Ubuntu Multimedia :: How To Decrease The Graphic Quality
Sep 20, 2010
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 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'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 downloaded an HD video from ....., but my computer is not powerful enough to play it. Is it possible to convert it to standard quality in Handbrake? If not, what video converter would be best?

I am trying to use ffmpeg to split a number of videos of different types (WMV, MPG, AVI). I do not want to change anything else, just split them into smaller chunks. The video is split, but the quality of the output file is terrible. I would describe it as "blocky" (I think the correct term is "pixelated"). When I make the player (KMPlayer) much smaller the problem naturally goes away.
The command I am using:
ffmpeg -i original_vid.wmv -ss 00:00:00 -t 00:05:00 first_vid.wmv
The output:
FFmpeg version SVN-r19352-4:0.5+svn20090706-2ubuntu2, Copyright (c) 2000-2009 Fabrice Bellard, et al.
configuration: --extra-version=4:0.5+svn20090706-2ubuntu2 --prefix=/usr --enable-avfilter --enable-avfilter-lavf --enable-vdpau --enable-bzlib --enable-libgsm --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis
[Code]....
"Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 25.00 (25/1)
Seems to mean something, but I couldn't find anything saying that this is the problem or what O should do to correct it.

I have a 500MB video that is 720x400. I want to half the size of the video while retaining the same relative quality.My main goal is to half the filesize of the video, but to do that and keep the same relative quality I will have to also make the resolution smaller.I can't seem to find a way to do this.I would preferer to use ffmpeg, but any solution would be good at this point. I would really like to be able to do this from the command line, but if there is a gui program that will also give me the command line it uses, that's great too.Does any one know of a way to half the file size of a video while maintaining the same relative quality?

I am looking for a good mp3 player. I obviously dislike apple n windows so I wont buy an iPod or Zune player. Now I am wondering if any of you had good experience with any other mp3 player on Ubuntu. The two things I want are firstly a product of high quality n functionality like those two mentioned above AND secondly a seamless ubuntu compatibility. I'd love to see synchronization and stuff working out of the box. Anyone out there found a outstanding product and like to give a recommendation?

If I were to take a flac music file and convert it to alac using ffmpeg would there be any degradation of audio quality? I am also wondering how many people are actually able to tell the difference between a high quality MP3 and a lossless file. If I were to find a suitable place to upload a load of different files would people be willing to judge the audio quality?

When I watch movies on Ubuntu I noticed that quality of reproduction is not good as in Windows. All movies seems to have some sort of contrast problem which I don't know how to fix. This problem is not present in Windows (XP/7) and stand-alone DVD players play them also correctly.
Here are images (AVI, DivX format)
Windows version: http://i52.tinypic.com/125hlis.png
Linux version: http://i56.tinypic.com/tz53t.png
Also here is MKV format which is noticeably even sharper in Windows:
Windows version: http://i53.tinypic.com/2lmqxqe.png
Linux version: http://i53.tinypic.com/15gfmlt.png
Note: I didn't wanted to include them in post since they are quite big and I didn't want to do JPG compress since they might lose quality. Try not to resize them.
On Ubuntu I installed some 'extra' codecs (might be proprietary) via Software center. I use standard movie player that comes with 10.10, but for MKV I use VLC since mkv don't run in standard movie player. On Windows I use k-lite codec pack and GOM player. My guess is that Windows solve those sharpness and contrast issues by using some playback filters (possibly contained in k-lite codec pack) that are unavailable in Ubuntu. I installed proprietary video driver for ATI RADEON 2600.

With Banshee, I am easily able to put music onto my iPod and have it convert my FLAC to something that the iPod can read. But is there a way to control the quality of the conversion. I don't really want my FLAC to go down to like 192kbps. Are there any settings that I am missing or any files that could be edited to make this happen?

I hooked up my laptop via monitor cable to the L.C.D. T.V. and ran a patch I found on Ubuntu forums because it wasn't showing up on the T.V. After that it asked me what screen resolution I wanted I entered it and then the screen worked! However, now when I play movies on either the T.V as a monitor or just on the laptop itself it comes out with bad video quality now. It sucks because that was the purpose of hooking up my T.V. as the monitor was to watch movies and videos I have downloaded.

Ubuntu 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?

Is their any software in Linux which tells about audio sound quality (frequency,bits/s etc...?
which is special designed for all Audio_quality-features. Moreover, I have tried Themonospot software but its only for Video formats. I want soft 4 audio formats only.

I 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?

I installed Ubuntu 10.10 recently and I love it. Everything works great except for video playing. When I try to play DVD's with VLC or ANY video player, I get horizontal flickering and I can't seem to fix it. I re-downloaded and installed the most recent video drivers from Nvidia and it did not change anything.
My video card:
Code:
I don't know what else to do. When I run windows, the videos play smoothly, just fine. But when I play the same DVD's under Ubuntu, it's choppy.

I have used abcde with lots of success in the past and I always grab the a config file off the net (I think andrew's web page or something).
Anyways, I went to rip a few cd's to OGG today and my quality setting is: OGGENCOPTS='-q 6' but when I play the ogg's (using audacious or gnome player) the kbs always shows 112. I know OGG is not a bitrated encoder, but rather uses quality levels 1-10 (I think?), but I always got ~192kbs using quality level 6, but now it does not seem so.
Anyone know of something I might be overlooking her, perhaps something not quite set right... here is the confg I am using in my home dir... actually I did notice there is an /etc/abcde.conf file, but all options are commented out. I wonder if perhaps there is another abcde.conf file being used somewhere and not the one i created in ~/.abcde. I think that is how the file should be named; does that look right does anyone know?
Code:
# -----------------$HOME/.abcde.conf----------------- #
#
# A sample configuration file to convert music cds to
# Ogg Vorbis using abcde version 2.3.99.6
