A question about using jpeg2000 #58

Hello, I'm sorry to bother you, I have a question when I use this project about jpeg2000. Should I download ffmpeg and openjpeg by myself? Thanks.

fracape commented 3 years ago

Yes, we used ffmpeg's implementation of jpeg2000 for our comparisons. You need to install it to use the evaluation scripts on your dataset.

YocurryC commented 3 years ago

Thanks for your answer! But just installing ffmpeg didn't work either. Does this project also need the OpenJPEG library compiled by C language? Or is my FFmpeg installation in the wrong directory? Sorry to bother you.

Please refer to https://ffmpeg.org/ffmpeg-codecs.html#jpeg2000 for ffmpeg

Hello, what are the versions of FFMpeg and JPEG2000. And the size of different pictures at the same compression level is the same

Hello, I am also unable to run JPEG2000. If it's convenient for you, could you please let me know which libraries I need to download? This would be a great help to me.
