Plan for 0.11
=============
First attempt at making a list of tasks in rougly chronological order.
* General cleanup
- Remove deprecated methods
- Cleanup structs + PADDING
- ..
* Add GstFlowReturn for events (and query)
* add return structure for events and query
* Make GstMiniObject a simple boxed type
- Move copy and free function to structure
- convert GstBuffer, GstEvent, GstMessage, GstQuery,
* Convert GstCaps to GstMiniObject
* Incremental caps
- Remove array from caps ?
- make caps iterator
* Make GstBufferMetadata
- Make functions to register metadata
- Make common metadata: timeinfo, memory data, video data
- Remove GstBuffer Fields
- Make methods to add metadata to buffers.
* Negotiation of metadata
- figure out if we need to negotiate the metadata on the caps or if we can
gracefully degrade when an element doesn't understand the metadata.
* Rework reverse negotiation
- _alloc_buffer() never returns changed caps. It can return a return
value when the caller should recheck the allowed caps.
- _alloc_buffer() takes input GstBuffer prototype (or NULL)
- upstream event to notify of a downstream caps change
* Incremental event progation
- certain events would be sticky on a pad like for caps
- rules for pushing an event downstream
- right before pushing a buffer
- after link operation
- activate for most serialized downstream events
* GstSegment changes
- remove segment accumulation
- add accumulated time to the event
- apply segment info to pads
- add method on pads to get/adjust sync offset
- add method on pads to query current running_time
