by Lindsay Sprinter 27 Oct '11

Anybody know of a currently availible analogue video capture device currently avaible that works with linux. Video Audio in being preffered. There appear to be a signifcant number of USB devices around any of these work with linux. Mind you since it is only for conversion of some tapes to digital probably does not matter if it only works in Windows XP as long as the software does not cost the earth. Lindsay

[luv-main] deleting files on NFS
by Russell Coker 27 Oct '11

27 Oct '11

I have a Debian/Squeeze NFS server running kernel 2.6.32-5-xen-amd64 and a Debian/Unstable NFS client. I just did "rm -rf" on a directory containing 4.2G of files that was mounted via NFS. It was a directory with three large files which were MP4 files captured from digital TV, I had watched them all recently with mplayer. df didn't report any more free space. To get the space back I ended up commenting out the line from /etc/exports, running "exportfs -r", then umounting and mounting it. I didn't check whether the space was free after running "exportfs -r", it probably was. It seems that I was caught by the issue of open file handles. NFS is stateless so it doesn't necessarily process deletion for some time to handle the case of a NFS client that is running processes with open file handles. How long is this supposed to go for? Can I force NFS to give up such caching when I need the space sooner than NFS will free it? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

In my case, I have additional constraints for any serious speaker system - RF immunity. Most PC speaker systems make excellent broadband radio receivers.

The card appear to be enabled OK. I have reported it as a bug to launchpad and their tests also indicated that there is a problem. Bob

[luv-main] Cdrom upgrade
by Bob 26 Oct '11

26 Oct '11

Hello all, I have a laptop running Kubuntu 11.04. In attempting to upgrade to 11.10 via the internet the upgrade fails citing unable to get Kubuntu -wallpaper, so I downloaded the alternate cd, disconnected from the internet and attempted to upgrade from the cd using 'sh cdromupgrade'. Normally I would use my own logon but in a last desperate attempt I changed to root. Results are shown below: root@Toshiba:/media/cdrom0# sh cdromupgrade No protocol specified /usr/lib/pymodules/python2.7/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display warnings.warn(str(e), _gtk.Warning) can't load DistUpgradeViewGtk (No module named vte) can't load DistUpgradeViewGtk3 (Namespace Gtk not available for version 3.0) No protocol specified update-manager: cannot connect to X server :0 Is there something wrong with the command I have used? Thanks Bob

And back to luv-main. Could we do something about finding the setting in the new mailing list software to remove the nasty "[luv-main] [luv-talk] [luv-main]" subject line cruft that will no doubt appear once this ends up back on the luv-main list? I fear that it's been a month now, and might almost become accepted behaviour to keep munging the subject line like that. And then it's only a short path down the track to LUV-main become a web-forum <shudder>. -- Tim Connors

[luv-main] Booting Ubuntu on EFI PC
by dan062 25 Oct '11

25 Oct '11

HI guys, Having problems booting with Ubuntu 11.10 The PC works perfectly on live CD, detecting and configuring video correctly. Ubuntu install with no errors using default options. However when booting off newly installed OS, it just shows a blank white screen after showing a few bios stuff - I am not even sure if it has booted and it is just a video issue or a complete crash - but it does not seem to respond to keyboard. This is a new ASUS built box with a P8P67 LE Mobo. This has a EFI bios. So Is there a different installation procedure that needs to be done for EFI ? (its my first experience with EFI) Most EFI stuff from google seem to relate to Mac booting! Cheers Daniel

[luv-main] Imagemagick - convert to same format as another image
by cory seligman 24 Oct '11

Hi all, I have an little microcontroller and LCD that can display windows bmp files, but it only seems to work with the ones provided. When I create a bmp file with the same basic resolution, colour depth etc, it fails to display. Does anyone know of a way to convert an image to bmp format having the same characteristics as a reference image? I'm sure I could work it out for this specific case, but it would be handy thing to be able to do in general. anyone? cory

[luv-main] joining video files
by Lindsay Sprinter 21 Oct '11

21 Oct '11

I have downloaded a 4 part video that had been split into parts for down loading and I wish to put back into a single file. Any one have any sugestions for a decent utilty for this. I minor point is it plays the files at the wrong aspect ratio the correct being 4x3. The files are a fairly rare german film of the history of the Schnellboots (literaly fast boats, the german ww2 torpedo boats).. The following is part of the status from mplayer.......... ========================================================================== Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264) ========================================================================== ========================================================================== Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding) FAAD: compressed input bitrate missing, assuming 128kbit/s! AUDIO: 44100 Hz, 2 ch, s16le, 128.0 kbit/9.07% (ratio: 16000->176400) Selected audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio)) ========================================================================== Lindsay
