Luis de Bethencourt eabcf66f2f glcolorconvert: fix comments that confuse gtk-doc 
GTK-Doc uses a special syntax for code documentation. A multiline comment that
starts with an additional '*' marks a documentation block that will be processed
by the GTK-Doc tools. So GTK-Doc is confused if a comment block starts with that
additional '*' but isn't meant to be processed. Removing this additional '*'.

Matthew Waters df6967c274 glcolorconvert: fix planar YUV download 
- sample the u and v planes properly
- output the correctly scaled u and v planes for different chroma block sizes

Matthew Waters a771b40474 glcolorconvert: fix UYVY download green screen 2017-12-09 19:31:47 +00:00
Matthew Waters ea711807d8 glcolrconvert: fix YUY2 download 
- The shader was outputing the wrong values compared with raw
  videotestsrc.
- deal with the texture edge properly.
- properly sample the 2x1 rectangle for the u and v values
- don't double sample the y value

Matthew Waters e6bd70d580 glcolorconvert: convert xRGB into ARGB properly 
The alpha channel might not be the last component so check which one
it is in and clobber that one instead.

Matthew Waters 2b82b78ef5 glmemory: reenable the texture_rg support for !eagl 
The GST_GL_HAVE_PLATFORM_EAGL is always defined we need to compare
against the value instead.

Sebastian Dröge f6ae4ab243 eagl: Disable usage of R and RG textures on iOS 
They don't work currently and just render zeroes, while the
fallback code path with LUM and LUM_ALPHA textures still works.

Matthew Waters 2279713aa0 gl/colorconvert: remove scratch texture for YUY2/UYVY 
We can get all our data from the one RG/LA texture with some shader magic.

Matthew Waters 132a233f7b gl/memory: implement GL_EXT_texture_rg support 
Which is used by default over the Luminance formats due to it
being color renderable with fbos (and deprecation/removal with
GL 3.x).

Matthew Waters 313dfbb500 gl/upload: switch the 'master' texture for YUY2, UYVY 
From d4bcef3204 on, using a RGBA
texture to hold the data causes the glmemory to have half width
and a scaling of [2, 1].  Using a LA texture solves this problem
however cannot be attached to the framebuffer for copying into
a RGBA texture.  Which will be solved by moving to EXT_texture_rg.

Matthew Waters 5efb69304a gl/colorconvert: fix up alpha clobbering 
Previously it would only work if the alpha value was in the last
component (RGBx, BGRx).  Now it works wherever the alpha value may
be (xRGB, xBGR, etc).
 2017-12-09 19:31:40 +00:00
Matthew Waters 07b6bfeaa7 gl/colorconvert: use the texture scaling from the gl memory 
The colorconvert values were not being used at all.

Matthew Waters 33091ff6a5 gl/mem: implement texture copying between formats with strides properly 
Previously, we used the width to determine the amount of data to be
copied using pbos.  This, makes it allocate enough data for the
the strides as well.

Jan Schmidt c891eedb79 glcolorconvert: Fix bt709 conversion matrices. 
Fix the sign on one entry in the bt.709 YUV->RGB conversion
matrix, and the corresponding inverse matrix. Fixes really
wrong colouring of some videos.

Matthew Waters 30c6efc432 gl/mem: allocate the memory per plane 
This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.

Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).

Should not lose any features/video formats.

Matthew Waters fba49c3463 gl: add colorconvert object that converts between color spaces/formats 
Currently used by both upload and download objects separately.
