[MEncoder-users] concatenate two avi files

[Rossana Guerra]

Hi every one, I have 2 avi files (videos) I need to concatenate them, but
it isn't possible, because different audio codecs.

This is the comman line and its output.

Thanks and regards

Rossana

All files must have identical audio codec and format for -oac copy.
