HD audio bitstreaming?!!

Hmm, i think topfs2 meant that it will be merged once it`s capable of bitstreaming the core audio (DTS/DD) like the present implementation, and HD audio can be worked on afterwards, until the final Eden release. Or at least that`s what i understood from his post.

I meant when core audio (alsa or directsound for osx) then its ready for merge, or atleast review.

Issues I'd personally like to see tackled (either by me or someone with more time available), here goes:
- Regression of http://trac.xbmc.org/ticket/9248 (probably want to make the Sink have the channel layout from the AEStream if available; things get more complicated when upmix support is added as then we wouldn't necessarily want this always-on anymore)
- Regression of http://trac.xbmc.org/ticket/10297 (FMT_RAW should probably be splitted to LE and BE varieties so that AE can handle byteswap as with other formats (or alternatively use AE_FMT_S16LE/AE_FMT_S16BE for raw as well and instead use m_encodedFormat != AE_ENCFMT_PCM to flag encoded audio), and we can query CoreAudio for the endianness it wants)
- Regression of "Changed SL & SR channels to be forced to BL & BR when the source does not have BL & BR channels and the speaker layout does not have SL & SR" (i.e. this doesn't happen anymore; originally added to master in fcb1658d6) (should be a simple matter of mangling the channel layout a bit)

AE's usage of LibTag needs addressing.

wow it uses that?! Don't really understand why it would need that?
- jmarshall - 2011-04-05 22:59
It doesn't. I thought it was in a separate branch. If not, it should be.

Are you talking about not merging AE with the main branch?

Are there any open issues with the Windows implementation? As I understand it, on Windows, XBMC will be using FFDShow like MPC ala: http://www.mediasmartserver.net/2010/02/02/guide-setting-up-bitstreaming-with-your-windows-7-htpc-part-i/
Other than that, AE just needs HD audio codec detection and GUI options for bitstreaming (again this is just my understanding from reading the AE threads, I'm not a dev).
I'm currently running on the Windows nightly builds, and am very much looking forward to being able to test these features out

ffdshow will be used on the dscodec development. It's a separate project.
AE will include HD audio bitstreaming however it will be native to XBMC.
