Hello All,

SUBJET: Performer + PBUFFER + Dmedia Buffer

We still fighting with Performer, to use a PBUFFER window, with the
DIGITAL_MEDIA_PBUFFER attribute.

The PBUFFER is created with:

  static int PBufferAttribs [] = {
        GLX_DIGITAL_MEDIA_PBUFFER_SGIX, True,
        GLX_PRESERVED_CONTENTS_SGIX, True,
        (int) None
        };

static int FBAttrs[] = {
    GLX_DRAWABLE_TYPE_SGIX, GLX_WINDOW_BIT_SGIX | GLX_PBUFFER_BIT_SGIX,
    GLX_RENDER_TYPE_SGIX,
    GLX_RGBA_BIT_SGIX,
    PFFB_RED_SIZE, 5,
    PFFB_BLUE_SIZE, 5,
    PFFB_GREEN_SIZE, 5,
    PFFB_ALPHA_SIZE, 1,
    GLX_DEPTH_SIZE, 24,
    None,
};

static void OpenPbuf(pfPipeWindow *pw)
{
    pfPipe *p;
    pfWSDrawable gxw;
    pfWSConnection dsp;
    int xs=0, ys=0, wxs, wys, num, screen, ret;
    Window pbuf;

GLXFBConfigSGIX *fbc;
XVisualInfo * vis;

dsp = pfGetCurWSConnection();
screen = pfGetPWinScreen(pw);

fbc = glXChooseFBConfigSGIX(dsp, 0, FBAttrs, &num);
vis = glXGetVisualFromFBConfigSGIX(dsp, *fbc);

printf("Num matching FBConfigs on display 0x%p=%s screen %d is %d
VisID:%X",
dsp, XDisplayString(dsp), screen, num, vis->visualid);

pfPWinFBConfig(pw, *fbc);

    gxw = glXCreateGLXPbufferSGIX( dsp, * fbc, xs, ys, PBufferAttribs);
    pfPWinWSDrawable(pw, dsp, gxw);
    }

CASE 1:
If I do not create the PBUFFER then Performer opens the Pbuffer by
himself,
but the Pbuffer can not be associated to a Digital media Buffer,
because it has not the correct properties.

pbufAssociate(display,
(GLXPbufferSGIX ) getPbuffer(), getDmparams(),getDmbuffer() )
;

RESULT:
X Error of failed request: BadDrawable (invalid Pixmap or Window
parameter)
  Major opcode of failed request: 141 (GLX)
  Minor opcode of failed request: 16 (X_GLXVendorPrivate)
  Resource id in failed request: 0x0
  Serial number of failed request: 0
  Current serial number in output stream: 24

CASE 2:
If I Try to set these properties, create the pbuffer by myself and then
use it with
pfPWinWSDrawable then I get as result:

RESULT:
> PF Notice: Num matching FBConfigs on display
> 0x100212f8=:0.0 screen 0 is 2
> X Error of failed request: BadAlloc (insufficient resources for
> operation)
> Major opcode of failed request: 141 (GLX)
> Minor opcode of failed request: 5 (X_GLXMakeCurrent)
> Serial number of failed request: 0
> Current serial number in output stream: 48
>

What am I doing wrong ?

Thanks in advance to any help.

Hector Viguer.
