 recently a big adult cam site changed their hls manifest.
 since then the streams dont play correctly anymore in kodi.
 with ffmpeg/ffplay i get stutter too while using the following command
 line.

 ffmpeg.exe -i http://xxxxx.m3u8 test.mp4 // not sure if iam allowed to
 post the url to the stream...

 as far as i can tell, they have two different manifest...sometimes there
 are only 3 chunks in the playlist

 What you were trying to accomplish?
 -> play the stream without stuttering/skipping/buffering

 The problem you encountered?
 -> skipping video, constant buffering within kodi making the streams
 unwatchable

 The exact command line you were using
 -> ffmpeg.exe --report http://xxxxxxxxxxxxx.m3u8 option1.mp4
 -> ffmpeg version N-82225-gb4e9252 Copyright (c) 2000-2016 the FFmpeg
 developers

 maybe you guys have an idea why this is happening.
 thanks in advance
