Set if frames carry timing information which the subclass can (generally) parse and provide.
In particular, intrinsic (rather than estimated) time can be obtained following a seek.
This value is reset during PAUSED->READY state changes. Subclasses must call this function from GstBaseParseClass::start
if they want to set a static value.
