I've tested libopenjpeg in FFmpeg, and it really is lossless by default.
Here's the commandline I've used:

$ ffmpeg -i /home/pb/Videos/test-source/football_422_ntsc.y4m -y -threads 8 -an -g 1 -c:v libopenjpeg jpeg2000-libopenjpeg.avi

Moritz already mentioned that FFV1 is built-in in FFmpeg, so you should
work out of the box.
I've prepared a simple cheatsheet, if that might help:
