[FFmpeg-devel] [PATCH 07/21] libavcodec/metaenc: added an encoder/decoder for timed metadata

[erkki.seppala.ext at nokia.com]

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

This encoder is used primarily with ISO media files and basically
copies the data, while allowing the rest of the FFMPEG to refer
to the meta data with its identifiers.
