Streaming uses a lot of CPU and is slow

Look into the following options:

  • [ ] compare source / target encoding to maybe skip transcoding all together
  • [ ] get HW acceleration to work
  • [ ] use different profiles / resolutions
  • [ ] use bigger HLS chunks
  • [ ] batch multiple HLS chunks together

@shimberger Did you had any time to read or test about this issue?

@elico I have not. Are you interested in helping out?

@shimberger I am not sure what you or others consider as high CPU usage. In streaming and compression there is always a conflict between CPU and DISK. You can spare one with the cost of the other but cannot spare both. There is a talk which gives couple good points about this issue and there is a link to it in this git: https://github.com/elico/nginx-hls-dash-stream-example
