我找到了这个教程:
http://stream0.org/2008/02/howto-extract-images-from-a-vi.html
它告诉我如何从命令行使用ffmpegX从视频中提取帧(至少这是我所理解的)。
我在我要提取的.MOV文件的目录中cd并在Mac OS终端(!)中运行:
ffmpeg -i mymov.MOV -r 25 -f image2 images%05d.png和
ffmpegX -i mymov.MOV -r 25 -f image2 images%05d.png但是我得到了:
-bash:ffmpegX:找不到命令
这一切都在Mac上。
我所做错的任何想法都会很棒。
非常感谢。
I found this tutorial:
http://stream0.org/2008/02/howto-extract-images-from-a-vi.html
Where it tells me how to extract frames from a video with ffmpegX from the commandline (at least that is what I understood).
I cd in the directory where the .MOV files is I want to extract and ran in the Mac OS Terminal(!):
ffmpeg -i mymov.MOV -r 25 -f image2 images%05d.pngand
ffmpegX -i mymov.MOV -r 25 -f image2 images%05d.pngBut on both I get:
-bash: ffmpegX: command not found
All this on a Mac.
Any ideas what I am doing wrong would be great.
Thanks a lot.
