Hi,
I use following code to to add movie's meta data,
when the key is kQTMetaDataCommonKeyDisplayName, it
works, but when it is kQTMetaDataCommonKeyInformation
or kQTMetaDataCommonKeyDescription, it does not show
up in the QuicktimePro's movie properties window, why?
thanks .
AC.
QTMetaDataRef theMetaData = NULL;
OSType key =
kQTMetaDataCommonKeyInformation;
OSErr err;
Movie movie;
movie = [Qmovie quickTimeMovie];
err = QTCopyMovieMetaData(movie, &theMetaData);
if (noErr == err)
{
char *Mark = "test text";
QTMetaDataAddItem(theMetaData,
kQTMetaDataStorageFormatiTunes,
kQTMetaDataKeyFormatCommon, (const UInt8 *)&key,
sizeof(key), Mark, 10, kQTMetaDataTypeUTF8, NULL);
if ([Qmovie canUpdateMovieFile])
[Qmovie updateMovieFile];
QTMetaDataRelease(theMetaData);
}
