Hi

I was working on a project with ffmpeg 3.2.7 libraries,  and I need use tonemap filter to do a HDR to SDR convert, but tonemap is not implemented in 3.2.7. The ffmpeg libraries used by the project had been modified a lot, added some custom business feature, so It’s hard to upgrade ffmpeg. Thus I wander if I can and how to back port some version of tonemap implementation to 3.2.7? 

Thanks
