true rollup 608 closed captions
I'd like to know if, when JWPlayer (presumably the Premium version) detects CEA-608 closed caption data embedded in an HLS stream, it will preserve/display true rollup-style captions, obeying rollup depth commands, etc. My setup will be Wowza transcoding MPEG-2 with 608/708 data to HLS, and funneling to JWPlayer. I've seen plenty of examples of rollup captions being displayed as single-line pop-on captions, but this is neither a good representation (since the on-screen time of the single-line pop-on caption is typically much too short to read comfortably, nor does it satisfy FCC requirements.
Thanks.
