Ubuntu Multimedia :: Messy Video Playback Also Appears When Use Cheese To Capture Video With My Webcam
Feb 26, 2010
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 trying to record a test video with my built-in webcam, using Cheese. However, after I click "Start recording," the Cheese screen turns black, and Cheese seems to hang. I can click "Stop recording" sometimes -- then I get a split-second video clip. But mostly it just hangs until I force quit.
I'm on an Asus 900HA. I could record video clips on using eeebuntu and Cheese. Is there a setting I need to check?

I'm having a problem using cheese to record video from my webcam. The image is extremely slow to update. Especially when there is lots of movement it sometimes freezes for about a second.
When I use the webcam in Skype it works fine. Does anybody have a clue what might cause this and better yet, how to fix it.

Anybody had any success in getting ffmpeg to work as advertised with video capture from a webcam? I really want to convert the webcam output to VP8 or H264, but apparently ffmpeg can't even capture the webcam with a video4linux device.

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 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?

OpenSUSE seems to have an issue picking up and working with my newer webcam. This webcam does work with linux, it works with Ubuntu 10.04 Lucid and Linux Mint 9 Isadora but openSUSE 11.3 doesnt seem to like it. Information about webcam drivers seems to be missing now, I tried the drivers repo but no luck. Cheese freezes and WXcam comes up with a green screen with no video. This is a gateway product by my understanding but it seems to be linux compatible, especially with the Linux 2.6.34 kernel that both Ubuntu and openSUSE use right now. But for some reason its not quite clicking with openSUSE 11.3

I've been trying for a while now to capture videos with my webcam of my samsung n110 netbook, I am running ubuntu 10.4 and cheese 2.30.1. I can take pictures fine, with effects and everything but when I press "start recording" the webcam seems to turn off or all I see is a black image, then when I press stop recording the camera picture comes back on and then the program freezes. I've tried turning down the resolution, I've tried all the possibilities in gstreamer-properties but nothing helped so far running from terminal didn't give me a clue on what the problem might be either. I would like cheese to work to have photo and video in one program but if someone has a good program to capture video I am willing to try it out.

I have an eeepc, and when I try to record video in cheese, it freezes and maybe records 10 seconds of audio with blank video. I know my computer can handle video, as I can skype with reasonable quality.

Can't seem to figure out how to make usable recordings with my webcam in cheese. when making very short video's like a few seconds...the longest so far was 11 seconds, it will behave just fine and it outputs a playable file with thumbnail and all. But when I try anything longer something seems to go wrong. I can tell first because cheese refuses to display a thumbnail for the resulting video. But also I cannot play it n any player I have (Yes I have pretty much all the codecs) Also when saved as a seperate file Gnome will choke when I try to get it to display properties for it.
I haven't found any errors like this when googling for cheese. Oh my OS is 10.04 and I have the 2.30-something Cheese that's packed for this version (can't get any of the newer cheeses to compile on it so far)

When I play a video in Totem, MPlayer, VLC or whatever, my displayed windows will look transparent in a funny way. Letters are not readable, colours get distorted and images with a black background (colour 0) will display the partial video in it.

I have created several DVDs from my camcorder (sony handycam DCR-HC21 NTSC); however, the recordings are too long. I would like to capture smaller segments of these and load them online to share with family and friends.I would like to know what is the most recommended software for this task. I am running Ubuntu 9.10.I would have done this by using a firewire cable directly attached from the camcorder to my laptop, but my laptop has only USB ports. So I ended up creating DVDs using an stand alone Video Recordable DVD Drive.

How do I capture video from my JVC GR-DF470 MiniDV camera into 10.04 Lucid.PiViTi looks good for an editing app, and I've installed OpenShot as well, but neither have a way of capturing the video from a camera. I used Kino previously in 8.04 Hardy, but it was buggy at best in 9.10 Karmic; I've just installed it in 10.04, but capture keeps stopping after 2 or 3 seconds. I also tried kdenlive, but the audio capture has a lot of 'noise' that is louder than the voices on the tape, and once it finishes capturing video, it doesn't display a 'Save' dialogue as it is supposed to - so that wasn't very successful either.So what can I use to capture video from a MiniDV Camera via Firewire.

I am working in a script I have, to capture video with sound from my capture board, wich is a clone of the pico2000. This script was working in Ubuntu 9.10 untill I reformated my machine and instaled the Ubuntu 10.10, 64 bits. The machine is an AMD Athlon II, 2.6GHz with 3 GBytes of Ram. The former script was:
Code:
#!/bin/bash
clear
SERVICE="mencoder"
MOVIE=$(date +"%H%M")
[Code].....

This is on Karmic Koala 9.10. The video displays fine via guvcview using a Logitech webcam. The trouble is the capturing of the video. With .AVI, I've tried different video formats (MPEG-4, flash, etc.) and none of them will play. The generated .avi file seems to grow with data, but the result is just unplayable -- it just hangs, thinking it's playing. Is there a troubleshooting page or something to figure out what the problem I'm having with guvcviewer is?

I'm using natty. is there any way to get a Pinnacle DVC 101 to capture video from composite source on Ubuntu Natty? it seems that when new releases break functionality they often are never fixed.
I'm also unaware of a simple GUI application to use in order to capture the video. It would need start and stop features.

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 am loving the ubuntu 10.10 interface.my laptop is a toshiba satellite l450 (3gb ram + 2.10ghz amd proc essor. i use a ati radeon hd 3200 graphics card.i have to manually adjust the sound settings if i plug in a headphone or a hdmi cable to suit the necessary output. windows did this automatically.my video quality is very very poor. if i run videos on any browser or watch a movie (avi file) on totem or vlc it is very jumpy and the sound is often out of sync.

I wanted to share this nifty technique I came across for capturing video using the command line. The problem: I have a bunch of old VHS tapes (remember those...?) and need to get them digitized. I have a VCR, and a Dazzle Hollywood DV Bridge which captures video to DV over Firewire (IEEE1394). I first tried using Final Cut Pro, but it wouldn't capture, perhaps because it expects a controllable DV camera, and the Dazzle isn't a DVC device. I then tried my other favorite video editing app, Kdenlive, but it seemed to have the same problem.
I took a quick stab at the other common editors in the repositories (Kino, Openshot, etc.), but no luck with any of them. Then I remembered the dvgrab command, and gave that a shot and it worked, giving me a nice .dv file. However, DV makes pretty big files, which I wanted to compress down to something more manageable. Since I was going to be digitizing hours and hours of tapes, it would be great if I could compress while capturing. A little more googling and I had the answer - you can pipe dvgrab directly into ffmpeg! Here's the command:
Code:
dvgrab -format dv1 - | ffmpeg -f dv -i - -b 2000k -ab 512k -y output.mov
the first part starts the capture, in DV1 format, and outputs it to a pipe file. usually you give dvgrab a filename, like
Code:
dvgrab -format dv1 capture.dv
the second part does the encoding:
-f dv: use DV format
-i -: input from the pipe
-b 2000k: video encoding bitrate of 2000k/sec, high quality
-ab 512k: audio encoding bitrate
-y: overwrite file if it exists
I didn't set the codec explicitly, for Quicktime it defaults to MPEG4. This worked great, capturing a 2-hour tape into a high-quality quicktime around 2GB. But I also wanted to be able to view the capture while it was going. Since I left the field monitors and audio splitters at the office, I had to figure out how to do this in software. Turns out that the "tee" command does exactly what I needed - the shell never ceases to amaze! Here's the full command:
Code:
dvgrab -format dv1 - | tee >(ffmpeg -f dv -i - -b 2000k -ab 512k output.mov) >(playdv --disable-audio --no-mmap)
tee uses the
Code:
>(command)
syntax to pipe simultaneously to multiple processes. The only thing that didn't work was audio playback, which was choppy and introduced errors in the capture file. I think a little tweaking with the capture rates could fix that.

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.

I've installed Ubuntu 9.10 and the prime reason for giving it a go is due to the media center capability with apps such as Moovida and LinuxMce.
Unfortunately during video playback [either divx or flash] there appears to be a random line or lines which flickers on the screen when the video is in fullscreen mode.
I'm using an ATI x1900 video card and have tried using both Tote and VLC, and I have also tried installing the fglrx.
But, both with and without flgrx installed, under the section 'Device' in xorg.conf it says that the driver is 'vesa'.
I don't know how to disable the default ATI driver to enable fglrx, or whether I am going off on completely the wrong tanget and should be looking at something else.
Or is there better support for my type of card in Ubuntu 10 as I don't want to go back to Ubuntu 8 which is the last supported version of the os that ATI developed a driver for my card.

I have a 30" LCD with 2560x1600 pixel resolution. I would like to make and play videos at this resolution, but software decode is too slow, and the GPU accelerated decode (VDPAU) maxes out at 2048 pixels. It might be possible to decode 2Kx2K and cut-and-paste and reorganize the rectangles to fill 2560x1600. But someday I plan on getting a 4K screen (4096x2160 pixels) and I would like to support that too. For that it seems two video streams decoded by two GPUs and exactly synchronized would work.

I have two Ubuntus installed. A 10.04 and a 9.04. In 9.04 if I watch a video in Firefox, it works very smoothly and nicely. Using the "top" command, totem-plugin-vi is using the most cpu time at about 16%, and xorg is using about 5%. But in 10.04, totem is using 72% and xorg is using 26%, and it looks really choppy. I think watching DVDs is the same way. I checked "Hardware Drivers" in the System->Administration menu (in 10.04) and it said "No proprietary drivers are in use on this system." I'm guessing maybe I'm using different video drivers on each system, but I don't even know how to check. and here is an excerpt from lspci:
