Steps to reproduce:

  1. Create folder "ąćęłńóśżź" as a working folder.
  2. Enter:
    N_m3u8DL-RE.exe https://vcze131.cda.pl/1670449/1670449.mpd?uid=5983825771 --key 65353534306438366535346135346161:39303439626631336363393537303934 -M format=mkv
  3. Output mp4 isn't decrypted.

With --use-shaka-packager file is decrypted correctly.

You may be confusing Bento4 with some other tool. There is no such program as N_m3u8DL-RE.exe that is part of Bento4.

N_m3u8DL-RE.exe uses mp4decrypt to decrypt a video.

I have no idea how exactly N_m3u8DL-RE.exe invokes mp4decrypt, so it's hard to tell what the issue may be. Can you show what exact mp4decrypt command line is being used, and what its inputs are?

For me it's impossible because I don't know how. If I get a version of mp4decrypt that allows this, I can send it. Maybe -- Instead of mp4decrypt, I would substitute another application that would display the command line.

It looks like N_m3u8DL has this option:
--log-level <DEBUG|ERROR|INFO|OFF|WARN>
Can you try running with --log-level DEBUG, it should print out the mp4decrypt args when executing (see: https://github.com/nilaoda/N_m3u8DL-RE/blob/8fdb6bc90ba128b91bff32d32ed6152f88584374/src/N_m3u8DL-RE/Util/MP4DecryptUtil.cs#L81)

The resulting file was not decrypted.
