Question

How to republish stream with lower quality

Hey guys, I was wondering is there a way that I can receive stream on my broadcast server and then republish that stream with lower quality on the same broadcast server. I was reading server side API reference but I couldnt find anything like that.

Only thing I found is to use %i in FMLE Stream field and then broadcast same stream with different bitrates, but can I take live stream that is being broadcasted and republish it with lower quality/bitrate on the server side somehow?

Or there is another way to achieve this?

I am running FMS 4.5 and I am using FMLE to broadcast video to the server.

Thank you for your answers.

FMS can't transcode streams. What you could do is use FFMPEG to pull the stream from FMS and publish a transcoded stream back into FMS.

Alternately, you could use Wowza Media Server and their transcoder plugin (fairly easy), or Wowza and Xuggler (requires a fair amount of programming)

Thank you for your answer Jay, the first solution sounds good but I dont know how much would that be stable, that means that I need to use for example rtmpdump with ffmpeg, or ffmpeg has a way to dump live stream transcode and republish back?

FFMPEG supports RTMP, so it's capable of subscribing directly to the stream on the server, and publishing a transcoded stream back to the server without rtmpdump.

Of course, you'll need to develop your own code to instantiate ffmpeg with the appropriate flags.
