# Step 4: Inject the new RPU back into the video stream # We take the original base layer and inject the converted RPU cmd_inject = ["dovi_tool", "inject-rpu", "-i", self.temp_hevc, "-o", "final_p8.hevc", "-r", "converted_rpu.bin"] subprocess.run(cmd_inject, check=True) convert dolby vision profile 7 to profile 8 new
Summary: Dolby Vision uses metadata profiles specifying how dynamic HDR metadata is packaged. Profile 7 (commonly used for HDR10 + Dolby Vision dynamic metadata, compatible with many streaming workflows) and Profile 8 (an IMF/Single-layer approach used in some deliverable workflows) differ in container, bitstream placement, and metadata embedding. Converting between them is nontrivial: it’s less a simple “rewrap” and more about repackaging metadata and ensuring compliance with Dolby’s specs and playback compatibility. Below is a practical, actionable guide covering what the profiles are, why conversion may be needed, the constraints, typical workflows, tools, and step-by-step procedures you can follow.
