我可以使用 CameraX (Android Jetpack) 录制视频吗? [英] Can I record video with CameraX (Android Jetpack)?

问题描述

Google 已作为 Jetpack 的一部分发布了新的 CameraX 库.它看起来很适合拍照，但我的用例还需要制作视频.我尝试谷歌搜索，但找不到任何东西.

Google has released the new CameraX library as part of Jetpack. It looks great for taking pictures, but my use case also require making video's. I tried googling for that, but couldn't find anything.

那么，是否可以使用 CameraX Jetpack 库来录制视频?

So, is it possible to record videos with the CameraX Jetpack library?

推荐答案

是的，我们可以使用 CameraX 录制视频.我试图在 CameraX 的 Github 演示的帮助下实现自己.请参考以下代码可能对您有所帮助.

Yes, we can record video using CameraX. I have tried to implement myself with help of Github demo for CameraX. Please refer below code may it helps you.

CameraX 中的视频配置:

val videoCaptureConfig = VideoCaptureConfig.Builder().apply {
    setLensFacing(lensFacing)
    setTargetAspectRatio(screenAspectRatio)
    setTargetRotation(viewFinder.display.rotation)

}.build()

videoCapture = VideoCapture(videoCaptureConfig)

CameraX.bindToLifecycle(this, preview, imageCapture, videoCapture)

开始视频录制:

videoCapture?.startRecording(videoFile, object : VideoCapture.OnVideoSavedListener {
        override fun onVideoSaved(file: File?) {
            Log.i(javaClass.simpleName, "Video File : $file")
        }

        override fun onError(useCaseError: VideoCapture.UseCaseError?, message: String?, cause: Throwable?) {
            Log.i(javaClass.simpleName, "Video Error: $message")
        }

    })

停止视频录制:

videoCapture?.stopRecording()

与上面我在 Github 问题评论中提到的相同:https://github.com/android/camera/issues/2#issuecomment-490773932

Same above I have mentioned in Github issue comment: https://github.com/android/camera/issues/2#issuecomment-490773932

注意:使用CameraX实现视频录制的代码可能有所不同.因为上面这段代码是我自己开发的，没有任何其他参考，而是Github Demo.

Notes: There may be different in code to implementation of video recording using CameraX. Because this above code was developed by me without any other reference rather than Github Demo.
