CEA-708
WEBVTT

[Ood-Tsen]

Do you have any test link for cea-608 , cea-708 or webvtt ?

[andudo]

@Ood-Tsen i don't have any test links right now. are you asking because you need one, or you would like to help with providing one (any test resources you can share would be much appreciated)?

[andudo]

@Ood-Tsen just in case you're still looking for test links. apple's default examples have CEA-608 and WebVTT.
