推荐答案

好吧，我会直接使用ffmpeg。你也可以用ImageMagick来做;然而，文档声明你需要安装ffmpeg，为什么要让中间人？

Well I would jump stright into using ffmpeg. You can also do it using ImageMagick; however the docs state you need ffmpeg installed, so why have the middleman?

我没有测试过这个，公平警告。

I haven't tested this, fair warning.

/*   cmd                 img series    codec       bitrate framerate  optional -s WidthxHeight and output filename */
exec(ffmpeg -f image2 -i image%d.jpg -vcodec mpeg4 -b 800k -r 12 video.avi);
/* For Mpeg4 *

/*For FLV */
exec(ffmpeg -f image2 -i image%d.jpg -vcodec flv -b 800k -r 12 video.flv);

如果你想使用过时的mpeg2或mpeg1格式，你也可以这样做。
我建议通过ssh连接并测试这些命令，希望你安装了ffmpeg。
a ffmpeg -formats 将显示支持的格式：

If you want to use the outdated mpeg2 or mpeg1 formats you can do that as well. I would suggest connecting via ssh and testing these commands, and hopefully you have ffmpeg installed. a ffmpeg -formats will show you which formats are supported:
