Re: GetFrameImage throws exception

<t>Ok if I write it this way it works:<br/> <br/> camera->GetFrameImage(frame, width, height, 0, 8, 0));<br/> <br/> This is, without sending out a buffer. So It's obvious it's a size thing.<br/> <br/> Since my buffer has to be of size:<br/> <br/> (PixelWidth x PixelHeight x (BitsPerPixel / 8))<br/> ...

When I try to use GetFrameImage() I get this error: Unhandled exception at 0x77e78197 in Texture Project.exe: 0xC0000005: Access violation reading location 0x0a0a0a0e. All other functions works ok. I have used this function before, but I get this error when trying to use this DLL. This is my Debug L...

GetFrameImage in float buffer instead of BYTE buffer

<t>Hello,<br/> <br/> I'm trying to use OptiTrack SDK in Unity, but since I can only get the Texture buffer in float form (from 0.0 to 1.0 instead of BYTE from 0 to 255). Is there a function to get the frame image in the float form? Or what do you recommend to do the conversion? Since doing a for sta...

Re: Heap corruption problem

Thanks for the reply. That is not my case, since I'm asking for a 8-bit per pixel buffer. And the size of the buffer is right, (PixelWidth x PixelHeight x (BitsPerPixel / 8)) => (640 x 480 x (8 / 8)) = 307200. And that is the size of my buffer, 307200, so the buffer is large enough. I realized that ...

Heap corruption problem

If I comment out the line that is calling cvConvertImage(), it works well. Otherwise, I get this error: http://img13.imageshack.us/img13/4011/69751645.png "Windows has triggered a breakpoint in cvsample.exe. This may be due to a corruption of the heap, which indicates a bug in cvsample.exe or any of...

Re: OptiTrack + OpenCV

Yep thanks, I already manage to solve that.
But anyway, I think that working with 8bits instead of 32 it's far better, so I'm trying to figure that out.
