[Conrad Cooke (Palm GBU)]

Mark,

I have it figured out - have programmed 2 - they connect to my Manta - please come up and verify

       I had used this at an old piece of code in C:

               pixbuf = gdk_pixbuf_new_from_data(
                       GST_BUFFER_DATA(new_buffer), GDK_COLORSPACE_RGB,
                       FALSE, 8, width, height,
                       GST_ROUND_UP_4(3 * width), _destroy_pixbuf,
                       new_buffer);


I am continuing to have trouble with this.  Most every combination I try ends up with a distorted image.  Further, there doesn't appear to be a pygst counterpart to GST_ROUND_UP_4, but it is easy enough to compute.

def f(num):
    return (num + 3) & ~3

If it is of help to anyone out there, my caps read as follows:

video/x-raw-rgb, bpp=(int)32, depth=(int)24, endianness=(int)4321, red_mask=(int)65280, green_mask=(int)16711680, blue_mask=(int)-16777216, width=(int)512, height=(int)277, framerate=(fraction)24/1, pixel-aspect-ratio=(fraction)1/1, color-matrix=(string)sdtv, chroma-site=(string)jpeg;

What's the thinking and solution behind mapping this buffer into a gdk pixbuf successfully?

You have them in the code I pasted. They should be in the the buffer
caps.

Yes, of course.  Thanks again for that.

In pygst for future searchers:

caps = last_frame.get_caps()[0]
width = int(caps["width"])
height = int(caps["height"])
