AS3 class NetstreamInfo returns invalid values

I wrote a little swf Container which should upload a video file and play it. I followed the official Adobe documentation and the video played smoothly.

Subsequently, I added a few ExternalInterface API callbacks to pause, play, and resume the video, they all work fine. There is only one very unpleasant problem: I can not get information about the current state of the video. Neither a call through the javascript function, nor an internal call in the swf file provide the correct information. I worked a little on this and did not find any information about this problem.

Here's the source code for the swf file and an example html for embedding it:

HTML

<object id="ie-video" width="1280" height="720" type="application/x-shockwave-flash" data="flash_container.swf">
    <param name="movie" value="flash_container.swf" />
    <param name="wmode" value="opaque" />
    <param name="flashvars" value="vid_name=video&amp;objWidth=1280&amp;objHeight=720" />
    <param name="AllowScriptAccess" value="always">
</object>

element.getCurrentTime();
