#5948: Encrypted HLS stream lead to broken files

Summary of the bug:
How to reproduce:
Try to download an encrypted HLS stream with ffmpeg:
{{{
$ ffmpeg -i http://ipad-
streaming.cbsnews.com/media/mpx/2016/11/13/808012355634/1113_FullEpisodeTrump_1179719_5000/1113_FullEpisodeTrump_1179719_5000.m3u8
-c copy output.mp4
}}}
Both mpv and VLC says output.mp4 is 17 minutes long, while actually is 42
minutes long.
I've noticed that there are lots of warnings like this:
{{{
[mp4 @ 0x558344ee2a00] Non-monotonous DTS in output stream 0:0; previous:
93640192, current: 3795083; changing to 93640193. This may result in
incorrect timestamps in the output file.
}}}
Is it the main cause of wrong timestamps? If so how can I fix it?
