因为没有 mvex atom

    // Read declaration of track fragments in the Moov box.
    ContainerAtom mvex = moov.getContainerAtomOfType(Atom.TYPE_mvex);
    SparseArray<DefaultSampleValues> defaultSampleValuesArray = new SparseArray<>();
    long duration = C.TIME_UNSET;
    int mvexChildrenSize = mvex.leafChildren.size();
    for (int i = 0; i < mvexChildrenSize; i++) {
      Atom.LeafAtom atom = mvex.leafChildren.get(i);
      if (atom.type == Atom.TYPE_trex) {
        Pair<Integer, DefaultSampleValues> trexData = parseTrex(atom.data);
        defaultSampleValuesArray.put(trexData.first, trexData.second);
      } else if (atom.type == Atom.TYPE_mehd) {
