Software :: Running Xvidcap - For Screen Capture - Audacity - For Audio - Simultaneously

Jan 23, 2011

Im trying to create some screencast videos on Ubuntu. As its a well known fact we dont have a very good screencasting too like Camtasia(only windows) on linux.

After googling extensively I zeroed on Xvidcap for screen capturing and Audacity for audio capture.

According to tutorial [url] first we need to run Xvidcap (do the screen capturing recording first) and then again use Audacity for audio recording .. then mix both video and audio.

I guess this is a pain staking process (running video and audio recording seperately), I thought of running Xvidcap and Audacity simultaneously, if i do this xvicap works perfectly (video capturing happens) but audio capture through audacity does not work.

Note: I even try to run the above tools from seperate terminals/consoles (assuming they are seperate processes)

I even disabled 'audio' in xvidcap and tried to run both at the same time but audacity refuses to work.

I think both the tools are trying to use the same system resources ... and audacity is unable to get hold of the required resources.

Can we run both independently at the same time ?

OpenSUSE Multimedia :: Capture Desktop Screen And Audio?

May 16, 2011

I'm trying to capture my desktop screen and audio , before I used xvidcap but after upgrading my system I can not use it and also recordmydesktop anymore these APPs hanged when I try to use them.Now I try to use recorditnow via ffmpeg recorder interface , it work properly in recording the desktop but it does not record the sound , so I tried to add below options to its command -f alsa -ac 2 -i hw:0,0 but it just record sound at the beginning and just for 1 second. Also when I try to capture my desktop with ffmpeg directly from command line with below command I face with same problem!!! ffmpeg -f x11grab -s 1024X768 -r 30 -i :0.0 -f alsa -ac 2 -i hw:0,0 ~/out.mpg

OpenSUSE :: Xvidcap And Screencast With Audio In General?

Nov 30, 2010

I'm wondering what I am missing. I have a logitec USB webcam with a mic. I use it for Team Speak, and Skype, so I know it works (I literally just placed a test call in skype to confirm...) I am trying to record a screen cast in OpenSUSE 11.3 and KDE4 with audio. Using any application that will do it.

I have tried gtkrecordmydesktop... but when I click on the "advanced" button to setup my audio... nothing happens... so I moved on. (it is supposed to present a window with options for setup... like sound source..)

I tried xvidcap, but I don't know what "device" to point the capture at. When I try to record from /dev/dsp (the default device) I get an error that says it cannot identify the file type. What "device" do I need to point to to get it to use my mic?

I have read about half a dozen forums about the issue, and many of them say that normally it is a mixer problem. I have systematically gone through my mixer item by item adjusting capture settings, mute, and volume levels on each item, then recorded to see if I got sound... and I got nothing. I know the device works, and I can get it to work in some programs (team speak, and skype), but How to I tell xvidcap to use it??? I found my device in the /dev list... it is /dev/snd/by-id/usb-046d_08c9_938E22B5-02 But when I point to that I get the same error.

I am not stuck on any one program to do this but I need to be able to record screen casts with synchronized audio in Linux. I am not afraid of the console or shell scripts... can anyone offer some suggestions... I have a working mic... I just need something that can use it.The best recommendation I've heard (so far) is running VNC and using camstudio in windows... but since my windows box is the same as my linux box... that is a bit difficult.... I really need a real linux solution.

Ubuntu :: Streaming Audio - Capture Outgoing Audio On Windows Computer - Stream It Across Wifi To Netbook

Sep 20, 2010

I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.

Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.

So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.

Fedora :: F12 - Edit Some Audio In Audacity - Cannot Get Any Sound

Jan 4, 2010

I am trying to use FC12 to edit multimedia projects for my work.

Right now I just want to edit some audio in Audacity.

I switched back to Linux after a few years, because it usually is "better" than Windows.

I cannot get any sound. I installed ALSA removed and reinstalled PulseAudio and everything else I could find in a forum, to no avail.

Linux tells me my sound card is: 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

I used to be able to play MP3s but that went away in the process of all this.

Is there one solution I am missing, or do I have to change everything around depending on what I am doing?

I would like to use Linux for this but deadlines might make me go back to the dark side....

Ubuntu :: Convert 3gp Audio Files For Audacity

Jun 21, 2010

I have an android phone. The voice recorder records files in 3gp audio only format. I can play these on my computer with the standard gnome player and with vlc. However, audacity won't open it up. There is an error that says that FFmpeg should import it but it didn't understand the format. I need to edit some of these audio files for use. Is there a way to convert these files to mp3 or flac so I can edit them? Searches turn up w32 ware and some arcane mencoder commands but they have to do with converting video.

Ubuntu :: Recording Audio Streams Using Audacity?

Aug 19, 2010

i am trying to use Audacity to record internally the sound playing on my computer, and im finding the program quite confusing. I have found that by connecting the line out to the line in i am able to record, but the quality is rubbish, it will be a lot smoother recording it internally but I cant find a way of doing this, does anyone know how to record that way or know where i'm going wrong?

General :: Audio - Can't Hear It But Audacity Can Record It

Jul 13, 2010

I've installed a tv card but I can't hear the sound through my built-in CMedia soundcard when I watch tv with TVTime. The tv card's audio output is externally connected to my soundcard's line in input. In the 'Input' tab of the 'Sound Preferences' dialog, I can see the input level meter moving.

Audacity can record the tv sound, and I can hear it when I have the 'pass-through' option enabled, or when I play the recording.

I can play media files without a problem, and I can hear the system sounds.

But for some reason I can't get the tv sound to go through to the soundcard's output.

Obviously I've got the audio configured wrong, but I don't know what to do to fix it.

Ubuntu :: Audacity And QJackctl Refusing To Pick Up Audio?

Aug 1, 2011

I got a mixer today and did everything correctly there and I am trying to put the audio through the microphone input which is fine. But when I try to record through Audacity it's as though the microphone and mixer aren't plugged in. I've played around with the settings in both qJackctl and Audacity only to result worse off than before. Can anybody tell me what I'm doing wrong?

OpenSUSE Multimedia :: Tune Audacity Recording With Pulse Audio?

Jun 18, 2011

I'm trying to capture audio from a stream, NOT from the mic. This is what I'm doing: Start Audacity, push its record button, play a song. It shows that it is recording but when I play back the results, all background noise, conversation, etc, is in the recording as well as the audio from the song. If the mic is unplugged, I cannot record what I hear coming from the sound card (as in what you hear from the sound card is what you get). I got directions on how to do what I want here ( Looking (maybe) for audio mixer for use with Pulse Audio - Page 2 Posts # 4 and 5) but it's not permanent. I got the instructions in post #11 from that same page to make such a change permanent. I tried using the instructions to make the change permanent (I backed up my default.pa just in case something went wrong) and these are the changes I had made:

Code:

### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
#load-module module-alsa-sink

[code]....

Ubuntu Multimedia :: Rear Two Speakers Play Audio Simultaneously

Apr 10, 2011

I have an onboard Realtek HD soundcard which I have 2 2.1 sound systems hooked into. The rear two speakers play audio simultaneously i.e running the terminal sound test "front left" and "front right" come out of both the rear speakers at the same time. I am running Ubuntu Natty Narwhal 11.04 with all of the latest updates. May be unrelated, but also there seems to be a very large amount of lag when playing system sounds. Takes a few seconds after the event has occurred for the associated sound to play.

Ubuntu Multimedia :: Recording With Audacity And Sound Blaster Mp3 / External Usb Audio Card

Jul 18, 2010

I'm trying to record some audio from 4-track cassette tapes using Audacity and a Sound Blaster mp3+ external usb audio card.I'm using Karmic.I have fiddled with levels on the sound card using alsamixer, but the only I way I can detect any sound from the tapes when recording is by turning the levels all the way up in alsamixer, and in doing this, I can faintly make out the audio beneath a large wall of static. If the levels are not maxed out, I only get static when recording in Audacity.

what i want to do is run two commands (nautilus and gedit) from the command line/shell script at the same time. i can obviously do && between them, but this requires the first app to close before moving on to the second one. i want to run both apps at the same time so i can run gedit with some project files open on it, and nautilus to browse those files/other files.

Ubuntu Multimedia :: Audacity / Record In Audacity In 8.10 64 Bit On A Dell Studio 1535?

May 10, 2010

I am trying to record in Audacity in Ubuntu 8.10 64 bit on a Dell Studio 1535 laptop.The problem is not that its not recording, per se.Rather, the problem is its not recording the way that I want it to.

Its recording from the built-in mic, and I want to use the mic jack instead as a line in from a guitar (well, technically, an acoustic-electric resonator, but its close enough to a guitar to call it a guitar).

I have tried using various devices for recording, and changing settings in both the Volume Control and Sound Preferences, but no matter what I do, Audacity still records from my built-in microphones, instead of from the line-in.

OpenSUSE :: Capture Audio Stream In VLC

Fedora :: Analog Audio Capture Not Working?

Mar 9, 2010

I'm trying to get skype going in Fedora 12 KDE x86_64 (fully updated). I did some testing with and without the pulseaudio server installed. With the pulseaudio, I didn't manage at all. I know I got it working before _without_ pulseaudio, but after a yum update the pulseaudio got reinstalled and the mic stopped working. Now I traced this problem down to what I think is wrong: I have a HDA Intel sound card, but 'cat /proc/asound/devices', doesn't show me any analog capture input at all:

cat /proc/asound/devices
2: : timer
3: : sequencer

OpenSUSE Multimedia :: How To Specify Capture Audio Device In VLC

Jun 1, 2011

I need to capture from my webcam. It has a mic too.I can specify video input device as /dev/video0.I specified input audio device as /dev/dsp2 ( OSS device, corresponding to USB Webcam), Now VLC throws an error, "VLC is unable to open the MRL 'alsa:///dev/dsp2'. Check the log for details".Thinking it wants an alsa device, I specify device as /dev/snd/pcmC2D0c. (got it from kinfocenter and dolphin). Now again an error, "VLC is unable to open the MRL 'alsa:///dev/snd/pcmC2D0c'. Check the log for details.".I try with any device, the same error. I have added myself to audio device so that I can read/write to the mentioned devices.I see no way of switching VLC to use OSS. And I see no information (documentation on net) on it's expected device listing for audio.

OpenSUSE Multimedia :: Unable To Capture Audio From Mic?

Jun 5, 2011

I recently installed openSUSE 11.4-64bit on my Gateway desktop, and I can't seem to get my mic work at all. The mic is built into my Microsoft LifeCam Cinema webcam and works fine when I boot into Windows. The mic will not record sound in krecord or lame and doesn't work during Skype sessions.

According to the literature for the device driver my the mic should be supported, and that is evidenced by the fact that the mic shows up as a capture device in in kmix. I have made this mic the master channel under capture devices and I have given it highest preference amongst my capture devices in both the Communications and Accessibility categories of kmix's Settings/Audio Setup.

There was a very similar case solved in January:

How I got my Sound Input working

I've done my best to implement these fixes, but half of it looks like gibberish to me. All I was really able to do was update my alsa software and generate this comprehensive alsa.conf (its long, so I'll wait to post it until asked).

I've had since updating to 11.4, and I gotta say: I've been really impressed so far.

Debian Multimedia :: VLC Stream Capture Audio Out Of Sync

Oct 20, 2015

So I got myself a USB capture card (EasyCap) to use for capturing gaming, digitizing my kids' old VHS movies, etc. It works fine, I've been using VLC to view and record stuff from it, but I've noticed one issue. When recording streams via VLC, even with no other programs running to give VLC as much CPU time as it wants, the audio slowly falls out of sync. I've tried the MP4 (H264/MP3) container and the OGG (Vorbis/Theora) container.

Early on you can't hardly tell, but the further into a movie you get the more out of sync the audio gets, so that by the end of the movie the audio is a good 1-2 seconds off. It's not a set amount either so I can't just split the audio to a separate file then shift it one direction or the other to make up for the difference, because like I said, the offset starts out at nothing and gets progressively larger as the movie goes on. When I select "display locally", the video/audio that is displayed stays in sync, only the video/audio that gets committed to the output file falls out of sync, and it doesn't matter if I play the file with Totem or VLC.
