[FFmpeg-user] Help with converting .avi to mp4

[Jeff Parkes]

Hi, I'm new to FFmpeg and am struggling with the correct syntax to use 
for "input_filename".

I'm trying to convert a film in .avi to mp4, which my TV can play. I 
keep getting the message on my Ubuntu terminal; <No such directory or 
file as "Input_.avi">. I have changed the name of the file to "Fred.avi" 
for ease of use but still unable to convert. Your help would be 
gratefully received.

Regards

Jeff Parkes
