CameraContext.startRecord(Object object)timeoutnumber30否录制时长上限，单位为秒，最长不能超过 5 分钟 实际测试发现正常录制视频在115s，超过120s回调函数均不回调，文档显示支持5分钟以内视频录制。 startRecord() { let that = this; let recordTime = 115; let totalInterval = recordTime * 1000; let totalTime = 0; let intervalId; this.ctx.startRecord({ timeout: recordTime, timeoutCallback: () => { console.log('=========>timeoutCallback') clearInterval(intervalId); that.stopRecord(); }, success: () => { console.log('=============>success') }, fail: () => { console.log('=============>fail') }, complete: () => { console.log('=============>complete') } }) intervalId = setInterval(function () { totalTime++; console.log('=============>totalTime:' + totalTime) }, 1000); }, 测试基于官方提供demo进行测试，小程序版本：2.22.0 模拟器版本：iphone 6/7/8 (275*667 Dpr:2)
