org.apache.openmeetings.db.entity.record.FlvRecordingMetaData
contains meta data about each stream, for example if it is a screen sharing or audio/video stream. There is also a {@link Status} value{@link #streamStatus}, as long as this variable is not set to {@link Status.STOPPED}, the recording process will not proceed and start to convert all input sources to a single recording file. @author sebawagner
