One can build a video file from a group of images, like this:

      ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi

... but that's now that I want!
I want to feed the data from my application directly to ffmpeg, without 
encoding it into JPEG, and writing it put to a file.

(The purpose of this is to get smaller latencies and better throughput.)

Thank you:
