GstMetaTransformFunction

gstreamer c types

Function called for each meta in buffer as a result of performing a transformation on transbuf. Additional type specific transform data is passed to the function as data.

Implementations should check the type of the transform and parse additional type specific fields in data that should be used to update the metadata on transbuf.

alias GstMetaTransformFunction = int function(GstBuffer* transbuf, GstMeta* meta, GstBuffer* buffer, GQuark type, void* data)

Return Value

TRUE if the transform could be performed
