解决方案

我是测试中的文件实际上是破坏。但是，如果任何人面临这个问题，设置-probesize和-analyzeduration 100到10,000,000例如可能的帮助。

I am getting an error while executing the command ffmpeg -i /path/to/video.mp4 :

    Consider increasing the value for the 'analyzeduration' and 'probesize' options
    /path/to/video.mp4: could not find codec parameters

The files I was testing were in fact damaged. But if anyone faces this problem, setting -probesize and -analyzeduration to 100 and 10000000 for example might help.
