Also got what I would think is video, all in sequence named "Fragments(video,format=f4m-f4f)Seg1-Frag1", etc, etc.
What I guess I figured out, I had been only downloading the keyframe files ONLY when using the AdobeHDS.php script. I dont know what to do with those keyframe files. It does stitch them together, and I get what I described as a video that looks like it is being fast forwarded. Any idea what to do with the keyframe, audio fragments, and video fragments???

This is starting to add up to something, but I don't know the solutions yet.
I recall that a few months back YouTube made a change to their video delivery that caused most downloaders to not be able to get the 1080p or 4K video without a muxing operation. Several of them began to charge money for the 1080p and 4K streams because they had to do the muxing on their own servers. JDownloader did it by using the client's PC, but requiring ffmpeg on the PC.
Perhaps what we have to do with these audio and video stream fragments is very similar to what the downloaders are doing with YouTube's highest quality videos. I just came across KSV's AdobeHDS.php yesterday, so I don't know if it can do this kind of merging or not or if this is just some kind of DRM issue. I'll try to get some time later to poke around it a bit.
