This file contains a list of things to be done as well some open issues (questions) related to design/implementation.
|
|
|
|
INFO:
|
|
|
|
1- to see what tags are mapped so far run 'grep -n GST_TAG *.[ch]' into this folder.
|
|
|
|
TODO:
|
|
|
|
1- Add more individual tags to XMP, EXIF and IPTC
|
|
2- Get properties like 'width' and 'height' from caps
|
|
3- Review the code (in order to move to gst-plugins-good)
|
|
4- 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?
|
|
3- In EXIF, how to make sure we are compliant with the specification when adding some tag? For example, we are not considerinb what are mandatory (or optional) IFDs for tags.
|
|
4- Add GST_TYPE_FRACTION support for GStreamer TAGS
|
|
5- currently, in JPEG files, if there is a Photoshop segment, everything inside it but IPTC will be lost. From the point of view of implementation it is easy, but I still don't now how to solve from the point of view of "designing". Anyway I think it is not so important.
|
|
6- language is not considered in XMP (How to do it with GStreamer?)
|
|
