Any incoming stream needs to be decoded before any further transformation unless you use a pass-through mode. The decoding may be either hardware-based (such as NVidia GPU decoding supported by Live Transcoder or Intel QuickSync) or software-based.
Software decoding may be optimized in order to use processor resources optimally. This is why the Transcoder allows using multiple threads for video decoding. Let's see how you can utilize it.
In the transcoding scenario you need to point to video decoder blue rectangle (with a film on it) and then click on appeared gear button.
You'll see decoder settings dialog. In the Decoder drop-down list it will show "Default" option. This is a software decoder used by Nimble Transcoder by default.
Use Threads edit box to specify the number of sessions threads used for decoding in this this particular incoming stream. Now click OK and then save transcoding scenario to apply it to the server.
You can specify this separately to any decoder in any scenario
