You can take the advice already given: update ffmpeg!! Older versions of ffmpeg required an rgb2xyz command, but now the transform is done for you. You also mentioned that libopenjpeg was slower. Again, you need to update ffmpeg which will also hopefully update libopenjpeg. From my experience, libopenjpeg is faster and better than the native ffmpeg jpeg2000 encoder. Also you will encounter some colour issues in your output file, mostly that everything will look too green. A tool like Fraunhofer EasyDCP PLayer will apply the correct LUT that will fix this but from what I can see, you can't do this in ffmpeg as of yet. Here's some attempts of mine to get it working: https://ffmpeg.org/pipermail/ffmpeg-user/2016-November/034223.html The issue is described better on page 30/31 of this manual: https://www.easydcp.com/sync/manuals/easyDCP_Player_User_Manual.pdf Best, -Kieran. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
