Digital Workshop

I open an MP3 sound file in script (not in a video). Play it for a while, then use Get Position and Stop. to save the stop position to a variable...then simply use SetPosition(variable) and Play to restart at the saved position.

I find that the first time it works OK, but then on subsequent gets and sets, it doesn't work, because it creates an offset in the GetPosition (difficult to explain), It seems to add the last GetPosition to the place where it starts.
I can demonstrate by having a ticker continuously monitor the file position by adding a GetPosition to the ticker. I have a 'calibrated' MP3 which is roughly counting in seconds. If I start the file and do nothing, the file and ticker display are synchronised, but if I do a few GetPosition and Set Position, the ticker and file get completely out of sync.
I have used this before in a talking book, and I am certain it worked OK then???, but now when I open that publication, it shows the same problem.
I tried it in V5.5...still the same.
I have reset the registry re-installed etc. I suffered a corrupt page in the publication, but I have completely created a new publication.

I would rather if some kind soul could do a very quick test when they have time ..rather than me posting an imp to try. I am convinced it's either something stupid I'm doing ....perhaps misunderstanding the function of the scripts...or a problem with my setup or imp??

This strangeness is accumulative! And your not mad - the program is. I had this very problem last week. In the end I had to carefully monitor a debug window that was tracking the GetPosition to ensure I wasn't going crazy.

Two things that might help you;

1. Use the video object for you MP3 and pause and play rather than stop, this way, you don't have to use the scripting at all.

2. Try the seek command rather than SetPosition.

Thanks Mack!!!...this really was doing my head in!!! I could see what was happening, but couldn't find a cure- I even tried to compensate for the accumulated error, but my first attempts didn't work, but now I know it's not something stupid I'm doing, I might spend some more time on it. There is a reason why I want to use the sound objects rather than video.

I'll look at the seek commands.

I am convinced the talking book I created about a year ago functioned correctly at the time, but perhaps, I just missed the problem then???
