Summary0022068: Some M4A files cannot be parsed and scan fails
DescriptionUser has M4A files where MM fails to parse and scan. It seems the files have malformed metadata. Our parser is now too strict - if the malformed part is only in the metadata (inside moov.udta.meta.ilst) and the rest of the file seems to be fine, we should skip the invalid data and parse the rest of the file. Also fix the metadata part when saving tags (i.e. remove the malformed metadata).
Additional InformationTicket 16782
TagsNo tags attached.
Fixed in build3402

 Fixed in build 3402. MM now tries to skip wrong data in moov.udta.meta.ilst and continue parsing. And in case the rest of the file is ok, it is scanned and metadata header fixed during first tagging.
