Ubuntu :: Video Quality Is So Slow - Freezes Up?
Jun 15, 2010
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 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?

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.

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 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.

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 a vp6 codec flv. I have a wav file that I want to convert into mp3 and added to the vp6 flv. So when I play the flv the audio is added and the video quality is not changed.I tried:ffmpeg -i 20.flv -i 20.wav -vcodec copy -acodec libmp3lame new_file.flvbut I an error "Could not write header for output file #0 (incorrect codec parameters ?)". I'm guessing because it is a vp6 flv codec.Is there a way to just add an audio file to the flv? There is no audio in the current flv. I cannot lose any quality in the video.

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 installed fedora 14 on Dell laptop but I am unable to change resolution on my laptop also video quality is poor , I think proper drivers are not installed. I am new to Fedora, so probably missing something.

I am looking for a good alternative to Skype. I would like to have video and voice calls with a family member who uses MS XP but would like to avoid Skype if possible. Does anyone know of a good client with good video and voice quality that will work on both platforms. I'd like it to use open standards so at least we can use different OS specific clients if one is not available for both platforms. Googling hasn't yielded much and some of the results refer to really old (~2006) articles or apps. I hope I'm not doomed to using Skype. I've resisted so long with using SIP clients for voice but am stumped now that I want to include video.

OpenSUSE 11.1, 64 bit, 2 cores, intel graphics, 4 GB of RAM:_no_ problems
OpenSUSE 11.4, 64 bit, 4 cores, nvidia graphics, 16 GB of RAM:
Problem is very similar to: Problems playing mkv HD films in opensuse but not windows but with enough differences that I start a new thread:
* playback in VLC does not work -- there is only sound
* playback in SMplayer works, however -- when I scroll forward, the video freezes and sound continues, to unfreeze video I have scroll a tiny bit backward
I tried changing the video ouput driver (in SMplayer) from xv to xv/noveu-nvidia, it didn't help. Please note, that I use the same settings (initially) as before in OS11.1.

I installed Debian recently, and everything seems to be working fine, except some video games are unusually slow compared to what they would normally be. Tremulous, for example, worked reasonably fine on this computer with Windows XP, but now (Debian) for some reason it's laggy even on the title screen.
Something wrong with my video drivers?
All of the information I know:
The computer is a Dell Dimension 3000
RAM: 256mb? Gnome System Monitor says 247.1mb, SWAP: about 730mb
Processor: Intel Celeron 2.40GHz
HD: 25gb out of a 40gb HD free, and an external 1tb HD with about 920gb free
Debian Release 6.0 (squeeze)
Kernel Linux 2.6.32-5-686
GNOME 2.30.2 (I've tried LXDE also, no noticeable change)
Only linux on the machine.
glxinfo told me this:
Code:
64 GLX Visuals
128 GLXFBConfigs:
lspci told me this:

My Nvidia card broke down recently, I replaced it with Ati Radeon 2600HD Pro.
Now I have no compositing, everything freezes or it's just dead slow.
As for now I'm using fglrx drivers, but I've tried xorg drivers before, without success either.

So i just finally installed Debian Jessie OS, replacing Ubuntu. But now it is running extremely slow. It's not internet connection. The internet speed is running fine (Videos load quickly), but it's like the system freezes every 30 seconds or so. A video can be fully loaded but still stops and starts constantly. Just browsing the internet, or non-internet things do the same also. I switched back to Ubuntu to see if it was different on there, but Ubuntu is running fine.

I'm really new to opensuse, and linux in general. I started using 11.2 in may and I'm still having trouble. I started it on a newly refurbished HP Pavillion. It's always seemed to run slow, freezes up when I plug in my external hard drive, won't play music on amarok or it will lag, things like that. When I run it in windows everything works fine. and it has always ran really hot and loud when in opensuse.
To make things worse, lately if I open mozilla, all the programs/windows I have open will disappear, all my tabs will disappear, all the icons on my desktop disappear and my application launcher, clock, etc, all disappear. when i manually shut it down and restart it works fine for a while. I keep trying to find things online but I've got to the point where I'm afraid to mess it up more.

I am having a problem with my Fedora11, I am not sure wether it is software or hardware but this looks serious. My computer is running very slow and freezes up every few seconds. Every time I reboot I would get a kernel failure pop-up.
This is what the message says:
Kernel failure message 1:
Kernel failure message 2:

Whenever I'm playing a video in Totem, if I use the navigation bar thing to go to a different time in the video, the video output freezes. Audio continues, but video stops. If I pause the video first, then use the navigation thing, then click play again, it works fine. Same happens for music; the visualizer freezes if I drag the navigation thing.
Edit: If I put it on repeat, when the video or music repeats the video output freezes also.

I don't know what happened, but sometime within the last week I have started having a really annoying issue. Whenever I open a web page, that contains embedded Flash, in any browser (Firefox, Google Chrome, Chromium, or Opera), the entire browser, and all windows and tabs, freezes for about :15 seconds or so. After that time, everything unfreezes and works as normal, except for the video which often times doesn't even play after the freeze occurs. I don't believe I have made any major changes to my system, just the updates that show up in the notification area.

I have a Asus UX30 with an Intel GMA 4500MHD laptop with ubuntu, working with no problems except that when I'm watching some video it often freezes. The screen turns black and the only way to get it some where is to shutdown in the power button. Is there any special reason for computer suddenly freezes

I had been happily on Jaunty Jackalope until they stopped supporting it so I took the forced upgrade and it's HORRIBLE!
I feel like I'm back in Windows land. Within an hour of my first load I had my very first Ubuntu total-lockup. Just like Windows. In the 18 months I'd been using Jackalope I had not had a single crash. Not one.
It's slow, jerky, and has odd freezes. Just like Windows. Applications randomly stop working and die. Just like Windows.
Is there any way to fall back to Jackalope or is there any hope of them fixing Koala? 'Cause this is wretched.
I see there's another version out there...10.04.01.LTS. I'll try that. It can't be much worse.

My problem is this: the video that I receive during a video call will freeze after about 30 to 60 seconds. Before that, it works fine. And the outgoing video (that which I send to the contact on the other end of the call) is fine throughout.
If my contact resets their video by turning it off and then on again during the call, it will usually work again for a few seconds. Then, as always, it freezes.
So, I am clearly receiving the signal. But maybe I am overloading something? Is this a graphics card problem?
SPECS:
* Mobile Intel 915GM Express card
* IBM Lenovo X41 laptop
* Intel Centrino processor
* Ubuntu 9.10 (Karmic)
* Skype 2.1.0.47(Beta)

I decided to take the plunge and I totally replaced windows XP Pro w/ Karmic. I'm working on getting theatre mode set up as well as syncing my iphone.
for this problem I've set up dual desktop mode(both with the guide I found for Nvidia, and with ATI Catalyst control center) through the guide, the computer would freeze randomly and with CCC it seems to freeze when I start a video on the TV display.
I'm running a P4 3.2Ghz, 4G DDR2, ATI 256mb card w/ HDMI out
UPDATE: By changing the screen effects to none the computer doesn't freeze anymore

i've noticed a problem this morning when watching bbc flash videos on firefox (3.6). whilst the video is playing, firefox is fine and new tabs can be opened. but once you close the tab or window where the video was, firefox freezes and has to force quit. other flash video sites like videos, cnn, sky news, guardian and flash games seem okay and firefox doesn't freeze. bbc videos seem okay on firefox on winxp too. the bbc problem occurs on news video and on iplayer vids.

After going back to Windows 7, I attempted linux again, but this time I was greeted with some nasty bugs. And I have tried reinstalling multiple times, I can't find whats causing this. Video performance is choppy and just terrible. DVD's keep dropping almost 60% of their frames. Ubuntu Software Center keeps freezing near the end of an install (though does seem to actually finish), and then maxes out CPU and causes my laptop to heat up a lot..
Ubuntu 10.10 64-bit
AMD Athlon II 2GHz Dual Core
4GB RAM
ATI Radeon (I don't know off hand which model)
I have tried open source drivers and FGLRX (which holy crap ATI fixed the tearing I see!), but nothing fixes it. Other distros are not having these issues.
