INFO:
-1- to see what tags are mapped so far run 'grep -n GST_TAG *.[ch]' into this folder.
+1- To see the list of tags current mapped:
+ http://webcvs.freedesktop.org/gstreamer/gst-plugins-bad/ext/metadata/metadata_mapping.htm?view=co
TODO:
3- Review the code (in order to move to gst-plugins-good)
4- Document how the plugin works (atchitecture and interaction beteween modules)
5- Improve the test application (to save also in png and to make it possible to set the metadata elements properties)
+6- Implement GDateTime support in GLib to be used by GStreamer (http://bugzilla.gnome.org/show_bug.cgi?id=50076)
+7- Use a standard GStreamer Data-Time type to map our Data-time tags
+8- Make the correct merge mode for multiple value tags (bag and seq) like dc:creator, ...
OPEN ISSUES:
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?)
-7- Add a helper function that convert from value to string. For example, aperture-size is 2.7 and the app wants to show "f/2.7", 'contrast' is a range and the app wants to show as "Normal", "Soft", "Hard". For the time being it is up to the APP to make this conversion.
