasf'' branch and when it's stable enough I will port it for the 1.2 version and push to ''master''. The main idea is to have only that kind of code that can be merged to upstream is in ''master'' and ''vlc-1.1'' branches. The ''vlc-1.1'' branch is mainly for patching possible small issues that come up in VLC 1.1 or backporting changes from ''master'' when appropriate.
