Image sequence - feature request: add -end_number parameter

As per the FAQ ( there is a "-start_number" parameter that can be passed to start the encoding at a given frame/image sequence number.

I wish that there would be an "-end_number" parameter that could exist as well.

It would permit us to encode a portion of an image sequence.

At my studio it's normal to have 50 thousand frames in a given scene.
With that added parameter it would allow us to script ffmpeg to encode without moving/copying the rendered files selection in another folder.
The current behavior is to encode until there is no more files matching the digit (%d) parameter in the working folder.

What's wrong with -vframes?

I don't think the option would have the desired effect: FFmpeg (the image2 muxer) would stop writing files but continue to decode and encode until the input stream ends. Adding the option to the command line tool doesn't work because it does not know the start number.
Use -vframes instead.
