I'm looking for a way to convert non-linear colorspace to linear RGB using the BT.1886 transfer function with custom gamma. Neither zscale, scale or colorspace filters in latest FFmpeg builds seem to support it. I found a post on zimg/z.lib Github (https://github.com/sekrit-twc/zimg/issues/61) suggesting that BT.1886 support code was checked into the zimg/z.lib project in Jan 2017, but I haven't seen any reference to it in zscale filter documentation (even though it's based on z.lib).
Can it be done?
