My configuration supports CLUTTER_FEATURE_TEXTURE_RECTANGLE. So I think
doing a clutter.Texture() returns a NPOTS texture:
clutter-texture.c (clutter_texture_init):
if (clutter_feature_available (CLUTTER_FEATURE_TEXTURE_RECTANGLE))
{
priv->target_type = CGL_TEXTURE_RECTANGLE_ARB;
priv->is_tiled = FALSE;
printf("rect_arb set\n"); // This is printed to screen
So shouldn't the video be played back on NPOTS too? Does putting the
ffmpegcolorspace into the pipeline affect anything? (gl/clutter/gst
newbie here!)
If I run the program via remote X (I don't care about this scenario), I
see this:
(refvideo.py:19256): Tidy-WARNING **: TidyTextureReflection doesn't
support tiled textures..
Local runs produce no errors.
It is a dell laptop and I have the proprietary Nvidia driver installed
(compiz works at level 2, not 3).
BTW, the documentation for ClutterTexture lists "tiled" property as
defaulting to true. In the code, I see that it is false for GL but true
for X11 displays.
Could you elaborate on what is broken in tidy-texture-reflection?
Thanks,
Ashwin
