Now I have JPEG-LS both decoder and encoder. Use FFmpeg "-pred x" option to set near-lossless compression. Please test and consider for inclusion. Encoder is not relying on MPV* funcs because MPVinit won't let encode RGB images, and as I don't need MjpegContext it's easier to write own header than use mjpegpictureheader.
tested: ../ffmpeg_g -y -f pgmyuv -i vsynth1/%02d.pgm -vcodec jpegls -pix_fmt rgb24 ./data/a-jpegls.avi
no error messages but image looks like random noise ...
