am 49fcd3cc: Fix an error caused by sample size value by order

    mOwner->beginBox("stsz");

    mOwner->writeInt32(0);  // version=0, flags=0

    if (mSamplesHaveSameSize) {

        List<uint32_t *>::iterator it = mSampleSizes.begin();

        mOwner->writeInt32((*it)[0]);  // default sample size

        CHECK(mCurrentSampleSizeArr != 0);

        mOwner->write(mCurrentSampleSizeArr, 4, 1);  // default sample size

    } else {

        mOwner->writeInt32(0);

    }
