SPECX 디코딩을 지원하도록 ffmpeg 컴파일

Question

Speex 디코딩을 지원하기 위해 ffmpeg를 컴파일하려고합니다. 내 쉘 스크립트에서 다음 플래그 --enable-libspeex를 사용하여 speex 디코딩을 활성화했습니다. 나는 또한 this 링크에서 다운로드 된 speex 1.2rc1을 컴파일했습니다. 헤더 파일을 컴파일 한 후이 경로/usr/local/include/speex에서 사용할 수 있습니다. 위의 절차에 따라 ffmpeg가 SPEEX 디코딩을 지원하도록 컴파일 될 때 libspeex를 찾을 수 없다는 오류가 발생합니다. 아무도 도와 줄 수 있습니까?

Answer 1

어느 당신의 gcc가 경로에 /usr/local/lib이없는 /usr/local/include 또는 동적 링커에보고되지 않습니다.

speex를 다시 컴파일하고 --prefix=/usr 옵션을 구성하십시오.
