<h4>关于 SubmitTranscodeJobs</h4>
<p>转码模板可以复用，也可以覆盖参数</p>
<p>水印模板可以复用，但是只能和绑定的转码模板一起</p>
<p>图片是上传到 oss，返回的 fileUrl 可以用于覆盖参数</p>
<hr />
<p>模板 => 固定</p>
<p>水印 => 给个默认点开就看</p>
<p>上传水印 => 存储 oss 的 url 地址，</p>
<p>然后打水印只需要指定 oss 的水印图片，指定位置，根据视频宽高修改占比</p>
<hr />

<h4>关于 userdata 的坑</h4>
<p>UploadMediaByURL 或 CreateUploadVideo 设置的 UserData 在视频的整个生命周期都是生效的 </p>
<p>这意味着，这个 userdata 是没有意义的</p>
<p>并且一个 fileid 永远只能有一个回调 url，没有灵活性</p>
<p>aliserver 和 点开后台也共享不了一个回调URL，这是一个大坑</p>
