从一组 jpeg 图像创建动画 gif [英] Create animated gif from a set of jpeg images

问题描述

我需要可以在 Windows 7 上编写脚本的内容.此图像将用于横幅.

I need something that can be scripted on windows 7. This image will be used in banners.

推荐答案

您可以使用 ffmpeg

首先将图像转换为视频:

First convert the images to a video:

ffmpeg -f image2 -i image%d.jpg video.avi

(这会将当前目录中的图像(名为 image1.jpg、image2.jpg...)转换为名为 video.avi 的视频文件.

(This will convert the images from the current directory (named image1.jpg, image2.jpg...) to a video file named video.avi.)

然后将 avi 转换为 gif:

Then convert the avi to a gif:

ffmpeg -i video.avi -pix_fmt rgb24 -loop_output 0 out.gif

_{您可以在此处获取 ffmpeg 的 windows 二进制文件.}

您也可以使用 mplayer 做类似的事情.请参阅来自多个输入图像文件的编码.

You can also do a similar thing with mplayer. See Encoding from multiple input image files.

我认为命令行应该是这样的:

I think the command line would be something like:

mplayer mf://*.jpg -mf w=800:h=600:type=jpg -vf scale=160:120 -vo gif89a:fps=3:output=out.gif

(其中 800 & 600 是您的源宽度和高度，160 & 120 是目标宽度，height.out.gif 是您的目标文件名)

(Where 800 & 600 are your source width and height and 160 & 120 are the target width and height.out.gif is your target file name)

我刚刚测试了这两个，它们都可以正常工作.但是我从 mplayer 得到了更好的结果，因为我能够指定分辨率和帧率.您的里程可能会有所不同，我相信您可以找到更多关于 ffmpeg 的选项.

I've just tested both of these and they both work fine. However I got much better results from mplayer as I was able to specify the resolution and framerate. Your milage may vary and I'm sure you could find more options for ffmpeg if you looked.
