use of androidx.media3.extractor.metadata.emsg.EventMessage in project media by androidx.

the class EventSampleStreamTest method skipDataThenUpdateStreamContinueToReadDoNotSkippedMoreThanAvailable.

/**
 * Tests that {@link EventSampleStream#skipData(long)} will only skip to the point right after it
 * last event. A following {@link EventSampleStream#updateEventStream(EventStream, boolean)} will
 * update the underlying event stream and keep the timestamp the stream has skipped to, so the
 * next {@link EventSampleStream#readData(FormatHolder, DecoderInputBuffer, int)} call will return
 * sample data from the skipped position.
