The full audio playback process includes creating an instance, setting the URI, playing audio, seeking to the playback position, setting the volume, pausing playback, obtaining track information, stopping playback, resetting resources, and releasing resources.
For details about the **src** media source input types supported by **AudioPlayer**, see the [src attribute](../reference/apis/js-apis-media.md#audioplayer_attributes).
During audio recording, audio signals are captured, encoded, and saved to files. You can specify parameters such as the sampling rate, number of audio channels, encoding format, encapsulation format, and file path for audio recording.
For details about the APIs used for audio recording, see [js-apis-media.md](../reference/apis/js-apis-media.md).
### Full-Process Scenario
The full audio recording process includes creating an instance, setting recording parameters, starting, pausing, resuming, and stopping recording, and releasing resources.
audioRecorder.on('prepare',()=>{// Set the 'prepare' event callback.
console.log('prepare success');
// The recording page is ready. You can click the Record button to start recording.
});
audioRecorder.on('start',()=>{// Set the 'start' event callback.
console.log('audio recorder start success');
// The Record button is changed to the pausable state.
});
audioRecorder.on('pause',()=>{// Set the 'pause' event callback.
console.log('audio recorder pause success');
// The Record button is changed to the recordable state.
});
audioRecorder.on('resume',()=>{// Set the 'resume' event callback.
console.log('audio recorder resume success');
// The Record button is changed to the pausable state.
});
audioRecorder.on('stop',()=>{// Set the 'stop' event callback.
console.log('audio recorder stop success');
});
audioRecorder.on('release',()=>{// Set the 'release' event callback.
console.log('audio recorder release success');
});
audioRecorder.on('reset',()=>{// Set the 'reset' event callback.
console.log('audio recorder reset success');
// You need to reset the recording parameters for another recording.
});
audioRecorder.on('error',(error)=>{// Set the 'error' event callback.
console.info(`audio error called, errName is ${error.name}`);
console.info(`audio error called, errCode is ${error.code}`);
console.info(`audio error called, errMessage is ${error.message}`);
});
}
// pathName indicates the passed recording file name, for example, 01.mp3. The generated file address is /storage/media/100/local/files/Movies/01.mp3.
// To use the media library, declare the following permissions: ohos.permission.MEDIA_LOCATION, ohos.permission.WRITE_MEDIA, and ohos.permission.READ_MEDIA.
uri:testFdNumber,// testFdNumber is generated by getFd.
location:{latitude:30,longitude:130},
}
audioRecorder.prepare(audioRecorderConfig);
// 4. Start recording.
audioRecorder.start();// The start method can be called to trigger the 'start' event callback only after the 'prepare' event callback is complete.
// 5. Pause recording.
audioRecorder.pause();// The pause method can be called to trigger the 'pause' event callback only after the 'start' event callback is complete.
// 6. Resume recording.
audioRecorder.resume();// The resume method can be called to trigger the 'resume' event callback only after the 'pause' event callback is complete.
// 7. Stop recording.
audioRecorder.stop();// The stop method can be called to trigger the 'stop' event callback only after the 'start' or 'resume' event callback is complete.
// 8. Reset recording.
audioRecorder.reset();// The prepare method can be called for another recording only after the 'reset' event callback is complete.
// 9. Release resources.
audioRecorder.release();// The AudioRecorder resource is destroyed.
audioRecorder=undefined;
```
### Normal Recording Scenario
Unlike the full-process scenario, the normal recording scenario does not include the process of pausing and resuming recording.
audioRecorder.on('prepare',()=>{// Set the 'prepare' event callback.
console.log('prepare success');
// The recording page is ready. You can click the Record button to start recording.
});
audioRecorder.on('start',()=>{// Set the 'start' event callback.
console.log('audio recorder start success');
// The Record button is changed to the pausable state.
});
audioRecorder.on('stop',()=>{// Set the 'stop' event callback.
console.log('audio recorder stop success');
});
audioRecorder.on('release',()=>{// Set the 'release' event callback.
console.log('audio recorder release success');
});
}
// pathName indicates the passed recording file name, for example, 01.mp3. The generated file address is /storage/media/100/local/files/Movies/01.mp3.
// To use the media library, declare the following permissions: ohos.permission.MEDIA_LOCATION, ohos.permission.WRITE_MEDIA, and ohos.permission.READ_MEDIA.
uri:testFdNumber,// testFdNumber is generated by getFd.
location:{latitude:30,longitude:130},
}
audioRecorder.prepare(audioRecorderConfig)
// 4. Start recording.
audioRecorder.start();// The start method can be called to trigger the 'start' event callback only after the 'prepare' event callback is complete.
// 5. Stop recording.
audioRecorder.stop();// The stop method can be called to trigger the 'stop' event callback only after the 'start' or 'resume' event callback is complete.
// 6. Release resources.
audioRecorder.release();// The AudioRecorder resource is destroyed.
During video recording, audio and video signals are captured, encoded, and saved to files. You can specify parameters such as the encoding format, encapsulation format, and file path for video recording.
For details about the APIs used for video recording, see [js-apis-media.md](../reference/apis/js-apis-media.md).
### Full-Process Scenario
The full video recording process includes creating an instance, setting recording parameters, recording video, pausing, resuming, and stopping recording, and releasing resources.
// pathName indicates the passed recording file name, for example, 01.mp4. The generated file address is /storage/media/100/local/files/Movies/01.mp4.
// To use the media library, declare the following permissions: ohos.permission.MEDIA_LOCATION, ohos.permission.WRITE_MEDIA, and ohos.permission.READ_MEDIA.
// Video recording depends on camera-related interfaces. The following operations can be performed only after the video output start interface is invoked.
// Start video recording.
awaitvideoRecorder.start().then(()=>{
console.info('start success');
},failureCallback).catch(catchCallback);
// Pause video playback before the video output stop interface is invoked.
awaitvideoRecorder.pause().then(()=>{
console.info('pause success');
},failureCallback).catch(catchCallback);
// Resume video playback after the video output start interface is invoked.
awaitvideoRecorder.resume().then(()=>{
console.info('resume success');
},failureCallback).catch(catchCallback);
// Stop video recording after the video output stop interface is invoked.
awaitvideoRecorder.stop().then(()=>{
console.info('stop success');
},failureCallback).catch(catchCallback);
// Reset the recording configuration.
awaitvideoRecorder.reset().then(()=>{
console.info('reset success');
},failureCallback).catch(catchCallback);
// Release the video recording resources and camera object resources.
