We need a mechanism to transport extra data in a GstBuffer. Unlike caps the content is likely to change for each buffer.



  1. GstStructure in GstBuffer

  2. GstTaglist in GstBuffer

  3. syncronized downstream events
  4. Store GstStructures in GstIndex

GstStructure is also use in GstTaglist. The structure can be hierarchical. We could require that the producer uses its element name as a root tag. This way the taglist could carry multiple data-sets identified in a unique way. Elements that can use the data need to know the name of the element that created it.
