Ubuntu Multimedia :: Mini-lag When Viewing Video Looks Like It's A Few Frames Too Little Per Sec
May 3, 2011
I have Ubuntu 11.04 on a Dell Studio XPS 1640 with ATI graphics and the fglrx driver. It's a powerful machine and I've had no problem what so ever to watch full hd videos on windows 7 but all videos, no matter the resolution, has a very small stutter which is annoying but not making the videos unviewable. But I'd prefer not having it at all. I have tried setting the VLC video output to x11 but there is no difference. It's a screen tearing problem, that was fixed by setting the option "Tear Free" on in ATI Catalyst Control Center.
i want to connect two videos into one. let's take two videos from videos as an example. i want my final video to have the height = height of first video + height of second video and width = max(width of first video, width of second video). in the upper part the first video is played whereas in the lower part the second video is played.
do you know how to do it under linux, the best possibility while using mencoder, ffmpeg or any other command line command?
I've been working on a small program to perform a very specific and useful task of quickly and efficiently converting videos to go on any Apple Ipod or Iphone. This includes both classic and 5th generation Ipods as well. Ibulk is a command-line only program but incredibly easy to use and runs off FFmpeg with AAC functionality. The program comes with a Read Me file which will explain its options and instructions in concise detail. Ibulk converts several videos in its input folder to the desired H.264 or XviD video encoding to its output folder. All videos are created in mp4 format with 160Kbps 48000Hz audio sound quality (highest setting an Ipod can handle) and both video encoders at the highest bitrate an Ipod can handle with the exception of some videos which will be auto-adjusted to meet the Ipod's requirements. Ibulk is written in the native unix/linux language and so it should work on any linux distro.
I've been goign nuts trying to find the source of this niggling problem I've had since upgrading to Maverick. Whenever I'm watching anything I will get these short freezes of about half a second before he file continues playing. It will happen on average 3-4 times per hour on a video file.
For MP3 playback it's even worse, I'll get a stutter every couple of minutes, sometimes several in the same song. I reformatted completely and installed Maverick from scratch. For about a day I thought I had it sorted but then it started happening again.
I checked dmesg and there are a number of worrying lines like this:

The thing is that this problem occurs on all three of my hard drives (2 SATA, one IDE) so it's extremely unlikely all three have become damaged on the day I updated. Could this be a kernel problem of some sort? On an unrelated note all but one of my USB ports fails to recognise any portable music players.
I m watching matches through a website and my laptop understands this situation to be inactive. It s kind of anoying... When I do it in windows, it s not happening, I guess because windows detects I m watching a video. This is happening in both firefox and chromium. Is there anywere to make this not to happen?
I've just watched a video (on the Australian ABC web site: [URL] with the video at [URL] from inside Firefox (3.0.15), and now my Linux (8.0.4) display is mangled.The entire display is moved left and up about 2 inches on a (I think) 15 inch screen. In the vertical direction it is "wrapped" so I can still see my toolbar. It is not wrapped in the horizontal direction, so there is a black bar down the right hand side of my screen. It is as if the wrong screen size is saved.
This isn't just in my desktop environment - it goes wrong as soon as I boot into Ubuntu Linux. But my monitor itself is OK - the display is correct in GRUB and Windows.Since the problem does not go away on reboot (or power down), I assume some file has been corrupted. Where would that file be and how would I fix it?
I'm getting dropped frames from both Digital8 & MiniDV camcorders using Kino. MyCPU doesn't seem to be spiking. I've made sure compiz is disabled and no memory/cpu hungry apps are running. I'm using SATA drives so DMA shouldn't be the issue.
The video and audio that is captured seems to be fine.
I have been trying to view streaming video ([URL]) on my LCD TV (Sony KDL-40V5100). The video is dropping frames when I view in full screen mode. I am currently running with Ubuntu 9.10 and have installed both the Adobe plug-ins.
I have downloaded a film from a commercial TV station for my own use and want to edit out all the advertising breaks. I have tried Cinelerra but I cannot find a means of deleting selected frames, I also looked at trying to use Kdenlive but cannot find a way of loading the complete film to work on so unable to tell whether it might be useful.
the problem i am experiencing on my laptop (hp pavillion zv5000) which runs ubuntustudio 9.10 (this problem also occurred with ubuntu 9.10, before i upgraded to ubuntu studio) is that whenever i view a video on firefox, be it videos, metacafe, and generally any site where you can see online videos, the video glitches a lot, and after a few seconds firefox grays out, and is not responsive, which means i either have to kill firefox.i am running firefox 3.5.7 with the ubuntu firefox modifications 0.8 pack added. in the preferences, on the content tab the enable java button is not ticked. the following is the list of plugins i have on firefox:
i've got a dell mini 10 w/ 9.10 nbr on it, and videos played in either totem or vlc won't play, and result in the player crashing. it almost crashes the whole desktop. i can usually recover from ctrl-alt-f1 and killing the process or restarting the gui.
i've got no idea how to fix it. it's got a gma500 and that poulsubo (sp?) video driver. flash works reasonably well for a netbook though. i can watch videos vids ok- just have ot shy away from full screen videos, and especially not get tempted by full screen hi-def videos...
how it is possible to watch the superbowl on linux natively? I am in charge of the computers at a school for mainly american students who are studying in my country, the school wants to enable them to watch the superbowl, tehy gave me a page with system requirements which seemed to suggest that it was just a flash movie player.
However when actually browsing to the demo I was confronted with an OS warning, at first I thought it was just a "stupid" me message like Yahoo-mail telling you that they haven't tested the rich version on your OS, but when browsing there with useragent set to winXP it turns out that you need the "MoveMediaPlayer". If left with no choice I guess I will install it together with firefox in wine, but I'd much rather have a different solution, also does anyone know if this player works well in wine?
No progress viewing input yet in Linux. I installed MythTV, VLC, and no luck yet with vids or sound.I had video input with Windows Movie Maker, and Media Player Classic (3rd party), but no sound in either.
Is it possible to prevent "unable to connect" messages from appearing instead of blocked web-content? I am using a huge hosts file to block unwanted web content from appearing. The attachment illustrates what I am referring to.
I've been using ubuntu for several years now and one thing I've always have had problems with is getting a smooth picture when viewing videos. I currently have an amd dual core 2.2ghz processor and a H3200 ati graphics card which is more than capable of playing HD and blu ray perfectly in windows. I'm running ubuntu 9.10 with the latest graphics drivers 10.2. If I can movies etc., to play without lag etc., I can finally delete my windows partition. I want to avoid using a virtual machine for now.
I found a few threads dealing with this subject about a year ago but none seem to have come up with a simple answer. I use vlc and one writer indicated there was an option in vlc to disable the screensaver when in full screen mode. However, I've checked all over vlc and can't find this option.I'm not interested in creating a switch using Terminal to do this manually. I just want to know if disabling the screensaver can be automatic when in full screen mode - like in Windows
I am just asking because i want to be sure, that sensitive data can not be extracted from my computer unencrypted, using cached files. For instance i would not want my girlfriend's picture to be uploaded to some random site, whereas it normally stays on an AES encrypted volume, but i viewed it once, so it was available in some cache folder, unencrypted - yea, sadly, it happened in windows -.
I have distorted sound when viewing SWF files on browsers. Tried both chrome and iceweasel. I have a Dell XPS with debian testing (64 bit), alsa is 1.0.23. Sound is working properly when playing formats other than swf.
It stretches the parts of the 3d object to the sides of the viewing area. This makes Google Earth almost impossible to use. I have a video of Google Earth's problem here: [URL] Here's a screenshot of it in GLChess: screenshot_001.jpg I am running Ubuntu 10.06 Lucid Lynx on an old HP dv5000 laptop. It has ATI Radeon graphics.
I usually use dvgrab to make an .avi file from the video on our mini dv camcorder and save it to my pocket drive.
Right now I edit this from the pocket drive in Windows 7 on my laptop with Sony's Vegas movie studio HD 9.0 I'm having issues with the laptop lately and with out bogging down in too many details I have to burn the edited video back to the mini DV tape and transfer speeds are causing me problems.
Is there a Linux video editing software that would let me export back to the camcorder? OpenShot doesn't seem to have that option and from what I remember of PiTiVi it doesn't either.
just got this netbook like 2 days and tried out windows 7 which it came with but hated it so i switched to ubuntu netbook remix but i noticed i cant use skype on it which is pretty important for me. i basically just reinstalled it and or osme reason it worked this time
I am trying to get the Asus "My Cinema-U3100 Mini plus" DVB-T USB stick to work on my lucid 32bit with 2.6.32-27 kernel - with no great success so far. And this despite searching through forums and following the instructions given on [URL].
The USBID is in fact Code: ID 0b05:1779 ASUSTek Computer, Inc. Which is exactly the one shown in the list of supported devices on LinuxTV. I have implemented all modifications and corrections to the source files as outlined in the above LinuxTVWiki instructions.
I also added the boot option Code: usbhid.quirks=0x0b05:0x1779:0x0004 to grub2 in order to overcome the (initial) problem of the tuner being recognised as a HID device.
My dmesg output after plugging in the device now shows Code: Jan 27 17:44:50 jens-laptop kernel: [ 1086.358488] usb 2-5: new high speed USB device using ehci_hcd and address 6 Jan 27 17:44:50 jens-laptop kernel: [ 1086.495359] usb 2-5: configuration #1 chosen from 1 choice

My knowledge is limited and I have no idea why I am getting all these warnings and finally the error message. Also, is there a way to tell when (or if at all) driver support for this device will be implemented in the Linux kernel?
I'm trying to run Wammu with sony ericsson xperia x10 mini (usb cable), the SD card inside the phone appears but I can't get something like /dev/ttyACM to communicate with the phone.
(It's ubuntu, generic kernel with all stuffs and I had had a samsunng phone working in the past)
I am stuck in 800x576 resolution and don't know how to escape. I've tried changing xorg.conf but that caused my machine to grind to a halt and I had to copy the original .conf file back over before I could launch GNOME again. I've run lspci | grep VGA, and this is what I get:
00:02.0 VGA compatible controller: Intel Corporation System Controller Hub (SCH Poulsbo) Graphics Controller (rev 07) When I run xrandr --verbose, I get:

I'm trying to install Photran for Eclipse 3.6. I've managed to get 3.6 and it works but the next step involves choosing a package that I just can't see because my screen resolution is too small.
I've managed to install openSuse 11.4, and have also managed to get the sound working properly, but the mic doesn't seem to be working.
My system is a hp mini 110 3000 netbook which came pre installed with windows 7. I'd install ubuntu on this before switching to openSuse, and in ubuntu the mic was working.
Also, I can't get bluetooth and the sd card reader working. I've got the ath9k driver installed, and WLAN works perfectly on that, but bluetooth doesn't.
I have a Dell mini 10 netbook that I am trying to set up as a temporary HTPC. Using XP, I can send the video and audio over the HDMI connection, but when I attempt to do so from Ubuntu, there is not an option for a different monitor.
