Enhancement: Generated default output filename

[aooohan]

In most of my scenarios, I specify filename in advance when record terminal session, sometimes the name is very long, and it's a bit cumbersome and not very convenient to specify the output name frequently when converting. It will be convenient that generated a default output filename based on the input filename ; )

Is it possible ?

That's something that your shell can already do:

agg very-long-name-of-my-recording.{cast,gif}

Given you can do the above I don't see a need to implement this in agg itself.
