This file contains a list of things to be done as well some open issues (questions) related to design/implementation.
TODO:
1- Add individual tags IPTC and XMP (and more for EXIF)
2- Use GST_TYPE_FRACTION for Rational and SRational (metadataexif.c)
3- Get properties like 'width' and 'height' from caps
4- Review the code (in order to move to gst-plugins-good)
5- Document how the plugin works (atchitecture and interaction beteween modules)
OPEN ISSUES:
1- What is (How) the best way to delete some tag?
2- How to change metadata when the orignal image was modified.
ex: file.jpeg has XMP, then we do filesrc ! metadataparse ! jpegdec ! pngenc ! metadatamux ! files
is the metadata still valid? which fields are no valid anymore?
