You must be an experienced in libavcodec

I need to make a wrapper for libavcodec library that will create encoded video from images.

I need following api:

start(filename, framerate) - initializes video codec and prepares system for adding images to video

addFrame(*data) - add a frame to video "on the fly" as known structure of fixed resolution

finish() - closes the file and cleans up

currently i save the images and use:

ffmpeg -y -report -f -image2 -framerate 40 -pattern_type sequence -i %[url removed, login to view] -vcodec -libx264 -crf 30 -preset fast -r 40 OutputDirectoryName/[url removed, login to view]

command to generate video

I want to get rid of necessity to save image files. I'd like to start encoding process, provide the process with frame data one by one (asynchronously), and finilize the encoding.
