最近做短视频项目，用的是阿里云的sdk,接了阿里的sdk后，在推出拍摄界面操作中，总会不定期的崩溃，
报错如下

可以看到，报错信息出现在“/lib/arm64/libFace3D.so”这个库中
这个时候就有点难办了，因为这个库已经封装成so,找错都不好找，
难办也要想办法，我们来一步步分析
先来看下 libFace3D.so 这个so是哪个项目的，
使用everything 搜索后发现这个库属于AliyunRace-1.0.0
'com.aliyun.race:AliyunRace:1.0.0'
这个库还是1.0.0版本的，有问题也很正常，那么，能不能升级试下呢，
网上搜了一圈，然后又在阿里的api文档中找了一圈，没发现有更新的库
没办法，只能弃用这个库了，弃用这个库之后，发现“RaceManage”这个类报错了，
好吧，原来是RaceManage这个类在用这个库，
那么现在的问题就变成了怎么绕开RaceManage这个类
这个就简单了，
AlivcRecordInputParam recordParam = new AlivcRecordInputParam.Builder()
.setResolutionMode(3)
.setRatioMode(2)
.setMaxDuration(15000)
.setMinDuration(3000)
.setVideoQuality(VideoQuality.HD)
.setGop(30)
.setVideoCodec(VideoCodecs.H264_HARDWARE)
.setIsUseFlip(false)
.setVideoRenderingMode(RenderingMode.Race)
.build();
上面的是之前的参数
改成下面的
AlivcRecordInputParam recordParam = new AlivcRecordInputParam.Builder()
.setResolutionMode(3)
.setRatioMode(2)
.setMaxDuration(15000)
.setMinDuration(3000)
.setVideoQuality(VideoQuality.HD)
.setGop(30)
.setVideoCodec(VideoCodecs.H264_HARDWARE)
.setIsUseFlip(false)
.setVideoRenderingMode(RenderingMode.FaceUnity)
.build();
即把
RenderingMode.Race 这个参数改为 RenderingMode.FaceUnity
终于不再崩溃了，问题解决。。。
另外要注意
.setVideoCodec(VideoCodecs.H264_HARDWARE)
要用H264_HARDWARE 这个参数，不然视频录制的时候摄像头晃动的话视频会卡。
