I’ve been trying to find away to seek to Cue points with-in a streaming .flv and actually have it play from that Cue point forward, instead of showing half a second of video from that cue point and jumping back to the beginning. This happens using the skin controls and buttons in the flash file. It happens weather the cue points are embedded in the video as Navigation points or in the ActionScript. Any help would be appreciated.
Finally got the solution from adobe, I was using the synconized video template provided by Adobe:
http://www.adobe.com/devnet/flash/ar...corppreso.html
It says you can put in a streaming video, change the component setting and it will work...needless to say this was not the case. The change must be made in the ActionScript code that calls the slides and the buttons, I have written up these changes and posted them so nobody has to go through same ordeal I did to make something work the way it is supposed to.
Problem: When a Streaming Video is put into the synced-slide template used to deliver download streaming or CD-Rom based projects, the project will play with the slides in-sync, but when you try to use the buttons or the video skin to advance or retard the slides, the presentation jumps back to the beginning.
The Solution: The problem, as it turns out, is in the code that calls the buttons and the slides that resides on the timeline in the Layer called Actions & Lables on the frame that is labeled “slide1” under the “Actions” tab at the bottom (or the ActionScript)– at the beginning of video / synced-slide portion of the template. The problem lies in the placement of five lines of code that are moved up, those lines of code are as follows:
{
// If the video is currently stopped, then play it
if(!display.playing ){
display.play();
}
In the original code used for the Download Streaming / CD Rom, this portion was lower in the code, beneath the beginning section that looks like this:
// Is this a screens document or not?
var uses_screens:Boolean = false;
stop();
// *************************
// Navigation buttons call this function to trigger a change
// in the video and the view of the content
function seekToCuePoint( cueName ) : Void
{
// Find the cue point in the FLVPlayback component, seek
// to time, and highlight the next button for a quick redraw
var c = display.findCuePoint( cueName );
display.seekSeconds( c.time );
findNextButton( c.name );
}
// *************************
// The natural flow through the video or jumping by seeking
// forward and backward will trigger the following function
function synchVideoToInterace( cueName:String ):Void
{
// If the video is currently stopped, then play it
if(!display.playing ){
display.play();
}
If you wanted to manually change this code with-in a pre-existing Download Streaming / CD Rom presentation, simply cut the code out of it’s location, and paste it higher in the code, beneath the section that follows that you will recognize from the previous section:
// Is this a screens document or not?
var uses_screens:Boolean = false;
stop();
// *************************
// Navigation buttons call this function to trigger a change
// in the video and the view of the content
function seekToCuePoint( cueName ) : Void
If all of that is too confusing, I have copied the two codes in there intirety onto the next four pages of this document, labeled to show which is used for streaming and which is used for Download Streaming / CD Rom presentations, simply copy and paste from this document into the code area specified above, and you should be good to deliver any way that is possible.
For Download Streaming / CD Rom presentations:

var c = display.findCuePoint( cueName );
display.seekSeconds( c.time );
findNextButton( c.name );
}
// *************************
// The natural flow through the video or jumping by seeking
// forward and backward will trigger the following function
function synchVideoToInterace( cueName:String ):Void
{

if( highlight_mc == undefined ){
this.attachMovie("ThumbOutlineSelected","highlight _mc", 100);
