Hi @IvanVitD ,
Thanks for posting in the Roku Community!
For more information about that channel’s features and functionality, you’ll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Please be noted that Closed captions features are available only when the service provider (e.g., Netflix, The Roku Channel, or Hulu) includes them with their content.
Here’s a link to our support page to find out more about the feature: How to enable closed captioning | Official Roku Support
Let me know if you have any other questions, and have a good day
Thanks for your replay.
I just want to say, that I’m a developer and I want to resolve such coding issue for closed captions for my channel.
So, not sure if it possible at all. Are there any system settings manipulations, CC config settings or similar for enabling such languages to be correct visible.
