1. A method for generating High Dynamic Range (HDR) and/or Wide Color Gamut (WCG) video data from an encoded video data stream, the method comprising:
extracting, by a non-HDR and/or non-WCG video decoder, metadata signaled for a video data set in an encoded video data stream comprising encoded non-HDR and/or non-WCG video data,
wherein said signaled metadata structure includes at least one reshaping parameter for a video data reshaping transfer function signaled in a supplemental enhancement information message of said encoded video data stream and/or video usability information message of said encoded video data stream,
wherein said at least one reshaping parameter are relevant to the video data set signaled at a picture level in the encoded video data stream;
decoding, by the non-HDR and/or non-WCG video decoder, the encoded non-HDR and/or non-WCG video data to produce decoded non-HDR and/or non-WCG video data;
determining the video data reshaping transfer function based on the extracted metadata structure;
generating reshaped HDR and/or WCG video data as output data by applying the decoded non-HDR and/or non-WCG video data to the video data reshaping transfer function.
