iPhone 游戏背景是视频还是动画图像？
我需要为整个 iPhone 屏幕创建一个非常短的背景动画。我想弄清楚是否应该使用视频或为一系列 PNG 文件制作动画。 有谁知道使用视频作为应用程序背景而不是在 UIImageView 中动画的一系列 PNG 文件的优势？我听说视频可以压缩到非常小的尺寸，并且比动画 PNG 看起来更好。 提前致谢。
I need to create a very short background animation for the entire iPhone screen. I am trying to figure out whether I should use a video or animate a series of PNG files.
Does anybody know the advantage of using video as an app background instead of the series of PNG files being animated inside UIImageView? I heard that video can be compressed to really small size and will look better that animated PNGs.
Thanks in advance.

我真的不认为使用视频而不是一系列 PNG 是一个好主意。如果你节省了几千字节的话，你的生活就会变得更加复杂。
当然，这在很大程度上取决于您想要制作动画的具体内容以及您试图节省空间的位置。例如，如果您尝试在二进制文件中节省内存，并且将 PNG（已经很好压缩的格式）放在动态解压缩的 zip 中，则 zip 算法将排除大多数相似之处。如果您试图在游戏过程中节省内存空间（而不是在二进制文件中），那么这不算数。然而，加载视频库二进制文件很可能会比少数 PNG 更混乱你的内存。
这个 项目 使用 JPG 完成工作，它应该是用 PNG 很容易改变它；）
I really don't think using a video rather than a series of PNG is a good idea. You'll make your life more complicated for a few kilobytes saved, if you even save any.
It is of course highly dependent on what exactly you are trying to animate, and where you try to save space. For example, if you try to save memory in the binary and if you have your PNGs (already well compressed format) in a zip that you unzip on the fly, most similarities will be factored out by the zip algorithm. If you're trying to save space in memory during the game itself (not in the binary), then this doesn't count. However, loading up the video library binaries has a serious chance to clutter your memory more than the few PNGs will.
This project does the job with JPG, it should be very easy to change that with PNG ;)
