I'm trying to achieve a lossy JPEG 2000 output with FFMPEG, but no success so far.
Using this command line:
ffmpeg -i input.dpx -pix_fmt yuv420p -vcodec libopenjpeg output.jp2
As a result I get lossless output, which is a default setting for JPEG 2000. I tried -b:v and -q:v, but they both have no impact to the output.
Does anyone know a command that changes the quality/compress the output?
Any kind of help is really appreciated. Thank you!
