Ubuntu Multimedia :: Stuttering Video When Running At 50Hz
Aug 22, 2010
I'm seeing regular stuttering in PAL video when running at the default 1920x1080 50Hz but not apparent when I use nvidia-settings to switch output to 60Hz. It's most noticeable when the video pans and you can see the video stutter ever half second or so.
when i play a video (normal and full screen) there are some vertical lines appearing in the video (it actually stutters), this happens in videos and other online video sites as well. i have installed the nvidia software for my graphics card also.
VLC says: "main input error: ES_OUT_SET_(GROUP_)PCR is called too late" when I am playing back most Bluray discs I have tried.
See this bug post for what I am talking about: [URL].... It has to do with playing back h264 video with ALSA.
Possible fixes: 1. Obtain VLC 2.2.2 - see below 2. Fix by Modax here: https://trac.videolan.org/vlc/ticket/10422 - not currently using dmix and not sure how this will relate to HDMI sound 3. Use Pulseaudio - this does not work for me to get HDMI sound and I do not use Pulseaudio as a rule
I have just tried to compile VLC 2.2.2 and the configure script finished properly but early in the build it fails.
With make the error is:
Code: Select alljason@MEDIA:~/vlc-2.2.2$ make -j4 make all-recursive make: Entering directory '/home/jason/vlc-2.2.2' Making all in compat make: Entering directory '/home/jason/vlc-2.2.2/compat' GEN dummy.c make all-am
And with compile the error is:

I have tried installing 3 different versions of libua-dev, 5.1, 5.2 and 5.3. What could be the problem?
With the bugged audio drivers I'm going to replace the computer but it would still be nice to be able to know the solution to compiling VLC 2.2.2.
i've been experiencing an issue with audio playback for certain flash videos that stream from the web. most play smoothly, like the videos at videos. others have this strange background noise that is only present when there is audio (usually on news websites that host their own videos). when there is sound, there is a strange stuttering noise that disappears during the silent pauses.
here's a perfect example: epidemic of tsa criminality: more agents caught stealing cash from luggage, another arrested for assault. the videos video at the top plays just fine. if you scroll down and watch the other video in the small box, you'll hear the stuttering. i have fedora 14 kde, adobe flash player 64 bit preview release 3 and rpm fusion codecs installed. the problem is also present in fedora 14 with gnome, same setup. the problematic videos play without the stuttering in ubuntu.
I've been having a problem with intermittent stuttering in video and audio playback since upgrading to Maverick (it also happened when I briefly installed Lucid). It started out as the odd skip every 20 minutes or so but now it can happen 5 or 6 times in 10 minutes when watching a film. I've tried:
reformatting and clean installing using a half-dozen players installing every codec I could think of (only after the normal ones wouldn't help) diangosing my 3 hard drives (the problem occurs on them all and they're not in a RAID setup) changing then changing back my video drivers disabling pulseaudio and ubuntuone-sync (these were not installed in my previous, working setup) looking at every relevant log file (mplayer, smplayer, demsg...) I know of running ubuntu's testing utilities I'm out of ideas. Going back to Jaunty is the only solution I'm pretty sure will work but it's not exactly ideal. It will be a few months a least before I'm able to install a completely new distro.
This forum has been a wonderful treasure of knowledge. I am stuck up with something thats getting onto my nerves. I have installed lucid and followed the perfect desktop guide.
I have a mkv file (4.6Gigs) 1080p HD with DTS 5.1 audio. when I play the file either of the video or audio gets stuck (mostly video) I tried every possible configs from this forum but in vain. Im using Dell LAT D830 with 2GB RAM 2.2GHz CPU NVIDIA Graphics.
In Karmic's Amarok 2.2, when you pause and then play, the sound usually stutters a few times before it starts playing smoothly. I originally thought this was a pulseaudio issue, as stuttering problems have been reported with pulse, but that wouldn't explain why sound is fine in mplayer, audacious, vlc, dragon player, and virtualbox. Only amarok has this problem. I found the cause of the problem: phonon-backend-xine. These steps will get rid of the stuttering problem:
1. Install phonon-backend-mplayer. You can get it from Rog131's PPA: [URL]
2. In Multimedia and Sound Configuration, which you can reach through amarok's Playback settings, on the Backend tab, click the arrows to move mplayer up above xine.
3. Quit and restart amarok.
There are some tradeoffs for good sound. Amarok seems to have some bugs when the sound backend is not xine, and bookmarks and OSD are broken when this backend is playing the sound. When you quit Amarok, it can't bookmark your place so it doesn't restart from where you last were, and after the track changes once, the OSD when you hover over the tray icon only says "Amarok - No track playing." You have to open Amarok to find that info. Are there any settings I can access for phonon-backend-xine that could fix the stuttering issue? The problems with the mplayer backend are minor compared with xine's bad sound, but I would like nice sound, OSD, and bookmarking.
I'm using currently ubuntu 10.10. Having a nvidia gt220 with the proprietary drivers. I used compiz for a while. It works quite well, with vsync on and so on. But one thing bothers me all the time: In any opengl program (like a game or the unigen benchmarks) or on video playback (no matter if its the default video player, xbmc or what ever) I see some kind of stutter. About every second or so it jumps one frame forward and then two back. Till the next second it plays fluid.
To be able to observe this easily you need a video (or a opengl scene) where the whole screen scrolls in a medium speed but smooth. Than you can observ how it "jumps" every second. If the scrolling is too slow you wont observe it. Now, if I turn composite off this disapears. All play fluid. Ofcourse I get tearing as long as I do not also disable the composite extension in the xorg.conf, but this is another story. Is there a possibility to fix this stuttering with compiz active? Cause I use this pc to watch movies quite often so this would render compiz unusable.
i recently did a clean install of 10.10 to an old box i had so i could mess around with it and learn. however, all audio (and videos too) would stutter and play very quickly (a 1 minute videos video would play in about 45 seconds). so i followed the solution found here: [url]
this fixed the playback problems perfectly, however, i lost the volume control applet in the upper-right of the screen. reinstalling to volume control and then adding the "indicator applet" back to the panel adds a non-functional volume control icon and an additional mail icon.
I've just made the move to openSUSE* and after the installer seemed to bork my xorg.conf because of my Wacom tablet things have been going quite smoothly. My only problem at the moment is that MP3 playback through Exaile, Banshee or Totem stutters and pauses several times per track or more. The only commonality I can see is GStreamer, but nothing is giving me errors to the console.
* I ditched Fedora to get better Monodevelop support after using Redhat 7.3 and 9 followed by FC 3 and 6 then Fedora 7, 8, 9 and 10. The Ubuntu forums seemed to keep giving me occasional answers to questions, but the Suse build service gave me the RPMs, when the requirements matched.
I have some videos on my harddrive. In most of them the sound just stutters for a short while and then they work fine. But others the stuttering seems to go on. I must admit I didn't have the guts to check the whole videos...Its kind of torture to watch a full length music video with stuttering sound... Man...I'm asking so many questions here I'm starting to get ashamed of myself
I have one laptop connected to my tv. It has all the videos on it. ther laptop(actually a netbook) that I have set up to do light browsing on. Both are running ubuntu 9.10. I would to be able to remotely control vlc running on the laptop connected to the tv from the netbook. I have been searching for a while and have found hints that this is possible, but everything either refers to streaming from one machine to another or doesn't give enough examples to figure it out. I have tried enabling the http interface, but I can't access this from another computer.
Would it be possible for a video chat service to work between computers running Ubuntu 10.04/10.10 on the same LAN, but necessarily with an internet connection? Computer #1 wants to video chat with Computer #2 in the next room, part of the same network, but this network has no access to outside internet...
I had an old thinkpad x61s laptop running ubuntu 10.10 with an intel gm965 graphics card. When i checked the monitor today it says the refreshing rate is 50hz and there is no other option available. I vaguely remember it used to be working at 60hz when I was running xp, so I googled and searched the forum for answers but came with no luck. Some people reported a similar problem with their nvidia graphic card and they seems to be able to modify a xorg.conf file to manually solve the issue (sadly I don't know how).
ubuntu lucid 10.04 with the latest update up to june 6, 2010, could not play mp3 files smoothly. it always stutter randomly.i'm using gigabyte amd 780g chipset with realtek high definition audio chipset.
I want to watch a certain video on [url]...., but I get an error message instead. Some videos can be played, so I'm thinking it's a form of restriction, but I can't be sure.I tried using a few proxies, but on some the error message persists and on others the video doesn't load. I'm running Ubuntu 9.10 and Firefox 3.5.8.
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 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?
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...
this happens with both VLC and Totem, when in either of those programs playing a video, if I click on one of the top menus, say View in Totem, the video stays on top of the drop down options. In order to see the options I have to hover over them with the mouse at which point they become momentarily visible. I read a post somewhere where someone had a similar problem and it was solved by reinstalling Compiz, but I've tried uninstalling it entirely, reinstalling it, etc. and none of it works. It doesn't happen with flash videos in firefox, it does happen with visualisations in Totem, and it only started happening since I upgraded to 11.04.
the movie i downloaded plays for only 19 sec and stops saying you will be redirected to microsoft download page. the file is 700 Mb. i installed w32 codecs after searching through many threads but still my vlc doesnt play the file.
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.
My system: Pentium 4 3.6 GHz, 3 Gb DDR ram, GeForce 210 video card, Ubuntu 10.04.
I have previously used Cinelerra-cv (on Karmic) and recently Openshot (on Lucid) with not much trouble. I have been sampling other video editors (Kdenlive, avidemux, kino etc). Now I have my video card crashing whichever I use, mainly when trying to load clips. I have disabled Compiz, uninstalled all video editors and then reinstalled one at a time. I still get early video crashes whichever I try.
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?
Phenom 9500+ quad core, 3GB RAM, Nvidia 8800GT: 260.19.36 driver.Installed the latest Boxee for Linux. Got my remote setup. Everything works except when I open a video it opens in a tiny box in the upper left hand corner of my monitor.Is there any way to get Boxee videos to play full-screen?
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?
