De-jittering/PLC of audio/x-raw from appsrc

[Sean DuBois]

Hi!

Currently I am receiving audio/x-raw via an appsrc from an external API,
and the only thing I know about the audio is the duration of each buffer
(PTS should just be the time of the pipeline) however I am having an issue
with discontinuity

Every so often there will be very small gaps in audio, and since I am
mixing a live source I will hear and it is very jarring. I have tried an
audiorate but it drops all the samples (is there something I need to
set/tune?)

And here is what an identity is printing

Are you setting the timestamp of the buffer properly? --gst-debug=basesink:5 and see if buffers are reaching the sink late
