使用新的Camera API捕获高fps视频 [英] Capture high fps videos using new Camera API

问题描述

我尝试以高帧频捕获来自相机的视频。 （60fps / 120fps）
我在Nexus 5设备上测试。从CameraCharacteristics，可用的fps范围是[15,15]，[24,24]，[7,30]和[30，30]。到目前为止，我可以节省最多30fps的视频。有没有办法使用新的相机API捕获高fps视频？还是这是一个设备硬件限制？

I'm trying to capture videos from camera at high frame rates. (60fps/120fps) I'm testing on Nexus 5 device. From CameraCharacteristics, the available fps ranges are [15,15],[24, 24],[7, 30] and [30, 30]. So far I could save maximum 30fps videos. Is there a way to capture high fps videos using new camera APIs? Or is this a device hardware limitation?

推荐答案

我认为，Nexus 5无法录制60 fps视频主要是驱动程序的限制。
请参阅： https://github.com/PkmX/lcamera - 60/120 FPS记录部分。它需要一个自定义驱动程序来启用此功能，这基本上打破了所有其他相机应用程序，所以我怀疑它不是一个真正的干净的解决方案。 Nexus 5支持官方只支持30 fps。

I think, Nexus 5 not being able to record 60 fps videos is mostly a driver limitation. See this: https://github.com/PkmX/lcamera - "60/120 FPS Recording" section. It needs a custom driver to enable this functionality which basically breaks all other camera apps, so I suspect it's not really a clean solution. Officially only 30 fps is supported on Nexus 5.

此外，我刚刚发布了一个类似但更为一般的问题：在Android上访问高fps摄像头
