I have some videos with eac3-JOC audio and my receiver doesn't recognize that format. Its firmware is up to date.
I figure it would be easy to convert the audio to another format (with loss) but I have not been successful.
1) eac3to 3.34 doesn't support JOC.
2) avidemux converted it but the resulting mkv had a huge audio offset.

Try PopCorn MKV AudioConverter https://www.videohelp.com/software/PopCorn-MKV-AudioConverter Look under FILE Simple AudioConversionBeyonWiz V2 PVR ~ Popcorn A-500 ~ Samsung ES8000 65" LED TV ~ Sony 75" X9500H ~ Windows 7 64bit ~ Yamaha RX-A1070 ~ QnapTS851-4G
Tried the install, lots of red -- lots of missing tools (not included with install)...
Have you actually used this app to successfully convert eac3-JOC? If not, I'm not going to waste time hunting down all the missing tools just to find out it doesn't work...
Any other ideas?

JOC refers to "Joint Object Coding" which means its a hybrid that used both the standard AC3/EAC3/DD+/TrueHD AND Atmos coding sections to provide the complete sound.
You won't be able to decode the Atmos portion, as there are NO tools for doing such. Nearest you could do would be to use an Atmos decoder (in your playback device or amp) to render to uncompressed streams, and then re-capture that. This would in a sense "LOCK" it to your Atmos decoder's expected speaker layout, so not optimal to pass along to others (if that was your intention).
