Up until now, talking in-depth about userspace tracing was deliberately avoided because it merits special treatment, hence this part devoted to it. We'll now look at the why of it, and we'll examine eBPF user tracing in two categories: static and dynamic.

For a long time I believed that echo cancellers had no place inside GStreamer. The theory was that GStreamer was too high level and would never be able to provide accurate enough delay information for any canceller to work.
