Livestreaming Audio & Video
Closed Captioning for Livestreaming events is still a WCAG AA requirement (separate than the WCAG Guideline for recorded video). So, it’s is recommended that this is provided.
This service is pretty expensive, since you need to have someone basically typing in the closed captioning during any live feed. This would generally be the responsibility of the organization doing the live feed. Also, when you post the recording of the live video, then formal closed captioning would generally be done instead of the transcript used during the live event as there can be typos and mistakes.
Closed Captioning is recommended on both livestreaming and recorded video, but the WCAG 2.0 Guidelines for each scenario are different.
