Bug 120335 – [Windows] some track language tags are not recognized

• Component: Media
• Status: RESOLVED FIXED

[Brent Fulgham]

Port the Mac-only changes from Bug 119643 (landed in https://trac.webkit.org/r154527) to Windows.

Specifically:
If a movie's language code is stored as a QuickTime 5-bit packed code there aren't enough bits for a full RFC 4646 language tag. The AVFoundation API we use returns NULL in this case, so we have to try another to see if we can get the ISO 639-2/T language code.

This should be:

    if (primaryAudioTrackLanguage != languageOfPrimaryAudioTrack())
        characteristicsChanged();
