Hi, I want to get an stream from a drone (RTSP or SRT protocols) and then to make some tests at different bitrates, so I need to change the bitrate of output to some required values, lets say 750, 1024, etc, to know how it will be in that bitrat, so how is stablished the bitrate?

@Luis Molina Martinez, changing the bitrate of a stream is done by transcoding. Check the Wowza Transcoder feature that it built into Wowza Streaming Engine; see [https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming](https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming).

Make sure to have enough server resources (especially CPU or GPU) for transcoding. Here are some benchmarks: [https://www.wowza.com/docs/wowza-transcoder-performance-benchmark](https://www.wowza.com/docs/wowza-transcoder-performance-benchmark)
