Problem with how "-an" is escaped causing ffmpeg to fail #3

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
When trying to extract a single frame from a flv, phpvideotoolkit is
currently trying something like this, notice the "-an ''"

/usr/bin/ffmpeg -i 'web/uploads/assets/batman.flv' -an ''  -ss '00:00:07.0'
-t '00:00:07.0' -r '15' -vframes '1' -y web/uploads/assets/batman-%12d.jpg

This results in the error:

If I change "-an ''" to "-an" it works okay:

Here is a patch that fixes the problem by setting argument to NULL when the 
command
option needs no argument.
