video 元素支持三种视频格式
带有 Theora 视频编码和 Vorbis 音频编码的 Ogg 文件 | No | 3.5+ | 10.5+ | 5.0+ | No |
带有 H.264 视频编码和 AAC 音频编码的 MPEG 4 文件 | 9.0+ | No | No | 5.0+ | 3.0+ |
带有 VP8 视频编码和 Vorbis 音频编码的 WebM 文件 | No | 4.0+ | 10.6+ | 6.0+ | No |
1、设置一个ogg格式的文件
执行如下:
当浏览器不支持ogg格式时则显示“您的浏览器不支持 video 标签。”
2、设置多种格式
执行如下:
如上图为视频设置一个默认图片。也可以添加其他属性。
controls/controls="controls" 显示播放按钮
autoplay/autoplay="autoplay" 立即播放
loop/loop="loop" 循环播放
muted/muted="muted" 静音
preload/preload="preload" 加载视频d
poster="路径" 显示默认图片
3、自定义播放暂停及大小(Video + DOM)
将javascript写在html的下方
function playPause()
{
i f (myVideo.paused)
myVideo.play(); //播放
else
myVideo.pause(); //暂停
}
function makeNormal()
{
myVideo.width=420; //自定义宽度,高度自适应
}
执行如下:
大多数浏览器支持的视频方法、属性和事件(日后在做理解)
play() | currentSrc | play |
pause() | currentTime | pause |
load() | videoWidth立即执行--视频元素前执行 | progress |
canPlayType() | videoHeight立即执行--视频元素前执行 | error |
duration | timeupdate | |
ended | ended | |
error | abort | |
paused | empty | |
muted | emptied | |
seeking | waiting | |
