Hi

Thanks for this too.
I was confused by this "mixlev" switch, believing that center and surround channel will be encoded by this gain.
Now I see gain info only stored in AC3 header as a message to the decoder "apply it in case of stereo downmix".

Concerning Dolby Digital Plus, I will check whether 7.1 channel from DTS-HD MA can be encoded to lossy EAC3 correctly.

EDIT: Now It was tested.
Input 4887kbps@7.1ch.
This switch used:
Code:
 stdout.w64 | ffmpeg -i - -c:a eac3 -b:a 1344k %_.eac3
Output 1344kbps@5.1ch.
I lost the extra channels.

bye
