xine options can be changed with .... xine!!

I'm not an avid KDE4 fan... so who knows....

The equivalent in mplayer is x11.

With regards to webcam. I use luvcview to test (only works for some
web cams).

For skype you might find that disabling udev device creation for your
webcam might fix the problem.

Hi there,

yes yes, you change the xine options with xine but not the video outputs in KDE4 (or at least I couldn't) but it's no problem for me to use kaffeine KDE3 at all so, that part is solved.

I tried luvcview and I get my usual now black screen... and the output from luvcview is:


luvcview 0.2.4

SDL information:
Video driver: x11
A window manager is available
Device information:
Device path: /dev/video0
Stream settings:
Frame format: YUYV (MJPG is not supported by device)
Frame size: 640x480
Frame rate: 30 fps


I also checked the udev device creation problem... but it seems that nothing is created.

I also note you have 1.0.16 xine rpms. What makes you think you have 1.0.15 ? Why are you referring to 1.0.15 of xine ?? I see no evidence you have 1.0.15 libraries.

As to whether that has anything to do with your problem, I don't know.

Clearly your web cam works with this nvidia driver, as we proved that above. What web cam do you have? What is the output of:

lsusb

Note you need usbutils installed for that command to work.

The 1.0.16 and 1.0.15 are now stable 'cause I went to Software.opensuse.org and searched for XINE... and installed the 1.0.16 from there. But seems that that "conflict" was not the point because everything keeps being the same.

I don't really know where I got those gstreamers... I'll double check the packman repository

The output lsusb is:

Bus 008 Device 003: ID 04f2:b033 Chicony Electronics Co., Ltd

Thank you for your time and quick response!!

The openSUSE versions on my PC are:
phonon-backend-gstreamer-0_10-4.2.0-40.18
phonon-backend-xine-4.1.3-4.2.9

Is this something to do with a KDE-4.x update? A gnome update?

I think yesterday (or this morning) has been an update for KDE 4.2... so in the trial and error... I got the new ones (actually, for phonom-backend-xine, I have a new update available, the 4.3.1-4.1)

OK, that was just a "sanity check" to confirm you were using the correct driver. I note from here: Linux UVC driver & tools
that your webcam is listed:

04f2:b033  	USB 2.0 1.3M UVC WebCam (Asus M70VM notebooks)  	Chicony Electronics

and the uvc is the driver you need to be using.

I still don't understand your 1.0.15 comment, as 1.0.16 is the packman packaged xine version. But I assume thats a mute point.

Anyway, I've lost track of your problem. Your webcam works. And you can play video with a judicious video output module setting. As noted, I can't help with your skype efforts.

Good luck in that (skype).

Yup, you are right, they are from GNOME's repository and seems that the priority of that repo is 20 while packman's is 99. I guess that's why.

Should I change the GNOME's repo priority to 99 and choose for packman's packages..?


wooow... seems that I'm learning lots of things today

Thanks for the help and time Oldcpu, I really appreciate that!

Yes, everything is almost solved... but the webcam is not working properly. As I posted above, I don't know why I get a black screen when trying also luvcview. That is strange. I know I have no conflict with anything and I can even record an AVI with it. But if I turn it on I see a black screen.


MOREOVER! Last minute test. I tried skype, Kopete and amsn. Now people can see me on my webcam, but I cannot see my preview neither the image coming from the other person's webcam.






Thanks anyway!
