[FFmpeg-devel] [PATCH 11/21] libavformat/movenc, isom: support metadata in mp4 files

[erkki.seppala.ext at nokia.com]

From: Erkki Seppälä <erkki.seppala.ext at nokia.com>

This involves adding a new tag to the ff_mp4_obj_type table as well as
modifying mp4_get_codec_tag to return 'meta' for AV_CODEC_ID_META.
