Ubuntu Multimedia :: Why The Capture Channels Are Enabled
Aug 15, 2010
I am trying to configure my Kubuntu desktop since some time to have Mumble working perfectly... It was running in the past, i re-installed some days ago and now i have a huge problem. Basically, capturing the microphone works and it's sent to Mumble, however everybody also hears my desktop sound. I tried adjusting channels in KMix with no luck. Also i don't understand why the capture channels are enabled and must stay at minimum volume...
I've installed RPMforge and Smart Package Manager.
I had to create my own Centos 5.5 channels to sync yum repos and smart channels.
Here's the Centos 5.5 channel file for Smart:
Just shut Smart PM down, copy this file into /etc/smart/channels, and restart smart.
Smart should then detect the new channels (repos) for Centos 5.5
Update your channels in Smart, and you should then have yum repos and smart channels both in sync, looking at the same set of packages.
Copy this to CentOS-Base.channel, and add it to the /etc/smart/channels directory.
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and
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 [URL] - Video resolution seems to change during video playback [URL] - Channels cannot be found via DVB-S
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:
when I try to scan for any available satellite channels to use in Myth, I cannot find any channels. I have invoked "scan -V -l UNIVERSAL -s 1 -a 0 /usr/share/dvb/dvb-s/Astra-19.2E" with the following result:
Code: scanning /usr/share/dvb/dvb-s/Astra-19.2E using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 12551500 V 22000000 5 >>> tune to: 12551:v:1:22000
i installed Ubuntu 9.10 and it seems i can't have 5.1 sound playing, i've searched a lot but i still haven't found a solution to my problem. tried to change the default channels from 2 to 6, as well as the default-channel-map and much more but still nothing works..
I have installed mythbuntu 10.04 and installed my tv tuner (saa7130). I can play games on composite but cannot scan for tv cannels. how i can scan for channels because he cannot find a single channel (I think this is weird) ?
It doesn't matter if I set the audio to 5.1 or 7.1, the center and LFE are silent. I had the same problem in 9.10 but I could work around by using the alsamixer to set the center to 90%, quit, then set back to 100%. This doesn't work in 10.04 as the controls in the alsamixer can't be changed. Is there any way I can get the center channel working? All I can do at the moment is set the sound properties to 4.0 so that the center channel is automatically redistributed to the other channels, but that isn't a great solution.
I am using ubuntu 10.04.I am trying to get 6 channel audio output.When i open alsamixer it does not show controls for multiple channels. I have seen on articles i read that alsamixer shows controls for multiple channels.how to configure 6 channel audio output on ubuntu 10.04.
KMix 4.6.0 in OpenSUSE 11.4 (x86) doesn't show up channels. It only shows "Internal sound Analog stereo" So I can't set the input/output channels and the headphone channel for my soundcard. The right soundcard drivers are installed (for Creative Sound Blaster Platinum Live Drive). Earlier versions of KMix worked just fine.
I can't get mythtv to play television with my Hauppauge HVR-850 tv card. I was able to view tv in mplayer, so I know that the card is working. The tv signal is broadcast only (no cable). I had to set the card type to DVB DTV capture card (v3.x) to get mythtv-setup to successfully scan. I was able to successfully scan both with a "full scan" and with a channels.conf file that I had generated earlier when tinkering tv in mplayer. Unfortunately, the mythtv frontend failed to play any live tv. It said "Error: MythTV is using all inputs, but there are no active recordings?"
I have recently installed Ubuntu 10.10 and it got really nice interface and is pretty user friendly, but I got an issue directed to sound. I have used Ubuntu 9 last time and had the same problems. So here are my problems: I got Realtek AC'97 ALC655 on-board sound card with 5.1 support and hardware mixing. By reading posts on google and this forums I got an idea it should work OOB but it won't.
The issues: *when I set the sound output to 5.1 + 1 stereo input it makes all the speakers work but act in weirdo way and testing the each speaker confuses me even more, because it's like(test=real sound source):
*the sound quality is crappy, it feels like it is old radio player because it requires some seconds for sound to 'condensate' and play normally with some crackles and other distortions.. And I'd like to also ask what sound system is mainly used in Ubuntu? Is it alsa,pulse or OSS? Since I can't find a way to see it.
i am trying to list radio channels in Tunapie2 and it won't list anything. It will display TV stations, but not radio.
I removed the software and Re-installed it with the same problem. I even removed most files from my .tunapie folder under my home and just left prefs and favorites alone. I did this before re-installing the software.
I have noticed a few threads on getting sound to work properly. I had a problem getting my internal sound card to work on 5.1 channels and investigated the links and information given in the various threads and found that there are slight differences from the references to what I had to do. Firstly, it's a good idea to read through these links first.
I have a tv tuner card thats a couple years old, well since they are phasing out the old analog cable channels with digital ones, my card is not picking them up anymore. Is there any way to get the digital ones without buying a new card?
Get_iplayer worked very well for me under opensuse 11.2. After installing opensuse 11.3 it continued to work very well with the exception of STREAMING live BBC channels. These do not work at all. It seems the "modes" I am and have been using are not recognised. I use gnome and installed codecs using codecs_gnome.ymp for suse 11.3. I have no problem with any of the multimedia applications I use.
I have a new install of Karmic on my system with a flyvideo 3000 tv card installed. My problem is that it doesn't find any radio channels and the input channel is completely wrong. I don't have any sound on gnomeradio and can't find the config files to change the input channel. The only input option available to me is dig1 - can anyone point me in the right direction?
I have already read the Howto for this tv card and changed the device to radio0 in the setup. I have setup tvtime perfectly with sound channel as well as with a 5.1 surround configuration. I am missing my favourite radio channel. and I want to get rid of my windows installations once and for all! Update: I did a system update and some things have changed: the radio tower graphic on gnomeradio is now green (I assume it is getting a signal) but no sound yet.
I'm just not getting anywhere here after 12 - 15 hours of googling last 3 days.I'm linked out, and linked back, almost into a do-loop, just like a boomerang, and still no vids...
I need to use Skype to contact my kids in South Africa. I live in the UK. This is very important for me. Surely there must be a fix by now on 64bit 10.04 to use mic capture or a workaround.
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.
I've no idea what the heck is going on with my TV capture card, i went to the other posts about my Hauppauge Inc. HDPVR-1250 model 1196 but it all didn't work i have the ubuntu-restricted extras installed but mythtv is not picking up the card. i'm running ubuntu karmic.
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 want to capture the video from my sat box using an extra laptop I have and then distribute a live feed on my network so that I can watch tv on my laptop around the house. I want to use an old Dell X300 with a broken screen. It's not too powerful with a 1.2GHz Pentium M and 640MB ram. I was thinking of throwing Zubuntu or something lighter weight on it. I'll use a usb capture card that will support S-video. I am sure there are plenty of those that will be compatible with Linux. What I need to know is what capture software should I use?
Is there any capture software that will transmit over a network as a live feed? Is my laptop even powerful enough to do what I'm asking? This thing had no problem playing back 480p but capturing, encoding, and distributing over a network is another story. Are there any usb capture cards that use hardware encoding? Would installing a lighter weight distro be necessary in order to gt laptop performance boost it needs to handle what I want to do? And what of software to receive the stream? VLC should have no trouble connecting to the stream right? How about SMPlayer?
I have a Ubuntu Server 10.04 box, which i have a Microsoft LifeCame VX-500 webcam connected via USB.
i think Ubuntu has detected my webcam

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:
I recently converted an amd 64 bit WINdows machine to Lucid 64 bit. Everything has gone well. I had numerous issues with Pulseaudio that I removed it. Sound with Alsa has been great, including system theme sounds. I can record via a mike as well. What I cannot do is to capture sounds coming through the sound card. When I record I am getting empty files. The mixer indicates that there are two capture devices. Here is some data on my audio card.

I'm trying to capture my desktop sound (Video too, but that part's working) but nothing I try works. I've tried various programmes, none of them work. I tried various things I read on different websites, and nothing worked. I noticed /dev/dsp was missing, and put it back by a guide, but that made no difference and disappeared again now I rebooted anyway
I have been trying to put together a mythbox for myself. I installed Ubuntu 10.10 and the newest version of the Mythbox backend. My capture card that I am having issues with is a Hauppauge Wintv-HVR-1850 card, I followed the instructions on installation from linuxtv.org and did not get any errors. I tried to set up Mythtv and it didn't get a signal and couldn't find any channels. I would like to know if my card is even working so I tried using xawtv but still could not get a signal from my card.
how I can verify that my card is installed correctly?
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?
