I would like to get the NetStream width/height when receiving a RTMFP stream. This is important because the video component needs different measures when, for example, the user receives a 4:3 or a 16:9 stream.
Unfortunately, the onMetaData callback for NetStream does not work as it does for RTMP streams.
Is there a workaround?
You might try using different ports and see if the onMetaData gives you anything different. I believe the 3 main ones are: 1935, 443 and 80.
