推荐答案

出现错误：

[libx264 @ 0x8d6220] broken ffmpeg default settings detected
[libx264 @ 0x8d6220] use an encoding preset (e.g. -vpre medium)
[libx264 @ 0x8d6220] preset usage: -vpre <speed> -vpre <profile>

您可能需要命令-vpre perset（例如-vpre fast）。
也许你libx264太老了
在使用2014年内置的ffmpeg时，我遇到相同的错误。

you may need the command -vpre perset (e.g. -vpre fast). maybe you libx264 is too old. I meet the same error while using a ffmpeg built in 2014.
