Sivakatirswami,

I tested the stack here but modified the script so that the gonext would:
on gonext tVar
------ snip
go card tVar
end gonext

and modified the "set next slide point to include the card number of the next card etc. This let me put lots and lots of 3543, gonext 4 ,etc. This showed lots of transitions between cards and was very fast too.

Anyway, I notice that the player object itself seems to hang around a 1/4 of an inch in and then does eventually start moving. I am looking at the actual slider of the player object and it does hang and then jump ahead to catch up, if you will, and then the slides start to play again. It appears that this is a bug or message update of the object and not your script. It is not on slide so and so that this happens but rather at some point in time the player object does not update.

By the way it happens again later in the song at about three quarters of the way where it hangs again. The music still plays but the player object is not updated and the "callbacks" must be using the actual player object's state even though the song is much further along.


Weird, I would bugzilla this one for sure.

[[and all quicktime callback wizards.. help!]]

OK, its up here:

go url "http://www.himalayanacademy.com/runrev/stacks/yogaswami.rev";

All the set up controls are in a background group that is offset to the right. To see them just resize the stack window to very wide...

I just added an audio file picker and also a button up for pointing the player to our webserver (docRoot is hirdwired in that script...to http://www.himalayanacademy.com, change it to your own web server)
=========

but, I'm still having problems with QT player callback implementation....even if the file reference is a local .mp3 file ....or streamed from our web server. Either way it's broken here.

Klaus: are you *sure* all 11 of the callback messages were sent- implemented on your box? They are not here.. did you see all 11 slide transitions?

Here's what should happen: there is a title card and 10 card with images. After clicking "Begin" you should go thru all 11 cards and then arrive back at the title card... (Music continues for a long time after that, just stop it with the controller, or from msg box "stop player "music")

I set up 11 call backs at about 3000 1/600th's of a second intervals. each one simply issues the message "goNext" There is at most a 5 second interval between slides, most transitions are in less time. So going thru all 11 slides should take about a minute or two a the most, if it stops on one slide for more than 6 seconds before you get back to the title, you know callback messaging just died....

What actually happens: I click begin... all this does is "start player "music" the slide show should be driven by callbacks after that... and, whether the file is local or being streamed from the internet... the callbacks "hang"-- in the IDE they hang after about 4th or 6th callback message is sent, none after that. If I run it from a stand alone player, I may get as far as the 8th callback "goNext" implemented. It's random... in both cases, the music continues, but no more callbacks messages are sent.

(Klaus, you were right, it doesn't need to be in the player script at all :-)... docs should say "msg is sent to the player, if not trapped there then passed up the msg hierarchy")

stack script

on goNext
  visual effect dissolve very fast
  go next card
end goNext

the callbacks of player "music"

3508,goNext
8286,goNext
11627,goNext
14132,goNext
16532,goNext
19119,goNext # it stops here! ouch
21160,goNext # all the following do not happen,
23527,goNext # the player just goes right thru these
25975,goNext # interval points and nothing happens
27750,goNext
29695,goNext


Hmm. I really hope this is not a bug... but with just a 4 line script and two value callback parameters, there is not a lot a of wiggle room to fix anything. I just had big dreams of stuff I could do with callbacks all turn pale blue.

Is there anyone lurking who works a lot with callbacks that can help us?

Sivakatirswami and Klaus,

Do you have the sample stack online? I'd like to check it out. Seems great so far.
