Version-Release number of selected component (if applicable): Nouveau testing livecd How reproducible: Always Steps to Reproduce: 1. Open a video in totem 2. Set it to 100% size 3. Resize window to be smaller Actual results: Video size is the same, the smaller window just clips it. Expected results: Video size should be reduced. Additional info:

Also present on nVidia Corporation NV6 [Vanta/Vanta LT] [10de:002c] (rev 15)

I don't believe this is a bug. As far as I can recall, the hw overlay on nv4 (nv4/nv5/nv6) series hw can't do downscaling. Are you able to try with the nv driver to confirm? The blit adaptor should be able to downscale just fine however.
Comment 3 Ivo Anjo 2009-04-05 11:53:42 EDT
I thought it might be a hardware limitation too, but wasn't sure. I re-tested with the blit adaptor and downscaling works. I tried with nv but it only offers the "NV Video Blitter", no overlay. Is there any other way to test?
Comment 4 Ben Skeggs 2009-04-05 18:41:02 EDT
Ah right, nv doesn't have any support for the overlay on that chipset. I'll mark this as not a bug, but I'll think more about possibly using the blitter as the default Xv adaptor on at least this chipset. Thank you!
Comment 5 Ivo Anjo 2009-04-25 12:17:50 EDT
Just for completeness, I've tested using the nvidia proprietary driver (it's kinda amazing it still works on an nvidia vanta and they haven't dropped support for it), and yeah with the overlay there is no downscaling, while using the blitter there is -- so it's the same as with nouveau.
