GstValidateScenario

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.

Possible configurations (see GST_VALIDATE_CONFIG):

scenario-action-execution-interval: Sets the interval in milliseconds (1/1000ths of a second), between which actions will be executed, setting it to 0 means "execute in idle". The default value is 10ms.

GstValidateAction

The GstValidateAction defined to be executed as part of a scenario

Only access it from the default main context.

Functions

gst_validate_action_get_clocktime

gboolean
gst_validate_action_get_clocktime (GstValidateScenario * scenario,
                                   GstValidateAction * action,

                                   GstClockTime * retval)

Get a time value for the name parameter of an action. This method should be called to retrieve and compute a timed value of a given action. It will first try to retrieve the value as a double, then get it as a string and execute any formula taking into account the 'position' and 'duration' variables. And it will always convert that value to a GstClockTime.

Parameters:

scenario –

The GstValidateScenario from which to get a time for a parameter of an action

action –

The action from which to retrieve the time for name parameter.

name –

The name of the parameter for which to retrieve a time

retval ( [out]) –

The return value for the wanted time

Returns –

TRUE if the time value could be retrieved/computed or FALSE otherwise

Parameters:

scenario (GstValidate.Scenario) –

The GstValidate.Scenario from which to get a time for a parameter of an action

action (GstValidate.Action) –

The action from which to retrieve the time for name parameter.

name (String) –

possible_variables (const gchar *) –

The name of the variables that can be used to compute the value of the parameter. For example for the start value of a seek action, we will accept to take 'duration' which will be replace by the total duration of the stream on which the action is executed.

def (const gchar *) –

The default value of a parameter as a string, should be NULL for mandatory streams.

The action is checking some state from objects in the pipeline. It means that it can be used as 'check' in different action which have a check "sub action", such as the 'wait' action type. This implies that the action can be executed from any thread and not only from the scenario thread as other types.
