-------
|
|
|
|
- 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.
|
|
|
|
- GstEvent, GstMessage register like GstFormat or GstQuery.
|
|
|
|
- query POSITION/DURATION return accuracy. Just a flag or accuracy percentage.
|
|
|
|
- add some sort of time/frame stepping functionality, either with a flag on the seek
|
|
event or some new seek event type. The idea would be to operate on the current
|
|
playback position instead of the current configured segment when doing the seek.
|
|
Idea is that frame stepping forwards can be done in the sinks, ie, just dropping
|
|
N frames/time, sending more complicated queries upstream which can ideally handle
|
|
those cases more efficiently too.

IMPLEMENTATION
|
|
--------------
|
|
|
|
- implement latency calculation for live sources.
|
|
|
|
- implement more QOS, see part-qos.txt.
|
|
|
|
- implement BUFFERSIZE.
|
|
|
|
- implement pad_block with probes.
|
|
|
|
|
|
DESIGN
|
|
------
|
|
|
|
- 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?
