I want to insert wst teletext on vanc data using decklink protocol op47 . is there any support in existing casper cg or any patch available for that
It’s your lucky day! This got merged into master just two weeks ago.
Here is a link to a repo that demonstrates how to do this: GitHub - niklaspandersson/casparcg-vanc-demo · GitHub

op47 is not working correctly with french
The code in the casparcg server is agnostic to the content in the WST payload. When you encode your payload, you need to use the french G0 subset. See casparcg-vanc-demo/x26-encoder.js at main · niklaspandersson/casparcg-vanc-demo · GitHub (which has swedish and english G0 subsets, but uses the english subset for encoding, see rows 100-101). You can find the characters for french on wikipedia ( Teletext character set - Wikipedia ) for example.
