But I want to make process a bit faster, so demuxing is better idea.
I made conversion pattern. After finish foobar returns the error
1 out of 1 tracks converted with major problems.
An error occurred while transferring attached pictures (invalid box/atom header) : "E:\watchv=neE_IZYhpjs.mp4"
Also, file 5-minute file is 37 MB, too big for audio. What's wrong?
