In general, the multmedia add-on does work on XP. I think it something special specific with the ebook, the MPEG file, or the XP machine you are using.
First guesses: It is probably something like a missing or broken Codec on XP (the program to decompress and play the MPEG). It might also be something to do with XP PC, but I think this is less likely.
Try playing the same MPEG directly in media player in Accessories? - if it doesn't play this will confirm the codec theory. You need to find which codec the video uses, and make sure you have it on XP.
Try the demo book? - does it work?
Where did you get this particular MPEG file? If you made it, what Codec did you use?
The source .mpg files plays fine on XP Media player. That cancels the theory of codec incompartibility.
The XP has been installed with clean installation and there is on other programs installed (...just a clean installation). That cancels any incompartibility with other programs.
The problem is that when I click at the link the windows opens, the video clip plays, I can here the voice but I see nothing, no image!!! Could you explain that??
I found a solution with clicking a compination of Ctrl+1+left click on "play" symbol. Doing that I can see the video playing in full screen mode and then when it stops the window returns in its actual size. As you understand it's not a valid solution for my customers.
Can you give me the fragment of the code you have for linking the video?
Can you try the demo ebook from ebookpower on your machine - does this work?
For your video, could it be something to do with the Window size? If the Window size is different from the video maybe the PC is not fast enough to rescale it to the Window, and run XP at the same time, while it is playing. Maybe try experimenting with this?
Is this an AVI or MPEG? Do you know what Codec it uses?
If the video and/or ebook is not too large can you ZIP it up, upload it to your site with FTP, and send me a link to download it
I can try it on XP as well. I don't have XP in my home PCs, but I do in the office, so I can test it there is next few days, see if I find a clue
It's not the ebook but it's a working example which will show you the problem in XP.
P.S. By the way, when you will click on the video link and see the window open, if you drag it using your mouse then the video plays OK!!!! (.....I hate XP!!!). May be it has a relation with the window rendering in XP..
>2. Some kind of (wierd) focus problem with XP's rendering.
>When you don't see the video, what do you see in the window? Do you see the video player controls even if the video is not visible?
When I don't see the video I see a blank window with all the video player controls in their position. All works OK (voice, window opens OK, video controls) EXCEPT the video motion.
>1. A speed problem?
My pc is rather speedy. PIV 1.6 Gz, 512 ram, 40gb HD 7,200 rpm.
>But here is the issue, if you move a window, depending on it's position it can be harder or easier for the CPU to render it depending, primarily, on it's horizontal position.
And that's exactly the weird think!
>This would be more of an issue with a slow machine, a slow operating system (XP), or a high-frame rate video or a vid which uses a computationally intense codec.
I used Adobe Premiere and made the export choosing "Save for Web" and then choosing MPEG and 2x Cd-Rom PAL 352X288, I don't know the codec but if there was a problem with the codec I would have also problem on using XP media player to open the source .mpg files. But these files plays OK.
>If you try playing your video full-screen (just for testing) - that works, right?
How can I play my video full-screen? Is there any other code I have to use? Or you mean if I use Ctrl+2 after the window opens? If I do this, then "yes" it works.
>Does it make a diffeence if you click on the controls, missing video, or just the Window title bar ?
No, the only difference is when I drag the window to another position as I told you before. Then I see it OK!..(..strange rendering problem).
And something else. If I do this, (...drag the window) then all the other videos I have in my ebook play OK!!! That means, they open OK and they don't need to grag them!!! (strange eh????). Is that make sense????
>Also you didn't answer me about the demo ebook from ebook power. Does this work on your XP machine?
Yes, it plays Ok. And also it plays OK both the pop up window and the full screen with the airplane landing you have. Did you use .avi or .mpg? What's the code you use to play these videos?
Now the only thing is to download the .zip from my site an test it. If you experience the same problem then I have to focus on the .mpg files.
