Embedded Subtitles selected but not showing up

I have .mp4 videos with embedded subtitles. They show properly when I play the video with QuickTime (see attachment). However they don’t show up in Infuse (iOS & tvOS).
I can see the subtitle is selected in video settings as Track2, though. Why do you think Infuse can’t display them?

This may contain a subtitle type that Infuse doesn’t support.

If you are able to send in a sample, we’d love to take a deeper look at this.

Thank you. Just uploaded a sample video (subtitle-issue-sample.mp4). Hope it appears on your end?

Got it, thanks!

This subtitle format (EIA-608) isn’t supported right now, but is on our list to add for an upcoming version.
