Re: OSMF having playing problems when used in OSGi context

Hi Ramazan,

This project does not officially support OSMF.  The Flex project uses OSMF as a 
dependency, and Royale may as well someday, but there aren't any members of the 
Flex or Royale project who know the code and Flex and Royale are not the home 
for the OSMF source code.


Some folks on the Flex and Royale mailing lists may have experience using OSMF, 
but I'm not one of them.  Your email was hard to read, can you make it easier 
to see the difference in the logs?  It isn't clear to me if you are somehow 
using AIR as the runtime in an OSGI bundle that is part of some other large 
application or what.  Anytime you wrap a runtime in a bundle there may be 
restrictions on what that bundle can access.

HTH,
-Alex

    I've created an OSMF plugin which fetch videos from youtube and then play 
them when the url is received.
    When I test my plugin in an Adobe AIR Desktop project the video plays 
without a problem.
    The code for the test app is the folowing:

    and the video appears well :

    here is my problem, when I'm trying to use my OSMF plugin run the plugin in 
a dynamic app packaged as an OSGi bundle with an activator my plugin fails to 
play the video.
     
    the log output is this:
