Solved CUPS remote printing problem on Ubuntu 8.10 (Intrepid Ibex)

[NOTE]Please drop a comment, if this article solved your problem. Many people are coming to this page having printing problems on Ubuntu 8.10, but I don’t know if the solution described on this page really helps. Thanks a lot.


I’m on Ubuntu 8.10 (Intrepid Ibex) now, and wanted to set up my printer, which actually is remotely connected to my server.
The Server is an Ubuntu 7.10, but with a very old (about 4y) samba config (smb.conf) and a freshly installed CUPS server. Originally it was a set up from the C’t Server project. I’ve tweaked the smb.conf a lot since those days, to keep this whole thing going. All was fine, even with my last client. It was an Ubuntu 8.04 installation. Continue reading

Mplayer Fedora Compilation Problem

All of a sudden I couldn’t compile mplayer on my fedora8 box:

Linux moon 2.6.26.6-49.fc8 #1 SMP Fri Oct 17 15:59:36 EDT 2008 i686 athlon i386 GNU/Linux

I’ve tried to compile revision #27827, but it gave me after the make command always this (see below), no matter what I’ve tried.

.
collect2: ld returned 1 exit status
.

and a really big bunch of undefined references.

I’ve installed ffmpeg and x264, and compiled mplayer like this:

./configure --disable-libavutil_a --disable-libavcodec_a --disable-libavformat_a

Then it worked. Since I’m not an expert, I don’t know what exactly I have done. However it’s working now.

New Icons for MMS

I’ve created a new MMS icon for the final release.
Let’s see if Anders is going to like it. I do :-)

The black color in the background comes from the conversion of the png image. It should be white actually. Click on the image for the bigger [148kb] png image to see the correct colors.

BlackLight Power And My Two Cents To It

First of all, this is computer and Open Source related Blog, and I wasn’t and still am not sure, if this is a really good idea to mention this stuff about BlackLight Power here, since I’m trying really hard to keep this Blog above a certain level.
But a few days ago I’ve read an article at Telepolis about a “Breakthrough in Extracting Energy from Hydrogen? “. Well – knowing that Telepolis sometimes tends to report about weired stuff, I was very much astonished about what I’ve read there.
I’ve started to Google around, and read various stuff on the Internet, including the Wikipedia entries on that. I’ve ignored the BlackLight Power site itself, since I didn’t intent being brainwashed. But I’ve found also on YouTube this presentation: Continue reading

Playback Problem with Canon HF100 AVCHD (.mts) and CoreAVC 1.8.5.0 (Linux)

I try to play back footage from Canon’s HF100 camcorder, which records with up to 17MBit/s. Here for I’m using CoreCodec’s latest CoreAVC decoder on Linux with coreavc-for-linux. Version 1.8.5.0 has been released on 17th of October 2008, and I was awaiting this version eagerly, since I had the expectation, AVCHD (.mts) is going to work with the new version. I’ve also started this little page to collect affected AVCHD camcorders in a list, where you see what is known not to work atm for CoreAVC Decoder. Help appreciated.
The day they’ve published their new decoder, they wrote into their changelog: Continue reading

CoreAVC 1.8.5 on Ubuntu 8.10 x86_64 (Intrepid Ibex) HOWTO

This is small HOWTO about running the CoreAVC decoder (dshowserver) on a 64Bit Unbuntu 8.10 (Intrepid Ibex)
This should work for other 64bit Linux-Distros, like Debian, Fedora, SuSE, Gentoo, etc… also. With the CoreAVC decoder for Linux you should be able to play back H.264 content in FullHD (1920x1080p, VC1 is not supported). In comparison to the the native mplayer H.264 playback, only CoreAVC is able to utilize all cores of your CPU simultaneously at the moment. Please consider, NVIDIA has published a Beta driver (180.06, 180.08, 180.11), which allows already now a rudimentary hardware acceleration support for HD content (including VC1). Feedback welcome.

The Linux AVCHD (.mts) Playback HOWTO with MPlayer

Alan fixed the Segmentation Fault issue for CoreAVC version 1.8.5.0, so Matroska files can be played back again. See this thread at his project site: #62

Unfortunately AVCHD has still issues. So CoreAVC version 1.8.5.0 still doesn’t work regarding playback of AVCHD footage from my Canon HF100. I think Panasonic HDC-SD1/5/9/100 is also affected.
If you have a at least 2.7GHz processor, you can use the latest mplayer from their repository. Continue reading

List of affected AVCHD CamCorders

This is a list of AVCHD Camcorders, which do not work with CoreAVC decoder version > 1.7.0.

Like in older versions, such as 1.7.0 and 1.8.0, CoreAVC version 1.8.5 has still problems playing back AVCHD. The affected camcorder models I know of are:

  • Canon HF10
  • Canon HF100
  • Panasonic HDC-SD1
  • Panasonic HDC-SD5
  • Panasonic HDC-SD9
  • Panasonic HDC-SD100


The playback still jitter a lot if used without a deinterlacer, and I’ve got only about 10 frames a second (estimated). Seeking within the footage works now (was broken in version 1.8.0), wheres regarding the existing problems it’s a really cold comfort.
A workaround, for playing back AVCHD footage is described here at several places. Just use latest mplayer and a decent CPU.
If anybody likes to extend the list of affected camcorder models, please post them here, I’ll update the list above and will keep tracking this issue.
I’m using CoreAVC-for-Linux. If you are using Windows, please post this information as well as the version of CoreAVC you are using. Thanks.

[UPDATE] I’ve posted a question at CoreCodec’s forum, where I ask, whether AVCHD content supposed to work at all. I’m not very confident in the meantime, but let’s try it anyway.

CoreCodec Forum not available anymore

For unknown reasons, the corecodec forum isn’t available anymore.
The site, which is coming up, has nothing to do with the forum itself: http://forum.corecodec.com

Unfortunately this is the only source for tracking my issues with the latest CoreAVC 1.8.5 decoder on Linux.

As soon as this site will be available again, I will update this section. The forum itself is down since 20th of October 2008. If there was an accouncement regarding this shutdown, then I didn’t see it.

[UPDATE] The forum is available again. It came back to live at 21th of October, 2008 at about 10AM MEST. The reason for the break down is still unknown. There is no explanation at their site yet.

[solved] Problems with CoreAVC 1.8.5 on Linux

[UPDATE] Alan fixed the Segmentation Fault issue for CoreAVC version 1.8.5.0, so Matroska files can be played back again. See this thread at his project site: #62. Thanks a lot Alan!
Playback of AVCHD still doesn’t work. Read this workaround for playing back AVCHD footage without CoreAVC.

On 17th of October CoreCodec released their decoder CoreAVC version 1.8.5.0.
It’s not working for Linux at the moment. This is what happens if one one uses the dshowserver to test the functionality (like described here) of the new CoreAVCDecoder.ax library in /usr/lib/win32: Continue reading
