Where are embedded cuepoints stored in HDS? The f4m or the frgaments?

[Tim Beynart]

I am packaging an f4v with embedded cuepoints with f4fpackager.  The cuepoints are preserved when I stream using HDS, but I am curious. Where is the cuepoint data stored? I do not see anything cuepoint-like in the f4m, so I am assuming the cuepoints are part of the fragments.

Yes they would be in f4f fragments.

Thanks! Is there any way to read the fragment data to verify cuepoints? Are the technical details of fragments documented anywhere?

I don't know whether there is detailed f4f doc - i'll see if there is anything of such kind in public domain and which can be shared.

You can however look at this document: http://www.adobe.com/products/httpdynamicstreaming/pdfs/httpdynamicstreaming_wp_ue.pdf

I am not sure whether it will work but what you can do is - copy the f4f fragment file, rename it to .mp4 , copy it to vod media folder and try to stream it back via RTMP with your client having data handler function to catch the cuepoints.

Thanks, I appreciate the response. I found info elsewhere that explained that the f4f files are, in fact, f4v. This clarifies things quite a bit.
