Masterbackend is set to high cpu usage.


The transcode is part of the HLS stream and is converting a 1080i source (already fully written) to 704x400 size (not sure what other parameters are set on this transcode).


I have tried 2 HLS transcode simultaneously and the CPU load rises to 60 - 70% so the CPU is able to take the processing - its just that a single transcode cannot max out the CPU.

Any other ideas why this is only using 40% of the CPU for a single HLS transcode?
