iOS 加速计游戏录制片段
我们正在发布一款 iOS 游戏，但遇到了录制宣传材料的问题。
目前，我们正在使用设备上的应用程序将加速度计数据传输到模拟器。然而，设备渲染 OpenGL 的速度比模拟器快得多，尤其是第四代设备。再加上截屏应用程序产生的性能影响和网络延迟，视频非常不稳定并且不能代表设备上的体验。
您将如何记录使用 OpenGL ES 的加速计游戏的玩法？
We're releasing an iOS game and we're running into the problem of recording promo materials.
Currently, we're using an application on the device to transmit accelerometer data to the simulator. However, devices render OpenGL much, MUCH faster than the Simulator, especially fourth-generation devices. Combined with the performance hit generated by the screencast application and the network lag, video is very jerky and non-representative of the experience on the device.
How would you go about recording the gameplay of an accelerometer game that uses OpenGL ES?

使用摄像机。
不，我不是在开玩笑。当您看不到设备本身如何倾斜时，加速度计游戏通常看起来非常混乱。
Use a video camera.
And no, I'm not being facetious. Accelerometer games often look very confusing when you can't see how the device itself is tilting.
我们现在也在研究这个问题。我还设置了加速度计模拟器以将加速度计事件发送到模拟器，但事件的频率太慢（根据我的经验，大约 5hz）并且使控件看起来不稳定。我认为最好的选择（如果您有 iPad 2）就是硬着头皮获取 HDMI 适配器，以及 HDMI 捕获设备，例如此设备。
We're looking into this now too. I also set up accelerometer simulator to send accelerometer events to the simulator, but the frequency of the events is far too slow (something like 5hz in my experience) and makes the controls look choppy. I think the best option (if you have an iPad 2) is to bite the bullet and get the HDMI adapter, and an HDMI capture device such as this one.
