The Buffer tracer prints out information about each buffer that goes out of a source pad of an element.
Pipeline
The following pipeline demonstrates the use of the buffer tracer and the results obtained.
GST_DEBUG="GST_TRACER:7" GST_TRACERS="buffer" gst-launch-1.0 videotestsrc ! fakesink sync=true
Output
