Libdovi error with Vapoursynth #234

Closed Amaraldo closed 1 year ago

Amaraldo commented 1 year ago

The dovi_tool is a great tool. I am trying to create lossless FEL reconstructed Dolby Vision screenshots using dovi_tool and Vapoursynth but I keep getting this error "No entry point found in /opt/homebrew/lib/vapoursynth/libdovi.3.1.2.dylib" when running Vapoursynth scripts.

Is this related to the fact I'm using an m1 mac? I'd appreciate any help or workaround.

Why do you have libdovi installed in the VS plugins? It shouldn't be there.

Ah. My mistake. Where should it be?

Also, is it possible to reconstruct the FEL with lossless re-encoding for short spliced Dolby content? I am trying to create a database comparing the quality of standard HDR10 screenshots with their Dolby Vision counterparts. Lossy re-encoding defeats the purpose as any gains afforded by the FEL are lost in the re-encode. Thanks again!
