mp4decrypt-buffer

Take CENC media and decrypt it using Bento4's mp4decrypt and Node Buffers. Perfect for small files like DASH segments.

Example

const mp4decrypt = require('mp4decrypt-buffer')

const keys = {
  'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa': 'bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb'
}

const encrypted = fs.readFileSync('enc.m4s')
mp4decrypt.decrypt(encrypted, keys).then(decrypted => {
  fs.writeFileSync('dec.mp4', decrypted)
})
