Hi to all,
I know that this question has been asked before, but did not find
a suitable solution for me. I get this
Xlib: unexpected async reply (sequence 0x1013)!
error message again and again.
I try to display a video window with OpenGL. It works fine for
the first ten frames, but then crashes.
I read the mailing list, and yes, there is a g_thread_init(0) in the
main function, as well as
gdk_threads_enter();
gtk_main();
gdk_threads_leave();
in the main.cc
When i try to add gdk_threads_enter() in my drawing routine, the
whole system hangs and nothing is shown.
I know that this error is produced if more than one routine tries to
talk to the X server, but how an i stop this ?? tried several things,
nothing worked :-(
My drawing routine is:
gint RecClient::refreshGdkGLVideo(GtkWidget *draw, GdkEvent *pEvent,
gpointer data)
{
cout << " Expose Video " << endl;
// Timeline abfragen ...
TimeLine *lTl = (TimeLine *) data;
/* if(my_images->next != NULL)
my_images = my_images->next;
else if(my_images->prev != NULL)
my_images = my_images->prev;
*/
Video::glxContext = glXCreateContext(GDK_DISPLAY(), Video::mVisual,
NULL, TRUE);
glXMakeCurrent(GDK_DISPLAY(), GDK_WINDOW_XWINDOW(draw->window),
Video::glxContext);
pthread_mutex_lock(&Video::video_mutex);
// gdk_threads_enter();
// glXWaitX();
if(draw->window) {
glDrawBuffer(GL_BACK);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Clear
// Screen And Depth Buffer
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, Video::texture);
glPixelStorei (GL_UNPACK_ALIGNMENT, 1);
if( Video::my_images ) {
gluBuild2DMipmaps( GL_TEXTURE_2D, // GLenum target,
3, // GLint components,
Video::my_images->width, // GLint width,
Video::my_images->height, //GLint height,
GL_RGB, // GLenum format,
GL_UNSIGNED_BYTE, // GLenum type,
Video::my_images->data); // const void
// *data )
glBegin(GL_QUADS);
glTexCoord2d(0.0, 0.0); glVertex2d(0.0, 1.0);
glTexCoord2d(1.0, 0.0); glVertex2d(1.0, 1.0);
glTexCoord2d(1.0, 1.0); glVertex2d(1.0, 0.0);
glTexCoord2d(0.0, 1.0); glVertex2d(0.0, 0.0);
glEnd();
glXWaitGL();
// glFlush();
glXSwapBuffers(GDK_DISPLAY(),
GDK_WINDOW_XWINDOW(draw->window));
// glFlush();
}
}
// glXWaitGL();
pthread_mutex_unlock(&Video::video_mutex);
return TRUE;
}
Many thank in advance
Stephan
p.S.: I'm not on the mailing list, so please reply dircetly.
