           Summary: rtpjitterbuffer: buffering mode=slave outputs audio
                    buffers with duplicate pts

Sample rtsp audio stream which yields duplicate timestamps with rtpjitterbuffer

When the attached gdp-payloaded file is run through rtpjitterbuffer, with
mode=slave (the default), the output audio has buffers with duplicate pts, but
not with mode=buffer/synced/none. Those buffers all seem to contain silence
(see bug 746032).

Bad:
gst-launch-1.0 filesrc location=output-gdp-audio.bin ! gdpdepay !
rtpjitterbuffer ! rtpmp4adepay ! decodebin ! ...

Good:
gst-launch-1.0 filesrc location=output-gdp-audio.bin ! gdpdepay !
rtpjitterbuffer mode=buffer ! rtpmp4adepay ! decodebin ! ...

gst-launch-1.0 filesrc location=output-gdp-audio.bin ! gdpdepay !
rtpjitterbuffer mode=synced ! rtpmp4adepay ! decodebin ! ...

gst-launch-1.0 filesrc location=output-gdp-audio.bin ! gdpdepay !
rtpjitterbuffer mode=none ! rtpmp4adepay ! decodebin ! ...

All the incoming packets are sequential and evenly-spaced (captured from
gst-rtsp-server over a link-local network), so in theory there shouldn't be a
"discontinuity" like that.
