Hi,

I am using ModuleCupertinoLiveOnTextToID3 from [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](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) and in method onFillChunkDataPacket() I can see a timestamp generated from Adobe Live Media Encoder. The timestamp is using “onFI”, not “onMetaData”. The example uses HLS streams which I have not tested yet. First I wanted to try a flash client. How can I modify the module to add new meta data? I would need access to the stream to call stream.sendDirect("@setDataFrame",“onMetaData”,data)

Using the other examples with onMetaData() will not work, because the method is not called for “onFI” and I am only interested in the encoder system time.

What else can I do? I want to pass the encoder system time to jw player and there call a javascript funktion

Thanks,

Ropoman

Hi,

Wowza should preserve the absolute timecodes passed through the onFI events to the output RTMP stream. You will need to be able to handle these events on JWPlayer.
