如何使用gstreamer访问8MP前置CSI摄像头？

嗨Dion，感谢您对英特尔®Aero计算板的兴趣。请您提供有关您的设置的更多详细信息？您打算在哪里打开流：直接在无人机或远程计算机上？如果是
远程计算机，请确保它已正确连接到无人机的接入点。另外，请确保您正在更改QGC中的视频设置：https：//github.com/intel-aero/meta-intel-aero/wiki
/ 06-Cameras-and-VideoDid你试试/ dev / video0？当你运行那个命令时什么不能正常工作？你能提供你收到的输出吗？任何可以帮助我们识别问题的其他信息会
非常感激。理查德，乔治

Hi Dion,

Thank you for your interest in Intel® Aero Compute Board.

Could you please provide more details about your set-up?
Where are you trying to open the stream: directly on the drone or on a remote computer?
If it is a remote computer, please make sure it is connected to the drone's access point properly.

Also, please make sure that you are changing the video settings in QGC: https://github.com/intel-aero/meta-intel-aero/wiki/06-Cameras-and-Video
Did you try /dev/video0?

What isn't really working when you are running that command? 
Could you please provide the output that you receive?

Any additional information that could help us to identify the problem would be much appreciated.


Regards,
George

HI George，
我只是试图直接在aero上启动UDP或RTSP流，所以我可以在其他地方接收它。

我想运行类似的命令
sudo gst-launch-1.0 v4l2src device = / dev / video0 do-timestamp = true！
video / x-raw，format = YUY2，width = 640，height = 480，framerate = 15/1！
autovideoconvert！
vaapih264enc！
rtph264pay！
udpsink host = 192.168.1.147 port = 5600
但我得到这个错误，它立即退出：
aero @ ubuntu-aero：〜$ sudo gst-launch-1.0 v4l2src device = / dev / video0 do-timestamp = true！
video / x-raw，format = YUY2，width = 640，height = 480，framerate = 15/1！
autovideoconvert！
vaapih264enc！
rtph264pay！
udpsink host = 192.168.1.147 port = 5600

HI George,
 
I'm just attempting to start the UDP or RTSP stream on the aero directly so I can receive it elsewhere.
I'd like to run a command similar to

sudo gst-launch-1.0 v4l2src device=/dev/video0 do-timestamp=true ! video/x-raw, format=YUY2, width=640, height=480, framerate=15/1 ! autovideoconvert ! vaapih264enc ! rtph264pay ! udpsink host=192.168.1.147 port=5600

but i get this error with it exiting immediately:

aero@ubuntu-aero:~$ sudo gst-launch-1.0 v4l2src device=/dev/video0 do-timestamp=true ! video/x-raw, format=YUY2, width=640, height=480, framerate=15/1 ! autovideoconvert ! vaapih264enc ! rtph264pay ! udpsink host=192.168.1.147 port=5600

aero@ubuntu-aero:~$

I also stopped csd so it wasn't interfering (systemctl stop csd).
Running the command with video13 works fine! just not video0.
 
I'm familiar with QGC, the the issue doesn't lay there.
 
Just can't open the front facing camera...
 
Cheers
Dion

您好Dion，这是工程团队正在研究的800万像素摄像头的一个已知问题。您可以找到一个可用于从800万像素摄像头捕获帧的示例应用程序但不幸的是，它太暗了.https：//
github.com/intel-aero/sample-apps/tree/master/hd-cameraBest问候，乔治

Hello Dion,

This is a known issue with the 8MP camera that the engineering team is looking into. 

You can find a sample app that can be used to capture a frame from the 8MP camera but unfortunately, it is too dark.

Best regards,
George
