In the GUI I am using I don't see amrnb,
as a choice for audio.
I do see libopencore_ammb
Maybe the GUI has a typo in the list?

I want to convert a vob file,
to use on a cell phone (3gp)

I have done this with DVDx 4,
but the sound was poor.
So I increased the quailty in that software.
But the video size went from 320 x 240,
To 384 x 288.

So I then ran it through FFMpeg using a GUI,
in Linux to reduce the video back to 320 x 240.

I would rather just use FFMpeg and skip DVDx 4

Thank you for helping me.
