Description
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?

Environment:
