Dolby Vision Profile 7 → Profile 8 conversion — Feature specification

Goal: Add a feature that converts Dolby Vision streams encoded as Profile 7 (dual-layer: base layer HDR10 + enhancement layer) into Dolby Vision Profile 8 (single-layer, merged bitstream), preserving visual fidelity, metadata, and compliance with Dolby Vision spec where possible.

Profile 8 serves as the universal translator. By converting to Profile 8.1, you strip the secondary enhancement layer while retaining the crucial RPU (Reference Processing Unit) metadata [1, 5]. This allows the video to remain a single-layer, 10-bit file that is cross-compatible with HDR10 hardware while still providing the dynamic, frame-by-frame adjustments of Dolby Vision [2, 5].

: Converting prevents issues like stuttering or incorrect tone mapping on devices like the Nvidia Shield Dolby Vision Profile 7 → Profile 8 conversion

Profile 8.1 Structure: A Single Layer (SL) format that combines an HDR10 Base Layer with RPU metadata. Conversion Process This allows the video to remain a single-layer,
