jwplayer播放器 手机端用不了啊

用的是kindeditor-4.1.10编辑器，上传视频后，PC端可以显示并播放，手机端播放不了

 <embed id="player" allowscriptaccess="always" allowfullscreen="true" flashvars="file=/pic/flash/20170831/20170831130646_349.mp4" src="/kindeditor-4.1.10/plugins/jwplayer/player.swf" width="770" height="450" quality="high" />

自己用js处理下，判断是移动端就更改为video标签

 <embed id="player" allowscriptaccess="always" allowfullscreen="true" flashvars="file=/pic/flash/20170831/20170831130646_349.mp4" src="/kindeditor-4.1.10/plugins/jwplayer/player.swf" width="770" height="450" quality="high" />
