I'm happy to say I've made some progress.<br>
<br>
I strung a gtk window together (very untidily!), but it was to see if and/or<br>
what I was getting into the pixbuf. I now have the stream playing and<br>
displaying the video.<br>
<br>
To my mind this means the *messaging*, *gst_app_sink_pull_sample*,<br>
*gst_sample_get_buffer*, *gst_buffer_map* and *gdk_pixbuf_new_from_data* are<br>
working as they should - and I get image data where it's expected.<br>
<br>
All I added for the experiment was a *gtk_image_set_from_pixbuf* and<br>
*gtk_widget_queue_draw* to display the images. Probably messed with the<br>
g_main_loop_run, but messaging and other stuff still works. My conclusion is<br>
gstreamer is doing what it should be.<br>
<br>
I am now pretty sure my problems arise from converting the gst-buffer to an<br>
IplImage for OpenCV to work on.<br>
<br>
I'll also try David's suggestion and incorporate more of the gst-plugins-bad<br>
opencv stuff.<br>
<br>
More to follow...<br>
