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.此图像将用于横幅广告.

解决方案

您可以使用 ffmpeg

首先将图像转换为视频:

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

(这会将图像从当前目录(名为image1.jpg，image2.jpg ...)转换为名为video.avi的视频文件.

然后将avi转换为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.请参见从多个输入图像文件进行编码./p>

我认为命令行类似于:

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

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

---

我都测试了这两个，它们都工作正常.但是，由于可以指定分辨率和帧速率，因此从mplayer获得了更好的结果.您的里程可能会有所不同，如果您查看ffmpeg，我相信您可以找到更多选择.

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

解决方案

You can do this with ffmpeg

First convert the images to a video:

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

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

Then convert the avi to a gif:

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

_{You can get windows binaries for ffmpeg here.}

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

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

(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)

---

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.
