Convert flv to j2c

What is the difference between .flv and .j2c?

Description: An FLV file is a flash-compatible video file exported by the Flash Video Exporter plug-in (included with Adobe Animate) or other program with FLV file support. It consists of a short header, interleaved audio, video, and metadata packets. The file stores audio and video data in a similar format used by standard Flash (.SWF) files.; The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
