if you have suggestions on how code can be made less crappy, these are
always welcome

leaving the political stuff and the main subject of this thread for a
moment aside
technically you should be able to use swresample with libav.
If that doesnt work, iam quite interrested in bug reports
the only issue i could imagine is that you might need libavutil from
ffmpeg too, but thats compatible with libavs so it can be safely
droped in if its needed and iam not sure it is
