    Talking how to modify the chunklist.m3u8

    Hello,

    I am using Wowza server 4.1.0. This is how the chunklist.m3u8 file looks like when I am not using any token authentication on the stream:

    #EXTM3U
    #EXT-X-VERSION:3
    #EXT-X-ALLOW-CACHE:NO
    #EXT-X-TARGETDURATION:12
    #EXT-X-MEDIA-SEQUENCE:2013
    #EXTINF:9.6,
    media_2013.ts
    #EXTINF:12.0,
    media_2014.ts
    #EXTINF:9.6,
    media_2015.ts
    #EXTINF:9.6,
    media_2016.ts
    #EXTINF:9.6,
    media_2017.ts
    #EXTINF:9.6,
    media_2018.ts
    #EXTINF:9.6,
    media_2019.ts

    When I apply the token authentication (the token is applied on the CDN part) the chunklist.m3u8 looks like:
    #EXTM3U
    #EXT-X-VERSION:3
    #EXT-X-ALLOW-CACHE:NO
    #EXT-X-TARGETDURATION:12
    #EXT-X-MEDIA-SEQUENCE:149
    #EXTINF:9.6,

    My question is: Is there any possibility to take this "_w144867311" off and make the .TS fragment looks like this: i.e
    #EXTINF:9.6,
    media_158.ts?__token__=exp%3D1423671289%7Eacl%3D%2F*%2Ftesttoken%2F*%7Ehmac%3Db456589a1892b3bbd66d35 b0d163b7c2c5cf50c746454482bb49664c844c5d56

    ??
    Can someone advise me please?
