Original commit message from CVS: * gst-libs/gst/tag/id3v2.c: (id3demux_add_id3v2_frame_blob_to_taglist): Extract frames for ID3v2 versions prior to ID3v2.3.0 properly as well, and add the version to the blob's buffer caps, since that information will be needed for deserialisation later on (#348644).
