x264 future audio integration
« on: February 22, 2010, 05:26:53 PM »
Well, i think is good to have people  discussing the good (quality settings) and bad points (bugs, hacks ) in current audio libraries.
That said i want to bring a recent thread in Hydrogen audio about the status of the release libvorbis 1.3.0. ;D

Everything in the AoTuV tunings 5.7 will be merged into the main line source for the next major release of libvorbis 1.3.0. That's about it.

Also there's no optimized aoTuV Beta 5.7 (libvorbis 1.3.0.), the most recent is just a port of 2006 Lancer's to Linux.  Even not accelerating the last tunnings the build is about 3x faster.

The_Sven has produced an aoTuV Beta 5 binary build of Lancer (as of 2009) with optimized SSE instruction sets that has been compiled for Linux. It runs about 3x faster compared to the standard AoTuv Beta 5 build and is a 32-bit x86 binary.
This static GCC 4 binary was compiled by The_Sven.

Link to The_Sven's repo:  http://repo.or.cz/w/vorbis-lancer-gcc.git/

EDIT:    Well, sorry, Let me make it clear.

3.  Audio encoding support through libavcodec, probably using libvorbis (for MKV) and ffmpeg aac (for MP4).
(Time scale: 2-4 months)

 I'm just trying to agreggate info so it's easier for everyone involved in such endeavour.

EDIT:    Monty's back to Vorbis development.  http://xiphmont.livejournal.com/48207.html

What were you trying to say about x264?  Anyway, thanks for pointing out that aotuv will be merged into libvorbis releases.
Knowledgeable about: cmd.exe, ffmpeg, x264
