/**
* SECTION:gst-validate-scenario
* @short_description: A GstValidateScenario represents a set of actions to be executed on a pipeline.
*
* A #GstValidateScenario represents the scenario that will be executed on a #GstPipeline.
* It is basically an ordered list of #GstValidateAction that will be executed during the
* execution of the pipeline.
*
* To be able to simply define that list of actions, a dedicated file format is used. This
* file format is based on the #GstStructure serialized format which is a basic, type aware,
* key value format. It takes the type of the action as first coma separeted field, and then
* the key values pair of the form 'parameter=value' are separated by comas. The values
* type will be guessed if not casted as in 'parameter=(string)value'. You can force the type
* guessing system to actually know what type you want by giving it the right hints. For example
* to make sure the value is a double, you should add a decimal (ie '1' will be concidered as a
* int, but '1.0' will be concidered as a double and '"1.0"' will be concidered as a string)
*
* For example to represent a seek action, you should add the following line in the '.scenario'
* file.
*
* |[
* seek, playback_time=10.0, start=0.0, flags=accurate+flush
* ]|
*
*
* The files to be used as scenario should have a '.scenario' extension and
* should be placed either in $USER_DATA_DIR/gstreamer-1.0/validate-scenario ,
* $GST_DATADIR/gstreamer-1.0/validate-scenario or in a path defined in the
* $GST_VALIDATE_SCENARIOS_PATH environment variable.
*
* Each line in the '.scenario' file represent an action (you can also use \ at the end of a line
* write a single action on multiple lines). Usually you should start you scenario with a 'description'
* "config" action in order for the user to have more information about the scenario. It can contain
* a 'summary' field which is a string explaning what the scenario does and then several info fields
* about the scenario. You can find more info about it running:
*
* |[
* gst-validate-1.0 --list-action-types description
* ]|
*
* So a basic scenario file that will seek three times and stop would look like:
*
* |[
*
* description, summary="Seeks at 1.0 to 2.0 then at \
* 3.0 to 0.0 and then seeks at \
* 1.0 to 2.0 for 1.0 second (between 2.0 and 3.0).", \
* seek=true, duration=5.0, min-media-duration=4.0
* seek, playback_time=1.0, rate=1.0, start=2.0, flags=accurate+flush
* seek, playback_time=3.0, rate=1.0, start=0.0, flags=accurate+flush
* seek, playback_time=1.0, rate=1.0, start=2.0, stop=3.0, flags=accurate+flush
* ]|
*
* Many action types have been implemented to help users define their own scenarios.
* For example there are:
* <itemizedlist><title>Action type examples:</title>
* <listitem><para>
* seek: Seeks into the stream
* </para></listitem>
* <listitem><para>
* play: Set the pipeline state to GST_STATE_PLAYING
* </para></listitem>
* <listitem><para>
* pause: Set the pipeline state to GST_STATE_PAUSED
* </para></listitem>
* <listitem><para>
* stop: Stop the execution of the pipeline. NOTE: That action actually post a
* #GST_MESSAGE_REQUEST_STATE (requesting #GST_STATE_NULL) message on the bus and
* the application should quit.
* </para></listitem>
* <listitem><para>
* ...
* </para></listitem>
* </itemizedlist>
*
* To get all the details about the registered action types, you can list them all with:
*
* |[
* gst-validate-1.0 --list-action-types
* ]|
*
* and (includes transcoding specific action types):
*
* |[
* gst-validate-transcoding-1.0 --list-action-types
* ]|
*
* You can also register new types yourself thanks to #gst_validate_add_action_type. And you will be able
* to print the action types details thanks to the #gst_validate_print_action_types function in your own
* tool.
*
* Many scenarios are distributed with gst-validate, you can list them all using:
*
* |[
* gst-validate-1.0 --list-scenarios
* ]|
