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.

I am currently working on a large document using LATEX and have bumped into a problem. Here is the thing: I write this document in several machines, there is a Mac at school, some Ubuntu based machine, and this Fedora 12 x64 laptop. The thing is that I compile the document periodically on these machines and I WOULD expect the results to be similar, but they are not because the resulting PDF is of inferior quality! (fonts do not look very well when they are zoomed in).
Mac OSX's latex-produced-PDFs are of higher quality than their Linux counterparts. Is there something I can do to fix that? Install an extra package perhaps?
The quality of sound I am getting is very poor with lots of noises.I'm using openSUSE 11.4 on a DELL Inspiron 6400, and the sound is "82801G (ICH7 Family) High Definition Audio Controller".I have tried removing pulseaudio but it did not change anything.I had no problem with the sound on 11.2 and the quality of sound is normal on Windows.

View 2 Replies View RelatedUbuntu 10.4, Sound card works great when recording and doing playback with Ubuntu. Skype v. 2.1 beta. In Windows XP, same system, I dual boot. When I use Skype (latest), and I try to call to a landline in the US, everything works fine. Everyone can hear me fine and there's no problems. The problem: When I use Ubuntu, and Skype, there's crackling, dropped off sound, and the overall quality is bad.
EDIT: The biggest issue here is dropping parts of the call. Why does it do that?

View 7 Replies View RelatedI got a 5.1 desktop sound sys for my recently built gaming rig. It sounds great. On Windows, that is. In ubuntu when I'm playing music, primarily when the subwoofer plays the bass, the speakers sound like they're farting and ripping phone books in half. Also, they get very statticy and sort of quiet. In sound preferences, analog stereo duplex is selected, if that's of any value. How can I get good sound playback in ubuntu?
View 1 Replies View RelatedAfter taking a first look onto internet under Fedora linux (using Firefox web browser) I've saw that every single image is displayer much much worse than in same Firefox under Windows. Especially when scaling, it became pixelized, but even without scaling it is smoothen very much. I've checked Konqueror but quality is bad too and the same as in Firefox. What could be the reason and how could I fix it?
BTW, everything in linux GUI looks a little worse, including font, etc, looks smooth. Images under IrfanView too, but not as bad as in browsers. Proprietary Nvidia driver from RPMfusion is installed and 3D works. But running Fedora under VirtualBox in Windows produce same bad quality as in native Fedora.
I'm running -current (13.37) 32 bit and have installed OpenOffice 3.2.1. The problem is the menu fonts in OpenOffice which look very thin and are not smooth. All other application fonts look very good. When I had this same version of OpenOffice installed on Slackware 12.2 I did not see this problem.In OpenOffice I have ticked the option to use system font for user interface but this doesn't seem to have any effect. I've also ticked the screen font anti aliasing option because the fonts look worse when this is not ticked. My KDE system font is DejaVu Sans, the same as it was on Slackware 12.2.
My OpenOffice package was built using a script written by Robby Workman which I think I got from his web site a long time ago. It takes the rpms and creates a Slackware package.

I have recently switched from suse 9.2 32-bit to 11.3 64-bit (luckily I'm still mantaining the old machien for a while).I'm noticing that the graphics quality of the applets displayed by the new firefox (3.6.12 bundled with the opensuse distro) is significantly worse (mainly concerning fonts which look very poor) then the one I used to have on the old system.I see that the new firefox uses IcedTea 1.9.2. The old system was using, I guess, something called libjavaplugin_oji.Is this a known problem with IcedTea and is there a recommended replacenent ?
View 2 Replies View RelatedI installed openSuSE 11.2 sometime ago in a COMPAQ Presario CQ60-419WM laptop (the ones that Wal-mart sold for $300 about a year-and-a-half ago. I installed the 64-bit version because I saw that the processor could support that (perhaps that was not a good idea). I have some problems that seem related to not having the necessary drivers. My wireless has never worked and my display is far from what I would like it to be (the response is slow, if a drag a window, its motion is jerky, if I scroll down in a browser window, the motion is wavy). The look and feel is very different from what I get at work and I do not know how to fix it.

My laptop is a Dell Inspiron 510m with onboard Intel 855 sound (STAC 9750 AC97). The sound was perfect with WinXP, but with Ubuntu it's tinny and lacks richness and vibrates and distorts at higher volumes. I've played around with Alsamixer and changed the driver from ALSA to OSS4 and it has improved slightly, but still not perfect. Is it just not gonna get any better, should I not be expecting it to be as good as WinXP?
I've seen on the Intel site a Linux driver for my controller, it's a tarball but it won't compile after extracting it (read on this forum that someone had the exact same problem with that driver). Will the Intel driver not help, does the problem go deeper than just the driver? It would be perfect it you could just wrap the Dell/Intel driver and use that (just like with wireless ndiswrapper).
I just got my hands on an MSI E7235-295US and slapped Ubuntu 9.10 on it. So far everything's worked great, but I am beginning to get a bit concerned about my sound quality. The laptop itself has 5 speakers + subwoofer so I should be getting 5.1 sound, if I understand things correctly (the newegg link should provide more details) and when I play anything (music, flash, videos, games, etc...) the sound comes out 'muffled'. Almost as if it is in a concert hall, maybe. I initially wondered if the problem is related to the 5 speakers and if the sound is initially only setup for two. If that is the case, nothing I've done has seemed to made any real difference. I've tried changing the master/pci channels, but it only hides it a little, and doesn't solve the problem.
This seemed to be on the right track, but the laptop is still really new and not listed in the alsa file.

View 2 Replies View RelatedA recent update to ffmpeg, in which I've learned was an upgrade to the restricted ffmpeg as opposed to the unrestricted default one that is in the official repos, has now made it unable for me to use mplayer or Devede. Reading up about this, especially from here: [URL].. I have learned it's a frequent problem when installing the restricted ffmpeg. Basically what Devede says at startup is:
Code:
Cant's find the following programs:
mplayer
mencoder
Devede needs them to work. If you want to use Devede, you must install all of them. Using the terminal to open mplayer (or mencoder), I get this error: mplayer: relocation error: mplayer: symbol codec_wav_tags, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference From my research, seems as though the problem lies in libavformat52 not being installed (or removed) and libavformat-extra-52 is installed, which is the same thing, but because it's the restricted version, it is called something different. Anybody know if that is correct?
Also, checking up, libavformat-unstripped-52 isn't installed but available, so should I install that to replace the missing libavformat52, as when I sudo aptitude install libavformat52, it says it conflicts with libavformat-extra-52?
I installed libavformat-unstripped-52, which didn't conflict with the already installed libavformat-extra-52, just to see if it would basically just replace the missing libavformat52, which conflicted with libavformat-extra-52 and couldn't be installed safely, but after I did, nothing changed. I still get the same error with opening Devede and mplayer (or mencoder) in the terminal.
I'm trying to convert a video in .ogm format to .avi format so I can stream it to my PS3 via uShare. I'm using Mencoder and the following command to do it (to transcode the audio from vorbis to mp3 and the video from mpeg4 to xvid):
Code: mencoder input.ogm -oac mp3lame -ovc xvid -xvidencopts pass=1 -o output.avi.The only problem is, the video contains 2 audio streams - one Japanese and one English. Needless to say, I need the English one. The above command only seems to transcode the Japanese audio though!Here's what ffmpeg has to say about the input file:
Code:
Input #0, ogg, from 'input.ogm':
Duration: 00:24:16.12, start: 0.000000, bitrate: 1280 kb/s[code]...
what I can do to specify the correct audio stream to encode? Also, how can I keep the bitrate the same as the output.avi seems to default to 96kbps?I'm not sure which audio stream is which but a little trial and error will sort that out in no time.

So I typically use cat to put my avi files together.. but today I figure lets see about ripping over so I can watch on my Droid.
As nobody has a xvid or vlc player on the droid (yet.. coders are doing alot for Android ya know) I will have to convert the video down and change the format.. So.. can anybody tell me a mencoder command line directive to get as close to this as possible (I found ipod settings leave the actual video lacking).

I'm doing a little python app for encoding .avi from dvds. I know there are a few really good applications out there that do the same thing but I wanted something simple with less faff. The application has 3 settings: Fast, Medium, and Slow. These are for the varying quality rips. For file format I was thinking either lavc or Xvid.
So my first question is, which is better? I really don't know anything about it and I haven't found a decent site that compares them. And secondly what are the best settings for a DVD rip for a Fast Rip, a 'Best of Both' Rip, and a Best Quality Rip? If I've missed any factors in this, please let me know, I'm new to the DVD ripping game. I have no intentions of distributing the movies, they are for my own uses.
I'm trying to convert my screencast to an .avi file, but when I open it... the commentary track is waaay out of sync. No matter which codec I use, it will not stop dropping frames!
