What solution (free or paid) for closed caption in live stream with Wowza?
There’s no difference in Closed Captioning support between the free (trial) or paid version. The free version is limited to 30 days of use and has a few other limitations - see https://www.wowza.com/pricing/trial. But Closed Captioning works in both.
Lots of useful information about Closed Captioning in Wowza Streaming Engine is found here: https://www.wowza.com/docs/about-closed-captioning-in-wowza-streaming-engine and related articles (see menu on the left of that page)
I see, but the what application/software I do for make legends/closed caption in live stream?
