This is my first post, I´ve been following this topic from time ago, but this weekend I finally started to put hand on building playable DV files on my LG B7.
I tried to find an answer to my problem all along the topic, but no luck.
Everytime I used mp4muxer (any version) I get an empty (0kb) file, and I cant figured out what Im doing wrong.

In image you can see the files Im trying to use (BL, El and ac3) and the command line
what Im doing wrong?
thanks!
