Всем привет.

Вот такая ситуация:
с одной стороны, надо включать в ffmpeg поддержку swscaler.
с другой, если ее включить, то все становится плохо:

Т.е., как видим, удалены функции из public api, но soname не изменился. хуже 
того, обьявления этих функций все еще есть в avcodec.h.
Из-за этого становятся нерабочими все программы, которые используют ffmpeg. 
Пересборка, конечно, помогает, но...

Пересобираем без swscaler, становится несколько лучше, но все же:

Подскажите, что мне с этим делать?

Апстрим невменяем, если что.
