Please describe the problem:
Since G.711 (a-law & u-law) do not use fixed samplerate, it is necessary to
pass the rate information in the caps structure. Current implementation of
gstrtppcm(a/u)depay.c define output caps as follows:

"audio/x-(a/u)law, " "channels = (int) 1"

Even this "rate" field is omitted, the pipeline works. However, it causes the
caps renegotiation to happen with every buffer that is passed from depayloader
to decoder. This is quite a performance drawback.

Steps to reproduce:


Actual results:


Expected results:


Does this happen every time?
