[GTALUG] Bash Problem

[Stephen]

I am new to Bash scripts.

I am trying to create a script to use avconv to convert mkv files to mp4 
file.

Run one at a time the command runs fine.

When I execute this script I get an error about an unknown parameter. I 
am guessing that the expansion with the filename variables is failing.

Can someone help me correct?

Thank you!

#!/bin/bash
# Usage: convert file to mp4
shopt -s nullglob
ext='.mp4'
for f in *.mkv
do
    base=$(basename $f .mkv)
    nFname=$base".mp4"
    echo $nFname
    avconv "-i $f -c:v libx264 -c:a copy $nFname"
done
