没有preVIEW捕获视频 [英] Capture video without preview

问题描述

我想捕捉的视频没有显示出preVIEW。这里的机器人文档说，这是可能的，但没有解释如何：

I want to capture video without showing a preview. The android docs here say this is possible, but don't explain how:

http://developer.android.com/guide/主题/媒体/ camera.html＃捕捉视频

注：可以使用MediaRecorder无需先创建一个摄像头preVIEW并跳过前几个步骤，这个过程。然而，由于用户通常preFER看到了preVIEW开始录制之前，这个过程是不是这里讨论。

Note: It is possible to use MediaRecorder without creating a camera preview first and skip the first few steps of this process. However, since users typically prefer to see a preview before starting a recording, that process is not discussed here.

什么是前几个步骤跳过？

what are the "first few steps" to skip?

感谢您

推荐答案

您misinter $ P $磅的文档。它真的说什么（ 强调的我的）：

You misinterpret the documentation. What it really says (emphasis mine):

有可能使用MediaRecorder没有的的首先创建一个摄像头preVIEW 的并跳过前几个步骤，这个过程。然而，由于用户通常preFER开始录制前，看到一个preVIEW的的 的，这个过程是不是这里讨论。

It is possible to use MediaRecorder without creating a camera preview first and skip the first few steps of this process. However, since users typically prefer to see a preview before starting a recording, that process is not discussed here.

在换句话说，你可以创建一个preVIEW并立即开始录制。没有一丝的 MediaRecorder 将让你运行一个隐藏的录音片段。

In other words, you can create a preview and immediately start recording. There is no hint that MediaRecorder will let you run a hidden recording session.

此外，我同意文件，不启动preVIEW开始记录之前的附加值，可以忽略不计。

Moreover, I agree with the document that the added value of not starting preview before starting recording, is negligible.
