Ubuntu Multimedia :: Choppy Video Quality - Horizontal Flickering
Jan 16, 2011
I installed Ubuntu 10.10 recently and I love it. Everything works great except for video playing. When I try to play DVD's with VLC or ANY video player, I get horizontal flickering and I can't seem to fix it. I re-downloaded and installed the most recent video drivers from Nvidia and it did not change anything.
My video card:
Code:
I don't know what else to do. When I run windows, the videos play smoothly, just fine. But when I play the same DVD's under Ubuntu, it's choppy.
I'm using 9.10 on acer aspire one (not the netbook remix).im using the default messanger client empathy.everything else works fine but when i try to video chat the video chat begins but if the other person even moves a litte or even nods his head then the video becomes so choppy that u cant see anything and then after 5 min comes back to normal for a second or two.i have all the latest updates and gstreamer0.10-ugly-multiverse which is required for video chat b/w empathy and gtalk.
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 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'm having a problem watching TV on Ubuntu. The video has horizontal lines where there are motions on the video:
Do you know how to get rid of that? I'm using Me TV, and I selected all different deinterlacing types: None | Standard | tvtime but I didn't see any difference.
I'm experiencing occasional flickering of horizontal lines during DVD playback. Another thread suggested turning off the de-interlacing but it is already turned off and turning it on doesn't change anything.
I have an AMD 64x2 4200+ with 3GB RAM running Ubuntu 9.10 64 with on board nVidia 6150SE video. It doesn't seem to matter which player I use (MPlayer, Movie Player, VLC, etc.), so I'm wondering if it may be some sort of video configuration problem.
When I play streaming video on hulu or other sites it is choppy. However, the sound is fine. Video files play fine when I download them.I experience this problem in both Firefox and Chrome. I have a 10MB connection on other Linux desktops the streaming video is fine.I imagine it is a flash issue, but I have the latest flash v10.1.The other solution would be a video downloader for streaming video. I have not found one that works on Linux.
I've got a Lenovo T410 with just the onboard intel graphics, with the i7 620m and 10.04 64-bit installed.I've also added the xorg-edgers ppa and installed all the packages from there. When I try to watch a 720p video full-screen in ..... it is unwatchable, just too choppy. I haven't been able to find an answer to this elsewhere. I've tried disabling the hardware acceleration in flash but that does nothing. It seems that the driver in use is i915. Is that the driver that should be used? From lspci: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

I'm running Ubuntu 11.04, have 4GB of Memory, and an AMD Phenom II X4 840 Quad Core processor.When I play Hulu Desktop the video is choppy.Now, the odd thing is that I had this problem before. It's the whole reason I upgraded my processor. When I upgraded I noticed an improvement, but it was still a little choppy. I then went to the Adobe site and got the latest version of Flash, and lo and behold, I could watch Hulu Desktop on HD quality with no problem!
Im running Xubuntu 9.10 on my compaq v2000 laptop. My problem is that the video stream playback is very choppy. I have tried the method found here [url] but when i get to the part where I have to type "echo base....." when i hit enter my terminal replies with "bash: echo: write error: Invalid argument"...How to fix this choppy video streaming playback...
I just upgraded from Karmic to Lucid. I've never had problems with playing video files before, but now that I've upgraded to Lucid, I am, regardless of Compiz and other visual effects being on. What I know of my hardware specs are in my sig. I have "NVIDIA accelerated graphics driver (version current) [Recommended]" activated (and in fact, one of my reasons for upgrading was the supposedly improved NVIDIA drivers in Lucid). VLC, MPlayer and Totem are all choppy playing .avi's: they play smoothly for several seconds, then start skipping (audio and visual, separately), though VLC does so less violently than the others. Similar problems, though slightly less severe, with watching flash movies in chromium.
Streamed videos on various Web sites are slow and choppy for me. The problem seems to be a cross-browser issue, today I did an informal test of various sites I frequently use on both Mozilla Firefox and Chrome. The results of my informal test are below, and as you can see they are mostly the same for both Firefox and Chrome.
Google Chrome- You tube-- no problems once video loads, but loading is slow Daily show-- very slow loading, sound ok, video extremely slow, choppy, unwatchable ESPN--slow to load, sound ok, picture is very slow, choppy eHOW--slow to load, sound ok, picture is very slow, choppy
Mozilla Firefox You tube-- no problems but sometimes slow loading Daily show-- a little slow loading but sound and picture ok ESPN--sound ok but picture very choppy eHOW--slow to load, sound ok, picture is very slow, choppy
I just upgraded to Ubuntu Maverick v 10.10 and loving it. However, I have encountered a problem with playing any type of video whether it be Xvid, AVI, h264, MKV or AAC. I have tried many players from smplayer, mplayer, kmplayer, vlc, etc. but I am still having the problems. I have read some posts on here and I've disabled compiz, tried the X11 tweak and updated my Nvidia drivers. I don't know if I am missing some type of codec or restricted plugin because I have ample space and resources are readily available while playing the video.
I am using ubuntu version Ubuntu 8.04 , it is observed that the video quality is poor as compared to windows os i am not sure it is driver problem or something different, below are detail of my system
I have a HP Compaq nx9010 laptop with 1 gig of memory and 128mb being dedicated to video memory. The graphics chip is ATI Radeon IGP 345M.
I can only set my resolution to 1024 X768. If I try to change it to any other size or try to play any games, the video has millions of jerky horizontal lines going through it. If I hookup an external monitor the video works just fine. Being new to linux and even newer to installing on it laptops, can anyone tell me what if any thing can be done to correct this. I am running Ubuntu 10.4 LTS.
currently using nvidia accelerated graphics driver (version 185) and a nvidia 8800gt. cpu is an intel c2d e6600, so it's quite a fast pc. video playback is extremely choppy to the point of being unwatchable. it affects all applications that i have tried, such as vlc, movie player and flash videos in mozilla firefox. videos on videos seem slow but playable, but when i try to watch them in full screen there's a drop to about 5fps. cpu usage reaches 100%. scrolling is also slow on large webpages. disabling compiz makes no visible difference.
before i installed nvidia's driver, videos played perfectly. videos play fine in windows xp. it seems as if nvidia's driver is using the cpu to 'process' videos, instead of the graphics card. other than that, ubuntu 9.10 is lightning fast... so what's going on here? i have resolved one issue, that is flash player's performance in firefox. followed instructions [here] and videos is now smooth in full screen. other videos, however, are still stuttering and spiking cpu usage. this must be a widespread issue, but the lack of information on the web shows otherwise.
I switched from XP to Ubuntu a few days ago and I'm having a hard time getting flash to work properly in firefox. I can play videos and music in a non-flash format just fine, but flash videos play without sound and really choppily.
I have a ASRock ION 330 with 512 Mbyte shared graphics memory. I use the 256.44 closed source nvidia drivers and have a Xinerama display consisting of one Asus 1440x900 monitor and one video projector with displaysize of 1280x720. Display: 1440x900 + 1280x720 in Xinerama
I have tried with and without desktop effects enabled, and I have followed the http://tombuntu.com/index.php/2009/0...thout-tearing/ guide to manually set the refresh rate to 60 Hz. The sync to Vblank option is checked, both in CCSM and nvidia-settings under X Server Xvideo Settings and under OpenGL Settings, to no avail.
The files I play are MPEG-2 Transport Stream in 720p. Some are and some are not in Matroska containers. I use SMplayer with vdpau enabled. I've made a comparison of Windows Vista and Ubuntu 10.04 below:[URL].. It's not entirely clear from the video, but the end scroller is choppy on Ubuntu and relatively smooth in Windows Vista.
This setup is to be run in a public cinema, and the chopping and tearing is a complete showstopper. It would be a nice showcase to have Ubuntu in the wild like this, but it can't be used if these issues are not resolved.
I have ubuntu 10.04 on an acer aspire with the Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller. According to glxinfo | grep direct, direct rendering is enabled. I'm trying to watch some anime films in .mkv format. I have tried vlc and the stock ubuntu player. The video is choppy with lag between audio and video. How I can diagnose the problem?
I've some videos with poor quality.It has pixelation and such problems.Can somebody suggest me some filters to be used with avidemux for correcting the pixelation and maybe deblocking it
I have a 500MB video that is 720x400. I want to half the size of the video while retaining the same relative quality.My main goal is to half the filesize of the video, but to do that and keep the same relative quality I will have to also make the resolution smaller.I can't seem to find a way to do this.I would preferer to use ffmpeg, but any solution would be good at this point. I would really like to be able to do this from the command line, but if there is a gui program that will also give me the command line it uses, that's great too.Does any one know of a way to half the file size of a video while maintaining the same relative quality?
When I watch movies on Ubuntu I noticed that quality of reproduction is not good as in Windows. All movies seems to have some sort of contrast problem which I don't know how to fix. This problem is not present in Windows (XP/7) and stand-alone DVD players play them also correctly.
Here are images (AVI, DivX format)
Windows version: http://i52.tinypic.com/125hlis.png Linux version: http://i56.tinypic.com/tz53t.png
Also here is MKV format which is noticeably even sharper in Windows:
Windows version: http://i53.tinypic.com/2lmqxqe.png Linux version: http://i53.tinypic.com/15gfmlt.png
Note: I didn't wanted to include them in post since they are quite big and I didn't want to do JPG compress since they might lose quality. Try not to resize them.
On Ubuntu I installed some 'extra' codecs (might be proprietary) via Software center. I use standard movie player that comes with 10.10, but for MKV I use VLC since mkv don't run in standard movie player. On Windows I use k-lite codec pack and GOM player. My guess is that Windows solve those sharpness and contrast issues by using some playback filters (possibly contained in k-lite codec pack) that are unavailable in Ubuntu. I installed proprietary video driver for ATI RADEON 2600.
I hooked up my laptop via monitor cable to the L.C.D. T.V. and ran a patch I found on Ubuntu forums because it wasn't showing up on the T.V. After that it asked me what screen resolution I wanted I entered it and then the screen worked! However, now when I play movies on either the T.V as a monitor or just on the laptop itself it comes out with bad video quality now. It sucks because that was the purpose of hooking up my T.V. as the monitor was to watch movies and videos I have downloaded.
does anyone know of any FOSS program I can use to convert HD X.264 MKV video files to AVI or WMV without loss of quality. I wish to stream these videos from my linux box (yes u can do that via ushare)to my xbox 360 but unfortunaly it wont play MKV files.
I recently installed openSUSE on a new Toshiba and i'm getting very choppy video while watching videos on ....., justin.tv, etc. The video is fine as long as I don't full screen. However, when I try to fullscreen a stream on justin.tv or a ..... video, it instantly becomes choppy and video is extremely delayed in relation to the sound. The sound still continues at it's regular pace, however the video lags behind and is just choppy in general.Also, not sure if this helps, but i'm running an i3 2310M.
having not experienced the issues with jaunty and intel display cards, i can't say whether this is a real problem or not. from what i can tell, mtrr is not a problem.
on my new dell mini 10v w/ intel 945gme and a fresh install of karmic unr, video playback performance is only so-so.
most videos-style flash video is decent. local h.264 playback from .m4v and .mov containers is flawless. but streaming flash video originating as h.264 is dismally choppy - this includes vimeo and hulu-quality streaming video.
when i play streaming video in any browser (tried firefox, chrome, opera, and midori), the playback is severely and unwatchably choppy. sometimes it'll be ok for a few seconds and then devolve into choppiness, but usually it's just choppy right off the bat. the audio is just fine, by the way.the odd thing is, videos works just fine, but only if i stick to 360p. anything higher yields the same results. downloaded videos work just fine as well. i've noticed this on vevo.com, cracked.com, and southparkstudios.com. (my age is showing! ) i just tested it on an html5 video from the html5 site and that worked just fine, as well, so i think this is a flash-specific problem.
right now i'm using xubuntu maverick, but i've used both lucid and maverick of xubuntu and ubuntu netbook remix (all 32-bit). i'm using a lenovo ideapad s10-2 (a netbook), and the video card is intel gma 950. i can get more specific if necessary. i've tried both the open source and non-free versions of flash (latest versions, of course) with no difference. i even tried uninstalling flash and using chrome's built-in flash plugin, also with no difference.
I spent about a half hour wrestling with different website tutorials about how to convert a file with ffmpeg and figuring out how to get all the video quality options right. Then I discovered you can just use the -sameq option and it figures it all out for you if you don't want to change the vid quality but just want it in another format. Thought I'd leave this on the site in case anyone else finds himself in the same boat.
I'm having video issues with my graphic card while using Ubuntu 10.04 LTS 32 bits. When I'm watching video (Either on ....., or a dvd or whatever) There are horizontal lines cutting the video, like when there's very fast movement it doesn't render the video smoothly and so I get to see like vertical divisions, I don't know how to explain it exactly. I have a driver installed, one that installed automatically when I turned normal effects on, but I don't even know which one it is, I'm very new to this.
I'm generally non-techy, but was able to do the install of Lucid on my iBookg4 ppc, and use terminal to cut/paste the fix for my airport extreme card off the ubuntu wiki. my current vexing problem is this: ALL video playback (mp4, .mov, swirly display thing when musicplayer is going, etc) is choppy looking. not pixilated, but kind of messily choppy & grated looking. I've searched all the forums & wikis ('natch) and cant find anything that describes this exact problem. is there a fix that dosen't involve confusing command line judo? something that wont require too much hand-holding? (I am def one of, "the rest of us" that ubuntu is for...)
