           Summary: [basertppayload] Provide a GstBufferPool for output
                    rtp buffers
    Classification: Platform
           Product: GStreamer
           Version: unspecified

            Status: NEW

Right now most (all?) payloaders will create new rtp buffers for their output.

The size of those buffers is always limited by the MTU, we could therefore have
a convenience GstBufferPool which those payloaders could use, providing
pre-allocated buffers of that size, with the proper Meta set on them and
therefore avoiding creating/freeing buffers all the time.

A quick glance at profiles shows that creating/freeing all those buffers
(instead of re-using them) account for 25-50% of the time spent in payloaders
:(
