[FFmpeg-user] do a composite from a bitmap and a video file

[blofeld]

hello,

i am supposed to do a simple editor in which a composited video has to be
generated from a useruploaded video file and a background bitmap.
inside the editor the user is able to rotate and scale the video and then
place it at a certain position inside the background
then the backend has to encode a new video with the whole composition.
since the frontend is not able to do the encoding itself, i would like to
pass the backgroundbitmap and the source video to the backend and make it do
the rotating/scaling, placing and rendering acording to some kind of config
file.

is this possible with ffmpeg?
thanks a lot for any input, and have nice holidays!
