[Xerte] Re: Interesting Problem with Swfs

OK, that plays fine for me via Xerte desktop - shall I replace all the files on our XOT with those in the zip?

(I'll backup first ofc)

Let's make sure we're playing with the same files.

Download this: http://www.nottingham.ac.uk/~cczjrt/menuBug.zip

I can't reproduce the menu issue now, and it *appears* to work as expected...

This is my Nottingham.rlt:

if (engine[ytID] != undefined){
  engine[ytID].stopVideo();
  //engine[ytID].destroy();
  engine[ytID].removeMovieClip());
  delete engine[ytID];

Still results in the swf problem (although youtube players are stopping on page move)

Also tried it with ID = 6 but no different

Just comment that line out and let's see if by avoiding the call to destroy we can keep everything else working. It looks OK here, but that function call is in there for a reason, and there are some revealing comments (!) in the youtubeComponent.fla about the need for that function call that contain the three letters W, T and F, so it's not the first time I've been here.

At least for now, I have narration hiding / showing as it should, the movie on the menu page initialising properly (i.e. being killed properly from the last time) and the youtube component destroying itself when I avoid destroy(), which, I think, were the issues...

NO I want to sort it because this is fairly fundamental to how xerte works on the inside, and it's only the youtube component that screws things up.

As it stands now, with the line to destroy commented out, I can make both things work.

The next line, setting it to some number, ought to make sure it's gone and wipe out the references to it.

Try it?

Seem to be yes!

I wonder if there is an better way to do this? Would it be easier to have an optional property on  the menu page that would accept a video (e.g. youtube embed using the same basic principal of the current youtube rlm)?

Just a thought...appreciate this is asking quite a bit...

But is everything else? Narration is my concern. If you can try as many combinations of the narration settings on previous pages, next pages, all pages and try navigating to them  forwards, backwards, sideways, that would help put my mind at rest.

Need to make sure that narration shows when it should show and is erased when it should erase, and after being erased is able to be re-drawn.

You can download the project zip directly from here: http://elearning.net.marjon.ac.uk/stuff/SWFprob.zip

Just open the youtube page, then navigate back to the main menu to see the swf problem.

Does template.rlt need to replace Nottingham.rlt?

If yes - done that and overwrote menu model, restarted IIS, cleared cache, made a new Xerte and the problem still persists

Hmm. Just tried a new LO just in case and problem still persists. Are you using the new youtube.rlm that you sent last week?

I've exported a test as a zip which you can find here: http://elearning.net.marjon.ac.uk/stuff/testvid.zip - perhaps some of the other files im using are out of date?

When I tried to upgrade the whole of our XOT site, it broke our installation, so reverted and just did the models etc and the main engine stuff.

Don't think it's the player controls - created the attached swf - a simple shape tween.

Exactly the same happens when jumping directly back from the YT page:

Try it with a more basic swf: I have a feeling that playback controller in your swf might be causing problems. Try a simple animation and see if it works. It works for me... so I think it is something in your swf not playing nice.

I've been experimenting with toolkits, and a learning object with 'menu with page controls' navigation enabled. On my menu page, I've added the optional menu page image property. Rather than just use a boring image, I've attempted to insert a swf - which itself plays a FLV video (from our streaming server) and also has its own player controls (linked from the Xerte media files).

You can view the LO here: http://elearning.net.marjon.ac.uk/rlo/play.php?template_id=334

Hopefully you'll see that the swf video loads fine, and can be controlled by the user with the control buttons. Everything fine so far...

[cid:image003.jpg at 01CC2C0C.96B75A10]

Now click the menu button for 'Inserting Page Breaks: Part 1' - which loads the modified youtube page type that Julian worked on last week. This works fine also.

However, now for the interesting behaviour...while on the youtube page - use the contents button from the top menu to return to the main menu, and you should see that Xerte loads several instances of my original swf video and breaks:

[cid:image004.jpg at 01CC2C0C.96B75A10]

This doesn't happen if you use the previous/next buttons - it only seems to replicate when directly jumping between the YT page and main menu.

Any ideas how I could stop this? Let me know if you want me to share the swf and LO.
