Ubuntu Multimedia :: QuickTime Renderer Was The Only Rendering Container That Didn't Result In Sped-up/compressed Video Or Correct Rendering For Just Fifteen Seconds?

Mar 7, 2010

I downloaded an FLV video and placed an extra MP3 file over it. Two files. Total: 30 MBI experimented with about seven rendering containers, and QuickTime renderer was the only rendering container that didn't result in sped-up/compressed video or correct rendering for just fifteen seconds.How in the name of all that is holy did this rendering end up with 570 extra MB?

Ubuntu Multimedia :: "Nvidia: Direct Rendering Failed, Attempting Indirect Rendering"

Apr 3, 2010

I recently downloaded Frets On Fire and the HRP Polymer pack for Duke3D...Duke3D runs fine with just EDuke32 and no mods, just Duke3D and EDuke32. But when I try the HRP Polymer pack, it says in Terminal "NVIDIA: Direct Rendering failed, attempting indirect rendering." This is fine...if I want the game to lag like hell, I'm sure my video card and the driver for it support DR, the video card is a NVIDIA Geforce FX 5200, the same message appears in terminal when I run Frets On Fire, I think it does with other games too, if someone could explain how to enable Direct Rendering.

Software :: Cinelerra QuickTime Movie Rendering Error

Jun 1, 2009

I've after an agonizing process of editing I finally finished my video that I was working on. Now it's time to render it, I want to render it to quicktime for linux so that I can encode to mpeg using mencoder as described in the cinelerra docs. Problem is , the movie won't render, it shuts down the process saying render error and that's it.

The docs say that quicktime requires these properties:
Audio option Two Complements 16bits (PCM)
Video option DV
but can't find any place that asks for anything like that setting.

Ubuntu Multimedia :: CPU Doing All Video Rendering?

Oct 21, 2010

I am completely new to Ubuntu and so far am pretty happy. I am running into an issue playing web videos, ..... (flash) as well as html5. What is happening is that the CPU is doing all the work instead of the GPU causing the video to skip/stutter, here are the system specs.

MSI K7N2 Delta 2 LSR (latest bios)
AMD Athlon XP 3000+ (Barton)
2GB's PC3200
nVidia 6800GT (AGP)
Ubuntu 10.10 32bit (fresh Install
nVidia driver 260.19.06

When video is played the CPU's useage climbs to 100% and video lags. Again I am completely new to Ubuntu as well as Linux but I am trying, lol.

Ubuntu :: Compiz Rendering VLC Fullscreen Video - Cannot Control Playback?

Feb 28, 2011

I have Compiz Config Settings Manager installed on my Ubuntu 10.04 machine. All the effects are working properly and everything is running fine. However when i play video with VLC Media Player, i would only get audio and no video. After looking this up i changed the output to X11 vidoe Output. I started getting video and audio. But when i switch to fullscreen mode the fullscreen video window is rendered by Compiz and thus has all of those window effects like wobbly, minimize, maximize and stuff are also applied to the full screen video. It also does not have all those controls that vlc normally shows when you wiggle your mouse in full-screen mode. I tried disabling the Video Playback option from the CCSM window, but to no avail.

The same thing also happens for the full screen view of Google Chrome. And the only way to leave full screen is to press F11 again. In this case the tab stacking area which drops down doesn't appear at all, also the exit full screen option which too drops down also does not appear. It seems Compiz is blocking all of those interactive buttons like the floating control panel in VLC and Tab stacking area in Chrome.

Server :: Setting Up A Cluster Specifically For 3D Video Rendering?

Nov 1, 2010

I'm planning on setting up a server cluster specifically for 3D video rendering. In order to maximize speed I wanna use OpenGL hardware acceleration for that and I'm pretty sure that I have to use an NVIDIA video card if I want the whole thing working reliably. Will I be able to start an X-Server with GLX on an NVIDIA video card that doesn't have a monitor connected to it? And what will be the maximum "virtual" display resolution that I can use?

Since I wanna have several servers running side-by-side I really don't have the room for any monitors.Just to avoid misunderstandings: It is not my intention to show what's being rendered to anyone in real time. I will only create video files that can be downloaded later. I'm already pretty sure that this will work, probably using "CustomEDID" or something like that, but I don't have a suitable setup available to test it right now.

Ubuntu :: Skype Rendering - Image From My Webcam Is Clear But The Video From The Person On The Other End Is Messed Up

Feb 13, 2011

whenever I video chat with someone the image from my webcam is clear but the video from the person on the other end is messed up. It is as if it does not render correctly, it's washed out and it looks like a full image and 2 cut off images, one on the bottom and one the top of the full image. Has anyone else encountered this? The PC has a Radeon 9800 Pro AGP card with the ATI drivers installed. Other video plays fine, ....., dvd, avi and mkvs.

Ubuntu Multimedia :: 10.04 Fglrx Bad Rendering In Gdm And Without Desktop Effects?

Dec 23, 2010

My new machine with a fresh install of Lucid boots up and displays the standard gdm login screen showing the list of users which looks fine. After you hover over a name or other option menus on the display, the pop-up or screen change is rendered poorly. It very slowly fixes itself over time. After I login everything works just fine even with the extra "desktop effects" I recently discovered that if I set the desktop effects to none, I get the same effect on my desktop. I've attached a screen capture to illustrate what I see but find hard to describe. The little horizontal bars will gradually be fixed over a minute or so. Dragging the window around smears that effect around the screen. I've been sniffing around the web off and on for a couple months now but haven't found anything that sounds similar.

Now for some hopefully helpful configuration data: This system is based on an Asus M4A89GTD PRO/USB3 motherboard with integrated ATI radeon video, and a 6 core processor. Lucid 32bit.

Ubuntu Multimedia :: Enable Hardware Rendering On Radeon 7000?

Dec 24, 2010

So here is my problem In short, I am having trouble enabling hardware rendering on my Radeon 7000. As a result, games run slow, and Compiz refuses to run. ATI Radeon 7000, uses the open-source driver that already comes installed (Mesa, I think it is called) Here are outputs of different commands I think you might find useful. Let me know if you want anything else.

$ lspci |grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]
$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Mesa X11

Ubuntu Multimedia :: Compiz - Config Not Working - Check Says No Rendering In Use

Feb 9, 2011

i have ubuntu studio 10.04 installed and this is my second installation of the system. now that i have updated the system, got the fglrx drivers for my ATI HD5750, installed compiz-config-settings and glx-dock (aka cairo-dock). the first time i started the glx-dock, half of the dock was visible and it was distorted all over. so i ran compiz-config-settings for the first time and saw that it wasn't also working. then i tried to find a solution for a few valuable hours because it was essential to customize the feel of an OS but i think i have came to a point that i should stop trying to learn things that i see for the first time but ask and hope for the best (soon). anyway i should say that compiz and cairo dock was working the first time i installed the system. now when i run compiz-check, it gives the following output:

Code: Gathering information about your system...

Distribution: Ubuntu 10.04
Desktop environment: GNOME
Graphics chip: ATI Technologies Inc Device 68be
Driver in use: fglrx
Rendering method: None

Checking if it's possible to run Compiz on your system... [SKIP]
Checking for hardware/setup problems... [SKIP]

At least one check had to be skipped: Error: No rendering method in use (AIGLX, Xgl or Nvidia) ok AIGLX doesn't start, so i check Xorg.0.log and it says: (it has loaded and initialised AIGLX but maybe i misunderstand something, anyway you should see for yourself)

Debian Multimedia :: Compiz With NVidia - White Bars And Screwed Rendering

Feb 12, 2010

I installed compiz with nvidia trouble is when I run compiz white bars or lines (bars) appear in open windows (icewease, gedit, etc.). They disappear after a few moment and reappear when scrolling a page. BTW everything works fine with metacity running as window manager.

Here is my xorg.conf:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (randy@juliet2) Fri Sep 5 15:03:39 PDT 2008

Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection .....

I have the nvidia driver 173.14.09 installed. Running Debian Lenny stable x64 and turion x2 with a geforce 8200M G graphics card with dual screens. I first installed the debian repos compiz, then upgraded to the tuxfamily repo version. I installed the nvidia driver 190 from nvidia's website and that fixed it!

Debian Multimedia :: Weird Content Rendering With Iceweasel - Can't Click On Any Of The Links

Jun 7, 2011

Alright ... recently switched from Ubuntu with FF 4.0 to Debian with Iceweasel which I had to upgrade to 4.0 since I really liked the way it worked on Ubu 10.10 ... but I'm having some really strange rendering issues. Flash is not a problem at all, works fine on all flash sites that I've checked out. Some sites though, including this Debian forum, do not show everything in the Iceweasel browser window.

For example, sometimes I'll be browsing on a page with huge chunks of white, clearly indicating that "something" should be in those spaces. When I look at those same pages with Chrome or Opera, everything is filled the way it should be ... all content is displaying properly.

On some sites, like this forum, the rendering is even worse because not only do some items not show up, but in addition most of the links don't work at all. For example, if I use Iceweasel 4.0 to look at the board index of this forum, I can't click on any of the links, not the links in the main sections anyway. If I open up Chrome (that's what I'm using to write this) or Opera, the problem is gone.

What the heck is going on, does anyone know? Is this an Iceweasel bug? Am I missing some package update? I'd hate to have to switch my preferred browser just because this weirdness is going on. At first I thought it was a fluke, specific to a site or two only, but at this point I've seen these rendering issues on about 10 sites ...

Debian Multimedia :: Iceweasel Page Rendering - Not Displaying Portions Of Pages Properly ?

Jun 10, 2011

I guess this is a part deux, since I already posted one rendering issue which was eventually resolved ... having to do with the themes of this Debian Forum. Well, I don't know if this is related to that, but yesterday I noticed on another site that my Iceweasel 4.01 is not displaying portions of pages properly. See attached images. Both Chrome & Opera display that page correctly, I've included a screenshot of the same page with Chrome. I have JAVA installed and everything works perfectly fine accross the board on all browsers, except for this "once in a while" issue with Iceweasel. I've noticed this "missing content oddity" on three sites so far (out of 50 or more). No problem with eBay, craigslist, paypal, and other major players.

Open the images with a new tab, then compare both images side by side for best results.

Chrome: [url]

Ubuntu :: Pdftotext Rendering Between OS?

Feb 10, 2011

I had a working pdftotext script working and custom made a parser for the info in it, but upon moving from CentOS 5.5 to Ubuntu (version unknown) and installing poppler-utils, pdftotext works, but the rendering is different by quite a bit causing a ton of issues. I also tried on another CentOS (5.2 this time) and it rendered the same as Ubuntu. I'm trying to figure out the problem so it renders the same, I'm using the same code and everything.

Ubuntu :: Rendering Of Characters In Firefox?

Jan 29, 2011

I have a weird issue in Firefox on Ubuntu 10.10, and sadly it's a periodic mistake that I don't know how to initiate... Sometime in firefox some of the characters seems not fully rendered, and as I recall it can also happen in menu fonts sometimes. In the attached screen-shot you can see that it's the a character that has the problem - but only for one font type or? But I have seen this with most characters I think - and as stated this happens randomly.For instance right now I looked again in the tab in firefox where I just 5 minutes ago did the screen-shot and now all characters are correct?? I have tried to reload or even restart firefox when it occurs, but this is now guaranty for a solution... When it happens it makes many homepages unreadable

Ubuntu :: (10.10) Differences In Font Rendering Between Qt And Gtk?

Mar 7, 2011

I've got a slight problem here, and have had it for a while: When I use the "Sharp'N'Clear" .fonts.conf from Here, and set an optimized font like Arial, gtk-based applications render correctly, while Qt-based ones don't As you can see, the top window(Firefox) has it's fonts clean and nice. The bottom one(Dolphin) does not. Both are set to Arial 9. I've tried it with a number of different applications, including some custom PyQt4 stuff, and it's clear that it's -all- Qt-based applications and not just one or two.

For further information, I've had this problem ever since I upgraded from Kubuntu 9.10 a while back - That version worked correctly on both Qt and gtk, but nothing since has.

OpenSUSE :: Kdenlive Not Rendering DVD

Mar 29, 2011

Having upgraded to from 11.3 to 11.4 I now am unable to render in KDENLIVE. I've installed MLT, FFMPEG and KDELIVE with dependencies from Packman.

What is different from my 11.3 install is MLT has moved up a notch. 0.5.10 to 0.6.2. Does 0.6.2 work with KDENLIVE 0.7.8? I would think it should.

I have see MLT 0.7.0 is released but will wait for the RPM to be released on Packman.

This is the message taken from terminal.

Ubuntu :: Fonts Not Rendering Properly In KDE Applications

Jan 25, 2010

I've seen a few people are having this issue, so i wanted to start a main thread. My problem started... After installing qt4-designer onto my Ubuntu 9.10 Gnome OS, the fonts in certain applications looked distorted like enlarged bitmaps. I tried uninstalling designer, reinstalling components, using qt4-config to restore fonts, but nothing has fixed this issue.

The issue seems to be specific to KDE applications such as: qt4-config, Amarok v2.2.0, skype, akonaditray, ktorrent, etc. Also, in qt4-config it seems to be specific to fonts between the sizes 9 to 12 inclusive for all font faces. All other font sizes seem to be okay. I've attached some examples.

When i first tried to install qt4-designer, it indicated the following dependancies: fontconfig-config libfontconfig1 libfontconfig1-dev When i try to remove fontconfig-config, it indicates that it is dependent on nearly every application in my system (including drivers and xscreen). Hence, I would need to uninstall everything and reinstall everything!?
