Closed Captioning with Adobe Media Server

We've successfully made the jump to using the Adobe Media Server 4.5 to provide video to both Desktop computers and iOS devices, (HLS and HDS).  Very exciting.

However, with increasing requirements to provide closed captioning for accessibility, we need to be able to provide closed captioning for our videos displaying on iOS and in the Flash player.

What is the best approach to provide closed captioning using these new FMS technologies?

I have cc working on FMS 4.5 for everything but the iPhone.  The iPhone player will not support CC.  Only Apple can fix this.  I'm using a custom deployment of OSMF with TTML formatted cc files for video on demand.  I'm not using RTMP because of firewall/support issues.  For HTML5 I'm using the LeanBackPlayer with SRT formatted cc files.  We built a JAVA exe that builds the TTML and SRT cc files from delimited text files or Excel.  We auto built cross server authentication between ASP.NET/IIS and Apache.  Getting everyting setup and working was pretty difficult.  Far more difficult than anticipated. 

It can be done with 4.5.

Thanks, David ... I'm hoping to find a player that understands the output from Adobe's Broadcast SDK 3.0, which processes SEI from H264 and adds CC (not sure what format, yet) to the fragments in the .f4f files.

When you figure it out be sure to post the solution.  I'm also interested in this.

Hi,

AMS 5 is coming up with exciting release of delivery closed captions on HLS /HDS/RTMP.

However for customers still on FMS 4.5, we have guidlines for content publisher or content makers to have closed caption compatiable messages inside data itself required for HDS/HLS/RTMP.

Wait for sometime for the documents to go live.

Thanks

Assuming we're using AMS5, what's the best way of actually delivering a captioned video stream to the server?  As far as I can tell, FMLE strips all 608/708 data out of the stream.

I've got AMS 5.0.1 installed. How do I enable CC display in the player? Are there any sample files which contain CC?
