Ubuntu Multimedia :: 1080p Playback Performance In I7-620M Versus I7-840QM
Aug 31, 2010
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?

I have a high resolution file (1080p) encoded with H.264 and when I play it back, it lags at certain parts (and enough parts to destroy the job of watching the video).
I don't think that my computer is that crappy and it has been able to play many H.264 encoded files with high resolution - so there is always a possibility that this file is just encoded poorly (lacking a better computer, I cannot test).
For information, I'm running Ubuntu 9.10 64 bit. I have a Intel Core2 Quad CPU Q9550 (@2.83 GHz). I have 8 GB of RAM (forgot the speed off the top of my head). And a Nvidia GeForce GTX 280 (1 GB of memory).
During the playback, the RAM is far from being completely used; however, it seems that one (and only one) of the cores of my CPU becomes saturated at 100% precisely at the moments in which the file lags. When the CPU utilization is below 100%, there is smooth playback.
My question is - is it possible to use all four cores during playback, or is such a process not capable of easy parallel processing.
Another side question is, how can I be sure that my GPU is being used in the decoding process - or is that also being under-utilized?

I have a Zotac IONITX-F-E motherboard (Intel Atom Dual Core 1.6 GHz + Nvidia ION) -based box with Ubuntu 10.04 64-bit installed. Do you or does someone you know have the same setup as I do? If so, do they have 1080p video playback working? If so, what driver are they using? I've tried following every guide I could find, but no luck so far. I have libvdpau1 and libvdpau-dev installed. I have the nvidia 195.36.24 driver installed (I used the nvidia installer). I have mplayer installed (which I compiled from source with --enable-vdpau).
I try to run mplayer with this command:
Code:
mplayer -vo vdpau -vc ffh264vdpau path/to/myfile.mkv
I get the following message in my terminal:
Code:
Error opening/initializing the selected video_out (-vo) device.
I have libvdpau-dev and libvdpau1 installed.
After Googling this problem, I found a post that suggested the following steps:
Code:
sudo add-apt-repository ppa:nvidia-vdpau
sudo apt-get update
sudo apt-get install nvidia-glx-195 nvidia-195-modaliases
It turns out that I had already added the nvidia-vdpau repository. However, despite that, I get:
Code:
E: Couldn't find package nvidia-glx-195
The same problem exists for the nvidia-195-modaliases package. Do these packages exist? Is there some other way to get them?

There are 3 channel DDR-3 RAM kits available on market.Would its performance be better than dual channel RAM kit, apart from RAM capacity? I'm planning to build a new box testing server consolidation on virtualizaion running Xen/Vserver/OpenVZ as software. All servers running 64bit Linux OS. My new planning is to get 2 sets DDR-3 1333/1600 4Gx2 kit. I may consider 3 channel kit dropping the total RAM capacity to 6G if it has better performance. Besides can mobo support dual channel RAM also allowing 3 channel RAM to work on it without sacrifying performance?

Im confused about buying nVidia 9800 GT or ATI HD 4770, In the 1st place I am going to buy this card to play HD videos 720p & 1080i and in the 2nd place to play games.I was using nVidia 6200 LE which doesnt support VDPAU, So nVidia use VDPAU in the newer cards to play movies, my question is:* Does ATI have something like VDPAU that have the same video playback performance ?

I ended up getting 1080p playback working perfectly with vlc on my 1201n about 2 months ago, but then I decided I'd reformat my system to clean it out a little. There's other tutorials out there, but none are as straightforward as that one. I literally copy and pasted the commands and it worked like magic...now I have the latest nvidia driver installed, but vlc 1.1 won't let me check the GPU acceleration box under Preferences > 'Input and Codecs'.
I remember that this tutorial gave you PPAs for debs of vlc pre-1.1 git files, and a list of all the necessary software to install (vlc, vdpau, smplayer). It was hosted on a site other than ubuntuforums, and it was the only one that worked at the time for me.
Anyone know what I'm talking about, or give similar links? I think with this new nvidia driver stuff is actually being slowed down a bit, but that doesn't explain why VLC won't let me activate GPU acceleration.

I use Ubuntu 10.04. I need to play a full HD (1080p) video on my pc:
CPU: AMD Athlon X2 7750 BE
MB: ASUS M3A32-MVP
RAM: 2x1GB KINGSTON 1066MHz
VGA: ASUS 8800GS
I think my PC should be able to play it, but the video is really not fluent. What should be wrong? Power less hardware? Wrong codecs?

This forum has been a wonderful treasure of knowledge. I am stuck up with something thats getting onto my nerves. I have installed lucid and followed the perfect desktop guide.
I have a mkv file (4.6Gigs) 1080p HD with DTS 5.1 audio. when I play the file either of the video or audio gets stuck (mostly video) I tried every possible configs from this forum but in vain. Im using Dell LAT D830 with 2GB RAM 2.2GHz CPU NVIDIA Graphics.

I'm having trouble getting 1080p out my xfx 9800gt that has an onboard hdmi socket. No doubt my HDTV is 1080p (panasonic TH-427PZ70B a few years old now), and it will do and has run at 1080p 60hz.
It auto detects the display as simply panasonic-tv and outputs at 1080i. As I've been running mythtv with tv tuners this actually worked quite well as dvb-t is interlaced anyway and most ofthe HD video files I play are 720p. However I would like to run it at 1080p for all the usual reasons- especially as I have some 1080p files I'd like to enjoy in all their glory!!
This doesn't seem to be ubuntu specific as mandriva behaves the same, and makes no difference if I use the open source (default with 9.10), the official nvidia package or as I've just tried 10.04 with default and nvidia.
I've searched around for nvidia hdmi 1080p etc but can't seem to dig up anything useful. Surely I should be able to force the graphics card to output standard 1080p 60hz?
Should I be able to do this through xrandr by setting a modeline or in xorg.conf or nvidia control pannel!?

I had a problem playing full HD videos (1080p @ 30 fps), frames dropped, CPU utilisation (on 1 of 2 CPUs) maxed out etc.As I'm still stuck on Hardy I didn't find much stuff that directly answers my question on how to play this... After hunting about a bit the following two links gave me some idea of what needs to be done, namely install a new version of Mplayer that supports VDPAU (NVidia's hardware video acceleration solution).
[URL]
Luckily I had a NVidia video card that supports VDPAU and I had installed the NVidia proprietary drivers before [URL]To check if your NVidia card supports VDPAU please look at the proprietary driver release details.
Quote from Wikipedia:
"Currently only second generation of PureVideo HD bit-stream processor in some of NVIDIA's GeForce 8 series and later graphics cards hardware that has support since the Beta device driver version 180.06.[4] Unsupported hardware from the GeForce 8 series includes the 8800GTS 320/640MB editions and the 8800GTX. Later cards based on the G9x series cores e.g. the 8400GS and the 8800GTS 512mb (G92 core) are supported."
I usually play using VLC but was put-off from trying to upgrade that to CDPAU support because of this little detail from the Ubuntu forum links above:
Quote:
"VLC is available with vdpau by way of VA-API, in this PPA:[URL]However, to install it you'll have to upgrade your precious and very touchy ffmpeg packages. There have been a couple of SONAME upgrades since Karmic's ffmpeg was released, and this will inevitably result in breakage of anything that A) uses dynamic ffmpeg, and B) is not rebuilt against the new version, ie. every package that's on your system that didn't come from that PPA."

I've tried watching material in 1080p resolution on my notebook and i experienced some slowdowns, tearing, etc. Video is encoded by x264 and sound is flac 5.1, all in mkv container. I know it's quite heavy one, but it was playing quite good on windows+CoreAVC, so i expect no less from my shiny Ubuntu I did a bit of googling and found out that AVIVO/UVD/Whatever is already turned on by default in fglrx drivers when using Xv, yet CPU is struggling on 90-100% load. Is there a way to turn hardware decoding on? It doesn't seem to work by "default" (or i'm too desperate to acknowledge that hardware acc is already on and still struggling to decode this ).
Specs of my notebook:
Intel Pentium Dual-Core T4200 2.0 GHz
Mobility Radeon HD4570 256MB with fglrx from maverick repo
3GB RAM (doh!)
mplayer and codecs from medibuntu repo
mplayer uses -vo xv -va pulse , ffh264 and ffflac codecs

Are there big disadvantages to building a computer around a motherboard with ATI Radeon graphics instead of Nvidia? I am using an AMD CPU to save money, but all the motherboards AMD recommends use ATI. I have always used Nvidia in the past, And am not sure what the current state of ATI Linux drivers is. I know I would be giving up VDPAU acceleration for video playback, but hopefully the Athlon� II X4 635 processor I am looking at has enough horsepower to handle this on it's own, even for high-def h264.

I am in the process of building a new computer as my current tower is ~6.5 years old; in the past few months, it has started to show it's inability to keep up with the times.One outstanding decision I have is the selection of video card. I use my Ubuntu desktop heavily for multimedia, so the first and foremost requirements for a video card are:Seamless Compiz support Seamless hardware video acceleration of MPEG-1/2/4, VC-1/WMV9, and H.264
I have a laptop with an Nvidia Quadro NVS140M, and while it only supports feature set A, I got it working with some (not all) H.264 videos, greatly reducing my CPU usage. This has led me to the conclusion that an Nvidia card will suit my Linux needs just fine.
Having said that, I will also be doing some gaming on this computer (under Windows), and so I will also require a high-performing 3D card. My current understanding is that AMD is ruling the roost in this regard with respect to bang/buck.is AMD's XvBA hardware video acceleration at a useable state, and if so, does it perform as well as Nvidia's offerings?

I have a question about audio recording. I've always wanted to set up a sort of personal studio. Not anything too professional, but I want to be able to make quality recordings without too many problems. All I'll probably end up using is a midi keyboard electric guitar and bass. But what I was wondering was, is it a better idea to get a Mac for something like that, or will Ubuntu support that just fine? I know there's great software available, and I've got used to using Jack. But I've read problems about real-time kernel support and xruns with Jack and Ardour, and I'm just wondering if that's something that will make using Ubuntu for this complicated.

I just upgraded from 9.10 to 10.04 by doing a reformat and fresh install from the cd. I have an old dell inspiron 1000 with a 2.26ghz centrino and SiS integrated video chipset.It used to run flash player playing 360p ..... clips in fullscreen very smoothly and better than my windows 7 install but with 10.04 it is doing about 1 frame every 5 sec.

I am using debian squeeze and did an aptitude upgrade yesterday. Today I've found that VLC won't play any video; the files open and the audio plays, but the video is black. The aptitude log is below.
I note that VLC received a security upgrade a few days ago, but my suspicion is that the source of this problem is more likely to be the upgrade of libavcodec52 from version 4:0.5.2.6 -> 5:0.6.1+svn20101128-0.2. I believe this upgrade came from the debian-multimedia stable repo I have enabled.
Does this sound right, and what could I do to fix my VLC playback? This is new territory for me, and I'm slightly surprised that such an upgrade would come from the stable branch of debian-multimedia (although I know this is not an official source).
[Code].....

craigevil wrote some years ago: You need to be root to edit your /ect/apt/sources.list
Try doing gksu gedit /etc/apt/sources.list in a terminal if your using gnome or kdesu kwrite /etc/apt.sources.list if your running kde.
Do not give up once you get the hang of things debian rocks.

I am running a java-based music player on two machines, one running 11.2 and the other running 11.3. I wrote the code myself, so I have complete control over it. Both machines have Sun java development kit installed, and both have version 1.6.0. The tracks of a given album are each played by a separate thread. Each thread requests the use of the audio device and plays through it. Under 11.2, the device is then locked for the use of this thread, and once the playing is through the lock on the device is automatically removed and the next thread starts playing its music without difficulty. I have no control over this lock, though. It appears to happen at the OS level, independently of my code.
When the exact same code is running under 11.3 the first thread plays through as before, but then the next thread does not manage to get hold of the audio device. It appears to play but no music is heard. When it finishes and the third thread tries to start, I get a "line unavailable" exception. difference between 11.2 and 11.3 in the locking mechanism of audio devices by an application? Is there anything programmatic I can do to remove the lock myself?

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.

Yesterday I fresh installed Ubuntu 10.04 64 bit LTS on my Toshiba Laptop. This is my second time with Ubuntu so bear with me. I got everything working even the webcam but it won't play dvd movies. When I go to the DVD player icon and try to open it...its won't because it doesn't recognize the dvd format.I have searched but only end up trying stuff that didn't work for it. I guess what it needs is Codec's.
