Videoplayer plugin did not work with an RTMP Stream

Hi,
I run an Wowza Stream Server on my local computer.
And set a live application
The Stream url: rtmp://192.168.*.*:1935/live1/mp4:live1_source

<plugin name="video"
url.flash="%SWFPATH%/plugins/videoplayer.swf"
url.html5="%SWFPATH%/plugins/videoplayer.js"
videourl="rtmp://192.168.2*.*:1935/live1/mp4:live1_source"

pausedonstart="true"
loop="true"
enabled="true"
zorder="0"
align="center" ox="0" oy="0"
width.no-panovideosupport="100%"
height.no-panovideosupport="prop"

onloaded="videointerface_setup_interface(get(name)); setup_video_controls();"
onvideoready="videointerface_videoready();"
/>

<!-- the panoramic video image -->
<!-- devices="panovideosupport" -->
<image>
<sphere url="plugin:video" />
</image>
With the setting above, I just got a black screen.
Then I check the error info by o key, no any error info.
Krpano Version: 1.19.3
Flash player Version: 20.0.0.286

Do you have any ideas about the issue?
Thanks and regards.

I use the basic xml syntax of pano video in the video.xml.
And browser it in chrome, it worked.

The setting is:

<plugin name="video"
url.flash="%SWFPATH%/plugins/videoplayer.swf"
url.html5="%SWFPATH%/plugins/videoplayer.js"
videourl="rtmp://192.168.251.145:1935/live/test"
pausedonstart="false"
loop="false"
volume="1.0"
onvideoready=""
onvideoplay=""
onvideopaused=""
onvideocomplete=""
onerror=""
/>

<image>
<sphere url="plugin:video" />
</image>

Compare with the video.xml in videointerface example. I found if the pausedonstart set true, you will get a black screen.
