Just a wild guess: how has ffmpeg been configured? If
"--enable-swscaler" is used, then the img_convert and img_resample
related code is not compiled, and sws_* functions have to be used
instead.
(note that sws_* functions can be used even if ffmpeg is not compiled
with "--enable-swscaler" - in this case, they will be emulated using the
old code)
