mpp_dec_parser 和mpp_dec_hal 无法释放，导致内存泄漏

[HouLingLXH]

一下是我的初始化和释放代码： ` MppDecoder::~MppDecoder() { std::cout << "====析构==MppDecoder=" << std::endl; if (loop_data.packet) { mpp_packet_deinit(&loop_data.packet); loop_data.packet = NULL; } if (frame) { mpp_frame_deinit(&frame); frame = NULL; } if (mpp_ctx) { mpp_destroy(mpp_ctx); mpp_ctx = NULL; }

if (loop_data.frm_grp) {
    mpp_buffer_group_put(loop_data.frm_grp);
    loop_data.frm_grp = NULL;
}

}

int MppDecoder::Init(int video_type, int fps, void* userdata) { std::thread::id this_thread_id = std::this_thread::get_id(); // 获取本线程的ID std::cout << " MppDecoder::Init Thread ID = " << this_thread_id << std::endl;

MPP_RET ret         = MPP_OK;
this->userdata = userdata;
this->fps = fps;
this->last_frame_time_ms = 0;
if(video_type == 264) {
    mpp_type  = MPP_VIDEO_CodingAVC;
} else if (video_type == 265) {
    mpp_type  =MPP_VIDEO_CodingHEVC;
} else {
    LOGD("unsupport video_type %d", video_type);
    return -1;
}
LOGD("mpi_dec_test start ");
memset(&loop_data, 0, sizeof(loop_data));
LOGD("mpi_dec_test decoder test start mpp_type %d ", mpp_type);

MppDecCfg cfg       = NULL;

MppCtx mpp_ctx          = NULL;
ret = mpp_create(&mpp_ctx, &mpp_mpi);
if (MPP_OK != ret) {
    LOGD("mpp_create failed ");
    return 0;
}

ret = mpp_init(mpp_ctx, MPP_CTX_DEC, mpp_type);
if (ret) {
    LOGD("%p mpp_init failed ", mpp_ctx);
    return -1;
}

mpp_dec_cfg_init(&cfg);

/* get default config from decoder context */
ret = mpp_mpi->control(mpp_ctx, MPP_DEC_GET_CFG, cfg);
if (ret) {
    LOGD("%p failed to get decoder cfg ret %d ", mpp_ctx, ret);
    return -1;
}

/*
 * split_parse is to enable mpp internal frame spliter when the input
 * packet is not aplited into frames.
 */
ret = mpp_dec_cfg_set_u32(cfg, "base:split_parse", need_split);
if (ret) {
    LOGD("%p failed to set split_parse ret %d ", mpp_ctx, ret);
    return -1;
}

ret = mpp_mpi->control(mpp_ctx, MPP_DEC_SET_CFG, cfg);
if (ret) {
    LOGD("%p failed to set cfg %p ret %d ", mpp_ctx, cfg, ret);
    return -1;
}

mpp_dec_cfg_deinit(cfg);

loop_data.ctx            = mpp_ctx;
loop_data.mpi            = mpp_mpi;
loop_data.eos            = 0;
loop_data.packet_size    = packet_size;
loop_data.frame          = 0;
loop_data.frame_count    = 0;
return 1;

}`

析构之后，我在htop中查看，发现依然有很多mpp_dec_parser 和mpp_dec_hal 无法释放， 随着我多次反复创建于析构，他们会越来越多，内存也在不断被占用， 应该怎么办？
