VLC running in Ubuntu/ VMware Player problem

[jvdstoel]

Hello,
We use VMware player for a lot of development purposes. VMware player is running in Windows XP.
I have connected a uvc logitech camera to my laptop. (tested with two different models)
What I encountered is the following: (all OS'es running in VMware)
Ubuntu 10.04 & VLC & xawtv installed from the repository (latest version):
- Both VLC & xawtv show the camera image.
Ubuntu 10.10 & VLC & xawtv installed from the repository (latest version):
- Only xawtv shows the camera image.

VLC shows:

main debug: thread ended
main debug: changing item without a request (current 2/3)
main debug: nothing to play

What is the reason of this problem and how can it be solved?

Thanks,
Johan

kernel says the device is busy. Another application is using it.

Dear Remy,

This would be too easy - I can assure you this is not the case.
I already discusssed this issue with Jean-Paul Saman (I guess you know him); he is working for us and he advised me to post this topic.

We are rather convinced here is a bug somewhere.

Best regards,
Johan

It is unlikely that VLC invents EBUSY... But if you think it does, you're welcome to propose a fix.

If I would have the knowledge to debug this further, I would do it. But I don't have it...
