ruby-on-rails – FFMPEG说文件不存在,但它存在

2019年7月21日 226次阅读

我通过streamio-FFMPEG Rails gem-
https://github.com/streamio/streamio-ffmpeg使用FFMPEG

出于某种原因,当试图对视频文件进行转码(确实存在)时,FFMPEG表示该文件不存在.

这是Rails控制台的一些输出,证明了我的头痛：

1.9.3p125 :001 > File.exist?("/Applications/MAMP/htdocs/video-app/public/uploads/tmp/20131208-1416-1234-0984/videotest.mp4")
 => true

任何帮助,将不胜感激.

最佳答案 它看起来无法找到ffmpeg二进制文件本身,而不是您指定的文件.在调用构造函数之前,尝试设置FFMPEG的完整路径：

FFMPEG.ffmpeg_binary = '/usr/local/bin/ffmpeg'
