[gentoo-user] vlc oddities
Hi, I am using vlc (beside other things) to watch dvb-t using this hardware (according lspci) 01:06.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 01:06.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) . I call vlc like vlc channels.conf When changing channels with n and p there are positions in the range of channels, where vlc gets stuck. Example Start Keyresults in with chn. channel no.: 1 n 2 (video ok,vlc running ok) 2 n 3 (video ok,vlc running ok) 3 n 3 (image freezes,vlc stucks) n 5 (video ok,vlc running ok) 5 p 4 (video ok,vlc running ok) 4 n 5 (video ok,vlc running ok) 5 n 6 (video ok,vlc running ok) 6 n(image freezes,vlc stucks) n(image freezes,vlc stucks) 8 p 7 (video ok,vlc running ok) 7 p 6 (video ok,vlc running ok) ... I didnt find any logical link between the channel number, the corresponding entry in channels.conf and whether the channel is directly selectable while stepping with n or only selectable via np forward-backward stepping. With vlc-1.0.0 I didnt have this problems, after that all versions of vlc shows this unwanted behaviour. Unfortunately vlc-1.0.0 didn't compile anymore beside other reasons to not to install it. Does anyone else have this experienced and - may be - knows a solution ? Have a nice weekend! Best regards, mcc

Re: [gentoo-user] A tiny titillating taste of grub2
Apparently, though unproven, at 01:36 on Sunday 09 January 2011, walt did opine thusly: About three years ago I spent a lot of time on the grub2 mailing list, building grub2 from their svn repo, even submitting a patch or two to get it working for the *BSD family. Then I got old and tired and I settled on gentoo. I deleted all the other OS's from my machines, including (especially) Windows -- so I no longer need to multiboot five different OS's -- and so I lost interest in the sexy new features of grub2. Lately, though, I've been using multiple USB sticks, and having them plugged in at boot-time can confuse legacy grub into booting from the wrong disk, i.e. not booting at all. Very annoying. So, I installed grub-1.98 and I've found that it *does* find partitions by UUID, and even by LABEL, amongst multiple disks. Very nifty. Not so fast, though. I don't know how to write a grub.conf file that can tell grub2 how to do that automatically so I don't need to type commands at the interactive grub2 command prompt. That's where you testosterone-pumped youngsters (Dale? Volker? Alan? Neil? Anyone?) can help fix this basically silly problem. Might be worth learning how this new-fangled boot loader works. Right now I'm having Hercules' own fight trying to get Android Donut[1] and Froyo triple-booting on an Ubuntu 10.10 netbook. Ubuntu uses grub2 these days and I think I want to keep that (makes updates easier that way - the Android stuff is a manual update anyway). Let's keep the thread open and add stuff as we find it. [1] Yes, Android now runs on x86 :-) http://www.android-x86.org [2] I'llet testosterone-pumped passed (I'm the BOFH at work) but I dunno about youngsters, this here fellow has grey in his beard. Actually he has a grey beard with a few bits of brown in it :-) grub2 is enough different from legacy grub to make the learning curve very steep -- but I'm only about half-way up the curve and I'm fading fast. (I usually unplug the offending USB stick and reboot :) If anyone here is interested enough to spend some real time and effort on grub2, I can offer a few pointers, but I'm not willing to do the real grunt work myself.

Re: [gentoo-user] A tiny titillating taste of grub2

Indeed it does, except for grub.info, which is not nearly complete. Methinks a modular build system is in order here. Why should I build support for sparc when I know for a fact I'm building an x86 installer? Here is how I do that manually, FWIW. (I've not run the grub2 install scripts because I haven't read them yet, which makes me nervous in a boot loader :) $cd ~/src#in my home directory, so I don't need root $tar -xvzf /usr/portage/distfiles/grub-1.98.tar.gz $cd grub-1.98 $./configure --prefix=$HOME --disable-werror $make all install At this point grub2 has merely saved some files in your home directory, it has *not* messed with your boot sector or touched legacy grub in any way. $ls ~/bin/grub* /home/wa1ter/bin/grub-bin2h /home/wa1ter/bin/grub-mkisofs /home/wa1ter/bin/grub-editenv /home/wa1ter/bin/grub-mkpasswd-pbkdf2 /home/wa1ter/bin/grub-fstest /home/wa1ter/bin/grub-mkrelpath /home/wa1ter/bin/grub-mkelfimage /home/wa1ter/bin/grub-mkrescue /home/wa1ter/bin/grub-mkfont /home/wa1ter/bin/grub-script-check /home/wa1ter/bin/grub-mkimage $ls ~/lib/grub/i386-pc/ acpi.mod font.mod linux16.modreboot.mod affs.mod fs.lstlnxboot.imgreiserfs.mod afs.modfshelp.modloadenv.modrelocator.mod dozens more grub2 modules snipped for brevity That's where the bloat comes from, as you pointed out. There are tons of those *.mod files you won't need, so the trick is to compile a list of them you *do* need, and then feed the list to grub-mkimage as described below. NOTE: I can't recall exactly why but the ata* modules conflict with some other modules, so *don't use them* unless you know what you are doing. Create a list of all grub2 modules: $ls ~/lib/grub/i386pc/*.mod /tmp/modlist Now edit that file and delete any modules you know you don't need, e.g. I deleted reiserfs.mod and ntfs.mod and the raid*.mod because I don't use those items. Don't touch anything you don't clearly recognize, but *do* delete ata.mod and ata_pthru.mod. Now it's time to build the grub2 binary executable: $~/bin/grub-mkimage -o /tmp/grub2bin `cat /tmp/modlist` Your file grub2bin is actually formatted as a tiny pseudo kernel, which your legacy grub can boot using the usual grub sytax: title try grub2 root (hdX,X) kernel /tmp/grub2bin (or wherever else you want to put it. NOTE: so far I've done nothing requiring root privileges :) That menu item will start a grub2 running so you can experiment with it all you want, but still use legacy grub to boot as you always do. (You won't yet have a menu file for grub2, so you will see only the usual grub command prompt instead of a menu.) The grub2 shell is a bit different, so you might want to type set to see what variables you can change, ls to see your disks, and of course hit the tab key when you don't know what else to type. Type help search for the real excitement. A few more grub2 differences: the 'linux' command replaces 'kernel' to load your (linux) kernel. 'multiboot' is used to load any true multiboot kernel e.g. NetBSD. Not sure, but I think you still need to chainload the Windows booter -- sadly, I can't test it anymore :D One problem I encountered on my old amd32 machine is that I had to remove the USB-related grub2 modules or grub2 would crash while probing for disks. The newer amd64 machine works fine with the USB stuff included. Dunno why. NOTE: if grub2 names your disks (ataN,N) instead of (hdN,N) that means you are using the ata* grub2 modules -- I haven't figured out how to make that configuration work yet.

I don't quite agree with Volker's viewpoint but don't totally disagree with him either. grub2 has a whole whack of bloat all of it's own. Indeed it does, except for grub.info, which is not nearly complete. Methinks a modular build system is in order here. Why should I build support for sparc when I know for a fact I'm building an x86 installer? Here is how I do that manually, FWIW. (I've not run the grub2 install scripts because I haven't read them yet, which makes me nervous in a boot loader :) $cd ~/src#in my home directory, so I don't need root $tar -xvzf /usr/portage/distfiles/grub-1.98.tar.gz $cd grub-1.98 $./configure --prefix=$HOME --disable-werror $make all install At this point grub2 has merely saved some files in your home directory, it has *not* messed with your boot sector or touched legacy grub in any way. $ls ~/bin/grub* /home/wa1ter/bin/grub-bin2h /home/wa1ter/bin/grub-mkisofs /home/wa1ter/bin/grub-editenv /home/wa1ter/bin/grub-mkpasswd-pbkdf2 /home/wa1ter/bin/grub-fstest /home/wa1ter/bin/grub-mkrelpath /home/wa1ter/bin/grub-mkelfimage /home/wa1ter/bin/grub-mkrescue /home/wa1ter/bin/grub-mkfont /home/wa1ter/bin/grub-script-check /home/wa1ter/bin/grub-mkimage $ls ~/lib/grub/i386-pc/ acpi.mod font.mod linux16.modreboot.mod affs.mod fs.lstlnxboot.imgreiserfs.mod afs.modfshelp.modloadenv.modrelocator.mod dozens more grub2 modules snipped for brevity That's where the bloat comes from, as you pointed out. There are tons of those *.mod files you won't need, so the trick is to compile a list of them you *do* need, and then feed the list to grub-mkimage as described below. NOTE: I can't recall exactly why but the ata* modules conflict with some other modules, so *don't use them* unless you know what you are doing. Create a list of all grub2 modules: $ls ~/lib/grub/i386pc/*.mod /tmp/modlist Now edit that file and delete any modules you know you don't need, e.g. I deleted reiserfs.mod and ntfs.mod and the raid*.mod because I don't use those items. Don't touch anything you don't clearly recognize, but *do* delete ata.mod and ata_pthru.mod. Now it's time to build the grub2 binary executable: $~/bin/grub-mkimage -o /tmp/grub2bin `cat /tmp/modlist` Your file grub2bin is actually formatted as a tiny pseudo kernel, which your legacy grub can boot using the usual grub sytax: title try grub2 root (hdX,X) kernel /tmp/grub2bin (or wherever else you want to put it. NOTE: so far I've done nothing requiring root privileges :) That menu item will start a grub2 running so you can experiment with it all you want, but still use legacy grub to boot as you always do. (You won't yet have a menu file for grub2, so you will see only the usual grub command prompt instead of a menu.) The grub2 shell is a bit different, so you might want to type set to see what variables you can change, ls to see your disks, and of course hit the tab key when you don't know what else to type. Type help search for the real excitement. A few more grub2 differences: the 'linux' command replaces 'kernel' to load your (linux) kernel. 'multiboot' is used to load any true multiboot kernel e.g. NetBSD. Not sure, but I think you still need to chainload the Windows booter -- sadly, I can't test it anymore :D One problem I encountered on my old amd32 machine is that I had to remove the USB-related grub2 modules or grub2 would crash while probing for disks. The newer amd64 machine works fine with the USB stuff included. Dunno why. NOTE: if grub2 names your disks (ataN,N) instead of (hdN,N) that means you are using the ata* grub2 modules -- I haven't figured out how to make that configuration work yet. This sounds about as complicated as lilo. Is this going to end up like hal? You know, so complicated that no one can use the thing and they have to start over again? Dale :-) :-)
