Hi, GQii I know what kind of problem you are talking about. but 640x480 is not high resolution. because i use 1920x1080 resolution. maybe don't use 4K. you should check external camera spec and modify default (resolution, frame rate). The default resolution are modified jni and java files. Thank you.

@Jade-source First of all, thank you for your reply. I tried to modify resolution and frame rate in the past, but the effect is still as shown above. I'm not a solution to this problem right now.

@GQii you should use UVCCameraHandler.createHandler(Activity, CameraViewInterface, encoderType, 1920, 1080, format) when preview is FHD.

I think the external camera does not compress video format well.
