Changes in the 0.9 version
|
|
--------------------------
|
|
|
|
- Refcounting and API revised for thread safety, see rules in
|
|
docs/design/part-MT-refcounting.txt
|
|
|
|
- Scheduling is now done by the elements, they start/stop
|
|
processing threads themselves. This removes the need for
|
|
a separate scheduler.
|
|
|
|
- State changes now happen from sink to source. This makes sure
|
|
that downstream elements are ready to process data when upstream
|
|
starts producing.
|
|
|
|
- EOS/ERROR/... does not change the state of elements anymore. This
|
|
means that when the application sets the state on an element, it
|
|
remains in this state.
|
|
|
|
- GMainLoop integration. Information on the state of the pipeline
|
|
is now received in the mainloop via the GstBus.
|
|
|
|
- Events move separate from the datastream, this allows for both
|
|
in and out of sync delivery of events.
|
|
|
|
- Generic _pull() replaced by _pull_region() so that random access
|
|
can be made faster.
|
|
|
|
- data passing happens from PAUSED, called the preroll phase. In this
|
|
state no data is rendered but it is queued in the sinks.
|
|
|
|
- negotiation simplified. Caps are now attached to buffers and travel
|
|
along with the datastream.
|
|
|
|
- GstBuffer is now subclassable.
|
|
|
|
- Ghostpads now look and feel like real pads.
|
|
|
|
- New Seeking/flushing policy.
|
|
|
|
- Addition of base classes and helper functions in the core to abstract
|
|
away the harder parts of plugin development.
