But H.265 encoding is time consuming.
I nominate johnson876 for the understatement of the year award! No offense intended, but without GPGPU encoding optimization or a Xeon multiprocessor work station, H265 is prohibitively slow. And where exactly are you going to play the H265 files? Its a bit premature to be used as a mainstream codec by the public.
Nice to see you guys have an eye for the future, and are developing tools in this area. I suspect you'll have more complaints when trying to use H265 than success stories however.
