+# OpenSL ES Audio Playback Development
+
+ 
+
+## When to Use
+
+You can use OpenSL ES to develop the audio playback function in OpenHarmony. Currently, only some [OpenSL ES APIs](https://gitee.com/openharmony/third_party_opensles/blob/master/api/1.0.1/OpenSLES.h) are implemented. If an API that has not been implemented is called, **SL_RESULT_FEATURE_UNSUPPORTED** will be returned.
+
+ 
+
+## How to Develop
+
+To use OpenSL ES to develop the audio playback function in OpenHarmony, perform the following steps:
+
+1. Add the header files.
+
+    ```c++
+    #include <OpenSLES.h>
+    #include <OpenSLES_OpenHarmony.h>
+    #include <OpenSLES_Platform.h>
+    ```
+
+    
+
+2. Use the **slCreateEngine** API to obtain an **engine** instance.
+
+    ```c++
+    SLObjectItf engineObject = nullptr;
+    slCreateEngine(&engineObject, 0, nullptr, 0, nullptr, nullptr);
+    (*engineObject)->Realize(engineObject, SL_BOOLEAN_FALSE);
+    ```
+
+    
+
+3. Obtain the **engineEngine** instance of the **SL_IID_ENGINE** interface.
+
+    ```c++
+    SLEngineItf engineEngine = nullptr;
+    (*engineObject)->GetInterface(engineObject, SL_IID_ENGINE, &engineEngine);
+    ```
+
+    
+
+4. Configure the player and create an **AudioPlayer** instance.
+
+    ```c++
+    SLDataLocator_BufferQueue slBufferQueue = {
+        SL_DATALOCATOR_BUFFERQUEUE,
+        0
+    };
+    
+    // Configure the parameters based on the audio file format.
+    SLDataFormat_PCM pcmFormat = {
+        SL_DATAFORMAT_PCM,
+        2,
+        48000,
+        16,
+        0,
+        0,
+        0
+    };
+    SLDataSource slSource = {&slBufferQueue, &pcmFormat};
+    
+    SLObjectItf pcmPlayerObject = nullptr;
+    (*engineEngine)->CreateAudioPlayer(engineEngine, &pcmPlayerObject, &slSource, null, 0, nullptr, nullptr);
+    (*pcmPlayerObject)->Realize(pcmPlayerObject, SL_BOOLEAN_FALSE);
+    ```
+
+    
+
+5. Obtain the **bufferQueueItf** instance of the **SL_IID_OH_BUFFERQUEUE** interface.
+
+    ```
+    SLOHBufferQueueItf bufferQueueItf;
+    (*pcmPlayerObject)->GetInterface(pcmPlayerObject, SL_IID_OH_BUFFERQUEUE, &bufferQueueItf);
+    ```
+
+    
+
+6. Open an audio file and register the **BufferQueueCallback** function.
+
+    ```c++
+    FILE *wavFile_ = nullptr;
+    
+    static void BuqqerQueueCallback (SLOHBufferQueueItf bufferQueueItf, void *pContext, SLuint32 size)
+    {
+        FILE *wavFile = (FILE *)pContext;
+        if (!feof(wavFile)) {
+            SLuint8 *buffer = nullptr;
+            SLuint32 pSize = 0;
+            (*bufferQueueItf)->GetBuffer(bufferQueueItf, &buffer, pSize);
+            // Read data from the file.
+            fread(buffer, 1, size, wavFile);
+            (*bufferQueueItf)->Enqueue(bufferQueueItf, buffer, size);
+        }
+        return;
+    }
+    
+    // Set wavFile_ to the descriptor of the file to be played.
+    wavFile_ = fopen(path, "rb");
+    (*bufferQueueItf)->RegisterCallback(bufferQueueItf, BuqqerQueueCallback, wavFile_);
+    ```
+
+    
+
+7. Obtain the **playItf** instance of the **SL_PLAYSTATE_PLAYING** interface and start playback.
+
+    ```c++
+    SLPlayItf playItf = nullptr;
+    (*pcmPlayerObject)->GetInterface(pcmPlayerObject, SL_IID_PLAY, &playItf);
+    (*playItf)->SetPlayState(playItf, SL_PLAYSTATE_PLAYING);
+    ```
+
+    
+
+8. Stop audio playback.
+
+    ```c++
+    (*playItf)->SetPlayState(playItf, SL_PLAYSTATE_STOPPED);
+    (*pcmPlayerObject)->Destroy(pcmPlayerObject);
+    (*engineObject)->Destroy(engineObject);
+    ```
