I am trying to use this to decrypt a dash media segment from a vod movie

i am using nodejs 18 this is the code i am using

`
keys = {
[row.vkid]:row.vkey
};

     const encrypted = fs.readFileSync(combinedLocation);

    mp4decrypt.decrypt(encrypted, keys).then(decrypted => {
         fs.writeFileSync('dec.mp4', decrypted)
    })

`

the media file does not play after decryption using vlc i get the following errors

faad warning: PCE shall be the first element in a frame

faad warning: Bitstream value not allowed by specification

I have tested the exact same media files kid and key using mp4decrypt running it as an spawned process and the output plays correctly it is only when using this modual i run into issues but there are no error messages or anything provided for failed decryption or anything so its really hard to tell what the issue is

hey same happened to one of my audio files, couldn't open the file and used faad.exe to repair the corrupt file and this popped up. were you able to fix the problem? Error: Bitstream value not allowed by specification
0% decoding test.m4a.
