QUESTION
If I run any of the following commands from the examples in the documentation, using ffmpeg
4.2.2 on Windows 10, the requested information is successfully displayed in the console, but the process exits with exit code 1
, instead of the expected 0
(success).
ANSWER
Answered 2021-Nov-23 at 12:19Exit code 1
while listing devices with dshow
is the expected output since the code goes for an immediate exit in this case by using AVERROR_EXIT
and no media output is produced.

QUESTION
In CameraX Analysis, setTargetResolution(new Size(2560, 800), but in Analyzer imageProxy.getImage.getWidth=1280 and getHeight=400, and YUVToByte(imageProxy.getImage).length()=768000。In Camera, parameter.setPreviewSize(2560, 800) then byte[].length in onPreviewFrame is 3072000(equales 768000*(2560/1280)*(800/400))。How can I make CameraX Analyzer imageProxy.getImage.getWidth and getHeight = 2560 and 800, and YUVToByte(ImageProxy.getImage).length()=3072000? In CameraX onPreviewFrame(), res always = null, in Camera onPreviewFrame(), res can get currect value, what's the different between CameraX and Camera? And what should I do in CameraX?

...ANSWER
Answered 2021-Jun-13 at 01:15With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution()
states that:
The maximum available resolution that could be selected for an ImageAnalysis is limited to be under 1080p.
So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis
resolution that has the same aspect ratio you requested (2560/800 = 1280/400).

Explaining about my problem: I was looking for a way to rotate the camera at angle depending when the player triggered an object
and what I was hoping is that to rotate the camera at any degree like 90, 40 , 30 or something like that.
What I tried/wrote * Update:*
Which work but only in the camera_follow script, it just rotate base on the player facing.
...ANSWER

If you want to set the rotation on the Y axis it would be:
QUESTION
I recently started to learn how to use Android camera2, but when I want to take a picture it will crash. I just know where it crashed but I don't know why it . Does anyone help me to find the problem? thanks.
...ANSWER
Answered 2020-Jul-21 at 22:47You can't add a Surface in a CaptureRequest that wasn't part of the Surfaces given to createCaptureSession. In your code, you're creating an ImageReader only once you want to take a picture, and the API is telling you that's not valid:
Caused by: java.lang.IllegalArgumentException: CaptureRequest contains unconfigured Input/Output Surface!
So either set up the ImageReader the same time you're setting up your capture session and include its Surface in the output target list, or create a new capture session in takePicture that includes the newly-created ImageReader.
The latter isn't really recommended, because creating a new capture session will pause preview briefly. So create the ImageReader where you're calling CameraDevice.createCaptureSession, and make sure you keep the ImageReader as part of your enclosing class to avoid it getting garbage-collected.
QUESTION
I'm working on a golf game in unity, where I have a camera orbitting a ball based on mouse x and y input. The camera controller code works fine until I start applying force to the ball. Please see camera controller code below:
...ANSWER
Answered 2020-May-29 at 19:50One solution could be to have inside the ball gameObject 2 childs, one with the ball that will rotate, and another one with the camera. This way the camera will follow the parent gameObject, who doesn't rotate (but you should update the position).
The other one, and the one I like it the most is to do not child the camera on to the ball gameObject, just update the camera position from the ball position, JUST the position, not the rotation. Something like:
