Control queue size before dropping

[Omar Hatem]

Hello,

We have a use case where we want to control the queue size before dropping
some frames. find code sample attached below.

*we used*:

   1. *max-size-time*=0, *max-size-bytes*=0. we set them by zero to disable
   their maximum.
   2. *max-size-buffers*=50. it's set to 50 before dropping
   3. *leaky*=2. to drop frames downstream.
   4. we added an identity element, and attached handoff_callback to memic
   latency of the downstream elements.

*Results*

   - playback is affected by the latency (slow).
   - observed queue size did not go beyond 4 buffers.

*Questions*

   - According to the documentation: the queue separates the downstream
   processing from the upstream processing (since it spawns a thread), why
   can't the queue reach a size of 50 buffers ?
   - If there is any alternative solution, please mention.
