From: Cosmin Stejerean <cos...@cosmin.at> Some DolbyVision samples fail to parse currently due to mis-reading the el_bit_depth_minus8 field. Upon investigation it seems that the RPU syntax has been extended in an as of yet undocumented way by adding ext_mapping_idc and coding it together with el_bit_depth_minus8 together into a single 16 bit integer with the upper 8 bits for ext_mapping_idc and the lower 8 bits for el_bit_depth_minus8.
This can be observed in the output of the DoVi verifier, which shows how this is laid out. This patchset adds the new fields to dovi_meta and implements the code to parse and write this back out. Compared to the previous version it moves the fields to the end for ABI compatibility, bumps the minor version in lavu and splits this into a separate commit.
