Hi There is there jpeg Support for the Input image?

I'd also like to see this. Since https://github.com/AOMediaCodec/libavif supports encoding from JPEG, I'm not sure why this implementation of it wouldn't also support them.

To support JPEG, we also have to working with JPEG specification, such as progressive JPEG, EXIF, XMP, and so on. We would like to work on supporting libaom's latest features and API to achieve better image quality, rather than supporting other image format.

While libavif is a 'easy to use' library, cavif aims to be 'difficult to use, but it let us generate better quality AVIF image' program. Note that cavif does not use libavif, which hides the libaom's API.

However, any pull request to support JPEG is always welcome!
