Ubuntu Multimedia :: How To Enhance MP4 Performance
Jul 27, 2011
I've installed an older Intel/Compaq Evo machine with a single core 2.0 Ghz. processor and 2 GB of DDR ram in our livingroom, for movie viewing purposes. I'm intentionally using Xubuntu 11.04 without 3D to keep the used resources down to a minimum. There are no 3D games on this machine either since I'm using it strictly for watching movies on our TV. The graphic card is integrated with the 845 chipset/mainboard. It does receive up to 64 MB of Ram though which is drawn directly from the onboard 2 GB DDR. The following links provided me some linux related info. about this chip but I honestly have no idea how to use that since the intellinux site is set up horribly (IMO).
[URL]So with a 2 Ghz. processor, low resources, 2 GB of DDR, of which 64 MB is dedicated to the graphic chip, I figured that playing movies wouldn't be a problem .. and it's almost not. I can play wmf, avi, mp3, and other codecs without any problem at all. Even BlueRay works fine as long as they're AVIs. But as soon as I try to play an MP4 movie the experience gets very unpleasant. No crashes, just endless stuttering and sometimes lack of audio. Is there perhaps some way that I can improve that performance permanently without buying another graphic card? The machine is an ultra slim form factor so I can't even add a narrow format card to it.I'm stuck with the embedded 64 MB chip but I'm hoping that someone here can help me to get the most out of it

Still on lucid, I am trying to configure a decent console based boot process. I had to figure out some startup script errors and was upset what I had to fix just to see all messages properly. For me, having a 'talking' OS in favour of a Colourful-but-Black-Box-Liar without even one single record of a good logging policy is just one, but big plus of running Linux - please stop to windooze Linux
What I want:
- add 'text' to the kernel parameters (fixed or grub editor)
- have all messages issued during the boot process on the console

we want to enhance the current libpcap version 1.1.x to provide timestamp in nanosecond resolution.
While searching related to same, we found that enhanced libpcap requires x64 architecture.
Is that so?
Do we need 64-bit architecture for using enhanced libpcap for nanosecond timestamping ?

I'm looking for an easy to use video editing tool for cleaning up and enhancing the simple movies that can be made with digital compact stills cameras. My camera (a Panasonic Lumix) records these as Apple Quicktime MOV format and uses a very basic internal microphone to enable it to include a very poor soundtrack. My current desktop is Ubuntu 10.04 running on an old Athlon 64 single core with 2GB RAM with "enough" spare disk capacity for these very short home movie clips. I can play them back with the standard media player at present. I'm not a professional multimedia artist and I'm looking for a very simple, easy to use tool that will enable me to clean up, convert, etc. Ideally, I'd want to send these either via e-mail or on CD to family and friends.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

I have a custom built PC with a AMD 9650 2.3ghz quad core, 4gig of ram, nvidia geforce 9500gt graphics card. With windows 7 my movies look immaculate but I want that from Linux. My first problem consists of lines in my players. To test out the performance I am playing Final Fantasy 7: Advent Children Complete Blu-Ray. The video file has been ripped and placed on the HD. MPlayer has lines everywhere, VLC is very good but line every once in a while, XBMC plays bout as well as VLC. The first part that confused me was how MPlayer was worse off. I have followed all the stickies and this is a fresh install of ubuntu 9.10. The Second problem I am having is getting my onboard audio to work. My board comes with 8 channel audio support but my 2 side/back speakers wont work. I have messed with the application settings and the actual settings in Sound Preferences.
Here is a link to my board specs

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 dell vostro v13. I am have installed LMMS which runs ok if I put minimal demands on it but if I start putting to many demands on it like running More then three Zynaddsubfx plugins or multiple sample players the cpu moniter goes into the red and it starts to sound bad and slow down a great deal. I know a small laptop is probably not the best choice to run a DAW on unless it has a good processor but this is the only computer I currently have and I really like LMMS. Is there any way I can get more performance out of my computer? I looked a little into overclocking but dell Bios Does not allow for this. Is there any tricks that I can do to get LMMS to perform better given the limitations of my system?

my friend has a dell inspiron 4600 desktop that we recently install ubuntu on to replace windows xp on. now when we try to play some hd videos in vlc player it's pretty low frame rate but i'm not sure why. if we play 720p on videos it's pretty low frame rate too. in windows xp he could play these videos flawlessly. we tried installing a nvidia driver but it stops the desktop from working. in 10.04 the driver installed fine, however, in 10.10 after installing the driver on next boot it would start up at just a terminal. not a terminal window but just a black screen with white text on the entire monitor. i could only fix it by editing the xorg.conf changing a field that said "device: nvidia" to "device: nv". that driver may also be causing a problem.
if i cannot find a solution we will reinstall windows xp which i rather not do because i think ubuntu runs better. also, we installed xubuntu-desktop package so we are running xfce instead of gnome.

Is there anything I can do in Ubuntu 11.04 to get the Intel 945GM to work more stable and run faster? It won't load the Unity interface at ALL. It won't load the Classic Desktop unless I use the one without effects, or else the title bars disappear. Is there something I can do to make it more stable, and run more efficiently?

Is there anything that can be done to increase video streaming performance?The general impression I got is that it's mainly an adobe problem and not much can be done, though currently streaming is nearly unwatchable. When I switch from full screen to normal size many of the players freeze, ..... HD is unwatchable etc.

Does anyone know of a program that can create effects like reverb/echo during a live performance? I like Audacity, but it seems you can only do this kind of stuff to audio that has already been recorded, not while you are performing it live.

I posted a few weeks ago about Flash performance in Firefox vs. Google Chrome. Thanks to all those who responded. I finally figured out the problem in Firefox, it was Compiz desktop effects. With effects off, flash in Firefox is just as fast as Google Chrome. I am not sure why Compiz only affects Firefox Flash, but apparently Chrome is not affected. I know there are a lot of posts about this topic, so before driving yourself nuts installing FlashAid, and running terminal commands, try disabling desktop effects first.

Using either MPlayer or mplayer2 under the video player SMplayer, when clicking on any drop-down menus, the video will freeze and then skip. Once the drop-down menu animation has completed, the video playback will play normally. This happens when using VDPAU to play back H.264 MKV files. Audio playback of the video is never interrupted. why VDPAU will not play nice with SMplayer & Compiz?
System Info:
AMD BE-2400
1GB System Memory
Natty Narwhal 11.04
Ubuntu Classic with Effects
Nvidia 9500GT
Video Driver 270.41.06-0ubuntu1

My problem is that my computer plays MTS videos very bad (the videos get freeze, etc) in Ubuntu 11.04. I tested many players, but I didn't get good performance during the playback in any of them.
However, in the same computer, I use K-Lite Codec Pack in Windows XP and MTS videos are fine!
Is there any way to play MTS videos in Ubuntu very well?
Performance is excellent in both operating systems (XP and Ubuntu 11.04).

So for the last, oh, three or four hours now, I've been trying to get videos to play properly in Ubuntu. I have the default player, I have vlc, I (apparently) installed mplayer, but it won't play anything at all.
I was having horrible screen tearing with standard definition .avi's in vlc, fixed that by setting vsync in catalyst control center to always on or whatever it is.
Now, I have tried to run a 720p x264 video. It PLAYS, but not well. Audio is fine, however video is all jerky in VLC, and in Totem it's just a mess of screen tearing (although the video does no jerk on that player).
I have just spent HOURS trying to get VIDEOS TO PLAY. This makes no sense. Playing a video should be the simplest thing in the world for any OS to do, but with Ubuntu it is like pulling teeth. I have NEVER been so frustrated while using a computer. What is going on here?
BTW, I installed every single thing needed to use mplayer but it still does not work. The player comes up but will not play any type of file.
My system specs:
2.2Ghz dual core (intel)
3gb ram
1GB radeon hd 4650 vid card
asus ipibl-lb mobo
I was really enjoying Ubuntu until I got around to trying to watch some videos. Now I am maybe minutes away from going back to vista. At least on there I can watch full 1080p videos if I want with no problems.

I am running kubuntu 9.10 on a dell inspiron 14 with an intel GM45 graphics card. When I run 3d games like Nexuiz, openarena and tremulous I get really random performance. Sometimes things are totally playable with somewhere between 50-80 fps and other times I get maybe 4 fps and everything takes forever to load. These effects persists between logouts, X restarts and reboots! I get no errors when I run things in console either.I never really play games much but when something doesn't work...

I'm using Lucid and there is a noticeable drop in performance when using flash under Ubuntu. Video playback appears to be much more choppy than in windows. The driver I'm using according to an xorg config file I made was just "intel." Are there any options I can configure to get it to run more smoothly? The computer itself is a laptop - Toshiba Satellite m45-s331. I tried using gnash and others but they are even worse than the Adobe flash.

i have an ati radeon x1550 (pretty old, i know) graphics card which worked perfectly under windows 7. i recently read that ati appears to have dropped support for this card installed on recent ubuntu distributions (i'm using ubuntu 10.10 + kde 4.6.1) the thing is, when i'm watching something on videos or playing a movie through vlc, the image looks jittery (random horizontal lines that break the image, it's pretty subtle but it's there...) i'm new to ubuntu (switched from windows 7 a couple of months ago) and what i'm looking for is one of two:
-either a solution to my drivers problem so i can use this card with full 2d and 3d support (like i used to in windows) or, a recommendation of which graphic card i should switch to (my motherboard has a 'pci express x16' slot). i've searched countless forums and sites but i can't reach a final conclusion: am i supposed to have good 2d and 3d acceleration with this card (with the right drivers installed)?
if the answer is 'no', then i'd like to know what i should buy. for what i've read, apparently i should stay away from ati and intel and look for nvidia. i'm not a gamer so i really don't need an incredible 3d acceleration (although some would be nice, just in case) what i really need is for my system to be snappy (i work with my computer) and most of all good support for multimedia apps (i would like to be able to use xbmc smoothly for instance) i'd like to know which is the cheapest graphics card that i can get that will meet my needs (the ones i just listed above)

Is there any way of improving performance with the GTX 470 using Wine software with Debian Squeeze?
Installed version of Wine is 1.3.6 tested with different versions of nVidia drivers including the latest one, still VERY slow performance and many quality settings are in red. Setting WoW to use OpenGL improved the performance, but deactivated many quality settings in red, unfortunately. Looks to me as it's using lower features than OpenGL 2.0?? So what's up with that? GTX 470 supports OpenGL 4.1 so I suspect it's an limitation in Wine software, can anyone confirm this?
Default kernel 2.6.32 is used in all of this. The computer is an Intel Quad at 2.4ghz + 4 GB DDR 2 or DDR 3 memory.

I am preparing to purchase a new laptop, with Ubuntu 10.04 built in, from System76 with 8.0 GB DDR3 1333 MHz RAM, ATI 4570 graphics with 512 MB GDDR2 memory, 500 GB 7200 RPM SATA II hard drive, and I get to choose a CPU. I am wondering: 1) Would I get better 1080p video playback performance with a dual core Core i7-620M or quad core Core i7-840QM CPU? 2) What is the best playback software in Ubuntu that takes full advantage of such a CPU, and also the GPU?

having not experienced the issues with jaunty and intel display cards, i can't say whether this is a real problem or not. from what i can tell, mtrr is not a problem.
on my new dell mini 10v w/ intel 945gme and a fresh install of karmic unr, video playback performance is only so-so.
most videos-style flash video is decent. local h.264 playback from .m4v and .mov containers is flawless. but streaming flash video originating as h.264 is dismally choppy - this includes vimeo and hulu-quality streaming video.

I have noticed that, using nvidia's latest drivers, HDMi output to my 32" LCD (1920x1080) and totem or vlc, the video on my LCD gets a bit "choppy" when the image changes faster.. some bars start appearing on the moving parts of the image.. like the system is having trouble rendering the video. This doesn't happen on my laptop screen even when both displays are running at the same time.
Also, this problem doesn't appear in windows 7, everything works perfectly there with one odd thing... the picture gets "choppy" on the laptop screen when I'm running both at the same time. It's not that noticeable, but I can tell the difference between windows and ubuntu in quality and it's annoying me

I'm considering getting a new motherboard in the future that has a pci-e x16 slot, but the slot only runs at x4 bandwidth.I will be using a 8800GT, so my question is will the x4 bandwidth have any detrimental performance hit when playing HD videos using VDPAU (H.264 codec)?

Why does flash perform so badly in fullscreen mode but not when out of it? [URL]... that is a 1080p flash video that runs completely smoothly for me when not in fullscreen mode, but after entering it the frame rate drops significantly. Am I the only one affected by this? Is there a way to fix this?
My computer is 64 bit and is running flash 10.42
