FFmpeg saving rtmp live stream cuts off after 3 minutes - ffmpeg

Question

I was playing with ffmpeg and was able to save a live stream to a file. The command to do so is:
ffmpeg -re -i "rtmp://<ip addr>/livestream live=1" -f h264 test.flv
However, I have tested this twice, and both times ffmpeg stops after grabbing 3:28 worth of live video.
The entire output is here:
bash-4.2$ ffmpeg -re -i "rtmp://<ip addr>/livestream live=1" -vcodec libx264 -f h264 test.flv

Although I don't see any errors. It just looks like ffmpeg thought the stream had ended? But that's not possible since it's a live stream.

Answer 1

This is most likely related to swf verification being performed on the server side (see 'swfVfy' flag). You could try something as follows and see if the stream gets further.
ffmpeg -i "rtmp:///livestream live=1 swfVfy=1 swfUrl=url_to_the flash_player_here" -y test.flv
Unfortunately though, in my case I could not get ffmpeg's swfVfy to work, and have exapmles of the same streams working fine with rtmpdump.
