Hi Pete,
What exactly is the error message you're getting when it fails? I may
be wrong, but I think it's trying to call ffmpeg without a file path.
I say that because, based on my rudimentary understanding of Ruby, the
mp3 object doesn't exist inside the scope of convert_mp3.
So instead, try something like this:
private
def convert_mp3
system("ffmpeg -i #{self.mp3.to_file.path} -vn -ar 44100 -ac 2 -ab
64 -f mp3 #{mp3.to_file.path}")
end
(I recommend putting that inside private for security reasons.)
If that doesn't work, try to copy-paste the command itself into a
shell, substitute the filename for something you know is there and
should work, and try that. In other words, try to isolate where the
problem is - in the code, or in the execution of ffmpeg.
