无法打开 不支持预览尺寸

[wsdydeni]

 aspect ratio = null, getAllPreviewSizes = [], 
open camera failed, preview size(PreviewSize(width=640, height=480)) unsupported-> []

    private fun getCameraRequest(): CameraRequest {
        return CameraRequest.Builder()
            .setPreviewWidth(340)
            .setPreviewHeight(280)
            .create()
    }

设置的预览无效啊

[wsdydeni]

getAllPreviewSizes 这个获取是的空啊

建議先用 getSuitableSize 取得 size, 再用 openCamera 開啟, getAllPreviewSizes 要成功開啟才會有資料

遇到了一摸一样的错误，你们是怎么解决的？

[CameraUVC] open camera failed.
java.lang.UnsupportedOperationException: open failed:result=-99
[CameraUVC] open camera failed, preview size(PreviewSize(width=640, height=480)) unsupported-> null
SurfaceTexture-0-26548-0 disconnect: not connected (req=1)

再3.3.3 版本中我是这样解决预览问题的
override fun generateCamera(ctx: Context, device: UsbDevice): MultiCameraClient.ICamera {
val c =CameraUVC(ctx, device)
c.isPreviewSizeSupported(PreviewSize(ctx.dp2px(500),ctx.dp2px(500)))
return c
}

private fun getCameraRequest(): CameraRequest {
return CameraRequest.Builder()
.setPreviewHeight(activity?.baseContext?.dp2px(500)!!)
.setPreviewWidth(activity?.baseContext?.dp2px(500)!!)
.create()
