Hey guys,

How can I upgrade from 9.04 dev to the official release? Will the update manager do it for me if I just install all of everything? I didn't see anything in there that suggested an...

Ah. Thank you. I tried that but I still couldn't connect wirelessly. I plugged a cable in though, and it works now.

Anyway...steps to fix:

sudo apt-get remove nvidia*

I had this problem before, I just had to edit the /etc/X11/xorg.conf file, and add BusID "PCI:03:00:0" to the Driver section (I have one of those new fangled hybrid cards, and apparently it needs to...

Hi guys,

I'm working on a C++ application that uses OpenCV/ffmpeg to capture video frames from my built-in webcam (Studio XPS 13). This application is really sensitive to those auto light...

Seeing as that linux is known for being so darn stable, why am I encountering freezes on such a regular basis? Seriously, every couple hours my system will lock up and become unusable. The mouse...

Forget it. I fixed it. I am genius.

Said I couldn't reinstall xserver-xorg-core because it depended on something else, but I couldn't uninstall that because that depended on something else, and...

I was having some problems with some touch buttons on my laptop, and I was hoping 9.04 might fix them. Surely enough, it did, but broke everything else.

Anyway, xserver-xorg-core was not installed...

Heh. Just tried upgrading.

Ironically, you're quite right. *They* do work now...... but none of my other buttons work anymore. Wonderful.

Even just a way to enable wifi without the keyboard would be really great...

Hi,

My touch buttons (wifi, media buttons, eject) stopped working on my Studio XPS 13.

I don't think I've changed anything, so I don't know why this would happen. Maybe one of the updates...

I wrote a program that accesses every file on my system and collects a few stats about them. This program takes a few minutes to run the first time, and about a second to run the second time. I'm...

You're getting a problem with xine? Or building OpenCV? Remember to build opencv with cmake. Otherwise, I eventually decided...

Ah... I probably skipped that page because it wasn't in english. Thanks again FakeOutdoorsman, really appreciate it :)

Just an FYI in case anyone else runs into this problem, if you get the run-time error when trying to open a videp:



You need to sudo apt-get install libxine1 and/or xine-console. Not sure which...

Ah! My saviour returns!

I'm curious how you would know to change PIX_FMT_RGBA32 to PIX_FMT_RGB32 if you've never used OpenCV before? I was thinking I could use another definition, but I wasn't...

Hi guys,

I know I've complained a bit about OpenCV before, but I'm getting a new error when trying to compile an SVN checkout of OpenCV with FFMPEG enabled.

Here's the error:

This might be a dumb question, but what to do AFTER these instructions (http://ubuntuforums.org/showpost.php?p=6122978&postcount=37)? From my understanding, that doesn't actually install any drivers....

*sigh* I lied. Forget everything I said above. Here are the new (very simple) instructions:

1. Install the latest ffmpeg svn snapshot. You need --enable-shared and --enable-swscale. This...

This... words can no longer express my frustration.

If anyone else is having the same problems I've been having, I have a little treat for you. I think I've actually managed to figure something...

Well no wonder I was having troubles. Did ffmpeg recently change their file structure or what? Doesn't seem like a good idea when other programs depend on it.

Thank you for coming to my rescue...

I'm trying to build opencv with ffmpeg. I've tried both opencv-1.0.0 and 1.1.0, but it won't detect ffmpeg.

Ah, I think you missed my edit :)

I need libavcodec51. It may have been libavutil49 that was the problem. Regardless, pointing ffmpeg to the new libraries (as I mentioned in my last post), fixes...

I need --enable-shared so that I can compile OpenCV with ffmpeg support. I'm not too concerned about all the other filters and options right now, I just need something that works.

I recompiled...

So, I've recompiled ffmpeg about a dozen times now, but I just can't seem to get it to work with --enable-shared. I get this error message:



Any idea why? Or where can I get libavcodec52? I...
