- changing an object's name after construction is not allowed. Checks are performed
when adding objects to parents that no duplicate names are used, changing the name
to a duplicate name after adding it is therefore allowed and voids internal
consistency.
- implement return values from events in addition to the gboolean. This should be
done by making the event contain a GstStructure with input/output values, similar
to GstQuery. A typical use case is performing a non-accurate seek to a keyframe,
after the seek you want to get the new stream time that will actually be used to
update the slider bar.
- unlinking pads in the PAUSED state needs to make sure the stream thread is not
executing code. Can this be done with a flush to unlock all downstream chain
functions? Do we do this automatically or let the app handle this?
- implement clock selection as explained in part-gstpipeline.txt.
- when a pipeline with a live source goes to PAUSED again, a sample is prerolled
in the sinks. This sample should be discarded, possibly with a flush event
started from the source.
- convert framerate to GstFraction in GstCaps.
- implement latency calculation for live sources.
- implement master/slave clocks.
- implement QOS.
- implement BUFFERSIZE.
- make bin_bus_handler a vmethod so subclasses can use their own implementation
or chain to the parent.
- make it possible to seek on other formats than bytes in basesrc.
- GstFormat quarks, get_name.
- GstQuery quark, get_name.
- GstEvent, GstMessage register like GstFormat or GstQuery.
- unblocking while seeking. gst_element_flush_pads (GstElement, gboolean);
- make GstCapsFlags instead of the #define for GST_CAPS_FLAGS_ANY.
- query POSITION/DURATION return accuracy. Just a flag or accuracy percentage.
