修改方案

868          const hardware::camera2::params::OutputConfiguration &outputConfiguration,
869          /*out*/
870          int32_t* newStreamId) {
871      ATRACE_CALL();
872  ... ...
917      OutputStreamInfo streamInfo;//用这个对象可以修改配流size
918      bool isStreamInfoValid = false;
919      const std::vector<int32_t> &sensorPixelModesUsed =
920              outputConfiguration.getSensorPixelModesUsed();
921      for (auto& bufferProducer : bufferProducers) {
922          // Don't create multiple streams for the same target surface
923          sp<IBinder> binder = IInterface::asBinder(bufferProducer);
924          ssize_t index = mStreamMap.indexOfKey(binder);
925          if (index != NAME_NOT_FOUND) {

927                      "(ID %zd)", mCameraIdStr.string(), index);

929              return STATUS_ERROR(CameraService::ERROR_ALREADY_EXISTS, msg.string());
930          }... ...
983      } else {//if(String8(mClientPackageName) == "com.xxx.xxx")//{//   直接修改streamInfo.width 、streamInfo.height即可//}
984          err = mDevice->createStream(surfaces, deferredConsumer, streamInfo.width,
985                  streamInfo.height, streamInfo.format, streamInfo.dataSpace,
