Samples Needed: E-AC3

May 18th, 2007 by Multimedia Mike

One of FFmpeg’s Summer of Code projects is a decoder implementation for E-AC3. Thus far, the only samples available are rips from HD-DVDs. However, according to the E-AC3 mentor/student pair, these streams are not especially interesting for building a full-featured decoder; they don’t really flex the new features presented in the E-AC3 (a.k.a. a/52b) coding standard.

Thus, I’m wondering if anyone out there has the capability to encode new samples, preferably ones that make sure of the new bells and whistles? Or if anyone even knows what software can do this, that would be useful knowledge as well.

It would be particularly arduous to have to first write our own encoder so that we could also write the decoder.

    Would the DTS HD demo disk

    Whoops meant to say would the DTS HD audio hddvd demo disc be something you would want?

    It’s worth a try. We’re not so much interested in the DTS HD part though. But, being an hd-dvd demo disc, it might have E-AC3 on there as well.
