/* The files in this folder are included multiple times with different
|
|
* definitions for these macros. The macros are given the following arguments:
|
|
*
|
|
* GST_GL_EXT_BEGIN:
|
|
*
|
|
* @name: a unique symbol name for this feature
|
|
*
|
|
* @min_gl_major: the major part of the minimum GL version where these
|
|
* functions are available in core, or 255 if it isn't available in
|
|
* any version.
|
|
* @min_gl_minor: the minor part of the minimum GL version where these
|
|
* functions are available in core, or 255 if it isn't available in
|
|
* any version.
|
|
*
|
|
* @gles_availability: flags to specify which versions of GLES the
|
|
* functions are available in. Should be a combination of
|
|
* GST_GL_API_GLES and GST_GL_API_GLES2.
|
|
*
|
|
* @extension_suffixes: A zero-separated list of suffixes in a
|
|
* string. These are appended to the extension name to get a complete
|
|
* extension name to try. The suffix is also appended to all of the
|
|
* function names. The suffix can optionally include a ':' to specify
|
|
* an alternate suffix for the function names.
|
|
*
|
|
* @extension_names: A list of extension names to try. If any of these
|
|
* extensions match then it will be used.
