i am using Antmedia Entreprise edition on AWS with 4x CPU and 16Gb RAM. I am sending a flux from OBS with 1080p / 10Mbits or 2.5Mbits via Gigabit wired network, using hardware encoding on Windows (Quadro K620).

I am using the WebRTCAppEE channel, with H264 enabled (not VP8), one adaptative streaming settings (1080p / 2Mbits) and HLS disabled.

The server pick up the flux, i can see it on both the test player and my web embedded player, but i got an awful quality, very compressed. I tried to set settings.encoding.preset=medium with no luck.

I tested to record my OBS output with "same as stream", the quality is very good.

I think there is a problem in the AntMedia transcoding process but i can't figure out where it is..

Any idea ? Thanks !

    Decreasing the quality from 10Mbits to 2Mbits yeah generally decreases the quality. What's your quality expectation about 1080p - 2Mbps stream? – faraway Jun 10 '20 at 08:35
  • The problem here is far worse than 2Mbits compression. I recorded the output of OBS (with 1080p/2Mbits) and the result is way better than what i can see in Antmedia after transcoding and played back by the webRTC player. It looks more like a bad transcoding preset in Antmedia, but i don't know where it's configured. I am now trying to play with Red5Pro (on which Antmedia is based) and it seems that there is a REST API to configure the transcoder which is automated on the Antmedia side (via the web interface), but i did not figured how to configure more deeply Antmedia. – maigre Jun 14 '20 at 18:12
