Hi,
I've done some work recently on GStreamer to handle pixel aspect ratio. I tested this yesterday on my matrox card with XDirectFB. The XDirectFB
doesn't report the physical dimensions correctly; reporting something
close to 5:4 instead of the 4:3 of my TV. I assume it's also not
possible for XDirectFB to figure this out automatically, since a TV
doesn't have any probing capabilities ?
I vaguely recall at some point in XFree86 3.x having to override this somewhere when autoprobing the monitor fails. I can't remember where, does anyone know where this is configured in X ? And does this change at all in XDirectFB, or is it maybe something that's not implemented in XDirectFB ?
For now I just forced the PAR to be 16/15 when the pixel dimensions are
720x576. Is this correct ? Are there people that for example run PAL
720x576 and have it output to 16:9 instead ?
720x576 at 16:9 is very common - The majority of movies on DVDs encoded for PAL use this resolution and format. With 16:9 television sales increasing while 4:3 sales are decreasing, 720x576 16:9 is likely to become the most common resolution and format for standard definition European video displays.
