Ubuntu Multimedia :: Low Performance Playing HD Content?
Dec 6, 2010
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.
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).
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)?
I am trying to play embedded mp3 content in FF. When I click on the link to play the mp3, a new tab opens up and all I get is a grey screen. Does anybody out there have any ideas on this? I have run Autoten and installed all of the necessary codecs.
I'm currently running Windows 7 but I would like to switch to Ubuntu. I would like to know if I will see any performance drops while playing games under linux through Wine. I play cod2 and cod4 and I achieve 125 fps constantly, will I see this drop under Ubuntu through wine?
I am using find to search for .tgz files modified more than 7 days ago and delete them.find /directory/ -iname backup*.tgz -daystart -mtime +7 -exec rm -rf {} My problem is that find will go through the content of tarball as well and list all content. I want to only search main tarball and delete it if older than 7 days.
So this guy brought a CD full of crap (audio, picture, documents) and wanted to view the content. Ubuntu mounted it but said it was a blank CD. I think Ubuntu has some problems handling CD with mixed contents based on googling, I found some several years old bug reports and threads, but they either get closed without answers or just died because no one cares to respond.
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.
If you have the value 100 in File1 and the value 5 in File2, how do you write a script to divide the 100 in File1 by the 5 in File2 in Linux Bash Shell?The operating system I am using is Ubuntu 10 and object is to write a script to accomplish this task.
i have a desktop (lucid) which is connect to my home theatre system and advanced sound system and working without any issue.
now i got a laptop (lucid) which i usually use to watch streaming contents (videos and all) and play music (local and internet radio). i like to stream all of my audio (not video) to the deskop so i can use my home theatre speaker for the purpose.
I try to watch flash content but everything is covered with a pink layer... (see attachment file). I am using firefox 3.6.1.5 (same prob with opera!) and flash 1.0.2.r152 in ubuntu 10.10 with compiz disabled and GPU Override set to true (no difference with false..) I tried FlashAID for a clean setup and I have only flashplugin-installer on my laptop (no gnash or libswf...), I also tried it with the package "adobe-flashplugin" same problem. This and the a2dp-skips are my last problems before a perfect setup.
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.
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.

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
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?
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?
I know that this has probably been around these forms, but still. I recently stumbled upon one .mkv file and I wasn't able to play it in Ubuntu. I'm still not able. Looking at the forums around I see that many folks are able to play .mkv files with ease just running VLC player. So I'm quite confused that I'm not able to. So far I haven't had any problems with neither audio, nor video files in Ubuntu. Anyway, here's what I use: VLC version 1.0.2
(I saw that some folks have been compiling VLC, incluiding specifically the .mkv support, but that was two years ago. Now VLC should support it out of the box...)
And I should have .mkv support in the version of VLC that I have:
$ vlc --list | grep Matroska VLC media player 1.0.2 Goldeneye mkv Matroska-Stream-Demuxer
When I try to open the .mkv vile in VLC nothing happens. No errors, nothing. And off course neither video, nor audio.
I got a virus through thunderbird and had problems even after I removed it. Thus started over. Used CD to reload windows and then reloaded ubuntu using a CD. In ubuntu can not read CD. It doesn't show on desktop. Is there a program to download?
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?

So I don't use gnome, KDE, or XFCE, but I'm running Xubuntu. I'm constantly playing music via nvlc. While that music's still playing, I'd like to be able to hear a sound I run from the command line via
Code: cvlc beep.mp3
I've tried on and off over the years messing with pulse, esd, etc. output options for vlc, but never figured out exactly how to do this. In Windows, having a batchfile play a .wav at the same time as an mp3 player is playing music "just works" I know there must be a "just works" solution for Linux.
I bought an LG external cd/dvd unit (model: GP08 ). The problem is that I have no sound when playing DVDs. Everything else works fine. I installed libdvdcss (followed this link: https://help.ubuntu.com/community/Re...ts/PlayingDVDs) but still no sound on DVDs (the DVD works fine on a windows machine). I have an Acer Aspire One with Karmic Koala.
My newly installed (but not new) DVD drive seems to play some movies some days, but others all the time. I'm pretty sure it's just a little picky about scratches. I can hear it in the drive; when I insert the disk, I can tell when it isn't spinning. When it does start spinning, that's when the Media options window pops up asking me what I want to do with the disk.
I am new to this forum and ubuntu linux. I am having one .avi captured file in winxp using webcam. It is not playing in winxp 32bit. I googled and found more then 2GB file will not play in 32bit OS, so I installed 64bit Ubuntu desktop and trying to play with VLC but still it is not playing.
Using Kubuntu 11.04, I have all of my movies and music on a NAS, everytime I wish to play something (I have a computer hooked up to my tv this is how I play all media) KDE decides it needs to copy it to a tmp file first, I was unable to find a setting to turn this off and allow the file to simply play straight from the network drive as it did in M$ Windblows probably a dumb question.
I can't get my sisters Ubuntu to play some movies off DVD. I google searched for how to play dvds on ubuntu, and a site says basically "just install Totem" and the dvdlib3 (it already has dvdlib4 installed) so I went ahead and installed totem.I launched totem, but there is no option for opening a DVD, there's only Open File. which would mean I'd have to open the vob files, which are very confusing to navigate.
I tried VLC and VLC couldn't run it, so I tried VLC(Windows32 under Wine) and although it worked in the past, it couldn't read the movie either(the movie is Casino Royale and I watched it just fine on my Windows machineis there an easy method to just install some proprietary software that can play movies with a single click? like with the package manager perhaps? I couldn't figure anything out. It seems like Ubuntu should come pre-ready for DVDs and I don't understand why it isn't.
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.

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...
