Ultra HDR is a true HDR image format, and is backcompatible. libultrahdr is the reference codec for the Ultra HDR format. The codecs that support the format can render the HDR intent of the image on HDR displays; other codecs can still decode and display the SDR intent of the image.

Improve encoder input argument validation #224

Closed ram-mohan closed 1 month ago

ram-mohan commented 1 month ago

encoder apis [2-4] accept compressed sdr intent as an argument. Validate this arg in depth. Briefly,

  1. return error if the input has no valid jpeg
  2. pick first if the input has multiple jpeg images

fixes #166
