我这边调用释放组内存会打印错误信息提示有数据未释放：

我这边MppBuffer申请流程是这样的：
//申请组
ret = mpp_buffer_group_get_internal(&p_encoder_handle->buf_group, MPP_BUFFER_TYPE_DRM | MPP_BUFFER_FLAGS_CACHABLE);
//申请frame buffer
ret = mpp_buffer_get(p_encoder_handle->buf_group, &p_encoder_handle->frame_buffer, p_encoder_handle->frame_size);
//申请packet buffer
ret = mpp_buffer_get(p_encoder_handle->buf_group, &p_encoder_handle->packet_buffer, p_encoder_handle->frame_size);
释放流程是这样的：
if (p_encoder_handle->ctx) {
p_encoder_handle->mpi->reset(p_encoder_handle->ctx);
mpp_destroy(p_encoder_handle->ctx);
p_encoder_handle->ctx = NULL;
}

if (p_encoder_handle->frame_buffer) {
    mpp_buffer_put(p_encoder_handle->frame_buffer);
    p_encoder_handle->frame_buffer = NULL;
}

if (p_encoder_handle->packet_buffer) {
    mpp_buffer_put(p_encoder_handle->packet_buffer);
    p_encoder_handle->packet_buffer = NULL;
}

if (p_encoder_handle->buf_group) {
    mpp_buffer_group_put(p_encoder_handle->buf_group);
    p_encoder_handle->buf_group = NULL;
}

我这个流程是完成按照demo和手册的说明进行释放的，但是就是会打印这些信息，请大佬帮忙看看有没有问题
