I'd like to know if Photon has supported the Dolby HDR IMF(mxf created by Dolby SIDK). attachment is the resulting CPL file created by IMFTrackFileCPLBuilder with the dolby vision mxf file.

Photon supports validation of Dolby HDR IMF. However IMFTrackFileCPLBuilder does not have extensive application support and do not recommend using it.
