Playing a DRM m3u8 file in FFMPEG

Question

I'm attempting to play a Adobe Access DRM protected file in FFMPEG. Here is an example of the type of file I am trying to play: http://drmtest2.adobe.com/Content/FAXS4/Anonymous_REMOTE/sample.mp4.m3u8

This file works perfectly (as expected) in Adobe's DRM test player (http://drmtest2.adobe.com:8080/AccessPlayer/player.html) but not in ffmpeg. Here is the log:

ffmpeg -protocol_whitelist "file,http,https,tcp,tls,crypto" -i http://drmtest2.adobe.com/Content/FAXS4/Anonymous_REMOTE/sample.mp4.m3u8 -c copy output.ts

I have a strong suspicion that it isn't possible to play these types of files within FFmpeg, if not is there an alternate (even Adobe provided) player that I can use?
