I want to embed some video into my HTML page. 我想将一些视频嵌入到HTML页面中。 As background I want to use big picture. 作为背景，我想使用大图。 And above it I want to insert loop video with (ie) walking man. 在它上面，我想与（即）步行者插入循环视频。

So, can I embed video (without flash and any player controls) in page? 那么，我可以在页面中嵌入视频（没有Flash和任何播放器控件）吗？
Can I decode video with transparent background? 我可以解码具有透明背景的视频吗？ Is there any codecs which support transparent background (alpha-channel)? 是否有任何支持透明背景（alpha通道）的编解码器？

Now I see this solutions: 现在，我看到以下解决方案：

Making flash (that I don't want to use) 制作闪光灯（我不想使用）
Create gif animation (and it will be big file size and quite bad quality) 创建gif动画（文件大小很大且质量很差）

1 个解决方案

I don't believe that's possible with anything beyond GIF (over sized and would have a horrible border between opaque and transparent), MNG (not widely supported), and scripted SVG. 我认为，除了GIF（尺寸过大，并且在不透明和透明之间会有可怕的边界），MNG（不受广泛支持）和脚本化SVG之外，这是不可能的。

Have you thought about figuring out where in the background this video would appear and putting THAT section of the background into the video as a static background behind the man walking? 您是否考虑过找出该视频在背景中出现的位置，并将该背景的那一部分作为视频显示在走着的人后面的静态背景？
