I was experimenting with transcoding video with ffmpeg. using the command
Code:
ffmpeg -i moviename.avi moviename.mkv
outputs the .avi into .mkv, but the output quality is very, very bad, while the original is dvd-quality.

I spent about a half hour wrestling with different website tutorials about how to convert a file with ffmpeg and figuring out how to get all the video quality options right. Then I discovered you can just use the -sameq option and it figures it all out for you if you don't want to change the vid quality but just want it in another format. Thought I'd leave this on the site in case anyone else finds himself in the same boat.

I want to edit a plist file in my friend's iPod to enable the iOS4 multitasking and homescreen backgrounds for him. I'd test it myself but I don't want to kill his iPod, and mine is already jailbroken.
EDIT: By the way, jailbreaking was made legal.

I want to know if it is possible to edit the source code of the programs in Linux. Like, take the calculator for instance. If I want to add a user-defined function to it, how can I do it - if I can do it at all? In general, where and how can I look at the source code of such programs ?

I'm looking to edit my grub.cfg file to add the "pci=routeirq" code to the kernel line so I can configure my modem in Ubuntu. I'm happy with assigning a temporary permission to myself over the root file so I don't accidentally alter it later.

I am trying to connect my 2nd Gen Ipod to Xubuntu and import my music collection onto the Ipod. I am having real problems with this. Rhythm Box does not recognise the Ipod with the plug-in, I have tried Amarok, but each time I tried to open it, it just crashed, tried sending a bug report but that did not want to work. I have also tried Exaile with the Ipod plug-in but when you go to the device manager you can click on the Ipod but nothing happens. I have tried looking at the Exaile forums but this seems to be a problem for others as well. The Ipod mounts ok, now a bit stuck.

Its a dell e510 with about a gig of ram. I'm struggling to get my ipod touch working with the gtkpod ipod manager. At this point my ipod shows on my desktop when i connect it via usb. I cannot set up the repository for it in gtkpod because i dont know the location its mounting to. if its mounting at all. so my question is. how can i tell where my ipod is being mounted? I dont have a clue what to look for in the terminal results for "df -a"
But this is what i get:
Code:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 152357444 65577992 79040140 46% /
proc 0 0 0 - /proc
none 0 0 0 - /sys
[Code]...
Edit : Itouch = first generation 8gb Edit 2: I would like to create a sticky thread that helps new users answer questions about ipods. Will a moderator please let me know what i should include in their opinion? ex. using wine to run itunes, gtkpod and how to set it up, using mm players like banshee and songbird... what version of ubuntu works best with the ipods.

I have put my record collection onto disc (Ubuntu+Audacity+Rythmbox) I would now like to play the MP3 files through my Hi-Fi. Is there a "media player" unit that can connect to a MONITOR? Note I do NOT have a TV and it looks as though these using can only connect via TV. I presume a cheap laptop would do the job but would I get Hi Fi quality sound by connecting one?

I'm a bit new in Ubuntu, but I am about to get a hang in it. I have previous use karmic koala and the version before that (cant remember the name for that) on my old computer and now I am using ubuntu 10.4 on my new computer. Ever since I installed Ubuntu for the first time, I noticed that the sound quality wasn't... the best. There isn't so much wrong with it, but like that this example. I played a FLAC file with some headphones (thru Ubuntu) and the sound quality sucked.. and then I played a mp3 file (with an ipod) and the sound quality was much much much better than the FLAC file.
I tired to play an HD movie over ....., where on Windows XP it sounds perfect, but with Ubuntu it kinda sux. The MP3 (Ipod / windows XP) is still better, than anything that is being played in Ubuntu. This is with almost every sound format I have tried. No matter if I play it with Rythmbox or vlc or some other player, the sound is wrong. I cant describe how it sounds.. but it is like it is going with a low frequency... or it is compress some how... Ever since I tried Ubuntu for the first time Ive noticed that something was wrong, but couldn't never really put my finger on it. I have dual-booted with windows XP and the sound in XP is really, really good compared to Ubuntu.

I'm trying to get the best performance/quality on my my 10.04 box and i have a few questions regarding 'sync to vblank'. My first question : I see 'sync to vblank' in 3 different locations.
- In compiz display settings
- In NVidia XVideo settings
- In NVidia OpenGLX settings
What is the difference between the 3 ?
Second question : I used to have problems watching movies where the picture seemed to be cut in half ( i'm not a native english speaker so i don't know the technical term). After reading some forums, i enabled sync to vblank everywhere i saw it. That solved the movie problem. But maybe that was overkill ?
So i did some benchmarking and noticed the following :
When i disable 'sync to vblank' in compiz my compiz benchmark drops from 60 to 30. But then my movies look worse.When i disable 'sync to vblank' in NVidia OpenGlx my GlxGears framerate jumps from 300 to 36000.I didn't notice anything when changing vsync in the NVidia XVideo setting. System specs below.
Ubuntu 10.04 64b
Nvidia GT 230 1536MB
NVIDIA Driver Version : 195.36.24

I have a friend who is using Ubuntu 10.10 Netbook Edition on their netbook and well they love it. However, I notice that at times (if not all the time) their internet is ridiculously slow. Yes, it's a 1 Mbps download connection, but I still think it's a little slow and at times I can't even get it to load a website. I'm thinking if I adjusted the MTU within Ubuntu, it might improve, if even only slightly. I believe the router is set to 1490 or 1500, I haven't really looked yet.

I have an 8Gb mkv file, which I tried to encode to avi using mencoder, it took more than 6hrs and when completed, the quality of the avi was pretty poor.Is there a way to increase the quality or is there a program that can encode mkv files? The mkv will not play on my system without stuttering badly.

my girlfriend has a netbook(acer A0751h-1401) and always complains how slow it is on vista and how much it freezes up, so i put ubuntu netbook remix on it. The video qaulity is so slow i give up and install xubuntu thinking it will be better since it is for slower computers, wrong. So im thinking it is a video driver issue or something. it has the intel gma 500 in it but it is only allowed to use 8mb of memory for video and i cant change it in the bios. I mean it shouldnt have all the lag on xubntu that it does

I am runnin Ubuntu 9.10- the Karmic Koala on acer aspire laptop. since everythin in this netbook is crap. so I hardly can see movies that so much going on in them( when so much happens, the screen freezer for a while therefore i miss the most interesting bits) I used kinda every players. the only one that works for me is mplayer since it does not require high spec it works good but it has its own costs. if I use mplayer then i have the porblem of the sound (eg i can hear stuff before it happening) I am now just wondering if there is a way to decrease the quality. I really dont care if i have great quality or not as long as i can c whats happening ( at least for this netbook anyway)

I'm still new to Ubuntu and I'm trying to get the sound working. I have a Satellite X205-SLi1 and just installed Lucid. Everything is okay, except for the sound. My laptop has 5.1 harman/kardon speakers and I think just some of them are being used and the quality is bad. I'm not sure what to do...

I've been using Windows (7) a little, and I just noticed that the mouse movement is simply infinite times better than Ubuntu's. On Windows I was able to actually "draw" things using the mouse, and it's amazingly comfortable. You actually feel on control of it. On Ubuntu I've tried to reduce the mouse polling rate to 2ms, and a number of different speed and acceleration combinations, but It seems impossible to achieve the same quality (or at least something acceptable after trying Windows).
Now that I'm used to Windows' mouse movement, I feel extremely uncomfortable and have difficult even to target links on webpages. Is there a way to increase the movement quality? My mouse is a Microsoft Basic Mouse. I'm attaching a file of a circle drawn with mouse on Windows and an attempt to reproduce it on Ubuntu.
