The fact that FFmpeg does not contain a native h264 encoder 
(but has to use an external library) is probably a limitation 
of FFmpeg, limitations of specific h264 encoders like 
openh264 are not limitations of FFmpeg.

Before using lossless h264 encoding, please make sure that 
your intended decoder supports it (only FFmpeg supports 
decoding of lossless h264).
