Ubuntu Multimedia :: Audio Plays Fine, But The Video Jumps And Can't Get A Clean Picture Except For Maybe 15% Of The Time?
Jan 1, 2010
I have 9.04 and I recently "got" a 13.2GB 1080p HD movie. When I try to play it, it's choppy and mosaic like. The audio plays fine, but the video jumps and I can't get a clean picture except for maybe 15% of the time. I have to hold down the spacebar so it plays and pauses very quickly for the video to even proceed. I've updates VLC and Movie Player and I've downloaded many codecs and I can't seem to fix it.EDIT: I can play it in Movie Player without the pixel/mosaic-like effect, but it too is extremely choppy.
I have recently swapped over to debian (KDE 32bit) from linux mint, however vlc only plays audio, no video (This is for .avi's, .wmv's and rtsp streams, probably others but that what i have available to try). I've installed debian multimedia and dragon player will play .avi's fine, though crashes with .wmv's .
Output if i start play a video vlc through terminal VLC media player 1.1.3 The Luggage (revision exported) Blocked: call to unsetenv("DBUS_ACTIVATION_ADDRESS")
Got this weird problem. I just installed 10.10 to my Thinkpad W510. I am trying to install the proper codecs required to play .avi and other files. I can hear sound, but no vide
I can play a video on XP, but there's no audio in Lucid. The hardware is a Lenovo SL400, 2GB RAM, 7200rpm drive w/ 36GB free, and an Intel T5870 Core 2 Duo 2GHz CPU.Media player and Banshee fails to play the video with the error messageNo packages with the requested plugins foundThe requested plugins areWindows Media Audio 9
Avidemux crashes when I try to open the 6.3GB file, which I can play with audio AOK in XP. Assert failed :_offset<=pakSize at line 352, file /build/buildd/avidemux-2.5.2/avidemux/ADM_inputs/ADM_asf
I'm having a really random intermittent fault with video files... all kinds... and also happens with different media players... they lock up the entire system but when i reboot they'll play fine...could this be the graphics card? it's a Sparkle Nvidia Geforce 9500.... is there any reccomendations for a suitable replacement that doesn't cost the earth... I'm looking at starting 3D animation too, so was looking to upgrade anyway...there was some kind of error that randomly popped up once or twice when it was playing files...
i was tweaking some settings on mplayer and now when the video is playing fine the audio is gone, not only from mplayer but also from all the applications
I can't play video on any player (vlc, mplayer, totem), the files open, sound works, but video is black. I suspect something went wrong when I upgraded to VLC 1.1.4 using a ppa, I've read that the ffmpeg can screw up and then video just stops. Trying to play m4v, mkv, avi, none work.
Not sure what to do, reinstalling seems like a hassle. Already tried removing vlc and the new ppa, tried removing ffmpeg and reinstalling, removing ubuntu-restricted-extras.
I recently switched my usb external soundcard from an M-Audio Fast Track Pro to an Edirol UA-25EX (i can get 24bit working on it - that's why). After making the switch, all audio programs are working just fine except for Audacious. When i try to play audio, i get 00:00 and no playing. The output plugin is ALSA and the audio device is UA-25EX. I don't understand why it's not playing the audio.
My partner is a teacher and has downloaded some videos from a teacher's resource site but can't seem to play them in Ubuntu. They play fine in Windows XP using Windows Media Player but they only play a few seconds in VLC or Totem and then freeze. The files in question seem to be normal MPG (MPEG-1) video files but somehow VLC and Totem choke on them. I have installed all restricted video formats including w32codecs but still no joy. My partner is threatening to go back to Windows!
I was setting up my Totem Movie Player on Ubuntu 9.10 and at first it wouldn't play dvds at all. So, I went online and entered these two commands into the terminal to play restricted dvds.
DVDs will now play on Totem, but now I don't have any video. I can hear sound and if click around the screen I can get it to play but I still don't have any video. I also tried both dvd drives on my computer and tried different DVDs. Still same thing.
I got my video files from my external hard drive to play, except that all the video's are all negative. Is there a setting to adjust this? I tyred to to go threw the player and see if I changed the settings some how.I even tried other players. I had been watching ..... videos earlier, it was a little choppy video but colours were fine, then I think loaded the flash players and after that the colour went to negative.
I have a WMV video which plays in XP but fails in 32-bit Ubuntu Lucid (same machine, dual boot), kernel 2.6.32-22 on a Lenovo SL400 w/ 2GB RAM, 36GB HD free and an Intel Core 2 Duo T5870 2GHz CPU.

I just installed Mythbuntu on my old laptop (lenovo with on board graphics card). I have now the problem that when I connect the TV out to my TV the picture is flickering. It looks like the image is sometimes jumping to the left or right for a fraction of a second. This usually happens when the image is not still, ie I scroll the menue or a movie is playing. I already tried different display settings but that didn't help.
I am having problems: videos have sound, but no picture.I'm using a Gigabyte motherboard with integrated ATI video, and I've read before that XBMC (and Ubuntu in general) don't like ATI too much. Is there any hope left to make XBMC work?I've tried the following:1. Fresh Ubuntu installation, default ATI drivers. Result: when starting a video, audio is okay, but no video. Also, visibly slow graphics even while navigating XBMC menus
2. Installed ATI/AMD proprietary FGLRX driver via System->Hardware drivers. Result: significantly accelerated menu navigation, but no video still. Note: having no problems watching videos via VLC or Totem Movie Player (after downloading proper codecs)3. Fresh Ubuntu installation, then downloaded and installed ATI's proprietary Linux drivers from ATI's site (ati-driver-installer-10-7-x86.x86_64.run). Result: yippee, I see some video, but wait: no color!! (all videos are in sepia-like mode)
4. Followed these instructions to install the unofficial ATI drivers. Result: total failure, XBMC won't even start, says something about the need to have proper hardware OpenGL acceleration.System info:GIGABYTE GA-MA785GMT-UD2H AM3 AMD 785G mobo with ATI Radeon HD 4200 onboard graphicsAMD Phenom II X2 550 processor4 gigs of DDR3 RAM Ubuntu Lucid 32 bit (2.6.32-24-generic-pae)
To start off, I am about 3 days into my new ubuntu operating system. I am a complete newbie, but i have picked up alot in the last couple days. My sound was previously working, but the microphone was glitching when using skype. After running a bunch of different commands in terminal that were posted on forums from all over the internet, I rebooted my computer to find no sound. I have searched the forums again and tried many different command lines in terminal to no avail. My system setup is found here: [URL]
Essentially, what I am attempting to do is set up an older PC with a Radeon 9600 video card chipset in it with xubuntu 9.10. I would like to attach this PC to my rear projection tv (Sony KP-48S75) via an S-video cable and use this TV as the primary and only monitor for the system. At one point, I had Ubuntu 8.04 hacked onto this same hardware fulfilling this role decently. However, due to some carelessness on my part, the system became unstable and I decided to start anew (random crashes, lots of X freezes, dependency issues, screwing too much with my sources.list and so on). So, that said, I installed Xubuntu 9.10 on the PC and had it hooked up to both an LCD monitor and the TV via S-video. Upon boot, both outputs worked, though X only rendered on the LCD and not the TV. Thus, I dug and researched and found that by putting a bunch of xrandr commands into my gdm start script I could finagle the TV into displaying my output, mostly.
The commands I used to get the S-video out work (and, therefore, pasted into my /etc/gdm/Init/Default script) follow: Code: xrandr --output S-video --set load_detection 1 xrandr --output S-video --set tv_standard ntsc xrandr --output S-video --set tv_horizontal_position -2 xrandr --addmode S-video 800x600 xrandr --output S-video --mode 800x600 xrandr --output S-video --rate 60 xrandr --output VGA-0 --off
You'll notice I do a few things in those commands. First, I set load_detection to 1 in hopes of enabling automatic S-video connection detection (this isn't working). The next interesting bit is my commanding the horizontal position. The reason I had to do this is, because, upon getting the S-video output to render, the picture rendered to the right-hand side of the screen, deprecating the furthermost bits (for instance, I cannot see the shutdown icon in the upper right hand corner). Setting the horizontal position to -2 allowed me to shift the display to the left a bit, but, to my surprise, the right hand side still deprecates and I am just left with a black column on the right hand side.
Question 2 has to do with the screen indexing. If I run a xrandr command with no options, I see VGA-0 indexed as Screen 0. I also see the S-video listed as disabled (even though I see it rendering on the TV right in front of me). Finally, I notice that, under the VGA-0 section, there is a screen size listed, as well as several resolution modes with many parameters following them (like 800x600 72.2*+ 75.0 .... some other stuff). However, under the S-video section all I see is one mode with one small bit after it (800x600 72.2*). This smacks of suspicion to me and makes me think it might be related to the right side of my screen being deprecated. My wager is that I need to tweak some modelines in the S-video output so that it is more in sync.
However, I do not know the syntax for modeline editing and, since the S-video screen isn't even detected, I am not sure I really can edit these options. Does anyone know why my S-video output would continue to be listed as disabled even when its running? Furthermore, can anyone tell me why no screen index is given to the S-video output (I only see screen 0 attached to VGA-0, no screen 1 for S-video)? I think I need the screen indexed properly in order to use the xvattr command later in order to allow xv overlays to function on the proper screen. Finally, I do have a xorg.conf file loaded in /etc/X11 that is mostly hacked together stuff I used trying to get this to work in the first place. Would this conflict with the xrandr setup? Which options override which?
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?
Is there an application that anyone knows about that I can use to convert either an .flv or .ogg file that contains both audio and video to just an audio .ogg file (preferably vorbis+theora) without audacity? I'm fairly certain audacity could accomplish this but it seems like overkill for what I'm trying to do and the computer I'm trying to use does not run it so well.
::EDIT:: I should also mention that I've tried looking on google. I did find downloadhelper extension for firefox which uses ffmpeg to convert the files but I don't see any obvious way to strip the video.

Does this meet the required 4 ports mentioned for alike cameras in the forum posting. If not, I have one of these.. Is this what they are talking about. I have just started thinking about this again and am not sure if I'm asking the right question. I don't want to go buying a bunch of hardware I can not use. So I'm hoping to look to someone here who has some experience in live streaming audio / video to one of the distribution sites.
I just installed Lucid Lynx RC 1 on my MSI Wind U100 netbook. When I tried to play a video on it I was informed of a lack of codecs, so I downloaded my video player of choice: VLC media player. When I tried to play the video, there was audio but the screen was black. The same thing happened when I downloaded to codecs and used the stock video application.
Just installed F15 using preupgrade (from F14) and now, every time I reboot, time jumps backwards 4 hours. If I reboot twice in a row without correcting the time, time will be off by 8 hours. Time zone is set correctly (Eastern Time). "Synchronize date and time over the network" is unchecked.
Since the difference between GMT and Eastern time is 4 hours, there appears to be some confusion over that but I can't find anything in the "Date & Time" app relative to that to try to play with to see if I can correct this. II do remember a similar issue many releases ago but I can't remember how it was dealt with.
I run a mostly untouched CentOS server, nothing is installed except a server app to store data. The server has been crashing lately - after a year of no problems, so I looked into the logs of it and noticed weird discrepancies in the time around the time it crashs. So I started "watch date >> datefile" and this is what happens:
Code: Sun Oct 17 09:52:45 CEST 2010 Sun Oct 17 09:52:47 CEST 2010 Sun Oct 17 09:52:49 CEST 2010
I'm having a problem with the time on one of my servers jumping forward into the future. We run serveral CentOS 5.4 servers running Xen, some up to date and some a little older. The one in question is running 2.6.18-164.el5xen, with xen-libs-3.0.3-94.el5_4.2 and xen-3.0.3-94.el5_4.2. On this server are several Xen virtual machines, also running CentOS 5.4 with kernel 2.6.18-164.el5xen. One in particular has problems with the clock keeping proper time.
We use NTP (ntpd) to sync time to a central server in the company. Our NTP set-up works fine, and we have problems on only a couple of servers out of many. The problem I see is that one one particular Xen virtual machine, the clock will suddenly jump forward into the future, usually by several minutes but once by more than an hour. This has obvious implications for software running on the machine. Software such as Oracle grid control agent will restart itself under the (incorrect) assumption that it has been hung for several minutes with no activity. Oracle database will cope gracefully, but applications that refer to the clock will be confused.
We detect these time jumps because we have Nagios checking the clock on each host against the centralised time server (Nagios's check_ntp plugin). Nagios will suddenly report a clock offset that is miles into the future. Following the time jump, ntpd on the host in question will re-sync the time. Ntpd keeps the time steady, ticking just a few milliseconds per second until real time catches up with the server. i.e. Nagios will report the time as being 10 minutes ahead, then a minute later the host will be 9 minutes ahead, and then a further minute later the host will be 8 minutes ahead of real time. The clock on the host stays running very slow until it eventually is correct.
under avidemux-qt, the videos play and encode w/out any audio output, and audiodevice is set to "dummy" and cannot be changed. but avidemux-gtk has no problem w/ audio playback.Is this an application specific problem, and if not how do i configure phonon to fix this issue?
After upgrade to Slackware 13.0 (then 13.1, then -current) I still have problems using the secondary video output on my old and trusted Toshiba Satellite (Intel chipset 852GM/855GM). This used to work with Slackware 12.x! The problem manifests itself by jumpiness on the secondary port. The jumps appear with any video update (eg. window focusing, but also with the updates from the Clock or the CPU graph).
This is very annoying, particularly because I use this machine to teach. In only one combination (with a NEC NP-100 projector) I can solve the problem by reprogramming the Framerate to 70 or 75 Hz. After reading many mails and references on the 'net, testing a lot of the solutions to no avail, I'm more confused than ever. And no visible improvement either. Here are a couple of the tests I did:
1) I added i915.modeset=1 to LILO. This helped in the sense that now, in text mode, the 2nd video output remains working, which is slightly useful. But no improvement after startx.
2) Xorg.0.log says:
(II) intel: Driver for Intel.....
then, continues with:
(II) VESA: driver for VESA chipsets: vesa
Why are both drivers signalled here? (solved this by generating a new config with Xorg -configure, but no difference)
3) The intel driver says (in Xorg.log): compiled for 1.7.6, while X -version says 1.7.7 (is this significant?)
4) After this, the line
(EE) intel(1): No kernel modesetting driver detected appears in the Xorg log. This wasn't there when no xorg.conf was present.
5) On the other hand, without an xorg.conf, there was a line complaining about a missing 'fbdev', this seems solved afterwards.
6) Just in case, tried software cursor on/off.
7) Maybe unrelated: After enabling modesetting (which should have been enabled by default),LCD brightness resumes correctly after 'sleep'(before, it would switch to low brightness every time).
As an arranger of collegiate a cappella music, I often times need to listen to a song as I'm playing with a midi sequencer or some arranging software. On Ubuntu, since Gutsy, I've often run into the same problem from distribution to distribution:
Midi and audio won't work at the same time. If I have an audio file open on VLC or FireFox, I can't play Midi sequences on my arrangement. If I'm arranging and listening to Midi notes, I can't play music. Note that it's incredibly inconvenient to constantly close one so I can play the other to finish arrangements.
