Embedded subtitle can not work

[lintw]

When I pull to commit id 1447ac941b1fea318ac357d9706ba34edb0316c4 on git https://code.videolan.org/videolan/VLCKit.git, [branch 3.0], [Tag 3.3.10], build MobileVLCKit.framework manually.
Video embedded subtitle cannot work.

But embedded subtitle is work on VLC iOS release version 3.2.8.

Is the commit sync as version VLC-iOS-3.2.8 ?
If not, could you tell which commit should I pull.
Thanks in advance.
