  1. Hiya guys, I have never had issue with my Denon AVRX2200W playing different formats, but run into a movie with Dolby Digital Plus (EAC3) and whilst it's playing the audio, there's no center speaker. Not sure if my amp doesn't support it, but how can I convert EAC3 to AC3? I was hoping it was something Avidemux or something could do? I don't want to change quality or anything, just convert. Step by step would be amazing.

  2. At first you can try online (real time/live) E-AC3 to AC3 conversion - AFAIR ffdshow and dedicated http://www.ac3filter.net/wiki/AC3Filter offer such feature - sadly seem both are bit outdated.

  3. If you are playing from your PC or another player that convert the audio during playback I prefer something as pandy suggested.


    Otherwise:
    ffmpeg -i "INPUT" -map 0 -c:v copy -c:a ac3 -c:s copy "OUTPUT"

    In AviDemux it should be as simple as opening the file, setting video to "copy" and audio to "ac3 (lav)", then saving (ac3 usually in mkv container).

  5. Note that eac3to can handle less EAC3 variants than ffmpeg. So should eac3to fail it can still make sense to test ffmpeg or other ffmpeg based software.
