Yes, FFmpeg supports both lossless jpeg and jpeg-ls, the codecs names 
are ljpeg and jpegls.

FFmpeg contains a native j2k encoder that does not support lossless 
encoding, and supports encoding j2k via the external library libopenjpeg.
I don't know of my head how to lossless encode with libopenjpeg, 
perhaps try -fixed_quality.
