1、同时录制音频和视频 
try {
                    const audioRes = await audioStartRecording();
                    console.log('==startRecord 启动==init2===>', audioRes)
                    if (audioRes) {
                        await sleep(200);
                        const camaraRes = await videoStartRecording(timeoutCallback);
                        console.log('==startRecord 启动==init===>', audioRes, camaraRes)
                        if (camaraRes === RecordCallbackType.success) {
                            if (cameraFrame) {
                                extractFrame();
                            }
                            resolve({
                                audioRecordRes: audioRes,
                                videoRecordRes: camaraRes
                            })
                        } else {
                            console.log('==startRecord 失败===init=camaraRes=>' );
                            reject();
                        }
                    } else {


                        console.log('==startRecord 失败===init==audioRes==>', );
                        reject();
                    }


                } catch(e) {
                    console.log('==startRecord catch=====>', e)
                    reject(e)
                };
 1、启动音频录制
const videoStartRecording = (callback?: any) => new Promise((resolve, reject) => {
        console.log('videoStartRecording:启动开始录视频', recordPending.current);
        cameraContext.current = wx.createCameraContext();
        cameraContext.current?.startRecord({
            timeout: 300,
            success: () => {
                console.log('startRecord-video: 开始录制了！');
                resolve(RecordCallbackType.success);
            },
            timeoutCallback: () => {
                callback?.()
                reject(RecordCallbackType.timeoutCallback);
                console.log('startRecord-video: 录制超时了！');


            },
            fail: (data) => {
                console.log('startRecord-video: fail-录制失败了！', data);


            },
            complete: (data) => {
                if (data.errMsg === 'operateCamera:ok') {
                    resolve(RecordCallbackType.success);
                } else {
                    resolve(RecordCallbackType.complete);
                }
                console.log('startRecord-video: fail-complete-录制完成了！', data);


            }
        });
    })
3、启动视频录制
 const videoStartRecording = (callback?: any) => new Promise((resolve, reject) => {
        console.log('videoStartRecording:启动开始录视频', recordPending.current);
        cameraContext.current = wx.createCameraContext();
        cameraContext.current?.startRecord({
            timeout: 300,
            success: () => {
                console.log('startRecord-video: 开始录制了！');
                resolve(RecordCallbackType.success);
            },
            timeoutCallback: () => {
                callback?.()
                reject(RecordCallbackType.timeoutCallback);
                console.log('startRecord-video: 录制超时了！');


            },
            fail: (data) => {
                console.log('startRecord-video: fail-录制失败了！', data);


            },
            complete: (data) => {
                if (data.errMsg === 'operateCamera:ok') {
                    resolve(RecordCallbackType.success);
                } else {
                    resolve(RecordCallbackType.complete);
                }
                console.log('startRecord-video: fail-complete-录制完成了！', data);


            }
        });
    })

4、结束录制
// 兼容判断是否需要视频
            const allRes = Promise.all([audioStopRecording(), videoStopRecording()]);
            allRes.then(values => {
                if (cameraFrame) {
                    offExtractFrame();
                }
                recordPending.current = false;
                resolve({
                    audio: values[0],
                    video: values[1],
                    framePics: fileObj.current.framePics,
                    isIncludedVideo: !isCludedVideo,
                })
            }).catch(e => {
                    reject(e);
            });
