MainConcept AAC Encoding Integration RRS feed

  • Question

  •  Hi There,

     Can i Integrate Silverlight 3 with MainConcept AAC encoding?

    Now we have Windows Media Encoder as a Feed

    It's possible to use MainConcept AAC encoding as the Feed to a Silverlight 3 Streamer?


     Best Regards,
