How to set the keyframe interval to 5 seconds using FFmpeg?

推荐答案

您需要重新编码.将x264的keyint参数设置为5 * fps，并禁用Scenecut.例如，如果您的fps为24:

You'll need to reencode. Set x264's keyint parameter to 5*fps and disable scenecut. If your fps is 24 for example :

ffmpeg -i <input> -vcodec libx264 -x264-params keyint=120:scenecut=0 -acodec copy out.mp4

这显然不是最佳的质量，但可以满足您的需求.

This is obviously not optimal for quality but it'll match your demand.

根据叹为观止的建议，进行了编辑，将 no-scenecut 更改为 scenecut = 0 .

Edited to change no-scenecut to scenecut=0, as per sigh-boy suggestion.
