GstQueue
<!-- ##### SECTION Short_Description ##### -->
Simple asynchronous data queue.
<!-- ##### SECTION Long_Description ##### -->
<para>
Simple data queue. Data is queued till max_level buffers any subsequent buffers
sent to this filter will block until free space becomes available in the buffer.
The queue is typically used in conjunction with a thread.
</para>
<para>
You can query how many buffers are queued with the level argument.
</para>
<para>
The default queue length is set to 100.
</para>
<para>
The queue blocks by default.

<!-- ##### SIGNAL GstQueue::overrun ##### -->
<para>
Reports that the buffer became full (overrun).
A buffer is full if the total amount of data inside it (num-buffers, time,
size) is higher than the boundary values which can be set through the GObject
properties.
</para>
@gstqueue: the object which received the signal.

<para>
Reports that the buffer became empty (underrun).
A buffer is empty if the total amount of data inside it (num-buffers, time,
size) is lower than the boundary values which can be set through the GObject
properties.
