AC3 and Passthrough on the AppleTV and Macs

Posted by Thoughts and Ramblings on Saturday, April 7, 2007

A few days ago, I managed to get my AC3 codec to do AC3 passthrough on the AppleTV. It wasn’t that hard once I stopped making stupid mistakes. Now, if you have a video file with AC3 audio along with a dolby digital decoder, you can play it on your AppleTV and enjoy full 5.1 dolby digital surround.

David Conrad later sent me a patch to make it work on PPC based macs. It is annoying not having a decoder to test these things on. I suppose that just adds to the challenge.

The released version will be 1.7.5, and I have it slated for the end of the month. It may be sooner, but for now, that is my release date. Maybe I will add in Dobly Pro Logic II to this release as well (already supports Pro Logic I).

Graham I appreciate all the work you are doing with the codecs - thank you. Just one quick question - to enable AC3 passthrough where can i find: The key “attemptPassthrough” in “com.cod3r.a52codec” must be set Thanks
