Description
Hi.
I'm running VirtualBox 5.0.0 under Win7 on a Lenovo T550 laptop. My guest O/S is CentOS 7.1. On the Win7 system, the integrated laptop webcam works perfectly. If I export the webcam to the Linux guest O/S (ie. in the "Devices" menu, under Webcams, "Integrated Camera" is selected.), then the guest O/S sees the webcam as well (uvcvideo, 04ca:703c). In the guest O/S, if I start "cheese" (a tool to take pictures and video from the webcam), I should see a live preview of the webcam input. The light on the camera does go on and stays on, but rather than displaying the live preview, I get the first frame that cheese saw when it was started. That frame doesn't change. I can click "take picture" over and over but it will capture the identical frame. If I change the video resolution in cheese, then the frame changes one more time.
I tried on an older VirtualBox version 4.3.18, and the problem is identical. I tried with CentOS 6, under both VirtualBox versions 4.3 and 5.0 (with proper guest extensions), and had the same problem. I tried with a Lenovo T540p laptop (previous generation of this laptop), and the live preview in cheese worked on both 4.3 and 5.0.
It's important to note that the problem is not explicit to just "cheese". For example, if I visit the following URL in Firefox:
http://mdn-samples.mozilla.org/s/webrtc-capturestill/
This is a WebRTC demo. In the left box, I should see a live preview of my webcam. I get the same problem (1 frame). The same demo works properly on the underlying Linux box, and from the T540p laptop.
I installed a CentOS 7.1 system from scratch with no vbox, and the camera works fine with cheese (and demo above). I installed VirtualBox 5 on this CentOS 7.1 system, and then installed the same VM that was having the cheese problem, and the video passes through perfectly as well! I would guess this means that the issue is in the Windows Extension pack.
I'm really really anxious to resolve this issue soon because I really need it for later this month. If there's any help that I can provide, please let me know.
Jason.
What information can I provide to aid in resolving this issue? I have upgraded to the latest vbox 5.0.8 along with the guest extensions and have the same problem. Only 1 frame of video is captured.
