I have long had my own extra var-type dir, which i call '/z' (it started out as "all the otherwise unassigned space on the disk"). Currently, it has 20 GB , of which 8 GB are used, all temporary stuff, none of it for anything of lasting value. That's where I do all my heavy-lifting, eg ISOs, testing packed archives & esp /z/tmp , which is my Portage tempdir. In your set-up, you might consider mounting /dev/sda8 as a similar big dir. That would avoid all the problems of changing existing dir sizes & also any need to alter LVM. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

[gentoo-user] Any video optimization tips?
I'm trying to make an older PC display high-def streaming video. It's a Dell Inspiron Desktop 530, with 2 gigs of ram, assembled and shipped August 2007. It has an Intel dual core (*NOT* a "Core Duo") cpu like so (from /proc/cpuinfo). vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Genuine Intel(R) CPU2140 @ 1.60GHz stepping: 2 cpu MHz : 1595.660 cache size : 1024 KB The original Intel onboard GPU wasn't really up to the task. I bought an Nvidia GeForce 6200 video card, set it up, and it handles 1280x720p video OK, from my HDHomerun TV tuner box. 1920x1080i shows the occasional hint of stuttering. I followed the instructions at http://www.gentoo.org/doc/en/xorg-config.xml including the Nouveau driver. I'm running ICEWM to minimize system overhead. Are there any other tips and tricks for getting better video performance out of this admittedly old system? glxgears shows 382 fps when the system is idle. It works without an xorg.conf. This also happens to my mdev test machine (no udev). I'm attaching the Xorg log file for more detail. -- Walter Dnes x.gz Description: Binary data

E.g.: mkdir /mnt/sparespace mount /dev/sda8 /mnt/sparespace mount -o bind /mnt/sparespace /var/tmp/portage Of course, this assumes sda8 has enough space for heavy compiles (i.e., 10 GiB or more). Create a huge number of inodes or use a filesystem other than ext[2-4] for sda8, and you're covered. Rgds,

Additionally, when I use older machines, sometimes minimization of the compile flags helps on some apps and not on others. You have to experiment. It usually works for machines that are design for a single special purpose, not workstations or every server service you can compile for. I never optimized one for just streaming video, so I cannot give you specifics. Here is one I use for a firewall. Note the CFLAGS (Os) setting for small: CFLAGS="-Os -march=i586 -pipe -fomit-frame-pointer" USE="-* -nls mmx hardened ncurses ssl crypt berkdb tcpd pam perl pcre \ python readline zlib bzip2 nptl nptlonly syslog" Find the minimal flags and the optimum CFLAGS settings for your needs. Refine by testing. USE a fast hard drive. Avoid apps that soak up ram. Some video apps are ram_hogs... I'd be curious to learn what you finally figure out. hth, James

I've got two GeForce 210s which I purchased because A) they were $50/pc two years ago, and B) they did exactly this. Then enable vdpau. (But that means running the proprietary drivers, disabling KMS, disabling NOVOU, etc) Then use any media player with support for vdpau. I know mplayer will do it. I'm unsure about ffmpeg, flash, etc. With an (old) $50 card, you can get an old Core 2 desktop system to serve as an HTPC. -- :wq

[gentoo-user] iptables question...
Hi all, I was reading up on some iptables rules in the gentoo security handbook: http://www.gentoo.org/doc/en/security/security-handbook.xml?part=1&chap=12&style=printable It mentions DROPing packets with an INVALID state. It sounded/sounds like a good idea, so I added the following rule: -A INPUT -i eth0 -m state --state INVALID -j LOG As suggested, I addd this rule just ABOVE this one: -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT I also changed the DROP action to LOG so I could see what it did if anything. Right after adding this rule, I started seeing lines like this in the log: Dec 16 10:15:31 myhost kernel: IN=eth0 OUT= MAC=00:e0:81:54:9c:8a:00:90:7f:86:a8:c0:08:00 SRC=208.87.137.233 DST=192.168.1.252 LEN=40 TOS=0x00 PREC=0x00 TTL=52 ID=0 DF PROTO=TCP SPT=50113 DPT=25 WINDOW=0 RES=0x00 RST URGP=0 What I don't understand is why it isn't using my LOG prefix that is used for everything else: -A INPUT -j LOG --log-prefix "(>fw-drop): " --log-level 7 Anyone?

I did exactly the same thing a few years ago, but it's been a long, long time, so my memory on my process is very fuzzy. (It also involved my first foray into RAID...I've got a couple hundred DVDs!) Go ahead, count the number of times I qualify something with "IIRC"... dvdbackup can recreate the ISO images, IIRC. If you run a simple 'dd' on a DVD with encrypted portions, you'll get I/O errors when it encounters the encrypted pieces. IIRC, some of the data required to decrypt those portions is on the disc, but it's in an out-of-the-way portion that won't show up as part of the block device. IIRC, dvdbackup makes use of libdvdcss to decrypt the encrypted portions[1], and writes a decrypted version of the data. *this* is why you can't make a bit-for-bit copy; the output data would be decrypted. There are other, later obstacles, too; once CSS was broken, some content publishers (Bandai USA, for example) would fudge the ISO spec and the DVD nav specs in ways that didn't break *most* hardware DVD players, but did tend to break players which strictly adhered to the standards, such as ffmpeg, vlc and mplayer. It also broke dvdbackup for me, IIRC, which is why I had to resort to vobcopy in some cases. I expect the software angle for handling these things has gotten better, though. [1] I don't know how it does it when dd would have hit an I/O error. Obviously, my understanding of the workings of dvdbackup, dd, DVDs and CSS encryption is flawed somehow. -- :wq

It could be apache configuration, but I don't see how? Wait. Stop. This is your (first) problem. Use Ledger-SMB. The security vulnerabilities have demonstrated that Dieter cannot be trusted.

No it doesn't. You can use dvdbackup (or k9copy or ...) to copy the DVDs to the computer and when you play them back you get all the menus and special features and whatnot. If you want you can create ISO images and burn them to dual-layer-DVDs, but you don't need to do that to play them with all the features. -- Grant Edwards grant.b.edwardsYow!

Have a tail -f on the messages, you can't use dd / ddrescue / dd_rescue if you get stuff like this in the log: kernel: [17700.04] end_request: I/O error, dev sr0, sector 252120 kernel: [17700.131687] sr 16:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE kernel: [17700.131698] sr 16:0:0:0: [sr0] Sense Key : Illegal Request [current] kernel: [17700.131707] sr 16:0:0:0: [sr0] Add.

There's some "broken" disks though with intentional defects in the filesystem etc., often from Fbal. You usually won't be able to copy those "whole" and images witk k3b will probably be defective.

I've been down this path fairly extensively. Use media-video/dvdbackup and mkisofs (from app-cdr/cdrtools) to create .iso images of your DVDs. Store these on a Samba share, then use something like the PlayOn HD Mini or the Western Digital TV Live! to watch them on your big screen TV. These players allow you to treat .iso files on the network just as if they were actual DVDs and give you full access to the menus and extra features. I'm in the process of trying media-tv/xbmc instead - I believe it handles menus, but haven't got far enough to test that (I just got video sorted on my HTPC, now working on sound). dvdbackup will fail on a small number of DVDs which have been "copy-protected" by making them non-compliant with the DVD specification (IMO this is fixable in dvdbackup's code), but I'm getting at least a 95% success rate. I have found writing dual-layer DVDs practically impossible. The failure rate is way too high - even disks which burned "successfully" are unreadable on another PC / player. Stroller.

Now we can become Hi Grant, I should have guessed you'd be on top of this subject given your pointer a month ago about Handbrake. (Which has been a really great program.) Thanks for that and thanks for the additional info. So for my continued education, if I take an encrypted movie I can use program XYZ (Linux or Windows-based...) to create an iso image, but that iso image won't, even if it does include all the special features, ever be a bit-for-bit copy of the original. It's now unencrypted and created anew. It's a completely different way to represent the original data. That said, if it's a _complete_ representation of the original then the special features are there, and if written to a DVD _might_ work in my DVD player, assuming the DVD player isn't specifically looking for something that was on the original disc such as specifically encrypted blocks of data, etc. Am I getting closer? Thanks, Mark

Some time back, I was almost ready to do something big on my 1000+ dvd collection. I did a lot of research. I got stuck on the raid servers and then abandoned the project. I'm building a new office and stuck in brick and mortar at this time. STROLLER has tried everything and knows what works. He has some very cool scripts (I bet he'd share, if you ask him) I'd strike up a conversation with Stroller. When I get back to it, I was going to also put the great information into a wiki for many others to useas I think there are many Gentoo'rs that have similar needs and desires. Stroller knows his stuff on video, because I think he has tried every piece of software and reproduction scheme you can imagine... (um, I mean related to video). ;-) hth, James

My new TV actually has a number of USB ports and I've managed to mount a USB disk with mp4 files created by Handbrake and play them just fine. I hadn't considered trying an iso file though. I'll give that a shot this weekend and see if it sees them. Unfortunately *.iso isn't on their recognized formats list, but it's worth a try. The nice thing about the TV is that it has lots of Open Source software built in and puts of nice folders showing the directories I've created and all the files in each directory. I'm currently experimenting with how much I can tolerate in terms of compressing the DVD info. I'll certainly look into dvdbackup. I tried to emerge it but I've gotten some sort of package block going on that portage isn't happy about. Thanks, Mark

Dual layer DVDs will only work, if the layer break is at the right place. I so far have not been able to get the layer break value from the IFO file. You need to use cdrecord -atip to get the layer break value and then use cdrecord layerbreak=# and a DVD+R/DL media.

It starts with the Geforce 8400 series. As I mentioned in another post, -march=native does not enable mmx, sse, sse2, sse3, and ssse3 options for gcc.

There's DVDs that look (to e.g. lsdvd) as if there were ~60 Tracks of various sizes used, with a playing time of, say, 40 hours overall, breaking the Specs willfully. Of course, only e.g. 4 Tracks are the "real" tracks. Figuring out which tracks those are (e.g. playing the disc with xine, mplayer or vlc) and then extracting only those tracks with e.g. dvdbackup is the only possibility. Images etc. will be defective. Don't ask me how you create such interleaved tracks (e.g. tracks 20-35 would be various parts of a series episode but only one, say 27, would be the full track). I'd guess "negative padding" (at least in the nav-structures) might play a role there. Just this week I've had a DVD, where lsdvd just barfed. The image with k3b was broken. dvdbackup for single tracks worked. That's one reason I like to rent a disc before I buy a whole series. Actually, there's only one Movie-set that has broken (one or two out of 5) discs, most I own are standard conforming and some seem to not even bother with css. "Digital files cannot be made uncopyable, any more than water can be made not wet." --Bruce Schneier on `copy protection' schemes And I want to make backups of the discs I own. The less hoops I'm forced to jump through (with a rented disc), the more likely I am to buy something. There's a certain series (c.f. above) I quite like, but the DVDs are just plain broken. Won't buy. Period. -dnh, got to look up the publisher on above mentioned disc where lsdvd barfed ... ah: Cnenzbhag. I hadn't have them on my "publishes un-DVDs" list yet. Well, anyway, some publishers seem to start not to produce un-DVDs lately. Just keep sending rented disc after disc back as "broken" and asking for replacement ... -- >> Take two Gods. >Diagnostic. n. Someone who doubts the existence of two Gods. Makes sense.

At least mplayer, vlc and xine will also happily play a directory, be it a mounted DVD, a mounted image or just a rip as made by dvdbackup and others (e.g. lxdvdrip). >dvdbackup will fail on a small number of DVDs which have been >"copy-protected" by making them non-compliant with the DVD >specification (IMO this is fixable in dvdbackup's code), but I'm >getting at least a 95% success rate. See my other mail(s), finding the correct tracks with above players and then ripping only those tracks with 'dvdbackup -t TRACKNO ...' should get you to 99.5% or so. The rest is usually just plain broken. So far, I've always got a result out of non-physically-defective disc (I don't mind throwing away the menus though). I even had the situation that trying to only play one such disc (with xine IIRC) made my box hang up. Needed a hard reset. Weirdly enough, I could still rip the tracks after the reboot with dvdbackup or so and the result was ok ... Probably the (libata) IDE driver got thoroughly screwed on that first try by whatever combination of commands and drive reactions... >I have found writing dual-layer DVDs practically impossible.

I've, so far, only written data-DVD-DL, no problems with those ;) BTW: do you reencode stuff? I use mencoder with: -x264encopts crf=22:trellis=1:qcomp=0.8:weight_b:8x8dct:subq=6:nr=750 the resulting files are usually surprisingly small and still have a very good quality (I can't see a difference to the original with both unscaled on the screen (PAL-DVD, not HD ;). I have yet to try that one on some difficuly cases though (dark scenes in a movie with fog, panning, and movement and a quite noisy-in-the-dark series (SG-1/S1). Might have to break out hqdn3d again for the latter. -dnh -- Rincewind shut his eyes.
