How can I use ffmpeg to convert images to the JPEG 2000 format?

To convert images to the JPEG 2000 format using ffmpeg, you can use the following command:

ffmpeg -i inputimage.jpg -c:v libopenjpeg outputimage.jp2

This command will take an input image in JPEG format (inputimage.jpg) and convert it to the JPEG 2000 format (outputimage.jp2) using the libopenjpeg codec in ffmpeg.
