Android中Camera和Camera2之间的区别 [英] Difference Between Camera and Camera2 in Android

问题描述

我正在构建一个类似于社交媒体的应用程序，人们可以在其中共享照片和视频(如Instagram).这就是相机对我的应用非常重要的原因.现在，camera2 API使我感到困惑.我想在API级别11+上运行我的应用.我知道camera2仅在API级别21+中可用，因此，我需要设计两个API，一个(相机)用于旧版本，另一个(相机2)用于较高版本.问题是我刚开始学习Android，不知道这两个API之间的主要区别是什么.

I'm building an App which is similar to social media where people can share photos and videos like Instagram. That's why Camera is very important for my app. Now camera2 API is confusing me. I want to run my app on API level 11+ . I know camera2 is only available in API level 21+ So, I need to design two APIs one(camera) for older version and second(camera2) for higher version. Problem is that I just started to learn Android and I do not know what is the main difference between these two APIs.

Camera2 API提供哪些主要功能?
还是Old Camera API有任何缺点?

What main features are available in Camera2 API ?
Or Is there any drawback of Old Camera API ?

我的应用程序中需要三件事.

I need three things in my App.

1-简单拍摄照片 2-连拍图片(创建GIF图像) 3-简单的视频录制.

1- Simple capture photos 2- Burst pictures (To create GIF Image) 3- Simple video recording.

哪个Camera API对我有好处?

Which Camera API is good for me ?

推荐答案

旧相机API在#1和#3上可以正常使用；如果您对视频分辨率GIF没问题，也可以执行#2.

The old camera API will work fine for #1 and #3; if you're OK with video-resolution GIFs, you can do #2 as well.

您将需要camera2(然后需要支持快速，全分辨率捕获的设备-请参阅完整硬件级别.)，如果您想以〜1080p以上的分辨率进行连拍.

You'll need camera2 (and then devices that support fast, full-resolution capture - see the BURST_CAPTURE capability, or any device that supports the FULL hardware level.), if you want bursts at resolutions above ~1080p.

您可能可以从 CameraView 非官方支持库开始，然后根据需要对其进行修改.它支持两种API，并且根据设备的API级别进行选择.

You can probably start with the CameraView unofficial support library, and modify it as needed. It has support for both APIs, selected based on API level of the device.
