[PATCH] New passthrough implementation for AAC/MP1/MP2/MP3 support - Testers needed! - gnif - 2010-01-20 05:48
Hi all.
I am posting this in the hopes of getting some of you who have receivers that support AAC, MP1, MP2 or MP3 to test this patch set.
http://trac.xbmc.org/ticket/8575
* Adds spdif muxer to ffmpeg
* Modifies CDVDAudioCodecPassthrough to use ffmpeg spdif muxer
* Adds configure switches --enable-lib(dts|a52) to switch back to the old implementation
* Adds downmixing via ffmpeg to CDVDAudioCodecFFmpeg
* Adds AAC passthrough
* Adds MP1 passthrough
* Adds MP2 passthrough
* Adds MP3 passthrough

I recently posted a question about xbmc capability for xbmc to passtrough mp3 audio streams over hdmi without conversion in lpcm
my Denon 4308 receiver handles mp3 conversion and has a "restorer" function that improves mp3 audio. I noticed a huge difference in music quality when accessing my music library via dlna against directly from xbmc
so i'available for testing, but i'm a complete linux newby i don't know what i have to do. Have I to download a specific SVN ?
my setup is camelot on ubuntu karmic on a acer revo 3600 connected via hdmi only.

The changes are now in svn, just grab the latest revision if you want to test. It would be great if those with MP* and AAC support could provide me feedback on how well it does/doesn't work.

By the way does this mean that realtime AC3 encoding of AAC files is in the works?
thanks

Yes, its on its way

What about the low volume for down mixing is there also something "in the works"?

Reading http://www.xbmc.org/trac/attachment/ticket/8726/ac3.diff I think I found a small bug, at file xbmc/cores/dvdplayer/DVDCodecs/Audio/DVDAudioCodecPassthroughFFmpeg.cpp, line #56, it should be "memset(m_OutputBuffer, 0, ..." instead of "memset(m_DecodeBuffer, 0, ...".
Is this the proper place to report things like this one? Please excuse me if not (I'm a newbie...) Regards.

I use the Denon AVR-1909 with MP3/WMA/AAC restorer. XBMC running via Apple TV and HDMI.
Will add to feedback.
