3GP delegate? Expect FFMPEG but is not?

[Swoops]

Hello, I am trying to make a thumbnail of a .3gp video. This works fine with FFMPEG but I want to use IM. However it seems IM is not delegating it to FFMPEG. Is this correct? Or am I missing something?

Try this: convert mpeg:myvideo.3qp image.gif. Does that work?

Works perfect! Cant thank you enough.
Had to add the prefix, yes. I take that is to force a delegate?

You'll find implicit support for 3GP in the next point release of ImageMagick. No explicit mpeg: tag required.

Thats wonderful news. Waiting for that instead of refactoring code for exception. Thank you so much.
