  1. Currently struggling with decrypting a download from itvx my commands are as follows:
    mp4decrypt --key 2ab9cdcc7d8540a78a75f04c8816c702:702e61f28b4383edf 7aeed7364b74fd8 itvv.mp4 itvv_dec.mp4
    mp4decrypt --key 2ab9cdcc7d8540a78a75f04c8816c702:702e61f28b4383edf 7aeed7364b74fd8 itvv.m4a itva_dec.mp4
    ffmpeg -i itvv_dec.mp4 -i itva_dec.mp4 -c copy itv.mp4

    Which returns:
    ERROR: cannot open input file (itvv.mp4) -4

    Any help would be greatly appreciated

  2. Explorer > View > Tick 'File name extensions' box

    Check your filenames again - show screenshot

    And put your syntax within code tags to avoid gap showing in your key

    What did you use to download the files?
    in your above code, you've not paid attention to your input and output filenames
    second line
    Code:
     itvv.m4a itva_dec.mp4
    should be
    Code:
     itva.m4a itva_dec.m4a
    and your ffmpeg should be
    Code:
    ffmpeg -i itvv_dec.mp4 -i itva_dec.m4a -c copy itv.mp4

    Also, the error means it literally can not find a file named itvv.mp4
    So again, and very importantly, what it the initial download method you used? (yt/yt-dlp/n-m3u8xxxxxx/magic!!)

  4. Thank you both the file extension was incorrect (.mp4.mp4), after renaming correctly and retrying i've managed to decrypt the file

    I'm wondering why there are now two threads with the exact same error appearing.
