Html 如何在视频对象标签中设置缩略图？

我正在使用对象标记在浏览器中播放视频

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="fitvid473410"><param name="movie" value="http://demo.assetbank.co.uk/assetbank-standard/tools/jwplayer/player.swf">
<param name="flashvars" value="file=http://win-hk4iec2ge2r:1111/sites/KL007/Lists/KLDocumentLibrary/other.mp4&amp;autostart=false&amp;image=?previewFileLocation?&amp;backcolor=000000&amp;frontcolor=EEEEEE&amp;lightcolor=FFFFFF&amp;screencolor=000000&amp;autostart=false&amp;stretching=exactfit&amp;provider=video&amp;duration?">
<param name="allowfullscreen" value="true">
<param name="scale" value="default">
<param name="wmode" value="transparent">
<param name="allowscriptaccess" value="always">
<embed id="player1" width="300px" height="500px" type="application/x-shockwave-flash" src="http://demo.assetbank.co.uk/assetbank-standard/tools/jwplayer/player.swf" flashvars="file=http://win-hk4iec2ge2r:1111/sites/KL007/Lists/KLDocumentLibrary/other.mp4&amp;autostart=false&amp;image=?previewFileLocation?&amp;backcolor=000000&amp;frontcolor=EEEEEE&amp;lightcolor=FFFFFF&amp;screencolor=000000&amp;autostart=false&amp;stretching=exactfit&amp;provider=video&amp;duration?" allowfullscreen="true" allowscriptaccess="always">
</object>

您能告诉我，在上面的对象标记中，我可以在哪里设置预览图像（我有一个图像url）？

您可以按如下方式操作：

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="fitvid473410"><param name="movie" value="http://demo.assetbank.co.uk/assetbank-standard/tools/jwplayer/player.swf">
    <param name="flashvars" value="file=http://win-hk4iec2ge2r:1111/sites/KL007/Lists/KLDocumentLibrary/other.mp4&amp;autostart=false&amp;image=<image path>?previewFileLocation?&amp;backcolor=000000&amp;frontcolor=EEEEEE&amp;lightcolor=FFFFFF&amp;screencolor=000000&amp;autostart=false&amp;stretching=exactfit&amp;provider=video&amp;duration?">
    <param name="allowfullscreen" value="true">
    <param name="scale" value="default">
    <param name="wmode" value="transparent">
    <param name="allowscriptaccess" value="always">
    <embed id="player1" width="300px" height="500px" type="application/x-shockwave-flash" src="http://demo.assetbank.co.uk/assetbank-standard/tools/jwplayer/player.swf" flashvars="file=http://win-hk4iec2ge2r:1111/sites/KL007/Lists/KLDocumentLibrary/other.mp4&amp;autostart=false&amp;image=?previewFileLocation?&amp;backcolor=000000&amp;frontcolor=EEEEEE&amp;lightcolor=FFFFFF&amp;screencolor=000000&amp;autostart=false&amp;stretching=exactfit&amp;provider=video&amp;duration?" allowfullscreen="true" allowscriptaccess="always">
    </object>

这可能会有所帮助
