(btw, could you please name it?). Besides, just like .dca (DTS "coherent acoustics"), the .eac3 compression has no predefined set of "allowed bitrates". |

The procedure started regularly with the set bit-rate value. The only limitation that the maximum number of channels that can be managed is 6, the initial test track is 8ch (7.1). I don't know how it is possible to manage 8 ch tracks. Last edited by DMD; 25th March 2020 at 20:32. |

I had a go this morning trying to generate an 8 channel EAC3 encode using an 8 channel PCM source. I also obtained a 6 channel EAC3 elementary stream.

As a bit of an addition...
I also created a 6 channel EAC3 encode at 1536 Kbps using one of my DTS audio CD's as a source. And I have to say that the playback results are very good indeed.

The reason why ffmpeg won't encode E-AC3 with >6 channels is not really obvious to me. And I am obviously wrong with my guessed reason...

Thats as logical a reason as for anything. People usually work on one of two things: Stuff they have a personal interest for, or stuff other people pay them for.

In my opinion 7.1 don't offer a better 2D surround than 5.1, I think is a commercial placebo, then for me is ok the ffmpeg behaviour.
Other question is Atmos 3D surround.

ffmpeg will not support eac3 7.1 encode, just forget it and go
my question: is it possible to cut the end of the file using eac3to? like cut 10s, we can cut the beginning with simple -10000ms but.. anyway for cutting like this ffmpeg is pretty handy, eac3to doesn't come with this function i guess Last edited by justnobody; 24th April 2020 at 20:40. |

Not sure for eac3to, but I use mkvtoolnix to losslessly cut any audio file. Just mux it to MKA, and use the Split After specific timestamps feature (in the Output tab) to split it where you want. Then, you can extract the part you need from the MKA segment with gMKVExtractGUI.

If you know the movie length, for instance 1:50:40.000 you can cut the 10 last seconds with:
-edit=1:50:30.000,-10000ms EDIT: to slow to make the test

People will pay IF:
1) the price of the new encoder is lower than the price of the "official"/certified encoders && 2) the price of the new encoder is declared publicly; I mean, no "send me an email and I'll tell you how much it will cost", alright |
