GI.Gst.Structs.CapsFeatures

Contents

Description

GstCaps to add requirements for additional features for a specific #GstStructure. Caps structures with the same name but with a non-equal set of caps features are not compatible. If a pad supports multiple sets of features it has to add multiple equal structures with different feature sets to the caps.

Empty GstCapsFeatures that only contain GstCapsFeatures as created by gst_caps_features_new_any() are equal to any other #GstCapsFeatures and can be used to specify that any #GstCapsFeatures would be supported, e.g. for elements that don't touch buffer memory. GstCapsFeatures are considered non-fixed and during negotiation some #GstCapsFeatures have to be selected.

Examples for caps features would be the requirement of a specific #GstMemory types or the requirement of having a specific #GstMeta on the buffer. Features are given as a string of the format "memory:GstMemoryTypeName" or "meta:GstMetaAPIName".
