New submission from Pieter Mees <[email protected]>:

As far as I know, it is currently not possible to have filter chains 
with multiple 
inputs / outputs.

Two scenario's that would benefit from this feature:
- Transcoding the same input file to many different output resolutions. 
Ffmpeg currently 
automatically adapts the filter chain to the size of the last output.
- Transcoding an input file to mp4 (yuv) and make png thumbnails (rgb) 
at the same time. 
Ffmpeg currently adapts the filter chain to the pixel format of the last 
output.

I would like to refer to issue #2040. As I was unable to add a message 
to that issue 
(probably due to my newbieness), I created this feature request.
