Ubuntu Multimedia :: Prepare Large Amounts Of Images For Web?
Oct 27, 2010
I've been using GIMP's 'save for the web' tool to reduce the file sizes of images.
I now have a directory with about 50 images. I'd like to avoid processing them all by hand.
I have a (very) basic knowledge of programming, and I'm comfortable with the commandline. I don't mind doing some homework on how to use new tools.
All I'm really concerned with here is reducing the file sizes of the images I have.
What possible pathways are there for me to prepare large amounts of images for the web?

i have a car stereo that reads a USB drive with all my music on it, however to sort through the music it uses a method of finding folders containing music, then displaying them all in a list. i find this interface annoying because in order to sort the music by artist i have to go and manually move it out of the album folders by hand, this takes a long time for 11+ GB of music so i was trying to use the linux CLI to quicken the process. use a command like this
Code:
mv /media/usb/music/*/*/* /media/usb/music/*/
but for some reason this moves all my music into the last folder alphabetically in my drive, the music is all pre-arranged like this /media/usb/music/artist/album/song

Are there any tools out there that let me select a bunch of data and burn it to multiple cd's or DVD's? I'm using k3b but have to manually select cd and dvd size amounts.

we've been trying to become a bit more serious about backup. It seems the better way to do MySQL backup is to use the binlog. However, that binlog is huge! We seem to produce something like 10Gb per month. I'd like to copy the backup to somewhere off the server as I don't feel like there is much to be gained by just copying it to somewhere else on the server. I recently made a full backup which after compression amounted to 2.5Gb and took me 6.5 hours to copy to my own computer ... So that solution doesn't seem practical for the binlog backup.Should we rent another server somewhere? Is it possible to find a server like that really cheap? Or is there some other solution? What are other people's MySQL backup practices?

We're load testing some of our larger servers (16GB+ RAM), and when memory starts to run low they are kicking off the oomkiller instead of swapping. I've checked swapon -s (which says we're using 0 bytes out of 16GB of swap), I've checked swappiness (60), I've tried upping the swap to 32GB, all to no avail. If we pull some RAM, and configure the box with 8GB of physical ram and 16 (or more) GB of swap, sure enough it dips into it and is more stable than a 16GB box with 16 or 32GB of swap.

I have a few hundred images of 30000 x 10000 pixels in size. Each image has lots of text (rendered as pixels) on it. I'd like to translate all text to another language. I speak both languages, and it's fine for me to translate each phrase manually. I need an image editor which can open these images quickly (faster than Inkscape, which needs about 60 seconds to open such an image), lets me zoom and rotate by 90 degrees, lets me erase (i.e. change the color of a selected rectangle to solid white), lets me add text, and lets me save the file as quickly as possible. I'd like to minimize the time I have to wait for the software to load, render and save images. Which is the best program for that on Windows? On Linux?

I just installed Kubuntu 11.04.
I ran VLC and it brought my PC to a halt.
I attached a picture of memory usage from htop.
Why do you think VLC is using so much system resources?

my mythfrontend make a horrible pop when opening a av file no matter what app I use. I have edited the last 2 lines in /etc/modprobe.d/alsa-base.conf as per[URL].. and it has reduced by not doing it when I change channels but when I close and open myth or xbmc or vlc it still does it? I am using a 5.1 surround system connected by 1/4 inch plugs and rca adaptors I dont know how to configure alsa for 5.1 either? as The volume levels are not there ike in my other pc's however windows runs 5.1 on the same pc perfectly I think it has something to do with the duality of the plugs (ie they can be line input,micropone input or subwoofer output,centre speaker s urround left and surround right.

im running ubutu 9.10 with the standard nvida proprietry drivers as a media center. the output is over hdmi, through a a/v reciver and onto a lcd television. my proble mis that the output is too large for the screen even whan outputting at a smaller resoultion than the native resolution of the television. this means that the top, bottom, left and right of the output is chopped off. in windows i can adjust the size of the output useing some sliders to get the image to fit the screen. however these are only available in the windows drivers and i cannot find a substitute in the ubuntu ones. one way of doing it may be to output black bard at the sides of the screen but i have no idea how to do this.

I am configuring an ubuntu system for a friend of mine, he is Arab and he used to watch (with windows) the films on this site: [url]
I tried to open the site with firefox but I cannot see the image on that page, I see the cursor changing shape and clicking with right button in the properties I see they are gif images, furthermore clicking on the (not displayed) images should open a link to the film but instead a blank page opens with error.

I'm running Ubuntu 10.10 with an NVIDIA GeForce 6100 video adapter and my monitor seems to flicker whenever the the computer is processing. My system is up to date and I did install the recommended NVIDIA driver. The monitor isn't going blank or anything like that, it just seems like every once in a while different images will pop up for less than a second. Any ideas as to what the problem might be? I've attached a copy of the xorg.conf file as well:
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection

I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.

What would be the best music jukebox that doesn't lag when there is a lot of music in the library (400+ gigs)?
I have tried songbird, but its pretty laggy. I like to import all my music and turn on shuffle and go through my songs.

Is there a Linux app for mounting and playing audio CDs from image files? I have saved disc images of nearly all of my CD collection, but I have yet to find any convenient way to play them.
Because of the nature of CD audio, every CD image has an accompanying .cue file, so there are actually 2 files (*.iso or *.bin and *.cue) from each disc. VLC Media Player will play DVD .iso images directly, but doesn't know what to do with audio CD images (or the .cue files).
Mounting and unmounting the images at the command line is tedious, given the very long file paths. I'd rather have a GUI-based app. Does any such thing exist for Linux?
FWIW, Acetone ISO doesn't work. It doesn't want to mount my *.iso format CD images. Probably some funkiness of the CD audio format. I think it is what the Acetone devs call a "multi-sector image." Likewise for the *.bin images of CDs.

The company that I work for has massive amounts on our file server and that amount continues to grow. What we are looking for is a search appliance that will make it easier to search all documents on the file server and also search the content of those documents. I don't really like the idea of everyone using an app like X1 and searching the share drives that way on their individual PC. I would like a search appliance.

I just burned a copy of a DVD.
Great. Now, will I be filling up my hard drive every time I do this? Where does Brasero keep the images that it makes of DVD's and CD's when it copies?
I would like to delete them, after I copy an image...

I'm trying to setup MythTV, but whenever I do so, I get no text on the X window setup screen. The language selection takes a very long time (input is super delayed) and I don't see anything on the screen. This last time I ran it it went the farthest it has gone before, but it always hangs at the theme file selection, as shown by this Terminal output.
Code:
Loading window theme from /usr/local/share/mythtv/themes/Terra/menu-ui.xml
Loading menu theme from /usr/local/share/mythtv/themes/defaultmenu//mainmenu.xml

I have a bunch of images I took of the same thing, but I was holding the camera, so each one moves a little bit. Is there some way to crop the images so that the focal point doesn't move between pictures?I've done some searching but I haven't had much luck finding anything.

I have a Sony Bravia TV (ex700) that has DNLA support (spotty at that from what i've read). What i'm wanting, is the ability for a DNLA type device to stream my ISO images (dvd images).So far I've tried Mythbuntu and have had some issues with it. Biggest issue is that the DNLA server does not show up on my sony. Other issues are around iso images playing faster than normal (through the host, not DNLA).
I've also tried minidlna but there appears to be no support for ISO files.At this time, all i want is a linux based DNLA server that supports ISO files.

i have no problem. But with user2, when i start to read a video file, i have no image, just a black screen.The sound is ok, the time is running normally, but no image. *It tested with vlc and gnome-media-player, it is the same. *I have no error message, when I start the program in a console. *I suspected a permission problem, and i checked all the groups, but i don't see any difference between user1 and user2.

I have a very big image directory: One image per minute, whole a year, captured from a webcam. Now I want to make a video (15 or 24FPS) with all the webcam captures, to see how it changed during this period. I've tried automotion, but it makes a very low quality video, besides it blocks with lots of images. I've also tried dvd-slideshow, but it's not possible to make a more-than-1FPS video.
I also need to change the date in each webcam's images, because they are wrong, so it needed to overlay a little layout with the right date for each image, is that possible to manage within some application? Preferibly shell applications which supports lots of Gb of information (anyway I always could make little videos and then glue them)
