  1. Re: Can only make video with 255 frames

    It pays to look at the documentation of the functions:

    The error is here:


    hr = AVIStreamWrite(psCompressed, // stream pointer
    (m_nframe) * ONETICKTIME, // time of this frame...

    Hello all,

    I have code (found long time ago, ~2001) to make videos from OpenGL rendering in my view class. In my OnDraw() function I call the function SaveAsAvi(). This works as intended until I...

    Re: Freeglut in VS2010

    Doesn't seem to work. In the meantime I've found the function gluSphere and gluCylinder do what i want without needing any glut functions. Ah, the joys of trying to get code written around 2001 up to...

    Re: Freeglut in VS2010

    This travesty can hardly be called "documentation".

    Re: Freeglut in VS2010

    Still stuck. Is it possible I need to call glutInit somewhere first with freeglut? With the old glut version I didn't need this.

    Re: Freeglut in VS2010

    Well, as explained, it's also in Debug mode. When I run in Debug mode, I also get no useful info as to what the cause is and how to solve it.

    Re: Freeglut in VS2010

    Additional info:

    It appears to be that the only reason it works in Debug mode is that glut32.lib was in the additional dependencies in Debug configuration. When changing to freeglut.lib instead I...

    [RESOLVED] Freeglut in VS2010

    Hi,

    I'm making a call to glutSolidSphere somewhere in my program. When I compile in Debug configuration, a sphere can be correctly rendered. In Release configuration, the project compiles, the exe...

    I have decided to contact Dr. David H. Eberly, which is referenced as the source upon which the author in the first link I provided based himself upon. Dr. Eberly was kind enough to write an...

    glRasterPos3d(0.5, 0.5, 0.50 );

    Re: Extracting time stamps from pdf

    Anyway, I got an idea, I might use GetPosition and check if it is anywhere near the end of the file, if not just call ReadString again in a while loop. I'll first try that.

    InputFile.Open(FileName,CFile::modeRead|CFile::typeBinary))

    Let's me read a lot further but it still exits way before the actual end of the file.

    Re: Extracting time stamps from pdf

    Already did that. What if there are a gazillion instances? I want to automate it. I thought the ten lines above could do it. Obviously I was wrong.
