Seems like your local libav is not the right version. If you are on a mac, try re-installing ffmpeg with brew.

libavresample was initially merged into ffmpeg to be a drop-in replacement for libav, but was never maintained by ffmpeg itself in favor of their own libswresample. According to upstream, libswresample can do everything libavresample can do and more, plus libavresample has been entirely deprecated at the end of last year.
