I’m trying to play a video via RTSP using Adobe Air, I have the permissions:
<action>access_internet</action>
<action>set_audio_volume</action>
<action>access_shared</action>
<action>play_audio</action>
but when I play (), it does nothing.
It’s possible to do RTSP Streaming on Playbook? If not, it’s possible any other kind of videostreaming? webworks? html5 video tag?
The native Youtube App preinstaled do streaming video.
Thanks in advance
here the sample code

It seems that RTSP wasnt supported in 6/2011 (a year ago). From the release notes on the updates of the NDK. The native Youtube App may not be using RSTP for streaming (there are other ways to stream video). Check out this link for more information.
But on the Webworks side, Yes. The Html5 video tag is fully implemented. You can find out more information here: https://bdsc.webapps.blackberry.com/html5/apis/HTMLVideoElement.html it will use the built in video player. Just note that this will not work on BB10.
Update: The HTML5 video tag is now also supported on the BB10 platform.
