2020-10-04	qcam: viewfinder_gl: Add shader to render packed YUV formats	Laurent Pinchart
	The shader supports all 4 packed 8-bit YUV variants. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-10-04	qcam: viewfinder_gl: Merge the semi-planar UV and VU shaders	Laurent Pinchart
	Use macros to select the U and V pattern, to avoid code duplication between the two semi-planar shaders. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-10-04	qcam: viewfinder_gl: Support #define in shaders	Laurent Pinchart
	Prepare the infrastructure to support defining preprocessor macros in shaders: - Rename the fragmentShaderSrc_ member to fragmentShaderFile_ to reflect better that it contains a file name, not shader source code - Add a new fragmentShaderDefines_ member to store preprocessor macros - Prepend the macros to the shader source before compiling it Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-10-04	qcam: viewfinder_gl: Rename shader files	Laurent Pinchart
	Rename shader files to prepare for packed YUYV support: - The NV prefix isn't a good match for packed (or for 3-planar) formats, replace it with a YUV prefix - Use .frag and .vert extensions to differentiate between fragment and vertex shaders Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-10-04	qcam: viewfinder_gl: Hardcode the vertex shader file name	Laurent Pinchart
	The GL renderer uses the same vertex shader for all formats. Hardcode the file name instead of storing it in a member variable. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-10-04	qcam: viewfinder_gl: Don't store texture IDs in class members	Laurent Pinchart
	The texture IDs can easily and cheaply be retrieved from the textures, there's no need to store them in class members. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-09-15	qcam: Add ViewFinderGL class to accelerate the format conversion	Show Liu
	The viewfinderGL accelerates the format conversion by using OpenGL ES shader. The minimum Qt version is bumped to v5.4, as QOpenGLWidget wasn't available before that.
