First of all I'd like to say how lucky I am to have found your transcoder application! It works better than so many others!
I was wondering, x265 2.2 has been released for a few weeks now, is it possible to release an updated FFMPEG which includes this? or maybe even have it so that we can update the x265.exe rather than building it into the FFMPEG application? this way we can always have latest x265 build, which is in heavy development still.
