Three things in order to run video flv:

1. Create blank new flash file. Open library, add "New video" object to library, then add it to stage with the instance name "my_video".
2. Create new layer with a multy-line input text field w/ a border that lies above the "blank video object". The instance name of the txt object must be: "status_txt"
3. Add script written below to the first frame of the flash movie. Save flash movie with the name you want + put following FLV file (videoFile.flv) in the same directory where you're going to execute SWF for streaming.
