如何使用摄像头preVIEW上TextureView录制视频 [英] How to record the video using camera preview on TextureView
问题描述
我已经在一些Android 4.0的设备玩TextureView。例如，我试图开发一个简单的应用程序，它可以录制视频，并使用TextureView为其preVIEW。但是，据我读到了Android API文档，标准MediaRecorder需要一定的表面，以便进行视频录制，但在另一方面，TextureView没有自己的面了，所以TextureView和MediaRecorder之间不兼容似乎存在。
I have been playing with TextureView on some Android 4.0 devices. For example, I tried to develop a simple app, which can record the video and uses TextureView for its preview. However, as far as I read the Android API documents, standard MediaRecorder requires certain surface in order to perform video recording, but on the other hand, TextureView does not have its own surface anymore, so an incompatibility between TextureView and MediaRecorder seems exist.

有谁知道如何使用标准MediaRecorder与TextureView作为其摄像头preVIEW录制视频？或者是有什么办法可以录制视频以外的其他MediaRecorder？
Does anyone know how to record video using standard MediaRecorder with TextureView as its camera preview? Or is there any way to record video other than MediaRecorder?
非常感谢你。
推荐答案
根据这个问题，在果冻豆及以上，你根本不叫设置previewDisplay（）和 MediaRecorder 将自动使用所用的相机preVIEW 。我可以证实，没有要求设置previewDisplay（）确实工作，至少在Android 4.2中，摄像机 preVIEW被设置为一个 TextureView 。我还没有尝试过在旧的Android版本，这证实4.1的作品。
According to this issue, on Jelly Bean and higher, you simply don't call setPreviewDisplay(), and MediaRecorder will automatically use the preview used by the Camera. I can confirm that not calling setPreviewDisplay() does indeed work, at least on Android 4.2, when the Camera preview is set to be a TextureView. I have not yet tried this on older Android versions to confirm that 4.1 works.
这确实留下了一点的差距，在3.0-4.0的Android设备可能无法使用 TextureView 为previews。
This does leave a bit of a gap, in that Android 3.0-4.0 devices perhaps cannot use TextureView for previews.
