Problem with E-AC3 from Blu-Ray
This is totaly shame, none of current demuxers (TsMuxer, eac3to) not recognizes Blu-Ray E-AC3 wich have embedded AC3 core same as TrueHD. Good thing is that, these blu-ray's are only few, but E-AC3 is allowed as primary audio on Blu-ray's and very good replacment for crappy DTS and direct opponent to DTS HR which aslo need core, but Dolby Digital need much less bitrate IMHO.
Only one demuxer, DGIndexNV can extract raw E-AC3 with core. Did somebody haved same expirience, and what is possible solution for manipulating with that streams, eg. extracting core or leaving only e-ac3 part. Since Eac3 can't manipulate. Good thing will be that we can join e-ac3 part with ac3, like is possible with truehd with eac3to Thanks |

It's region B, but titles are not on English, few east movies.

Thanks for the sample. It is the best I've seen so far of ac3 independent stream core+eac3 dependent stream, although I do wish I could come across something other than a Dolby demo. It really isn't worth it to spend the time to implement something if the only use is for testing purposes. It would be awesome if you could provide a clip from an actual movie. I don't care what language it's in.

The dependent stream (the E-AC-3 part) can either replace the core channels, add to them, or do both. For example, the core could be a 5.1 downmix of a 7.1 stream, then the dependent stream could contain replacements for the 2 core surround channels, plus the extra 2 rear channels. The decoder would have to sort all this out. Quote:

Use Neuron2's DGSplit 1.1 and cut a 50 MB chunk.
