[jitsi-users] Windows XP SP3 - Jitsi 2.2 and UVC USB camera


#1

Are there any requirements for cameras attached to Jitsi that have to be met?
Do these differ, depending on host operating system?

Jitsi's webcam support is operating system-specific i.e. Jitsi employs
APIs native to the respective supported operating system to capture
video (frames): DirectShow is on Windows, QuickTime Kit on OS X and
Video for Linux Two on Linux. Consequently, the first requirement is
that the webcam of choice is supported by the respective API.

Generally, Jitsi utilizes uncompressed formats such as various kinds
of RGB and YUV and explicitly supports the MJPG compressed format on
Windows and Linux. That's pretty much the second and last requirement.

#3

How do I diagnose why a camera I have is not being seen by Jitsi.

The camera is claimed to be a UVC device, and indeed no drivers were needed for Windows XP to show an image in Windows Explorer. However the devices list on Jitsi is empty when I go into the settings for video.

What is the relationship between DirectShow and UVC?

I found this article on MSDN...
http://msdn.microsoft.com/en-us/library/windows/hardware/ff568651(v=vs.85).aspx

This suggests that the DirectShow API in Windows doesn't support streaming or frame based formats, H264 and a few other bits and pieces under Windows XP. We are going to try Window 7, which adds support for stream based and frame based formats, to see if that fixes it, maybe even Windows 8.

Does that sound like the cause of the issue I am having?

Of course streaming can be done with Microsoft XP. It is done all of the time.
Even lowly types like skype use it. If fact "streaming" is nothing more than inputing or outputting a string of data units, and nothing more.

Are you suggesting that all XP users dump their currently adequate system and purchase another Microsoft proprietary system, so the can use it's library (which a programmer wrote).

Jitsi should either remove all of it's declarations of XP support, since in fact Jitsi isn ot supported on XP and developers are not interested in making it work, which is understandable. But, it should not be advertised as supported and lead people to trying it out wasting their time and jitsi's server's time, not to mention incoming support requests.

Not at all. I am trying to work out why a rather expensive, allegedly UVC compatible camera I have got, is not seen by Jitsi. It works fine at Windows XP system level. There is a live preview of the camera output in the 'My Computer' Windows Explorer window, however when in Jitsi, going to the options menu to select the video device, it is never there. When the original Logitech webcam is connected, it is seen straight away.

Well I've tried Windows 7 and it is no better than with XP, so it would appear not to be that answer anyway.

Hey there,

Could you please point us to the places on jitsi.org where we make
such support declarations?

XP is currently in a best effort situation. It is what it is. I know
at least some users are happily using Jitsi on it. I also know that we
are somewhat unlikely to address XP-specific problems that require
more than an hour.

Of course, that was mostly "we" as in BlueJimp. I can't speak for
other contributors, although to the best of my knowledge there aren't
many XP die hards among the regulars either.

Of course patches are welcome from anyone.

Emil

Even lowly types like skype use it. If fact "streaming" is nothing more than inputing or outputting a string of data units, and nothing more.

Are you suggesting that all XP users dump their currently adequate system and purchase another Microsoft proprietary system, so the can use it's library (which a programmer wrote).

Jitsi should either remove all of it's declarations of XP support, since in fact Jitsi isn ot supported on XP and developers are not interested in making it work, which is understandable. But, it should not be advertised as supported and lead people to trying it out wasting their time and jitsi's server's time, not to mention incoming support requests.

I found this article on MSDN...

This suggests that the DirectShow API in Windows doesn't support streaming or frame based formats, H264 and a few other bits and pieces under Windows XP. We are going to try Window 7, which adds support for stream based and frame based formats, to see if that fixes it, maybe even Windows 8.

Does that sound like the cause of the issue I am having?

Have you tried with one of the Jitsi nightly builds? I don't know the
exact changes, but there was at least one commit[1] since 2.2 was
released which adds support for more devices. I have a TeckNet camera
which is recognized by the nightlies, but not by 2.2.

Regards,
Boris

Many thanks for that pointer I shall take a look tomorrow.

I have just tried Windows 8 as well, that is no better either. This camera is turning out to be the worst investment we've made! It has several other 'issues' as well, but we are stuck with it, so to get some basic use out of it would be good.

Pleased to report that nightly build 2.3 works with the UVC camera fine, with XP, 7 and 8. Thanks for your help everyone.
