From: Sebastian Dröge Date: Tue, 2 Apr 2013 20:13:22 +0000 (+0200) Subject: capsfeatures: Add GST_CAPS_FEATURES_ANY X-Git-Tag: 1.1.1~176 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65c650d7d4f4f814950cbc90c1369abaeaed0a22;p=platform%2Fupstream%2Fgstreamer.git capsfeatures: Add GST_CAPS_FEATURES_ANY This is equal to any other caps features but results in unfixed caps. It would be used by elements that only look at the buffer metadata or are currently working in passthrough mode, and as such don't care about any specific features. --- diff --git a/docs/gst/gstreamer-sections.txt b/docs/gst/gstreamer-sections.txt index d743b48..5183a12 100644 --- a/docs/gst/gstreamer-sections.txt +++ b/docs/gst/gstreamer-sections.txt @@ -459,6 +459,7 @@ gst_caps_intersect_mode_get_type GstCapsFeatures gst_caps_features_new gst_caps_features_new_empty +gst_caps_features_new_any gst_caps_features_new_id gst_caps_features_new_id_valist gst_caps_features_new_valist @@ -472,6 +473,7 @@ gst_caps_features_to_string gst_caps_features_set_parent_refcount gst_caps_features_is_equal +gst_caps_features_is_any gst_caps_features_contains gst_caps_features_contains_id diff --git a/gst/gstcaps.c b/gst/gstcaps.c index 0e8c798..aaa1131 100644 --- a/gst/gstcaps.c +++ b/gst/gstcaps.c @@ -1075,12 +1075,17 @@ gboolean gst_caps_is_fixed (const GstCaps * caps) { GstStructure *structure; + GstCapsFeatures *features; g_return_val_if_fail (GST_IS_CAPS (caps), FALSE); if (GST_CAPS_LEN (caps) != 1) return FALSE; + features = gst_caps_get_features (caps, 0); + if (features && gst_caps_features_is_any (features)) + return FALSE; + structure = gst_caps_get_structure_unchecked (caps, 0); return gst_structure_foreach (structure, gst_caps_is_fixed_foreach, NULL); diff --git a/gst/gstcapsfeatures.c b/gst/gstcapsfeatures.c index 3a50254..56cd2d9 100644 --- a/gst/gstcapsfeatures.c +++ b/gst/gstcapsfeatures.c @@ -55,9 +55,11 @@ struct _GstCapsFeatures GType type; gint *parent_refcount; GArray *array; + gboolean is_any; }; GType _gst_caps_features_type = 0; +GstCapsFeatures *_gst_caps_features_any = NULL; GstCapsFeatures *_gst_caps_features_memory_system_memory = NULL; static GQuark _gst_caps_feature_memory_system_memory = 0; @@ -82,6 +84,7 @@ _priv_gst_caps_features_initialize (void) g_value_register_transform_func (_gst_caps_features_type, G_TYPE_STRING, gst_caps_features_transform_to_string); + _gst_caps_features_any = gst_caps_features_new_any (); _gst_caps_features_memory_system_memory = gst_caps_features_new_id (_gst_caps_feature_memory_system_memory, 0); @@ -148,6 +151,7 @@ gst_caps_features_new_empty (void) features->type = _gst_caps_features_type; features->parent_refcount = NULL; features->array = g_array_new (FALSE, FALSE, sizeof (GQuark)); + features->is_any = FALSE; GST_TRACE ("created caps features %p", features); @@ -155,6 +159,28 @@ gst_caps_features_new_empty (void) } /** + * gst_caps_features_new_any: + * + * Creates a new, ANY #GstCapsFeatures.
