[gst-devel] Dropping buffers when pausing live stream

[Arnout Vandecappelle]

 Hoi all,

 My application is displaying live media that comes in over http or rtsp.  
Sometimes the stream has to be paused (because it is invisible and I don't 
want to waste CPU cycles on decoding).  However, simply pausing the pipeline 
will eventually disconnect the source because of overflowing socket buffers.  
Also, when playing again, I don't want to render a second of old data.

 The solution I had in mind is to port the dropping behaviour of queue to 
multiqueue.  Then I pause the sink elements, which makes the queues fill up 
and triggers the dropping.  When playing again, there is still a bit of stale 
data but it is recent stale data (and probably rendering delay will cause some 
more data to be dropped in the near future).

 Does this sound like a good idea?  Anybody have a better idea?

 Regards,
 Arnout
