Hi, those of us without HDR displays but still trying to futureproof our collections by getting 4k versions of movies have been kind of screwed, because the HDR>SDR tonemapping in Coreelec is not really useable - the saturation, contrast, etc just aren’t there.
The Windows version of Kodi has includes ACES Filmic tonemapping for awhile now, and tonemapping HDR>SDR with it near perfectly matches the native SDR appearance.
Per Kodi developer jjd-uk, this tonemapping has now been ported to GLES and works on ARM devices.
Any chance this could be added to a nightly or a 19.4 version of Coreelec? It would be a godsend for those of us in the above situation.
From the thread at kodi:
ARM devices can do ACES Filmic and Hable tonemapping, it’s just that nobody got round to doing it for v19, it’s now been recently added to the code for v20.
… Alternatively as you’re a CE user, then perhaps you can ask on their forums if someone would be willing to backport it to v19, it was added in [GLES] add ACES and Hable tone mapping by lrusak · Pull Request #20157 · xbmc/xbmc · GitHub if anyone wants to take a look at what’s needed.
