Quicktime and iTunes somehow use the ICC color profiles (that contain information about grayscale gamma and color gamut). With a color meter like the i1pro or color munki I can easily calibrate my wide gamut monitor and have an excellent picture.
However Plex support much more codecs and plays much better.
So my request is whether it would be possible to use the core video in OSX and not bypass the ICC profiles? I’m not sure if allready the gamma information is used perhaps I’m just missing the LUT color gamut correction? I coudl clearly see how by example green was not corrected on my calibrated monitor and a measurement confirmed this.
To elaborate a bit. If Plex uses the osx core graphics then it might be just the change of a constant from rgb colorspace to device colorspace. I’ll look into the source one of these days but the modification of another open source player was easy.
However I suspect Plex to use the linux kernel and bypass all osx functions?
This would be great. There are linux based open source calibration tools these days that could be added to e.g. the Plex Media Player on Raspberry Pi. Not sure how that would work without a GUI - maybe install one on same hardware and reapply back into plex somehow. I assume there would have to be an ICC profile somewhere in it. Of course I’m not sure how much different drivers etc affect this.
