    Default Packetizer events

    Is there an interface for live streams that I can use to implement event listeners? In the console I've noticed that there is extensive logging of packetizer events - is there a way to listen to these events?

    I've looked at the ILiveStreamPacketizerActionNotify interface and it has methods for packetizer create, init and destroy events. For VOD streams, we have the IHTTPStreamerCupertinoVODActionNotify interface, which has more useful methods such as onOpen, onFillChunkStart and onFillChunkEnd.

    We do not have a way to listen for these events. We may add this in the future but we do not have it at this time.

    Thanks Charlie. I think it'd be a really great feature of the API, if it included the ActionNotify classes for all streams.

    Alternatively, is there a way to ensure chunks are always equal in duration? The console displays the packetizer event for the first 10 chunks and I've noticed that chunks or Cupertino streams can vary.

    Chunks have to break on key frames, so the more uniform these are the more uniform chunk duration will be.
