Ubuntu Multimedia :: 11.04 - Online Playback Jumpy And Stutter
May 26, 2011
I like to watch TV shows online. 75% of the shows I watch are on the big sites like Hulu or CBS. But a lot of the shows I catch (normally older shows I never watched during first-run) are hosted with Megevideo or Loombo (moreso Loombo). 10.10 had no issues with playback quality. But since the upgrade to 11.04, online playback from loombo or megevideo like sites are very poor quality, jumpy and stutter. Video from the big sites are ok. I also noticed that playback in Firefox is not watchable on these sites but if I use Google Chrome it's watchable but still bad. I downloaded Flash from Adobe and installed, and so far I know I have all the plugins I need.
Here's what I have running:
Ubuntu 11.04 32bit.
Firefox 4.0.1 (Canonical).
Google Chrome 10.0.648.151.
Flash Plugin (according to about: plugin in Firefox) Shockwave Flash 10.3 r181.

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.

New installation of Suse 11.3, with a new build of the git repository Cinelerra-CV 4.1 from the [URL] web site instructions.Loaded a 5 second mpg file into Cinelerra, and then tried to play it back in both the viewer and the main window. It does decode the video and play it back, however, the playback speed is not smooth. It jumps, in what look like 1 second intervals, and then it gets really slow towards the end of the playback. By jumps, I mean that it is like the speed of playback is on a curve with bumps on each second. Since this is a new installtion of Cinelerra, it could be some settings that are off, as it has been some time since using Cinelerra.For comparison, the same mpg file plays back fine in Kdenlive, although Kdenlive uses a much smaller playback screen...but it is nice and smooth in terms of playback speed. It also plays fine in Banshee.I did take a look at the Cinelerra html manual, and there was a section on system adjustments that you can make...although I would like to find out what is causing it, and if it is a feature of the Cinelerra build?

I previously posted about noob attempts with Google Earth Problems with Google Earth - openSUSE Forums and discovered my setup 3Ghz Intel p4 i386 with RADEON X300(PCIE) and RADEON X300SE as shown in YaST Hardware Information may not be compatible with linux/opensuse. I've attempted some of the suggestions and either I've had difficulties following instructions (noob alert!) or the solution didn't work for another reason. any offers on improving online playback, in particular; should I get a new graphics card, what would be my best option with limited funds (<50) when I want to be able to watch streams online smoothly but not play games/edit video. Efficient rather than powerful?

After upgrading to 10.10, I have been having all sorts of audio problems, mostly with sound skipping like a record. It happens with sounds both streamed from the internet and from my own system. It also seems to affect flash videos, but that might just be the video moving to sync with the sound? The weirdest thing is that if I move the mouse (either the laptop trackpad or the external mouse), it stops doing it, but as soon as I stop moving the mouse, it skips again.

I have a query about Kdenlive, when putting avi. Files with audio files like wma. It chugs hard and doesn't play out a smooth rendition of the two. I only went to Ubuntu because I thought windows movie maker was a joke in regards to its freezes. I have tryed a few other video editing apps but as far as I can see Kdenlive has all the basics I need except the smooth file use. I suppose would be: does my 2gb RAM and 64 AMD 4000+ fit a video editing standard? What is the best video editing software out there on ubuntu?

I have recently begun contributing to the Folding@Home distributed computing project. Due to oversights in the application's design and to process the most advantageous work units, I need to run this command line app through wine. The application is very CPU/RAM intensive, but it does not put much load on the hard drive. It is multi-threaded and uses up to 100% of all 6 cores in my machine. I run it with a "nice" level of 19 with hopes that it won't slow down my normal desktop use.
Here is the problem... when running this setup, my system will frequently freeze for a fraction of a second and then resume. With the more complicated work units, this can happen 1-2 times per minute. During the freeze, the mouse will stop moving, videos stop playing, music pauses, etc. The system is completely unresponsive. However, each instance only lasts for a very short time. Since this happens so often, my productivity is negatively impacted (and it's very annoying).
I previously ran the native Linux version of F@H without this problem, but that was also processing much less complicated calculations. I have tried with wine 1.2.1 and 1.3.5 with the same results. The application does not have problems running on Windows. It has been suggested that the current Linux CPU scheduler is to blame, but is there anything I can do to resolve this now or work around it?

I am using debian squeeze and did an aptitude upgrade yesterday. Today I've found that VLC won't play any video; the files open and the audio plays, but the video is black. The aptitude log is below.
I note that VLC received a security upgrade a few days ago, but my suspicion is that the source of this problem is more likely to be the upgrade of libavcodec52 from version 4:0.5.2.6 -> 5:0.6.1+svn20101128-0.2. I believe this upgrade came from the debian-multimedia stable repo I have enabled.
Does this sound right, and what could I do to fix my VLC playback? This is new territory for me, and I'm slightly surprised that such an upgrade would come from the stable branch of debian-multimedia (although I know this is not an official source).

I want to stream .avi *divx/xvid* (because of the nice compression and quality) online and have all streams accessible through a web based library type thing. Something like Jinzora ( http://en.jinzora.com/ ) is what I am looking for, but it's buggy. I would even be satisfied with a web based library of streams that you click and open with an external program. I have searched a lot for this and the only thing I found that can do this how I want (if it worked right) was jinzora. I don't want to convert to mpeg4 or flv because of size and quality issues.

I installed 10.04 LTS yesterday on a desktop. I have a problem with the mouse, it's very jumpy/not smooth. I can move it across the screen and it will jump up and down and left to right. Jittery I guess you would say. I've googled this and seen several people with the issue but no one has a rock solid solution. Does anyone here have any suggestions? I know it isn't the mouse, I've tried a different one, and it reacts the same on any surface.

Yesterday I fresh installed Ubuntu 10.04 64 bit LTS on my Toshiba Laptop. This is my second time with Ubuntu so bear with me. I got everything working even the webcam but it won't play dvd movies. When I go to the DVD player icon and try to open it...its won't because it doesn't recognize the dvd format.I have searched but only end up trying stuff that didn't work for it. I guess what it needs is Codec's.

I upgraded from Ubuntu 10.04 to 10.10.
I could play a particular DVD in totem without any problems immediately before the upgrade. Immediately after the upgrade I could not play that particular DVD. I got the error message below code...

I would like to do an online broadcast through Justin tv (nothing dirty, just me working) but the website isn't picking up on the cam. Is there anything I can do?

I recently upgraded my girlfriend laptop to 9.10 and now, for some odd reason, when she plays DVDs on her laptop (the most recent attempt was the latest Harry Potter movie) the movie would play back fine but the colors for everything were way off. I've re-added the medibuntu software sources to her system and applied all available updates but it didn't help.
This problem did not occur on my own computer when attempting to play the exact same DVD.

Is there any way to make Ubuntu play sound like Windows 7? I mean when i, for example, listen to music in Windows 7 the sound is much clearer and besides that i can use room correction to obtain a better surround feeling, but when i listen to music in Ubuntu the sound is not very clear and it sounds like stereo even though the sound is played back through all the speakers (the bass is also a little bit to high).
So far i've tried installing the alsa driver and modifying the output levels of each channel, but didn't quite have the same result as the room correction feature in Windows, and the sound wasn't any clearer either. Note: I have an onboard Realtek soundcard and Logitech x530 speakers

I've been running into issues with VLC crashing now and again, particularly when seeking through the current item using the bar (as opposed to Ctrl-Right Arrow/Left Arrow); it may have happened in a few other spots, but that's usually when I'm not at my keyboard. All files are stored locally on my HD, mostly .avi video. For the most part, when I'm using VLC, I've got Firefox and maybe a Nautilus window running as well. CPU use, Memory use, and System load stay pretty well down (and I've never managed to get my swap usage above 120MiB of the 1.2GiB on the Swap partition).
I've tried removing and reinstalling VLC, no dice; about screen lists Ver 1.0.2 Goldeneye. A side effect of this is that, until I restart the system, the screen is unable to be put to sleep at it's timeout; in the notification bar of the top panel, an icon appears and (if the mouse is left there) a little box will appear with text as follows:
Session active, not inhibited, screen idle.
If you can see this text, your display server is broken and you should notify your distributor.
Please see [URL] for more information.
The URL there listed doesn't have any information that seems to be useful, but, I'd presume that VLC does something to prevent the screen turning off while it's playing (a situation where most folks aren't going to be typing or mousing around), which is undone when VLC ends cleanly (and re-opening, then exiting doesn't fix it).

On almost each mp3 file I try to play, VLC will "lag" during the first seconds. There may be some screeching noise. It looks like vlc can't keep up with the bitrate, and it "skips" some bits.
This doesn't happen with totem (the default media player).

I have tried loading/playing (many different) dvds via VLC / new install of 10.04 (on a laptop through which I had been able to play / burn / rip dvds until I "upgraded")...this is what transpires:
Errors:
Code:
Playback failure:
DVDRead could not open the disc "/dev/sr0".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/sr0'. Check the log for details.
The log reveals:
Code:
dvdread error: DVDRead cannot open source: /dev/sr0
main error: no access module matched "dvd"
main error: open of `dvd:///dev/sr0' failed: no access module matched "dvd".

I have a DVD that I am trying to burn to a disc. What I have is a VIDEO_TS folder. First I burned just that to the disc and it plays fine in my standard DVD player, but when I try to play it back using Ubuntu's Movie Player, it acts like it is going to play for a split second and then goes into stop mode. So, I tried burning the disc again, but this time I added and empty AUDIO_TS folder to it. Still plays fine on the DVD player, but in Movie Player it plays the menu. Only it doesn't show any image, just a '>' symbol that you can move with the mouse.

I'm having some issues with DVD playback. Blu-ray playback is not an issue (at least no more than it is for anyone else using Linux), but when I try to play a DVD the video is garbled and choppy, same as the audio. (see attached picture).
I'm using an Asus BR-04B2T blu-ray reader and an Evgo nVidia gtx460 with nvidia-current drivers.
I removed the blu-ray drive and put a friends dvd drive into my computer to test and see if it's the graphics card or the drive, and the DVD player worked perfectly, flawless playback, so I know it's the drive.
Also the drive is not faulty. Both DVD and Blu-Ray work fine under my windows 7 partition.
I forgot to mention, VLC behaves the same as all other players, as shown in this picture. Also you can almost make out that I'm trying to watch the Simpson's box set my friend got me.

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?
