I wanted to add that when there is data coming in the samples and buffers
should be consistent, but because the ultimate source is a walkie-talkie
like interface, there is not always audio coming in. We only send data to
gstreamer when there is audio coming into the system over the network, we
do not send silence. I did try starting the stream before the application
so there was essentially always audio flowing in, but that made no
All the best,
