    I've made an educated guess on how to continue: simply skip the
    package,
    and it seems to work smoothly:

      <br>
      thanks for sharing. The issue under the hood is seems to be that
      avcodec_decode_audio4() returns with error "[mp2 @ 0x9e527c0]
      Header missing". How to continue in such a case?
      <br>

      Thanks and regards,
