   xxxxxxx - Change type of AVPixFmtDescriptor.flags from uint8_t to uint64_t.
   xxxxxxx - Change type of AVComponentDescriptor fields from uint16_t to int
             and drop bit packing.
+  xxxxxxx - Add step, offset, and depth to AVComponentDescriptor to replace
+            the deprecated step_minus1, offset_plus1, and depth_minus1.
