<p>add proposal</p> <p><b>New page</b></p><div>; Summary : Create an OpenSource Bluray decoding library<br /> <br /> ; Proposer : Benjamin Zores<br /> <br /> == Description ==<br /> With recent video decoding acceleration features (VDPAU, <br /> VAAPI and multi-threaded/core decoders), Linux now can compete <br /> efficiently on HomeTheater PC (HTPC) and embedded multimedia SetTopBox <br /> market.<br /> <br /> One remaining drawback is the complete lack of Bluray movies decoding <br /> support. While nearly all video player (FFMpeg, MPlayer, Xine, <br /> Gstreamer, VLC) now are able to demux and decode H.264 &amp; VC-1 MPEG-TS <br /> streams found on Bluray discs, none of them is able to directly read<br /> and decrypt content from an original disc.<br /> <br /> This idea is to create a Bluray access and decrypt library that could be <br /> commonly used by all players. Several steps are required to do so:<br /> * be OS portable and written in C, with embedded constraints in mind.<br /> * support AES, SHA1 and ECC decoding, preferably by native implementation or through GnuTLS.<br /> * decode MPLS playlist file format<br /> * support [http://en.wikipedia.org/wiki/Advanced_Access_Content_System AACS] protection<br /> * support [http://en.wikipedia.org/wiki/BD%2B BD+] protection<br /> * support [http://en.wikipedia.org/wiki/BD-J BD-J] protection (hard, due to JVM)<br /> <br /> Such a library has been initiated but development seems discontinued.<br /> <br /> == Related work ==<br /> * libbluray: http://my-trac.assembla.com/libbluray/<br /> <br /> == Funds ==<br /> * Sponsor Bluray drives to developers<br /> * Buy Bluray association specifications (including protection mechanisms).<br /> <br /> == Scope ==<br /> * Write a new lib based on existing work<br /> * Polish its API for extensive media player projects usage<br /> * Extend the on-the-fly decryption algorithms.<br /> <br /> This should probably take up to a year of development and tests.<br /> <br /> === Interested parties ===<br /> * Various people from GeeXboX project team already interested<br /> * Probably random developers from MPlayer/Xine/VLC/Gstreamer projects.<br /> <br /> == Comments ==<br /> <br /> [[Category:Project proposals]]</div>
