推荐答案

调整 -probesize 和/或 -analyzeduration.

我正在测试的文件实际上已损坏.但是如果有人遇到这个问题，例如将 -probesize 和 -analyzeduration 设置为 100 和 10000000 可能会有所帮助.

Adjust -probesize and/or -analyzeduration.

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.

我的解决方案是

ffmpeg -analyzeduration 2147483647 -probesize 2147483647 -i /path/to/video.mp4 

2147483647 是 max_int

2147483647 is max_int
