Ubuntu Multimedia :: Video Playback Freezes Screen Randomly While Sound & Keyboard Works
Feb 12, 2010
i'm using ubuntu since 8.04, and the current (9.10) is a fresh install on new hdd.the problem was the same each version (8.04, 8.10, 9.04, 9.10) - while i'm playing the video (no matter if i use mplayer [smplayer], gstreamer [totem] or adobe flash plugin [videos]) the playback freezes randomly for about 5-10 sec. during the freeze the movie is still played, i can hear the sound is ok. if i press [space] in smplayer it pauses the playback, so the responses for keyboard actions are ok. not for the mouse clicks however. i can still move the cursor around the screen but it seems the system is not aware of it (clicking on the "pause" button doesnt pause the movie). except the cursor, nothing changes on the screen (if the im [pidgin] window was blinking because of new message, it freezes etc etc).
is there any kind of log i could look into just to try figuring out the problem?it is impossible to watch any movie on my pc (currently i don't have tv)i installed windows on external hdd once and it played videos fine so i suppose it's not hardware problem .

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 really don't know where I should ask this question. When I'm watching a video in full screen (ex, avi or h264 file) I am seeing random horizontal bars where there is action on the video like where a head is turning.When the motion is slow I am less likely to see these lines. Faster the motion, lots of lines or shaky motion. I was using my onboard Geforce 6150 GPU but thought it was because it was underpowered. I then bought a GT220 thinking that it was the problem. It is still but less frequent. Using the built in player, VLC... I don't know where to look, what to search for...There is my setup:
AMD Athlon II x2 255
4GB DDR3
nvidia GT220 512mb

I'm using Gnome as my desktop environment in Debian stable, I have previously address this issue at another post with the solution of setting xset command to disable screen blanking. However I'm still looking for a method that can automatically disable screen fade while watching videos in a browser. I don't want to permanently disable the powersaving idle method. I have both cpufreqd and laptop-mode-tools to conserve my powers.

I made a mistake and bought a $50 IBM A50 to use as a media server...Installed Karmic on it and figured out that the video card couldn't handle anything beyond the factory setting of 800:600, something like that...
I have not taken the time to learn about video cards and now I suffer....I found this "solution" EVGA 256-P1-N399-LX GeForce 6200 256MB 64-bit GDDR2 PCI Video Card
Which has mixed reviews on newegg
I want to use this machines( or another) to playback movies on my flat screen. I suppose I need to find out more about my TV as well...

I have no problem playing all videos and sound files. I have installed most codecs and propriety software. I can play all downloaded .flv videos from all the sites except one. When I open the .flv file from this site, I get "internal data stream error."

I've been an Ubuntu user for a couple of years. I have a Sony Vaio VPCCW-2S1E laptop, with an Nvidia GT330M graphics card. I had worked with Karmic, Lucid and Maverick on this laptop without any problems, until recently, when I had to re-install Maverick.
Now my laptop keeps freezing entirely (no response whatsoever), with two keyboard lights blinking. This happens randomly: sometimes I'm doing something, other times the laptop's completely idle. Sometimes the screen display turns off on freezing, other times not.

I have installed Ubuntu 10.10 on other machines before and have not experienced this problem. Occasionally, the system will lock up. They keyboard and mouse stop responding (my keyboard status lights no longer respond, but my optical mouse light is still on). I can ssh to the machine, and it seems to work as normal. I kill processes that are open on my desktop through ssh, (i.e., Firefox), and I notice when I switch back, I still have the same frozen image on my screen. I have looked at the following files to determine any issues with the GPU:

I am using Debian with a gnome desktop.
Code: Select alluname -a
returns
Code: Select allLinux app-server 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u1 x86_64 GNU/Linux
My desktop sometimes freezes and does not respond to keyboard or mouse. I initially thought the CPU was overheating but it froze tonight when my CPU temperature was 32C and it has been up to 50C without freezing. I am beginning to think it is a software issue rather than a hardware issue but do not know. I looked at the pm-powersave.log and user.log but did not see anything suspicious.

I am using ubuntu 10.10 on Dell Inspiron 1525 dual boot with vista. My concern is streaming online videos through websites such as BBC iplayer, sky news, ....., NDTV news channel, etc. Videos are streaming perfectly fine as long as they are not running on full screen but if I try to run them on full screen video freezes (after a few minutes, say 5). Interestingly, sound does not stop. I can still hear the latest news updates but the video does not correspond. Same videos are running fine whether full screen or not in vista.

I've been tweaking my kernel for RT performance over the past few days, and just recently, it's begun randomly cutting sound playback, and I can't seem to figure out why.
Was watching a movie last night using VLC, and about 5 minutes in, sound playback just totally stopped while video kept working. Sound driver in VLC was set to Pulseaudio. I switched it to ALSA and the problem seemed fixed.
In Decibel Audio Player, the tracks randomly just stop in the middle of a song occasionally (every 5 songs or so, give or take), and a little red 'X' appears next to the track that got "skipped." Screenshot:

Don't recall it happening before I tweaked all the RT audio settings.

I installed 10.04 beta 2, but have all the updates to this point. Everything freezes randomly. I get a weird pattern across the screen and the mouse and keyboard stop working. From what i can tell, the hard drives just keep spinning at whatever speed they were spinning when the freeze occurred.
I haven't been able to reproduce it on purpose.
I was using an Nvidia 8400 GS and through some reading i thought it might be the nvidia drivers. I tried reinstalling the drivers and still froze randomly. I took out the video card but I realized I have an onboard nvidia chip (GeForce 6150SE nForce 430 rev a2). Drivers or not, it still freezes randomly.

I have a fresh install of 64 bit Squeeze and for a few boots the sound worked great using my motherboards onboard intel audio not the creative soundblaster pci card I also have.
But now sometimes I boot up and get no sound, other times I get sound. I cannot find out why.

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...

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?

I've been running F12 x86_64 for almost a week now without significant issues, until now. I found this annoying problem with the audio system during video playback (both with VLC and with Kaffeine).It happens after a while playing a video: sound just stops (video continues). I found that sound is not dead though (can open Rhythmbox and music sounds).I discovered some system messages in /var/log/messages regarding this (attached).What could be happening

No sound on my Fedora when I play stuff on my hard disk. Video plays but there would be no sound. But there is sound/audio when I start using a browser. So I guess flash is working. Any basic trouble shooting stuff for audio? I tried this [URL] but the stuff is way over my head.

I set up Ubuntu on an old iBook G4, planning to use it as a front end to my main box. Installed 10.04 no problem, and from there, used Software Center to install MythTV Front end. Have done the same thing on a netbook, no problem.
However, on this PPC Mac, the front end works fine, navigation, menus, etc, until I try to play a recorded programme - the screen is blank, and I just get white noise from the speakers.
(BTW am trying Ubuntu as I don't have a Mac OS new enough to get any of the current Mac MythFrontEnd builds working)

I have a gigabyte MB/rig connected to Svideo out on my TV. I have external PC speakers connected to my sound card. For some reason when I go to play video, streaming audio, or streaming video I get no sound. I go into alsamixer via CLI and all is unmuted. I reboot, sound is back. The next day I load boxee, no sound. It's not just boxee when I have no sound. If I close boxee and open vlc and stream online radio, I get no sound either. Reboot, sound is back. No external errors of hardware conflicts either.
Running Ubuntu 10.04, 64bit , kernel 2.6.32-24-generic

I have had some issues since installing Fedora 11 on my desktop (well not after I installed it, once I installed the updates). Anyway sound was cutting out, videos were jumping, speeding up with no sound etc online such as ....., when playing local songs and videos etc. Anyway I followed this guide [URL] and that fixed my playing of online videos, music and when I play local music in totem etc. IN fact there is no issues with sound in those.
However; when I try to play a local video in any medial player it jumps sound, crashes, if it starts playing sound it will cut out and if I move the video forward it cuts out and sometimes crashes the video player. Any ideas why that guide fixed all online video and local MP3 but is till messed up playing local videos?

I have upgraded from 9.04 to 9.10. Both playback and record were working using only ALSA. Karmic installed PulseAudio. Looking around the forums I found a post on how to update to the latest ALSA driver (+ lib + utils) and remove pulse to take it out of the equation. With or without pulse I cannot get record working. For work I need to use my laptop as a softphone. I've tested my headset on another machine - headphones and mic both work. Any suggestions on how to resolve this would be greatly appreciated. I have a Thinkpad T61P. Below is the output of some hopefully useful commands ...uname -aLinux moes 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 16:20:31 UTC 2009 i686 GNU/Linux

I am browsing or chatting with someone or doing whatever, and the screen will randomly go black and the sound will be cut off as well. The computer doesn't shut off, it's not in Suspend mode. All processes are still running when this happens. And it doesn't come back.

If I start skipping through a movie or song that's playing, sometimes the program will totally freeze. It stops playing audio and video altogether. Similarly, if for instance I'm listening to a music playlist, often times when VLC skips to the next track it stops playing audio, but continues through the track like it's still playing. Once it reaches the end of the first track it had a problem with, it freezes altogether and I have to close the program. In fact, the program stays running even after I "x" out of it, and I have to kill the process in system monitor and restart VLC in order to restore functionality. This happens quite often (as in, a few times a day), and as I'm sure you can imagine, this gets quite annoying, lol.
I've looked in the various logs in Log Viewer, but I don't see any obvious problems. There are no error messages pertaining to VLC, or audio or video output so far as I can tell. I've also tried reinstalling VLC to no avail. I think the next thing I'll try is to remove it completely first, and then reinstall it....but if that doesn't work, is there anything else you guys think I should be looking at? Lucid is the first Ubuntu release that's worked well for me (9.04 and 9.10 had serious issues on my machine) so I'd like not to revert back to an older release just for VLC if at all possible.

I'm sorry if this was asked before (i know it was but never worked for me) 2 days ago I installed ubuntu 10.10, my very first linux OS and I immediately fell in love with it.The only problem now, is tearing during video playback (I'm a perfectionist with a thing for fine details, so this is literally killing me)
I have nVidia 9200M GS (HP laptop)
I've set nVidia setting to sync vblank and disabled it in compiz
I've also disabled PowerMizer..
I love the system to give up some vsync issues in moving windows, but i just can't get over video tearing. I'm ready to install anything, change anything, even do a new clean install to get it working. UPDATE: Installed SMPlayer, works fine but drops couple of frames every 5 secs or so (more annoying than tearing lol) is there any specific settings that can fix that?

Both MP4 and OGV playback completely weird on my Ubuntu 10.04.2 laptop:
The resolution/length/etc is correct, but the picture is all weird. Webm doesn't work at all.
I tried mplayer, kmplayer, smplayer, gxine, totem and kplayer. All the same.
However, the exact same video's play back normally in HTML5 pages with a bunch of browsers on the same machine. They also play back normally on a Windows machine. There is no DRM involved.
Aren't these gstreamer en mplayer based players supposed to handle this correctly?
This is an Intel Core i3 machine with Intel HD graphics.

I have a Dell Latitude CPi that has 400MHz Intel Processor and 256 MB of ram. It has a Neomagic Corporation NM2360 [MagicMedia 256ZX]. I have it set to 16 bit color depth and it is using the neomagic driver. My problem is that it cannot play any video of any size flash, or saved to hard drive. It has a fps so low that I can see it rendering each frame going across the screen. It doesn't seem to have a problem with animated pictures, just actual video files. I don't know whether or not this matters but the card set is known to not support 3d acceleration. I can run any commands in terminal and have a good understanding of the linux environment. This problem has occurred under Ubuntu and Xubuntu and still happens if I use a light weight WM like fluxbox.

When trying to playback DVDs in VLC media player, I have to switch the video output driver to get any playback.If I leave it on "Default" (which I think is defaulting to "XVideo Extension Video Output"), I get a solid green or blue screen (which I also get with "Xvideo Extension Video Output")If I switch it to "OpenGL Video Output", I get proper DVD playback but it is kind of pixelated and ugly.If I switch it to "X11 Video Output", I get DVD playback that is very crisp and sharp, the image quality is great.unfortunately, the colors are completely messed up and the blue is completely saturated.I've played with the color settings (especially the Hue setting), but I can't get the colors to look right.
I'd really like to use the x11 video output since the quality is the best, but I can't get the colors right.the first one (Screenshot.png) is OpenGL output, and the second (Screenshot-1.png) is X11 output.It's also worth noting that I am on an IBM ThinkPad R32 with an ATI Mobility Radeon 7000 (or M6, or M6 LE, whatever you wanna call it).I'm running a fully updated 9.04 Jaunty installation.
