Hardware Transcoding on DSM7

I can confirm for you:

  1. Hardware transcoding (without HDR tone mapping) is natively available on DSM 7 for Intel x86_64 processors (J3355 and above).

  2. Be certain to enable both transcoding options

  3. If you opt to use the Docker container overlay method (to layer Docker PMS on top of your native package), The J3455 and above CPUs will support HDR → SDR tone mapping.
