[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 waltd...@waltdnes.org x.gz Description: Binary data

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.

[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=1chap=12style=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?

If you get those, use e.g. k3b to rip an iso-image (or rather udf-image) of the disk, or use 'dvdbackup -M' to copy the data. 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. Using dvdbackup, dvdcpy, lxdvdrip, mplayer, tccat or so to copy only the titles that you actually want (main feature, extras, but e.g. no trailers and stuff) will be the only way.

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.

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?

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. Interesting info. Thanks. 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

Instead I do an /etc/init.d/apache2 stop; ps aux | egrep apache until I see all the threads are gone and then a /etc/init.d/apache2 start +1 If there aren't many threads a quick restart will work fine, but if there are many threads hanging around then you may be better off to stop, wait, then start. Thanks fellas, that makes perfect sense. Would it make sense for me to request a change to the initscript that waits until all threads have stopped before starting during a restart? - Grant

Michael Mol mike...@gmail.com wrote: dvdbackup can recreate the ISO images, IIRC. No, dvdbackup just creates a readable mirror copy from the directory tree on the DVD.

IIRC, some of the This is what I mentioned on the cdrecord mailing list already... 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. dvdbackup decrypts the sectors that are part of the VOB files. 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 This is interestingas some mkisofs users report that there are DVDs that look as if there is a need to introduce negative padding between some files.

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.

It was more about the idea of a fire causing the loss of maybe $15K-$20K investment over the years. I can rip all the CDs, keep the ripped version here to watch on the computer, and store the DVDs elsewhere, but that elimiates (generally) being able to watch special features which my wife and kid enjoy. I've been down this path fairly extensively. So have I. Um, if my index is right, about 1k-ish ;) 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. 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. The failure rate is way too high - even disks which burned successfully are unreadable on another PC / player. 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.
