There was a problem hiding this comment.
Initialise the playlistMetadata map as an empty map so you don't need to do a null or empty check later.
logger.info(CLASS_NAME + " Scheduled stream is now live: " + stream.getName());
AMFDataObj amfData = new AMFDataObj();
playlistMetadata.forEach(amfData::put);
if (amfData.size() > 0)
stream.getPublisher().getStream().sendDirect("onMetadata", amfData);

Add configuration property
streamPublisherPassPlaylistAttributesAsMetadatato specify playlist attributes (can be separated by commas) that will be sent inonMetaDataevents.This PR introduces the ability to add custom playlist attributes and pass them, on playlist start, as timed metadata, to the internal stream. This makes it possible to write other modules that can access those timed metadata and create appropriate DASH event messages (https://www.wowza.com/docs/convert-timed-metadata-from-amf-to-emsg-using-the-wowza-streaming-engine-java-api) or HLS ID3 tags (https://www.wowza.com/docs/how-to-convert-ontextdata-events-in-a-live-or-vod-stream-to-timed-events-id3-tags-in-an-apple-hls-stream).
The example usage would be to mark some playlists as ad blocks:
then set server/application configuration property
streamPublisherPassPlaylistAttributesAsMetadatatoadBreak,adBreakType(please notice that attributes can be separated by a comma) and use this information to create SCTE-35 DASH emsg or HLS ID3 tags.
