Some collected notes porting plugins to GStreamer 0.9.
|
||
|
|
|
||
|
|
|
||
|
|
* General notes
|
||
|
|
|
||
|
|
Consider using the base classes. There are base classes for sources,
|
||
|
|
sinks, and "transformers", which are plugins that have the same caps on
|
||
|
|
their source and sink sides.
|
||
|
|
|
||
|
|
These base classes offer interfaces that are much more appropriate to
|
||
|
|
the function of specific plugins than the general GstElement interface.
|
||
|
|
|
||
|
|
|
||
|
|
* Functions that changed
|
||
|
|
|
||
|
|
** gst_pad_use_explicit_caps
|
||
|
|
** gst_pad_set_explicit_caps
|
||
|
|
|
||
|
|
Not needed; just set the caps on the first buffer you push out.
|
||
|
|
|
||
|
|
** gst_element_set_loop_function
|
||
|
|
|
||
|
|
Use gst_pad_set_loop_function. Note that loop-based elements participate
|
||
|
|
more in the scheduling process in 0.9, so you'll need to add hooks to
|
||
|
|
the activate function to start up a task.
|
||
|
|
|
||
|
|
refcounting:
|
||
|
|
_get_ accessors
|
||
|
|
GValue, GstObject, and refcounts (arrrrgh)
