Ubuntu Multimedia :: Video Devices Order Changes On Reboot?
Mar 12, 2010
I'm having a problem with video capture devices. I have a cheap analog capture card (encore) and a webcam.Not sure exactly why, they are mapped as /dev/video0 and /dev/video1 in diferent orders randomly as far as i can see.So, sometimes i reboot having webcam as /dev/video0 and capture card as /dev/video1. But then i reboot later, or next day, and they swap.Then, i have to change config for other programs over and over again. For example, i use tvtime to watch live tv, and i have to edit the config xml files almost everyday... Can i force devices to be always mapped the same way?Can i at least add some kind of alias to use instead of device numbers?
I'm about to go buy a video capture card this week and was wondering if there's one that's easy to setup in Ubuntu or (ideally) has some official open source drivers available. I'm planning on recording videogame footage and the like from my consoles to edit on kdenlive and upload it to ..... (why? Cuz it can be done. =P). So I'm wondering if anyone has any recommendation before I order one. I'm only interested in SD resolution for the time being.
Ubuntu 10.10, fairly fresh install. The order of the icons in the system tray changes each time I reboot. It's worked fine since install a few weeks ago until today when I booted and the wireless wouldn't connect. I rebooted and they came up in a different order so I rebooted again and the order changed yet again. Maybe I should just keep rebooting until I find an order I'm happy with then never switch my machine off.I've attached a printscreen to show what I mean.
ok i have been in Ubuntu for almost a year now and i have a problem i am trying to get worked around or fixed I have searched thousands of times and thousands of sites for the answer it dosen't seem to be really known or talked about yet i have xbox controllers and when i plug them in while the computer is on lsusb reads them but i canto use them on any thing but if i reboot they are recognised by the programs this also goes for my ekey small usb midi keyboard is there a way to get thease devices to recognize while the computer is on couse i hate having to reboot just to play an emulator or somthing or to play with my midi keyboard in lmms
I just loaded 10.10 on an Acer Aspire One D255. When I installed Ubuntu, network manager loaded and I was able to use both the wired and wireless cards. After I used update manager, the kernel was upgraded, and I also added some wireless applications (RutilT WLAN Manager, SWScanner, and WiFi Radar). Upon reboot, the network manager doesn't work, and it cannot find any of the devices.
I have a home server running Debian Wheezy ( 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u6 x86_64 GNU/Linux). I have a Realtek RTL8111/8168B NIC and an Intel 82574L. I saw while searching Google that both cards have this issue. I'm currently using the Realtek card for LAN connectivity. If I try to tranfer large files via SAMBA or have any kind of load on the NIC, my system freezes and requires a reboot in order to restore connectivity. The error message from kern.log is:
Nov 26 02:41:53 golgotha kernel: [ 5178.413329] AMD-Vi: Event logged [IO_PAGE_FAULT device=0a:00.0 domain=0x0021 address=0x0000000000003000 flags=0x0050] Nov 26 02:42:04 golgotha kernel: [ 5188.800088] ------------[ cut here ]------------ Nov 26 02:42:04 golgotha kernel: [ 5188.800100] WARNING: at /build/linux-Tvajqd/linux-3.2.68/net/sched/sch_generic.c:256 dev_watchdog+0xf2/0x151()
[code]....
Everything runs fine until I try to do a large file tranfer or have multiple users connected.
I've searched about various recommended build orders for audio and video components. Below is what I'm currently using. My original intention for the list was to provide good audio and video support via MPlayer, but recently I've also been playing around with adding voice and video support to Pidgin.
I find that I prefer have both panels located at the screen top. That way I don't have to go to the bottom of the screen for one thing, then back to the top for another. I arranged the panel so the regular top one is on top,then the panel that contains the open applications is underneath.The problem is, when I reboot, the panels lose their order. First, the regular top panel initializes, then the bottom ones starts and pushes the first panel down, which becomes what you see in the picture: I would like to find a way to keep them in the opposite order of what you see in the picture, but every time I reboot they end up in that order.
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.
I have two seperated video clips, that captured same event from two cameras. i would like to create one clip, that will show one on the left side, the second on the right side, and play together.
I want to do is this: choose the order (other than alphabetical) of the files that I burn to a disc.Brasero doesn't allow it K3b doesn't allow it GnomeBaker doesn't allow it Unless I am missing something, I can't figure out any way other than renaming all my files with a single number and/or letter at the beginning of a file name to choose the order of files. This blows my mind it seems like the most "no duh" feature that everyone would need in any Cd burning program. if I am stupid or if the software developers are stupid. (because I really can't see any other options) This is seriously so important (to me), that I will abandon Linux and go back to Windows if I can't do it.
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?
I have installed knoppix 6.0.1 persistent to a usb flash drive. I am currently testing it on my laptop and have successfully installed the graphics driver for nVidia Geforce 7150m driver 180.51 All looks great until i restart and it doesnt work again. when i go to reinstall it, it says its already there, but when i open the nvidia-settings, it doesnt look the same as before. If i reinstall it, it works again, until i restart of course.In case this is important, here is how i installed the driver in root terminal: sudo apt-get install gcc make init 3 cd /home/knoppix/Desktop sh NVIDIA-Linux-x86-180.51-pkg1.run (A series of questions come up asking to compile a kernel, etc.) (install runs) init 5
I am guessing that the new kernel needed for the driver that is installed is not being booted up on when knoppix restarts. I am just unsure as how I can make this kernel accessible at start up or how to start up this kernel again without reinstalling the driver
I just attempted to purge and reinstall ALSA (and all of it's related packages/utils) after disabling the on-board sound in an effort to use only an M-Audio Delta 1010 as the sole sound device. I've also tried to reinstall Envy24, as well as drivers for the ICE1712 chip... Now,I have no sound devices. alsamixer tells me there is such file or directory. When I go to /proc there isn't even an asoundrc file there.
I don't know what to do. I've spent the last 4 hours looking for a fix, and trying all sorts of things, even the comprehensive sound troubleshooting guide on this forum. Nothing. I got absolutely nothing. Everything goes exactly as the guide states, except after rebooting, and trying aplay -l and alsamixer, it says there's nothing installed?I have to have a sound, this machine is a DAW .End result I'm looking for is to use the Delta 1010 as the ONLY sound device.
If I, in VLC, choose a folder with several mp4 or other multimedia format files, it will show em in the playlist in random order, definitively not alphabetical. that didnt use to happen before.
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?
Is there any way to change the Yes/No buttons order on the sistem windows (warning, question etc)? Like, is it possible that the "Yes" button appears in the left and the "No" button appears in the right?
don't get impressed with a vanilla kernel 2.6.37 if the "yes" button isn't in the "right place".
Up until about a week ago using Kubuntu 9.10, the sound on this computer was fine, but now every day when I turn the computer on I have no sound and I get a notification from Phonon saying: The audio playback device NVidia (ALC883) does not work. Falling back to.
If I turn the computer off and then back on, sound is working again. code...
My band play with a backing track running out of my laptop. We have a stereo mix of the backing track running into the PA system, plus another stereo mix of the backing track with a metronome running into headphones worn by our drummer. This means that the laptop is outputting 4 audio channels simultaneously. The catch is, i only have a two channel USB audio device, in addition to the two channel built-in soundcard. The trick i found to accomplishing what i desire within Windows was relatively simple - i used the ASIO4ALL driver, which effectively allowed me to combine the outputs into one "virtual" ASIO audio device which has 4 output channels, which i could then send audio to using my digital audio workstation software (REAPER). Luckily this has worked perfectly every time we've done it on stage, however at rehearsals it has on occasion failed as Windows has encountered errors, etc. Naturally it would be devastating for this to happen on stage, and so i've decided to try Linux out, as it has the reputation of being extremely stable (i've heard stories about machines being switched on for years without crashing).
Now, i've tried for a couple of days to get this to work, messing around with JACK, ALSA, and PortAudio, and using a range of programs such as Qtractor, Ardour, and MusE; however, i've only ever been able to get stereo audio to come out of one device at a time. I do however know that it is possible to do what i want, because i found a little DJ application which allowed me to set a different audio device to be in "headphones", whilst my other audio device outputs the currently playing track.
I'm by no means a proficient Linux user, however if something has to be done through a Terminal, with adequate instructions i'm sure i could do it. What i'm after though really, is a simple and clear guide to accomplishing what i want, which to recap is:
A to simultaneously output audio to two separate audio devices at once from within the same program.
