The tag +is stripped from the output, and all offsets are adjusted for the tag +sizes, so that to the downstream element the stream will appear as if +there was no tag at all. Also, once the tag has been parsed, GstTagDemux +will try to determine the media type of the resulting stream and add a +source pad with the appropriate caps in order to facilitate auto-plugging. + +## Deriving from GstTagDemux + +Subclasses have to do four things: + + * In their base init function, they must add a pad template for the sink + pad to the element class, describing the media type they can parse in + the caps of the pad template. + * In their class init function, they must override + GST_TAG_DEMUX_CLASS(demux_klass)->identify_tag with their own identify + function. + * In their class init function, they must override + GST_TAG_DEMUX_CLASS(demux_klass)->parse_tag with their own parse + function. + * In their class init function, they must also set + GST_TAG_DEMUX_CLASS(demux_klass)->min_start_size and/or + GST_TAG_DEMUX_CLASS(demux_klass)->min_end_size to the minimum size required + for the identify function to decide whether the stream has a supported tag + or not.
