[gentoo-user] sane cant find my scanner
I have an HP PSC 950, hplip installed and printing works. hplip online docs show that scanning is supported and that Scan supported means that PC initiated scan using a SANE compatible software application is supported over parallel, USB, or network (depending on I/O connection). sane-find-scanner reports no USB scanners found # lsusb | grep 950 Bus 004 Device 003: ID 03f0:1e11 Hewlett-Packard PSC-950 # hp-check -- | SANE CONFIGURATION | -- 'hpaio' in '/etc/sane.d/dll.conf'... OK, found. SANE backend 'hpaio' is properly set up. Checking output of 'scanimage -L'... device `hpaio:/usb/PSC_950?serial=MY27GE2065WP' is a Hewlett-Packard PSC_950 all-in-one and scanimage works. What am i missing?

I use vobcopy to rip each title to a vob (instead of VTS_${TITLE}_$n)
then 2-pass ffmpeg the vob to transcode to mkv.
Makes batch transcoding rather fast and painless.

Re: [gentoo-user] Which desktop antivirus?
I'm surprised that no one has mentioned rkhunter yet - loads of lib exploits allow system access, and there's a pretty solid argument that says that compromising a user account on the average *nix system allows enough resourses to do a lot of malicious activity without even needing privilege escalation.

My reading of those errors implies that you might have an alsa config
file left over which is confusing mplayer. Make sure that you don't
have .asoundrc or .alsa* in your ${HOME}. You probably don't need one
(not for most setups).
Is your card in `cat /proc/asound/cards` or alsamixer ? (can't check
correct location, in Windows atm).

Thanks. Here's my progress so far using a Casablanca DVD as a test case.
Again, my goal by the middle of next month is to run videos on the
Kindle Fire. The spec sheets for the Fire says it's supports mp4. I
don't see any other obvious video formats.
1) I tried vobcopy. I got 6GB of files. I assumed ffmpeg was the next
step but didn't easily Google how to run it in this specific case so I
set it aside for the moment.
2) Tried dvd::rip because it was in portage. It got through the rip
portion of the job but then apparently couldn't find it's own files to
do the encoding. I tried joining the dvd:rip email list but I'm still
waiting for the moderator to accept me 3 days later so there's no
where appropriate for me to ask questions on using dvd::rip.
3) I tried handbrake which requires using an overlay.
3a) Tried the sabayon overlay but it wants to change too many files on
my system so I dropped that.
3b) Tried the multimedia overlay because it had the most up to date
version of handbrake. Unfortunately that didn't build
3c) Tried the init6 overlay with provided handbrake-0.9.5 which built
correctly and runs fine.
Handbrake goes directly from DVD to a reasonably sized (1.3GB) m4v
file. That file plays fine in xine and looks very good. Being that the
Kindle Fire only has about 6GB available for user content that gives
me 4 movies at a time which is fine for me but I suspect I can do
better.
My issue now (I think) is to learn to use ffmpeg to convert from m4v
to mp4. I'd like to see about reducing the file size a bit if
possible. At the same time the native resolution of the Fire is
1024x600 so I'm wondering about whether I can make the movies look
better by making the mp4 file somehow know about that size.
Anyway, I'v made reasonable progress for a few days of sporadic
effort. Hopefully I'll be able to make more by Nov. 15th.
Cheers,
Mark

From the Handbrake manual: [quote] MP4 vs M4v They are the exact same file, the only difference is the extension. MP4 vs M4v. For MP4 files, HandBrake will automatically use the extension M4V when you pass-through audio (AC3), use SRT subtitles or have chapter markers enabled. You can simply change the file extension between .mp4 and .m4v as the file is exactly the same. There are no differences in the content or container itself. You can disable the option to automatically set this in HandBrakes preferences. [/quote]

If you mean you want the files encoded at a resolution of 1024x600, you can tell handbrake what output resolution you want. You'll get far better results by encoding to the desired resolution, format and bit-rate you want the first time than you will re-encoding a second time. You can create your own presets with whatever encoding settings you want. -- Grant Edwards grant.b.edwardsYow! World War III? at No thanks! gmail.com

Was your vobcopy line $vobcopy -i /path/to/mountpoint -n ${TITLE_NO}

My ffmpeg lines for dvd to mkv:
2.0 audio:

-pass $a -vcodec libx264 -b 800k -deinterlace -acodec libfaac -ac 2

Downscale hd to 480p and de-interlace DVDs and other 480i content.
720x480 will look pretty good on a 1024x600 (WSVGA) screen.
