Ubuntu Multimedia :: Roadblock Streaming Webcam - Wouldn't Refresh Unless Rebooted
Nov 3, 2010
I have an apache server here that i would like to add a webcam to, to stream video to a webpage hosted on said server. Now i hit some trouble using 10.10 with v4l2 not being able to make use of my webcam.
So this is where i stand right now:
I have ubuntu 9.10 Server installed Apache2 (good install, shows default page on networked computers) Static IP of 192.168.1.4 openssh (works fine) Samba sharing /var/www to my windows machine Logitech C120m connected via USB 2.0
I have tryed 2 guides using both webcam-server and VLC, Neither worked however one would show a single frame when i connected to the webpage when i tryed on other ubuntu desktop, but wouldn't refresh unless i rebooted. I tryed the webcam on my other 9.10 computer and it worked fine with cheese (Video0 is there on the server)
The server has pretty much a clean install with nothing on it (yet). I have 3 empty 40GB hard drives, so installing and testing another release of ubuntu.

Just curious if there is any sort of issues with Ubuntu and JBOD assignments. I had my 2 500GB hdd's as JBOD through my mobo BIOS/RAID Config and it didn't like it. It installed just fine and showed the hard drives separately. I really didn't think anything of it so I continued on.After the install completed successfully, and I rebooted the system, it came to a blank screen with a blinking cursor and wouldn't continue on. So I tried restarting a few times, no luck. Finally I was like "okay screw this, going to install with no RAID setup or JBOD setup." (had RAID issues last night. rabble rabble) Removed RAID configurations and BAM started right up..S. Semi-new to Linux/Ubuntu. Know the basics and what not, just not some of the more advanced stuff.Edit: Okay, so I restarted my computer and removed my USB drive (which I had installed Ubuntu from) and it didn't boot. So it was NOT an issue with JBOD. Guess I'll look for a resolution for that, though.

I'm trying to use a Panasonic DVCPro HD camera as a webcam to stream live video from the camera to services like ustream.tv. Currently, the only way I can find to connect the camera to my computer puts the camera into a special pc connect mode (which does not allow recording) and makes the cameras p2 cards detected as drives. Obviously, this doesn't help me do live streaming (I don't even need to record on the camera).I've seen that on Mac OS X a program called camtwist can be used to do what I want, but it would be nice to find an ubuntu/linux solution.

I have been using this thread for a couple of days and just getting exposed to the vast world of ubuntu after succesfully partitoning the hard drive through a live cd. (a copy of linux for dummies book)So naturally after getting adjusted to the new os I started seeking for downloadable media and applications.Started with flashplayer last night and installed after watching some videos.But when I tried the same thing with vlc through the terminal command; sudo apt-get vlc
The video streaming seased because they wouldn't load it stays searching forever! Now ..... doesn't work.I am afraid that by tampering with the command it also affected the flash player file.This is an ethernet connection , 100 mb/s, netgear router.

Has anyone ever streamed video and audio using VLC before? Try as I might, nothing seems to work (get garbled video or lots of buffer underrun messages from VLC server). The videolan website claims that all the documentation on streaming is outdated too, so there's no help there.

I have a USB webcam connected to a server (dmesg output below). It is currently running Ubuntu 10.04.2 LTS server edition. So it has no X, and I don't want to install any. What I am looking for is a command line program to capture video from this webcam and store it. Also, something that can capture just pictures would be nice (but once I have a video file, I know how to get individual pictures from that). A nice plus would be setting this up as a video stream for other computers to stream the video from (to do what they can do with a stream, like view it in real time, capture individual pictures, save it). If setting up a stream makes the capture part easier, I could go for that. This camera works in the cheese GUI program on a desktop. Colors are bad in bright lights, but then, it's a cheap camera.
I prefer the output/stream in a free/libre video format (vp8/webm, ogg/theora, or dirac), but other formats that Linux software exists for (to record and play) can work if the free ones can't be done. Google finds lots of GUI ways to do this (mostly references to cheese). I did find one page that suggests "mencoder". But it doesn't find this webcam. I found a camera stream server called "camserv". It seems to find this camera, but then freezes. When I start camserv, the camera's blue light goes off, but no video is ever delivered from a web page reference. When I stop it, the camera is in an unusable state and has to be unplugged to reset it (so it can be used with "cheese"). So I'm looking for other software.

I have a problem making work a webcam. At the begining, after the instalation of 10.04 in a new laptop, the webcam did not work but with a lsusb I see that the webcam was Webcam 5986:0241 acer. I was not able to config neither use the webcam with any application. After lots of test and forums reading I could not do my webcam to work, and now when I do a lsusb my webcam does not appear.

I have Googled a bunch for this and have found that it may not be possible, but I would love to find out I am wrong since this is the issue keeping me from switching from Windows full time. My school uses an Exchange server hosted by Microsoft and accessible, from Outlook 2007 through Outlook.com via http proxy. We have laptops with MS office 2007 installed and can use the Outlook connector to connect to this server.Is it possible to use an email client in Linux to connect to this server and retain the use of mail and calendar.

Following is the specification of my user environment.
Ubuntu 10.04 64-bit
Acer Aspire 5542
AMD Turion 2 X2 M500 (2.2 GHz, 1MB L2 Cache)
ATI Radeon HD 4200
4GB DDR2 Memory
500 GB HDD 5400 RPM
Sometimes, both on Gnome MPlayer and Movie Player, videos clips won't play. I use mainly MKV file format and quite often, AVI. I have also installed Ubuntu-Restricted-Extras.
The players will literally not play. When I scroll, it goes through the video clip as if I'm fast forwarding when paused, and then it would still be frozen.
I only use Gnome MPlayer and it's been working fine until like two weeks ago, and when it happens it's also the same for the Movie Player. The problem stays there until I reboot my laptop.
It's random but quite often and it's now doing my head in. It would be nice if any of you gents could give me a good solution without getting involved another player, because I really like Gnome MPlayer.

*Open Clementine.
*Exit UI interfaz (Music-->Exit).
*Clementine still running in the background.
*Kill the process e.g throught KSysGuard ( monitor system kde) or htop application.

I just built a home media server. It's using a Gigabyte E350N-USB3 motherboard with the AMD Fusion processor. So far, everything seems to be working fair enough. However, when it comes to video playback via an HDMI cable to my TV, it's unwatchable. It is okay during slow scenes, but any sudden movement or high action scenes and the problem becomes obvious.I don't know how to explain it other than it appears to have a problem refreshing quickly enough. I see horizontal lines across the film. I originally thought it might be due to low quality AVI files, but I just tried a DVD and it did it just the same.
I'm pretty knew to Ubuntu, so I'm not sure if there are some settings I can tweak, or if I am missing some drivers. Any ideas on where to start?

After upgrading from karmic to lucid I can't change a default refresh rate for my crt monitor connected to my laptop (lcd switched off). I know radeon driver is trying to check what's the highest possible rate and sets it around 85, but the screen starts to "shiver". If I manualy change this setting in system settings for the screen to 75, it is ok. But I have to do this after every boot I generated xorg.conf and the appropriate modeline (it shows in the screen settings), and I added it to both monitor and screen section. Nevertheless the refresh rate is set to auto again in system settings and the screen wiggles a bit. How to disable automatic detection and force my own settings?
P.S Here's my xorg.conf:
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
[Code].....

I've got an annoying problem with refresh rates in everything to do with videos. Basically, anything that requires a quicker refresh than using a word processor. This includes flash movies on a website to playing an offline video. In website flash, the video tends to, well flash on occasion. The other sort of thing is pan lines or whatever they're called in videos like a simple .avi movie.
I currently have the nVidia 270.29 drivers installed for my GTS450 card, but this was happening with older versions. My monitor is a Samsung SyncMaster 943 which is detected. The resolution and refresh rates are sort of fixed on auto configuration. What I mean is, is that I can use the drop down menu to change the resolution to a manual option, and then it allows me to select a refresh rate, but only limited to 60 and 75Hz.
This setting will stay as is until I need reboot or restart Ubuntu. Even clicking on Save to X Configuration File is not a keeper. However, here's another problem. Doesn't matter which refresh rate is selected, I still get the above problems. The same resolution and refresh rate yields no problem under Win7 which I've dual-booted with.

I'm trying to enable a non standad vertical refresh rate of my crt in squeeze/gnome under the radeon driver, which does work under lenny and fglrx out of the box without any additional manual configuration. I already tried adding the VertRefresh option to xorg.conf under the Monitor Section, but that didn't worked out so far. One strange thing is that if i look into the Xorg log file i can see a line which sais as if the driver can see the possible refresh rates, but still in gnome i cant set those refresh rates to be active
# /var/log/Xorg.0.log|less
(II) RADEON(0): Ranges: V min: 50 V max: 160 Hz, H min: 30 H max: 85 kHz, PixClock max 180 MHz
These are probably only the rates which my crt can handle, but still im unable to set 1024x768x100Hz because the max i get is 85Hz for that resolution.

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.

Since upgrading to Lucid a few days ago I'm having intermittent problems (90% of the time)with opening OpenOffice files.When I open up a spreadsheet (.ods) in OO, (whether OO was already open or not) my screens go black, then flash on and off for 30 seconds (ish) as if trying to change the refresh rate.Sometimes this results in Gnome crashing and restarting itself. it settles down and is OK. On a few occasions I have had to change terminal and manually restart gdm.
Here's my environment;
Dell Latitude D620
nVidia GeForce Go 7300 (according to hwinfo)
Ubuntu Lucid 32-bit (upgraded from Jaunty)
2 GB RAM
I've got the recommended "NVIDIA accelerated graphics driver (version current)" hardware driver and the NVIDIA X Server Settings applet, which says my NVIDIA driver version is 195.36.24. I'm running dual screens (1440x900 and 1280x1024) using TwinView. After a flicker, here is what I find in the Xorg.0.log;
Code:
(II) Jun 30 12:17:42 NVIDIA(0): Setting mode
(II) Jun 30 12:17:42 NVIDIA(0): "CRT:nvidia-auto-select+1440+0,DFP:nvidia-auto-select+0+124"
(II) Jun 30 12:17:43 NVIDIA(0): Setting mode

Is it possible to have gnome's display settings recognise higher refresh rates than 56hz, as my nvidia is set to 85hz, but gnome display still thinks its 56hz, and I believe this is causing many programs I'm using to refresh at 56hz. Compiz works beautifully after overriding the refresh rate inside it, as it too thought I was using 56hz instead of 85 but many games aswell as CairoDock as jerky, which makes me think it is a refresh issue.
How can I make gnome know I'm using 85hz?

I'm trying to use an external monitor to watch movies on my linux box (kubuntu maverick) but it results always out of sync. TV-out refresh rate is locked as you can see on the image i've attached right here. This is the output of the nvidia-settings query about the variable RefreshRate:
Code:
Attribute 'RefreshRate' (DeepBlue:0.0; display device: CRT-0): 60.02 Hz.
'RefreshRate' is an integer attribute.
'RefreshRate' is a read-only attribute.
'RefreshRate' is display device specific.

I successfully installed darwin streaming server .. I stream Audio through internet well but videos I can stream locally in my network only .. when I am connected to internet outside my network .. it doesn't stream I think their must be ports opened for that .. or any 1 have any ideas .. the audio is streamed on port 8000 .. video is streamed on port 7070 but locally only .. I opened those 2 ports in my router only the audio is working .. also I opened ports 554,7170 disabled the firewall of the router .. is it a problem of ports or something else .

I'm looking for better tweak my current streaming setup to my analog TV. I'm running everything from the S-Video out on my graphics card to the s-video input on my TV so in essence my computer is occupied if i'm watching something streaming from it.I have an digital converter box hooked up to my tv via coax and a upscaling dvd player to it via component video.Is there a way I could run the streaming in the background or get it so it sends a full true signal and converts it much like the digital video?

I'm dual-booting Win7 and Ubuntu Maverick on both a laptop and a desktop, of course using Ubuntu for as much as I can. Now, I've also got a new Sony Bravia TV that is connected to my home network. I've found it so incredibly easy to stream media from my computers to the TV under Win7 and it really bites me because I want it to be like that in Ubuntu too. But it isn't. sources for streaming media from Ubuntu to a network-connected TV?

About a year ago I installed Ubuntu Server 9.10 Karmic on a machine at my work to act as a file/print server and ftp host. I managed this with a lot of googling and reading of forums and it's still all working exactly as it did on day 1!
Now I would like to use the server to stream a local radio station through speakers into the workshop. I have again googled but have not managed to come up with a solution for a server sytem with no GUI...
The radio station streams in a m3u format.

I would like to stream my HD Movie collection over a wireless network to my PS3 and/or Xbox 360.
All my movie files are MP4s and I wondering if it is possible to do this. If possible, I'd like to use the VLC player to do this but its not too important. I really really really do not want to sacrifice any video or sound quality while streaming.
