HLS Embedded Caption Support

I'm testing out the player and liking what I am seeing so far. Currently I have hit a road block that is deal breaking for me. I'm doing HLS live streaming with embedded CC608/708 Captions in the video. Does the viblast player support embedded caption decoding if so how can implement it. integrating with video JS for this is acceptable to me if this is an option.

HI Aaron,


At the moment Viblast Player doesn't support embedded CC608/708 captions.

We will put this in our pipeline and will let you know once it is ready.

We can't give you an ETA.

By having HLS support for CC608/708 captions, we would be able to natively support live closed captions. A number of our clients have the ability to send caption data from a transcription service/application into their encoder and have it then pass through into the HLS output from a transcoder on our side.


Without the ability to have the HLS playback engine recognize and expose that data, we have a hard time being able to provide live closed captioning for clients. Our only other real option then is to bake the captions into the video feed being delivered, but that removes the ability to have them be 'closed' captions.


Something that makes live closed captioning more prevalent now than it used to be is that America's National Public Radio organization and its affiliates are being pressured to fully comply with accessibility requirements that exist here in the U.S. Having CC608/708 support in Viblast not only would allow us to support closed captioning in live video content, but live audio as well. 

Hello Robert,


There was lack of demand for embedded captions support.

How the CC608/708 captions can help you especially with live stream?


Has there been any development on that idea in the passed 3 years? I have not seen anything.


If decoded information could be emitted as an event available for binding, this would substantially increase our ability to provide HLS-based video playback for organizations that need to satisfy various compliance issues regarding live stream accessibility.
