Description

Functions

gst_glsl_profile_from_string ()

GstGLSLProfile
gst_glsl_profile_from_string (const gchar *string);

Parameters

string

a GLSL version string

Returns

the GstGLSLProfile of string or GST_GLSL_PROFILE_NONE on error

gst_glsl_profile_to_string ()

const gchar *
gst_glsl_profile_to_string (GstGLSLProfile profile);

Parameters

profile

a GstGLSLProfile

Returns

the name for profile or NULL on error.

[nullable]

gst_glsl_version_from_string ()

GstGLSLVersion
gst_glsl_version_from_string (const gchar *string);

Parameters

string

a GLSL version string

Returns

the GstGLSLVersion of string or GST_GLSL_VERSION_NONE on error

gst_glsl_version_to_string ()

const gchar *
gst_glsl_version_to_string (GstGLSLVersion version);

Parameters

version

a GstGLSLVersion

Returns

the name of version or NULL on error.

[nullable]

gst_glsl_version_profile_from_string ()

gboolean
gst_glsl_version_profile_from_string (const gchar *string,
                                      GstGLSLVersion *version_ret,
                                      GstGLSLProfile *profile_ret);

Note: this function expects either a version GLSL preprocesser directive or a valid GLSL version and/or profile.

Parameters

string	a valid GLSL version string
version_ret	resulting GstGLSLVersion.	[out]
profile_ret	resulting GstGLSLVersion.	[out]

Returns

TRUE if a valid version string was found, FALSE otherwise

gst_glsl_version_profile_to_string ()

gchar *
gst_glsl_version_profile_to_string (GstGLSLVersion version,
                                    GstGLSLProfile profile);

Parameters

version	a GstGLSLVersion
profile	a GstGLSLVersion

Returns

the combined GLSL version string for version and profile

gst_glsl_string_get_version_profile ()

gboolean
gst_glsl_string_get_version_profile (const gchar *s,
                                     GstGLSLVersion *version,
                                     GstGLSLProfile *profile);

Note: this function first searches the first 1 kilobytes for a version preprocessor directive and then executes gst_glsl_version_profile_from_string().

Parameters

s	string to search for a valid version string
version	resulting GstGLSLVersion.	[out]
profile	resulting GstGLSLProfile.	[out]

Returns

TRUE if a valid version string was found, FALSE otherwise

gst_gl_context_supports_glsl_profile_version ()

gboolean
gst_gl_context_supports_glsl_profile_version
                               (GstGLContext *context,
                                GstGLSLVersion version,
                                GstGLSLProfile profile);

Parameters

context	a GstGLContext
version	a GstGLSLVersion
profile	a GstGLSLProfile

Returns

Whether context supports the combination of version with profile

gst_gl_version_to_glsl_version ()

GstGLSLVersion
gst_gl_version_to_glsl_version (GstGLAPI gl_api,
                                gint maj,
                                gint min);

Parameters

gl_api	the GstGLAPI
maj	the major GL version
min	the minor GL version

Returns

The minimum supported GstGLSLVersion available for gl_api , maj and min
