4k is supported in FFmpeg for (at least) ten years.

I believe that strictly speaking HDR means logarithmic 
or float colour space support. FFmpeg does not support 
logarithmic colour space and float support is extremely 
limited (input only, will be converted to rgb48 / rgb64 
immediately).

x264 supports 9 and 10 bit encoding, x265 supports 
10 bit encoding, this is all supported by FFmpeg.

What kind of input do you have?
