FMLE and closed captioning

Hi.

We're streaming with FMLE 3.2 to Akamai HD CDN, and can't get closed captions to work, we can't see them in result stream from FMLE.

Does AMS 4.5 support closed captions at all? If so, can you please provide us with information about how closed captions should be encoded to stream them through FMLE?

We have succesfully grabbed line21 byte pairs (closed captions) from our capture source, so we know for sure they are present in source signal (v210).

Thanks in advance.
