+ This partial implementation of a decoder for DNxUncompressed video data

+ because the SMPTE RDD 50 specification is unfortunately not freely accessible.
+
+ It's therefor limited by the present export capabilities of Resolve (YUV444
+ variants, YUV422 16bit, and alpha support is missing). But also some ffmpeg
+ shortcomings are affecting the range of available formats (no YUV half and
+ float pixel formats and filters are provided by ffmpeg until now and RGB half
+ content always requires an alpha plane).
+
+ A wide range of DNxUncompressed formats are nevertheless already supported:
+
+ - YUV 4:2:2 8-/10-/12-bit
+ - RGB 8-/10-/12-bit/half/float
