x-post Belkin HiSpeed USB DVD Creator and Director
A question from a mate not on lingo-L: --- Hi folks, list, we have a problem. Has anyone reading this list ever worked with Director (MX) AND a Belkin "HiSpeed USB DVD creator"? This device takes a video signal a input and delivers it via USB to the computer - I'd say it's an A/D converter for video signals (coming along with some DVD creation software, why I assume they call the device "DVD creator"). We use it within an application that grabs the actual video signal on every frame and does some mathematics with it using the TrackThemColors Xtra (we've tried the free WebCam Xtra before, but this was too slow for our app). First it was running on a W2k pro-PC with an Athlon XP 3000+ and 1Gig RAM, now it's running on a WinXP pro (on the same machine). Always we switch on the video grabbing the application leads to a system crash or sometimes only Director crashes (fatal error) after 20-45 minutes. This happens whether we use 3D-lingo or not. We have installed all the newest drivers and BIOS, our experiments show that it doesn't have to do explicitly with the TrackThemColors Xtra (since if we use a simple USB-webcam for our video signal it runs and runs), but with the Belkin device. Any experiences greatly appreciated. Thanks in advance, Roman. _ Berndt [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).

Re: Frame events
Hi James, believe or not it is ways faster to execute code in enterframe. Time ago we had a thread on dirgames or director 3d. Please search the archives on nuttybar Cu Berndt On 18/3/04 12:32 pm, "Agustín María Rodríguez" <[EMAIL PROTECTED]> wrote: Is there a reason why you reaaly need this on prepareFrame? If not then it would be better to put that code into an enterFrame handler because is where Director expects the heavy code. Leave prepareFrame just for stuff like 3D synchro with bones and exitFrame for navigation between frames. Hi Agustín, Why do you think Director expects to find heavy code in the enterFrame() handler? I understand why you use exitFrame() for navigation. Moving to a new frame triggers the prepareFrame() handler, so you cannot do this from the prepareFrame() handler itself. Moving to a new frame on enterFrame() would mean that the Director has to go through all the hassle of calculating the pixels to display for the current frame, only to discover that it's actually meant to be somewhere else. Personally, I only use prepareFrame() for actions that must be carried out between beginSprite() and displaying the first frame, such as finding other sprites in the frame with the same behavior. If I do this, I set a flag so that the code in the prepareFrame() handler is never executed a second time. (An alternative is to place the instance on the actorList, perform the one-off action on stepFrame(), then remove the instance from the actorList). I don't think I ever use enterFrame() at all, since by that time the current frame is already visible. What advantages do you see in using enterFrame() rather than exitFrame()?

Re: detect sprites with a certain property
hi, you could check for scriptinstancelist <> [] Berndt Hi is it possible to loop through all sprites in the score and detect whether each sprite has a certain custom property. If the sprite has any custom properties then i can use repeat with k = 1 to the lastChannel repeat with l = 1 to sprite(k).count() if sprite(k).getPropAt(l) = #myBuiltInCursor then sprite(k).cursor = sprite(k).myBuiltInCursor else nothing end if end repeat end repeat but this fails when a sprite has no properties as it returns a "handler not in object error". so is it poosible to test for whether a sprite has any custom properties at all or not. chhers Lee Blinco Multimedia Developer AVR Productions +44 (0)1462 819603 [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).

Re: get and set pixel
Hi,
dunno how much it slows, but use an instance e.g.
myImage = member("firstImg").image
repeat with xx = 1 to 450
repeat with yy = 1 to 400
rgbval = myImage.getPixel(xx, yy)
-- some calculations here and then
myImage.setPixel(xx,yy, newrgbval)
end repeat
end repeat

Hi List
I am reading an image and drawing some of the pixels
onto another image cast member.
I am using this code similar to this :
repeat with xx = 1 to 450
repeat with yy = 1 to 400
rgbval = member("firstImg").image.getPixel(xx, yy)
-- some calculations here and then
member("secondImg").image.setPixel(xx,yy, newrgbval)
end repeat
end repeat
This is all working fine, except how slow it is.
Do you have any tips on how to fasten this process?
(is there any way of analysing an image object quicker than this
with imaging lingo?)
thanks for all answers

[x-post] director xdk update
hi, Macromedia Director XDK October 5, 2004 The latest release of the Director XDK has been updated for Director MX 2004 version 10.1. The XDK includes both functional updates and bug fixes. The functional updates to the XDK include an index to all interfaces and methods and a new scripting xtra example. In addition there are many bugs fixed within the documentation. Finally, developers will now find information about how developers can prepare their Macintosh Xtras for cross-platform projector publishing and information about global variables used within JavaScript syntax, both being new features found in Director MX 2004. http://www.macromedia.com/support/xtras/xdks/dmx_xdk.html Berndt [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).
