[Mesa-dev] [PATCH 2/2] st/vdapu: use lanczos filter for scaling v4

HIGH_QUALITY_SCALING_L2 to HIGH_QUALTIY_SCALING_L7 uses lanczos filter with number representing the size of the sinc window. v3: avoid L8 and L9 to allow for other scaling algrithms v4 (chk): rebased on master Signed-off-by: Nayan Deshmukh ---

Hi Nayan, This quick hack was just to prove Christian's idea, and for your reference. I don't have multi GPU system, and only had a very brief test on single GPU, so it might be some difference on your multi GPU system. we have to dig more into it. Regards, Leo On 09/05/2016 03:51 AM, Nayan

Re: [Mesa-dev] [PATCH 2/2] st/vdapu: use lanczos filter for scaling v4

Hi Leo, I thought so. As Michel suggested present extension needs a linear buffer and he and Christian agreed that we should have a separate linear buffer for this. But I still don't understand the code in vl_winsys_dri3.c so I am not sure how this could be implemented. Regards, Nayan. On Tue,

Re: [Mesa-dev] [PATCH 2/2] st/vdapu: use lanczos filter for scaling v4

Hi Leo, I have tested your patch with my mplayer and it gives error when I try to increase the size of the window. It gives the following error:- X11 error: BadAlloc (insufficient resources for operation) X11 error: BadDrawable (invalid Pixmap or Window parameter) X11 error: BadPixmap (invalid

Re: [Mesa-dev] [PATCH 2/2] st/vdapu: use lanczos filter for scaling v4

Hi Nayan, About the Prime, I think you have to do is to separate decoder render buffer and presentation back buffer, and copy back and forth between them for presentation and update. You might refer to similar implement in glx and egl from loader_dri3_helper.c by grep "is_different_gpu"
