Ubuntu Multimedia :: What Affects Video More GPU Or CPU?
Jun 16, 2011
I have a laptop with Ubuntu 11.04 on it. It has a built in graphics processor. I am not sure of the specs on it, but I was able to run DVDs easily on it when I had Windows XP as the OS. I am now trying to load and edit video, but am having difficulties. My questions about that are in another thread. My question here is this: What affects video on a computer more, the GPU or the CPU? I have received advice pertaining to the video card, but was under the impression that the CPU had more to do with the computers ability to handle video, especially getting into the hi-def range. I recently rebuilt my desktop with a much newer processor, but with the same PCI Express video card. My old rig could not handle even 720p, but the AMD dual core I installed can play 1080p no problem. Different CPU same video card.

I recently reinstalled Ubuntu 10.10 in virtual box 3.2.8 on Windows 7. I did a clean install, did the major updates, checked for updates after via the terminal and then installed the guest add-ons, re-booted and nothing, it keeps telling me it cant enable desktop affects.

Several days ago I posted a query about the effects of upgrading from 8.10 to 9.04 in regards to Thunderbird/Firefox emails and settings. I wondered if I would lose all of my emails, addresses, bookmarks if I make this upgrade. So far there have been no responses. Maybe it is such a dumb question that no one cares to take the time to respond. I understand that I can save addresses as ldif files and I can save bookmarks and re-import them, and I can save my profile (which should contain all of my old emails), but I've never gotten the profile thing to work properly.

There's some bug or other error in the updates I've just installed. I run Update Manager very frequently (almost daily). The last time I ran it was 2 days ago, so this bug can only have been released into updates today or yesterday. I ran it this evening and there were quite a lot of new updates (around 50mb in total), and I installed them all without really checking to see what they were - but as I'm new to Linux I don't exactly have any weird or rare software running on my laptop, so they only would have been for Ubuntu itself or some very common programs.
After installing it required a reboot. Upon booting up again, the volume icon has turned to 'Mute All' and I am unable to turn my laptop off. Telling it to shut down simply causes the screen to go black for a couple of seconds and then return to the login screen. I also notice that the Suspend/Hibernate options have disappeared, and I now only have the option to Log Out, Restart or Shut Down. {As I'm new to Linux I have no idea how best to proceed, or even how to officially 'report' this if indeed it is a bug contained in one of the updates.}

We just doubled the RAM on our RHEL 4 production servers...Oracle from 16gb to 32gb and Apache/JBoss from 8 to 32 gb. I am trying to figure out how to get the biggest bang from the increased RAM. Should kernel.shmmax be upped to be 50% of the 32gb....from its current 8gb? I need to create the largest possible SGA and was unable to do so, apparently because the kernel.shmmax value had gone unchanged.
And for the JBoss web servers, also RHEL 4, and particular kernel changes which can take advantage of the increased RAM and provide an immediate performance improvement?

I've been scouring the internet for an answer to this problem. I am using Squeeze and have properly configured Grub2 to set my console screen resolution to 1024x768x32 (as per updating /etc/default/grub to contain 'GRUB_GFXMODE=1024x768x32' and updating /etc/grub.d/00_header to contain 'set gfxpayload=keep') and everything works wonderfully. My resolution is set as it should be. However upon installing Xorg (aptitude install xorg ratpoison), my console resolution gets changed to what appears to be 1280x1024.
I thought that this was due to xrandr, however when I issue:
# xrandr -s 1024x768
only the X resolution is changed. When I then CTRL-ALT-F1 back to the console, the resolution is still at 1280x1024 (I am aware that xrandr only affects X, but I assumed that because my console resolution was correct before installing X there might have been some correlation).
I would like for my console resolution to stay at 1024x768 as per Grub2's configuration and for X's resolution to be at 1280x1024.
PS I also noticed that prior to installing Xorg, my CPU boots up without any screen blanking (only for a second or so). However, after installing Xorg, during the boot process the screen does blank briefly. It is at that time that the resolution gets changed to the 1280x1024 setting.

I just preupgraded from Fedora 14 to 15 on my Toshiba NB205 netbook (the preupgrade went smoothly by the way).
Immediately upon logging in, I discovered catastrophically poor quality of font rendering in every terminal window program I tried, (and I checked plenty like LilyTerm, Sakura, gnome-terminal, etc) and in web-browsers.
The symptoms are the same for all applications: the glyphs are very thin, anorectic, and very ugly.
The described behavior is desktop independent: same in Gnome (3 and the fallback mode), fluxbox, Openbox.

I want to watch a certain video on [url]...., but I get an error message instead. Some videos can be played, so I'm thinking it's a form of restriction, but I can't be sure.I tried using a few proxies, but on some the error message persists and on others the video doesn't load. I'm running Ubuntu 9.10 and Firefox 3.5.8.

When I play large HD videos in mplayer, the video and sound frequently get out of sync, and the video plays a little strangely (occasionally speeding up and occasionally slowing down).
I think it's because mplayer is only running on a single core. As I've got a quad-core processor, it seems inefficient. I've seen that there is theoretically a way to get mplayer to work with multicore setups, but it requires compiling with different options. That'd take me a little while to work through.
Ideally there would be a pre-compiled version in the software centre, or a player which has support built in (again, ideally in the software centre). Is there such a thing available?

I have a video file in which the audio runs faster than the video, so they quickly go out of sync. The way to fix it would be to separate the audio and video streams, speed up the video (the audio is FINE, it's the video that's wrong), and then recombining them. What is the easiest way for doing that?

video playback is like I have applied a blueish sepia filter over it. And this is just the playback from totem player or mplayer, and not the playback from ..... (and generally online streaming) - this works just fine. this messy video playback also appears when I use cheese to capture video with my webcam. Note that the preview picture of the video file on nautilus has the natural colours it should have.
at first when I installed the os this particular problem didn't exist, but it came up the time I decided to follow the "comprehensive multimedia guide". So now I have all the pros of following the guide, but this is a major con...

this happens with both VLC and Totem, when in either of those programs playing a video, if I click on one of the top menus, say View in Totem, the video stays on top of the drop down options. In order to see the options I have to hover over them with the mouse at which point they become momentarily visible. I read a post somewhere where someone had a similar problem and it was solved by reinstalling Compiz, but I've tried uninstalling it entirely, reinstalling it, etc. and none of it works. It doesn't happen with flash videos in firefox, it does happen with visualisations in Totem, and it only started happening since I upgraded to 11.04.

My system: Pentium 4 3.6 GHz, 3 Gb DDR ram, GeForce 210 video card, Ubuntu 10.04.
I have previously used Cinelerra-cv (on Karmic) and recently Openshot (on Lucid) with not much trouble. I have been sampling other video editors (Kdenlive, avidemux, kino etc). Now I have my video card crashing whichever I use, mainly when trying to load clips. I have disabled Compiz, uninstalled all video editors and then reinstalled one at a time. I still get early video crashes whichever I try.

I am setting up a MythTV environment to switch from Windows based MediaPortal (with a high number of disturbing bugs). Yet, I have three difficulties, which I want to discuss with you. They are:
- No audio via HDMI see [URL]
- Video resolution seems to change during video playback
- Channels cannot be found via DVB-S [URL]
As you can see, I have created three posts to keep discussions focused.
Alltogether I have the following setup:
- AMD 5050e CPU
- 8 GByte RAM
- Biostar TA890GXE
- Samsung LE40M86BD, connected via HDMI (and only HDMI)
- Mythbuntu 10.10 with proprietary drivers installed
- Technisat Skystar HD2 DVB-S card (two times)
Now, here is the problem:
Whenever I playback any video material using e.g. VLC, the screen resolution changes. This also applies when playback the video in a window and not fullscreen. The problem is that whenever the screen resolution changes, short time later the TV set blanks screen and show the TV set specific information "unsupported video mode".
How can I enforce to stay in the configured video mode?

Just installed Ubuntu 10.10 on an old Dell Dimension 8400 with an ATI RV370 Radeon X300 video card and 512MB of Ram. The video seems to go very fast and skips. I followed the Comprehensive Multimedia & Video Howto but still have the same issue. I have also read many posts but I have trouble understanding some of the responses. Could it be the low amount of RAM?

I have an integrated intel video and latest xserver-xorg-video-intel driver(using only stable repo). Now I wanna watch high-res video. From the bits of info collected from all over internet I understood that I need to:
1.aptitude install libdrm libva.
2.compile or find the .deb mplayer-vaapi and install it.
3.add -vo vaapi -va vaapi to the mplayer command line in gnome-mplayer.
My question : is that correct or did I miss something? Do I have to compile latest libdrm and libva or the ones from the squeeze repo will be good? Do I need kms enabled, i.e. install firmware-linux-nonfree?

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 been looking on Google to convert videos to mp3 audio and all I get is just a video conversion from one format to another and some things I installed just get error messages so I took them back off. Anyone know the proper syntax in Mencorder to convert a video just to audio? Or any other program I can use that won't cause this much trouble?

To get multimedia working, or explain what I'm doing wrong.
The problem is that none of the video players doesn't play video, they show only black window and play audio.
I have Fedora 11 Leonidas, fully up-to-date.
I have installed rpmfusion and livna repository.
I have installed following packages:
When I try to play video with totem, it doesn't output any error, but just doesn't play video.
with mplayer:
xine and kaffeine just say:
vlc:
I tried several different files, which works perfectly in windows and ubuntu.
I installed windows binary codecs for mplayer to /usr/lib/codec/

I played a 16:9 video from the laptop on my TV, connecting the TV with a video cable. My laptop has a 4:3 screen, and that's what I got on the TV: big black borders on the left and right of the 4:3 picture. I messed around with Display Settings, but I couldn't get a 16:9. Is there some way to get a 16:9 picture on the TV?

I've had performance issues in Chrome and Mozilla with flash streaming video for months and am trying anything to fix the problems.Today I wound up with no video at all. You tube videos are just a plain grey box now. Daily show is just plain black boxes where the videos are supposed to appear.
