  • how to use ffmpeg encrypt AES-128 HLS m3u8 playlist ? [duplicate]

    22 décembre 2015, par jason

    This question already has an answer here :

    I use the ffmpeg -i fighter.mp4 -hls_time 10 stream.m3u8 to crated a m3u8 file.
    But there’s not #EXT-X-KEY info in the m3u8 file.
    What should I do to add key in the HLS playlist ?

  • Play a HLS live m3u8 playlist, with expiring key

    3 novembre 2016, par maxgalbu

    I’m trying to play an HLS url from the NBA servers, from Kodi (which is using ffmpeg).

    http://nlds16.cdnak.neulion.com/nlds/nba/nba247/as/live/ipad_20161102200000_003000.mp4.m3u8?hdnea=expires%3D1478128277%7Eaccess%3D%2Fnlds%2Fnba%2Fnba247%2Fas%2Flive%2F*%7Emd5%3Dmd5&nltid=nba&nltdt=6&nltnt=1&uid=2312934

    It’s behind a login, so you won’t be able to play it.

    This url has an expiring encryption key, and if I try to play that playlist from the NBA website, I can see that the player, every 5 seconds, does a request for the same playlist, and every time it downloads a new encryption key. If i play it with ffmpeg, there’s only one request, and the key eventually expires interrupting the streaming. Is it possible to do the same with ffmpeg ?

  • HlS playlist skip files with ffmpeg

    29 janvier, par tamirg

    I simply downloaded 5 mp3 files from here :
https://samplelib.com/sample-mp3.html

    


    which means i have :

    


    sample-3s.mp3
sample-6s.mp3
sample-9s.mp3
sample-12s.mp3
sample-15s.mp3


    


    and then i create a simple hls playlist sample.m3u8 :

    


    #EXTM3U
#EXT-X-TARGETDURATION:20
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:3.0,
sample-3s.mp3
#EXTINF:6.0,
sample-6s.mp3
#EXTINF:9.0,
sample-9s.mp3
#EXTINF:12.0,
sample-12s.mp3
#EXTINF:15.0,
sample-15s.mp3


    


    But when i play this playlist :

    


    ffplay sample.m3u8


    


    i get :

    It starts playing from the file sample-9s, and not sample-3s. So it skips the first two files.
Why does it happen ?
