Android ndk 我怎样才能摧毁playerObj？

我正在尝试创建引擎和输出组合：

// create engine
this->res = slCreateEngine(&this->engineObject, 0, NULL, 0, NULL, NULL);
if (SL_RESULT_SUCCESS != this->res)
{
    LOGI("Can't Create Engine.");
    this->Free();
    return;
}
this->res = (*this->engineObject)->Realize(this->engineObject, SL_BOOLEAN_FALSE);
if (SL_RESULT_SUCCESS != this->res)
{
    LOGI("Can't Realize Engine.");
    this->Free();
    return;
}
this->res = (*this->engineObject)->GetInterface(this->engineObject, SL_IID_ENGINE, &this->engineEngine);
if (SL_RESULT_SUCCESS != this->res)
{
    LOGI("Can't GetInterface Engine.");
    this->Free();
    return;
}

// create output mix
this->res = (*this->engineEngine)->CreateOutputMix(this->engineEngine, &this->outputmixObject, 0, NULL, NULL);
if (SL_RESULT_SUCCESS != this->res)
{
    LOGI("Can't Create Output Mix.");
    this->Free();
    return;
}
this->res = (*this->outputmixObject)->Realize(this->outputmixObject, SL_BOOLEAN_FALSE);
if (SL_RESULT_SUCCESS != this->res)
{
    LOGI("Can't Realize Output Mix.");
    this->Free();
    return;
}

这是成功的

从IceCast开始播放mp3流 （例如“”）：

filename=“”

LogCat开始打印错误消息…：

E/libOpenSLES（16432）：媒体缓冲更新-491520000%<0 E/libOpenSLES（16432）：媒体缓冲更新-655360000%<0 E/libOpenSLES（16432）：媒体缓冲更新-819200000%<0

但是小溪在玩！ 好吧，我试着停止玩：

this->res = (*this->playerInterface)->SetPlayState(this->playerInterface, SL_PLAYSTATE_STOPPED);
if (SL_RESULT_SUCCESS != this->res)
    LOGI("Can't Set Play State \"SL_PLAYSTATE_STOPPED\".");

好的！游戏确实停止了，但玩家继续下载流。

所以我试着摧毁PlayerObj：

(*this->player)->Destroy(this->player);

LogCat打印错误消息：

A//system/bin/app_进程（16690）：检测到堆栈损坏：中止

和应用程序进程终止。

怎么了？

在“设置循环”之后，我开始播放：

this->res=（*this->playerInterface）->设置播放状态（this->playerInterface，SL_playerState_playing）问题已解决，错误在不同的位置！
(*this->player)->Destroy(this->player);
