我正在创建一个需要流式传输视频的网站。内容创建者将 .mov 文件上传到服务器。上传后，我使用 FFMPEG、.mp4、.webm 和 .ogg 转换为以下格式。
我现在正试图允许从多个浏览器和手持设备查看视频。代码如下：
<head>
<script>
var video = document.getElementById('video');
video.addEventListener('click',function(){
video.play();
},false);
</script>
<script type="text/javascript" src="jwplayer.js"></script>
</head>
<body>
<video id="video" autobuffer height="240" width="360" controls>
<source src="output.mp4">
<source src="output.ogv" type="video/ogg">
<source src="output.webm" type="video/webm">
</video>
<script type="text/javascript">
jwplayer("video").setup({
modes: [
{ type: 'html5' },
{ type: 'flash', src: 'player.swf' }
]
});
</script>
</body>
该视频适用于所有浏览器。但是，它拒绝在 Android 上播放。当我单击播放按钮时，它显示为仅加载。
我正在测试 4.0.3。
FFMPEG 转换代码：
网站
exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.webm", $command_output, $result);
ogg
exec("ffmpeg -y -i file.mov -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b 345k -s 640x360 output.ogv", $command_output, $result);
flv
exec("ffmpeg -y -i file.mov -ar 44100 -ab 96 -f flv output.flv", $command_output, $result);
对于 MP4：
sudo ffmpeg -i file.mov -s 320x240 -c:v libx264 -pix_fmt yuv420p -profile:v baseline -preset slow -acodec aac -strict experimental -ac 2 -r 15 -ab 44100 -aspect 16:9 output.mp4
