Is there anyway to turn transcoding off and allow to only remux? the transcoding takes so much cpu usage.
Maybe, but that's a vague question.
Vague answer is possibly, it depends...
You need to provide more information on what client device/version you're using that's transcoding and with what source and what settings.
I am running my service on a mac mini and 500/500 but it seems to trans code more than not.
Ensure that the quality setting is always set to "Original", then the server will only remux.
Transcoding is generally controlled by the client. You can set the quality settings in the client. Anything but “Original” requires the server to transcode. The web player also always requires transcoding as it can’t play the native content.
The client side can not be controlled on the server correct? It will have to be adjust on the device being used to watch the stream.
Correct. The server will transcode if the client requests a resolution or bitrate less than the original source. To ensure that transcoding doesn't happen, the client should request "Original". Similarly, for viewing in the web UI, choose the highest available (1080@10Mbps). While the server may remux, it is not actually transcoding, just putting the streams in a different container.
When playing in a browser from the web UI it transcodes AC-3 dolby audio (from CABLE or OTA sources) to AAC audio that the web UI can play. It also needs to transcode mpeg2 video to H.264.
Since TVE streams have H.264 video and AAC, not AC-3 audio, it remuxes them instead of transcoding.
