Doing this the data-re command finds the metadata embedded in the video and extracts it to a file.
I run the same command against the same video after Wowza records it (a file with an extension of .mp4). I get the following error:
Stream map 'data-re' matches no streams.
It appears that when Wowza stores the video it strips the meta data. I assume this is also the case when Wowza transcodes a live video stream into a RTSP to distribute. Is there anyway to configure Wowza to preserve the metadata?
When recording through Wowza Streaming Engine Manager -> Application -> Incoming Streams -> Click the Red circle for the recording pop up window, you will then see "Recording Options" at the bottom of that pop-up.
With the check box for "Record Data" filled you will retain your meta-data in your recordings.
