Is the codec supported? And what has be tried to resolve?
Can you pls tell me how to check if the codec is supported?
My firefox version is 39 & silverlight player is 5.1 Also when I play wmv video, the audio is fine & slider also moves but the screen is black. If the same wmv video is streamed through an external window media server then it plays fine
poojha sure I can, these are the lists of supported codecs: Silverlight (black screen): https://msdn.microsoft.com/en-us/libr.../cc189080%28v=vs.95%29.aspx
Flash (works) - https://helpx.adobe.com/flash/kb/supported-codecs-flash-player.html if installed to tell if its playing you know to look for the plugin icon in the url bar: http://camendesign.com/code/video_for.../test.html
Quicktime (works) - https://support.apple.com/en-us/HT201290 -test page: http://camendesign.com/code/video_for.../test_qt.html
If you right click on the webpage and select "Page Info" the window that opens up will have a Media tab. I believe the video file type will be indicated by the file extension. However even further you can check the headers of the media requests in the console, but the first should be simpler.
I will post back as other troubleshooting steps include:

With what content-type does the server sends these files?
What code are you using to play the files?
Another thought, perhaps if its not a codec issue, the console log may have an error, can you check in the set up when you play the video in the sliverlight player?
