如何正确停止ffmpeg屏幕录制? [英] How can i stop ffmpeg screen recording correctly?

问题描述

我正在记录屏幕并将其保存到* .mkv容器中(我不确定这是否是我真正需要的，我之所以选择它是因为在文件开始处使用了matadata，并希望该文件可以正常运行如果simething会出错)，请使用以下命令:

I am recording my screen and saving it to a *.mkv container (I am not sure it is what i really need, i have chosen it because a matadata in start of the file, and had hoped the file will be OK if simething will be wrong) using command:

ffmpeg -f x11grab -r 7 -s 1920x1080 -i :0.0 -vcodec png -f segment -segment_time 20 Video_%02d.mkv

我有问题:使用硬件按钮:)关闭我的电脑时，我的视频文件段大小为0，我不知道为什么会发生这种情况.

I have problem: When a shut down my pc, using the hardware button :), i have 0 size video file segment, i don't know why it happens.

推荐答案

在运行命令时应按Q.这是退出ffmpeg的设计方法.

You should press Q while running the command. This is the designed way of quitting ffmpeg.

或者，如果您无法访问ffmpeg进程的标准输入，则可以将其终止.

Or you can kill the ffmpeg process with SIGINT, if you cannot access its standard input.
