파이썬 2.7에서 pyffmpeg를 성공적으로 설치하지 못했습니다. 파이썬 2.6 패키지를 찾았지만 제대로 작동하지 않습니다. 그래서 저는 2.7로 둘러 보았습니다. 이 사이트의 다른 사람들로부터 이전 게시물을 보았지만 도움을받지 못했습니다. 누구나이 경험이 있습니까? 궁극적으로 비디오 포맷을 변환하는 wxPython 앱을 개발하고 싶습니다. 내가 궁극적으로 나를 위해 (매우 초보지만 .... 작동) 일 쓴 감사파이썬 2.7에서 ffmpeg 사용하기

pyffmpeg는 인코딩 기능을 제공하지 않습니다. 그래서 내가 avi로 사용자 정의 비디오를 변환하는 wx 앱을 만들 때, 나는 ffmpeg 실행 파일과 통신하기 위해 서브 프로세스 모듈을 사용했다. 똑똑한 솔루션이 아니라 작동합니다. 그렇지 않으면 작업을 수행 할 수있는 [libVLC] (http://wiki.videolan.org/LibVLC)에 대한 파이썬 바인딩이 있습니다. – otterb
oops. libVLC는 디코딩에만 국한된 것으로 보입니다. – otterb
@otterb - 서브 프로세스 모듈을 사용하지 않았지만 유사한 접근법을 취했습니다. os.system (...)을 사용하여 ffmpeg를 중지하고 시작한 다음 명령을 명령 줄에 전달했습니다. "똑똑한 해결책은 아니지만 작동합니다 ...." – suffa
