Always keep probing the pipeline for the current position and compare
with the latest requested seek segment to detect if the seek boundaries
are being respected
The "switch-track" command can be used to switch tracks. The "type"
argument selects which track type to change (can be "audio", "video",
or "text"). The "index" argument selects which track of this type
to use: it can be either a number, which will be the Nth track of
the given type, or a number with a "+" or "-" prefix, which means
a relative change (eg, "+1" means "next track", "-1" means "previous
track").

When used with LD_PRELOAD, the application might use various pipelines
for several different thing, we need to make it possible to spcify a
specific pipeline (or set of pipelines) on which to run the scenario.
The format is in the form of:
scenario_name:pipelinename_pattern*
Improve buffer timestamp range check:
* Only do it for encoders or decoders
* Audio has an acceptable tolerance of 100ms
To do this, keep track of the caps on the pad and store
if it is dealing with audio or video
Allows both src and sink pad to keep track of the current caps, but
the duplicated caps check is still only applied to sink pads as
src pads can push the same caps multiple times when it isn't linked
Makes the result a bit more readable than a compact multi-line list.
FIXME: Figure out how to print the description of the issues (which can
spawn multiple lines) in a nice way.
Tag events are hard to track and check if properly serialized because
they mutate too much inside elements. There is no reliable way currently
to match a tag event pushed into an element and another tag event
leaving the element (other than if the pointers are actually the same).
This test will find the first input selector with more than one
sink pad, and cycle through them till it gets back to the original
one. Five seconds between switches. The test checks that some data
was sent from the input selector when each of the sink pads was
selected.
We know are sequential so whenever the wanted position is passed we
should execute the action.
This avoid issue with the tolerance when we have high rate playback
Testing on source pads can lead to false positives when pads are
unlinked. The caps event is sticky and will be pushed again later
when another buffer/event is pushed, leading to an acceptable
situation to push the caps twice.
