- Optimize negotiation. We currently do a get_caps() call when we link pads,

- pad block has several issues:
|
||||
* can't block on selected things, like push, pull, pad_alloc, events, ...
|
||||
* can't check why the block happened. We should also be able to get the item/
|
||||
reason that blocked the pad.
|
||||
* it only blocks on datapassing. When EOS, the block never happens but ideally
|
||||
should because pad block should inform the app when there is no dataflow.
|
||||
* blocking should only happen from one thread. If one thread does pad_alloc
|
||||
and another a push, the push might be busy while the block callback is done.
|
||||
* maybe this name is overloaded. We need to look at some more use cases before

||||
trying to fix this.

Buffering Query
|
||||
---------------
|
||||
|
||||
It is possible to query the amount of buffering performed in the pipeline, which
|
||||
is defined as the amount of data made available at the source. This amount is
|
||||
expressed in some GstFormat and is usually compared to the duration or position
|
||||
of the media stream in the same GstFormat.
|
||||
|
||||
The buffering query should return the following information:
|
||||
|
||||
- format
|
||||
- position
|
||||
- duration
|
||||
|
||||
The format is of lesser importance, the ratio of position versus duration can be
|
||||
used to calculate the percentage of available media. It should also be possible
|
||||
for the application to calculate the expected time when the complete file will
|
||||
be buffered.
