Thank you TullioFilippi,
I’ve found a solution for the problem.
Before, we were using this code (generated by S3 Video Plugin):
<object width="640" height="380" id="s3EmbedVideo" name="s3EmbedVideo" data="https://releases.flowplayer.org/swf/flowplayer-3.2.15.swf" type="application/x-shockwave-flash">
<param name="allowfullscreen" value="true">
<param name="allowscriptaccess" value="always">
<param name="quality" value="high">
<param name="bgcolor" value="#000000">
<param name="flashvars"
value='config={
"clip":{"autoBuffering":"none","autoPlay":false,"bufferLength":5},
"playlist":[
{"url":"https://xxxxxx.s3.amazonaws.com/xxxxxxxxxxx.jpg","scaling":"fit","autoPlay":true,"autoBuffering":"none","bufferLength":5},
{"url":"https://xxxxxx.s3.amazonaws.com/xxxxxxxxxxx.flv","title":"The film title","autoPlay":false,"autoBuffering":"none","bufferLength":5}
],
"playerId":"player"
}'>
</object>
But now, we use this:
<object id="s3EmbedVideo" name="s3EmbedVideo" width="300" height="200"
data="https://releases.flowplayer.org/swf/flowplayer-3.2.16.swf"
type="application/x-shockwave-flash">
<param name="movie" value="https://releases.flowplayer.org/swf/flowplayer-3.2.16.swf" />
<param name="allowfullscreen" value="true" />
<param name="allowscriptaccess" value="always">
<param name="quality" value="high">
<param name="bgcolor" value="#000000">
<param name="flashvars"
value='config={
"clip":{"autoBuffering":"none","autoPlay":false,"bufferLength":5},
"playlist":[
{"url":"https://xxxxxxxx.s3.amazonaws.com/xxxxxxxx.jpg","scaling":"scale","autoPlay":true,"autoBuffering":"none","bufferLength":5},
{"url":"https://xxxxxxxxx.s3.amazonaws.com/xxxxxxxx.flv","title":"The film title","autoPlay":false,"autoBuffering":"none","bufferLength":5}
],
"playerId":"player"}'/>
</object>
and it’s ok in IE8, IE9, Firefox, Chrome, Opera
?We are happy!
