Details

Enable decoding DTS and DTS-HD streams with the new libdcadec library. This allows sending uncompressed LPCM streams of DTS-HD lossless audio.

This is a huge improvement over decoding the lossy core audio codecs or bitstreaming the lossless codecs. Decoding on the PC allows resampling and other parts of the audio filter chain.

Has dcadec had a stable release?

Define stable. It works for me compiling against ffmpeg-git.

Let me expand, I believe decoding DTS core still works the same as with the old libdca (VLC). This would merely add support for the extensions to be decoded should that be desired.

In that way, I don't think it's an incredibly risky addition.

Stable as in the developers say "here is the 1.0 release", not building from git head

Nothing like that yet. The developer has said "soon" though, so we'll see.

Things very rarely go into the repos without a stable release.

dcadec isn't going in [extra] without a stable release. I've had my eyes on it for a long time, but "soon" was 3 months ago, so who knows when there will be one...
