[gst-devel] how is buffering percentage implemented in playbin

[Jyoti]

I am writing an application where in I want to show the buffering status.
Is it not possible to monitor the level of queue in an application?

My motto is to display the buffering status something as below.

+---------------------------------------------------------------------------------
+
* *|*                          Buffering Progress Bar*
|
 |
|
 |    |*=======*|...........|...........|...........|...........|...........|...........|...........|...........|
|
 |    0      10     20     30     40      50    60     70     80     90
100      |
* |    20%
complete
|*
 |     |<------------------------  *Total
Duration*------------------------>|     |
 |
|
+----------------------------------------------------------------------------------+


I want to continuously show how much percent is been downloaded and how much
is
remaining. And also I want to start the playback only after say 10% of the
total data is
downloaded so as to get the uninterrupted playback.

Can you please suggest some ideas on this.

Thanks,
Jyoti
