Hi All,

I would like to add some new generic GST_TAGs to the GStreamer in order to make
it possible to add proper metadata for image capturing (could also be used for
other things), for example add EXIF metadata to JPEG images.

To start, I have the following metadata's in mind:

1- provided by the application to the pipeline:

GST_TAG_SOURCE_MAKE
GST_TAG_SOURCE_MODEL

* could also be provided by source element, e.g. videotestsrc sends "GStreamer
videotestsrc", the cdda-reader could put the used cd-drive name there, v4l2src
sends the card-name and so on (some elements probably only set _MODEL).

GST_TAG_DEVICE_SERIAL
GST_TAG_SOFTWARE      // g_get_application_name()

2- provided by the source elements

GST_TAG_TIME  // there is already a GST_TAG_DATE but 'time'.
// What about create tags for creation and modification instead of just one
date and time?
