我有一个MKV文件,其中包含多个音轨,每种音轨都有一种语言。我想添加一个按钮来更改语言。有人可以帮我吗?
HTML:
<video autoplay id="videoid" controls controlsList="nodownload" disablePictureInPicture poster="<?php echo base_url();?>assets/user/images/loading.jpg">
<source src="<?php echo base_url(); ?>uploads/images_or_videos/<?php echo $content->image_or_video; ?>" type="video/webm">
</video>
Javascript:
$(document).ready(function(){
var aud = document.getElementById("videoid");
aud.onplaying = function() {
alert(aud.audioTracks.length);
}
});
答案 0 :(得分:0)
var video = document.getElementById("video");
// mute all
for (var i = 0; i < video.audioTracks.length; i += 1) {
video.audioTracks[i].enabled = false;
}
// show languages and labels
for (var i = 0; i < video.audioTracks.length; i += 1) {
console.log(video.audioTracks[i].language)
console.log(video.audioTracks[i].label)
}
// enable one
video.audioTracks[2].enabled = true;
