    You need to build your own.
    If you need help with that, please start a new thread. It would be wrong to continue here.

    I need to compile your source from
    or github master:

    I have the problem already, that I cannot grep for the necessary option "cenc_decryption_key" in this master build nor in the linked commit on
    referencing this commit:

    in the master it occours in libavformat/dashdec.c but only as an calling argument for a function, not as a parsed keyword.

    So I am looking for:
    For my Ubuntu 22.04 with the exact same configure options and dependencies as did it for windows builds! What is the exact configure sets?

    At the moment I have problems accessing the cenc_decryption_key option. I see it in the code but I am not able to access it like:

    $ ffmpeg -cenc_decryption_key f41bfd29971559e77def5d7c68679d46 -headers "Cookie:CloudFront-Policy=eyJT[..]e9XX0_; CloudFront-Signature=n[..]ZNfi~P4[..]mb~Hbkq73-hh[..]-yNEko~Ylt[..]1A__; CloudFront-Key-Pair-Id=K1JM[..]73; auth_id=12[..]05; sess=ipk[..]qk
    User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/119.0" -i "[..]1yt.mpd" -codec copy "/home/xx/Desktop/yy/zz/rr/ff/bb/dd/Videos/0hg[..]1yt_source.mp4"
    But in fact it seems to work on windows! It is called from a github project, written in C#. It works mostly perfect, but it refuses to load encrypted DRM videos, for example for the missing option cenc_decryyption_key!

    When I call:

    $ ffmpeg -cenc_decryption_key abcdefabcdefabcdabcdefabcdefabcd

    Unrecognized option 'cenc_decryption_key'.
    Error splitting the argument list: Option not found

    What really wonders me, that this option cannot be accessed, I must have overseen something! Is the calling from windows terminal different regarding options? For the string literals I assume that maybe my bash acts differently then windwos terminal.... regarding line ends, escape sequences or double quotes and single quotes...

    Thanks for any hints, which could help dissolve this (complex?) matter!
