The pause action instructs the pipeline to go to paused state and then
return to playing. It has the argument 'duration', that indicates the
duration for which the pipeline will remain in paused
Reports now point to Issues, that are uniquely identified and have
translatable descriptions. This way we are going to be able to uniquely
identify the issues and applications can enable/disable checks for
specific elements.
That was never set, but it is needed for the reporter to properly add
reports to the runner.
We still keep a reference on the monitor to make things simpler
This way we can report issues from a scenario
Also add a Seek aread to the known areas list
We now need to pass the runner to the scenario instead of the
pipeline as the GstQaReporter interface needs it.
A scenario correspond to a suite of action to execute on a pipeline,
for the time being, we only support seeking the pipeline, but in the
future we can imagine doing some queries, setting pipeline state, etc...
The scenario can be loaded thanks to the GST_QA_SCENARIO environment
variable, making it usable with any existant application, in case, the
application can be used interactively, the user should either, not load
any scenario or let the application run without interacting with it.
