The final function, updateStatus(), gets called by the SWF file whenever the video_ns
NetStream object’s
onStatus event handler is triggered. This HTML code also defines a
form that has a combo box of videos that the user can choose from. Whenever the user
selects a video and clicks the play button, the
callFlashPlayVideo() JavaScript function
is called, which then calls the
playVideo() function within the SWF file. This function
passes the URL of the SWF file to load into the video instance. As the video plays back
and the NetStream object’s status changes, the contents of the HTML text area on the
Stage are updated.
4. Save your changes to the HTML document, and then upload both the HTML and SWF
files to a website.
5. Open the remote video.html document from the website, select a video from the combo
box, and click the play button.
Flash plays the selected FLV file and updates the contents of the videoStatus text area
within the HTML document.
