Our company is doing one project there the requirement is
that the client will upload the wmv file to the server and the
flash program has to read the files as per user actions and finally
to play the wmv video dynamically.
Playing flv seems to be easy but I dont know how to import
video wmv on runtime and play.
Flash can only take FLV, with the exception of the new Flash
Player accepting H.264 encoded video. In your case, it's not
possible to load a wmv file into the FLVPlayback component, or
using a Video object. You'll need to invest in a server side video
converter, like Flix Pro. When a user uploads a video, it will
convert the video to FLV for you.
