We need to implement play ads using RAF whileSCTE-35 marker or ID3 tag is detected from the HLS live stream.
We already added timedMetaData listener in Video, but the listener is not calling.
Is there any other listener to identify SCTE-35 marker, any sample URL contains SCTE-35 marker.
Hi,
Did You set "timedMetaDataSelectionKey" field of SG video node?
To recive any timed meta data You need to set this field. example below shows a way to select all keys:
SGVideoNode.timedMetaDataSelectionKeys = ["*"]
For more reading visit this documentation site and search for "timedMetaDataSelectionKeys ", "timedMetaData " fields.
Hi aBlaze,
Thanks for your reply, I added timedMetaDataSelectionKey for Video node only,
Please check the sample code.

Hi, srikanth, frankly Yours code worked well for me.
only thing i have changed it was setting URL.
