List of supported media MediaContainerConfigurations (or a single one).
EventTriggerOptions are derived automatically as follows:
The size of the prebuffer in milliseconds. It must be at least 4000 ms. A sensible value for this property is in the interval [4000, 8000].
In order to provide some context to recording event, it is a good user experience
to also have the recording of a few seconds before the event occurs.
This exactly is the prebuffer. A camera will constantly store the last
x seconds (the
prebufferLength) to provide more context to a given event.
