[FFmpeg-devel] [PATCH 13/21] libavformat/mov: basic support for identifying (and reading) timed metadata

[erkki.seppala.ext at nokia.com]

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

mov_codec_id is now able to set AVMEDIA_TYPE_DATA to the
st->codec->codec_type field when the input is of type
AVMEDIA_TYPE_DATA; previously it used AVMEDIA_TYPE_SUBTITLE as the
value to set in that case.
