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
I am currently trying to start doing some screen casting and having a problem with audio recording in gtk-recordmydesktop. The problem is that I need to record both; my computers audio card output, and my mic input at the same time. As of now I am able to record one or the other.
I'm using recordmydesktop for screencasts and currently use pavucontrol to select the monitor as the input source, as shown in many guides across the Internet, but I can't find anything on how to do it from the command line. How can I select a monitor as the audio input source for recordmydesktop from the command line?
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.
I want to record some streaming internet radio talk shows and music performances on NPR, and I'm wondering what my options are in Ubuntu. I'm looking for something that can output high quality lossless files in several formats, hopefully including mp3 and ogg.
I'm looking for configuring a Ubuntu box, we need to capture alsa output into ffmpeg with jack or OSS but not pulseaudio, as that tends to glitch badly. We have things working, but we are sort of hacking around in the dark, we play music, but as we aren't linux audio experts ourselves.
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.
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.
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.
I'm using openSUSE 11.2 KDE on a Fujitsu-Siemens Amilo Pi 1536 laptop. My problem is that my microphone (I'm attempting to use a 3.5mm headset) doesn't work. Audio playback however does work through the built-in speakers and headphones.
I have gone through the SDB:AudioTroubleshooting - openSUSE as suggested by oldcpu on the Welcome to multimedia sub-area sticky.
I have tested audio recording with
Code: arecord -vv -fdat foo.wav resulting in a silent recording. The vumeter showed 0% during the recording.
Here is my url produced by the alsa-info script:[URL]
I'm having here annoying "problem" with my webcamera. Everytime I want to use it as a microphone it needs to be switched manually in sound settings menu. It's not a big deal but I would really rather let it be switched automatically like plug and play or something like that.
I am running Ubuntu 9.10 (Karmic Koala) on a five year old desktop computer with no problems what-so-ever until that is when i try to use aMSN. The aMSN program is great and problems only arise when i try to configure the audio and webcam. When i open up Preferences -> Edit audio and video settings and try to configure the audio and webcam everything just freezes solid and the only way i can un-freeze the computer is to disconnect the plug from the power connection.
On other occasions when i have again attempted to configure the audio and webcam the whole aMSN program just vanishes off the screen altogether? I have a Logitech QuickCam 8.1.1
I want to listen to this audio file: [URL] but my real player 126.96.36.19928 gold desn play it, it says that there is a codec 28_8 missing, I go to relaplayer page, download the last release available for linux systems, but the message is the same : audio codec missing and doesn't play the audio.
I havev tried to play the audio with smplayer (not luck), vlc can play the audio but the pause button doesn't work so I have to listen the entire audio all the time I stop it playing. Is there any audio player capable od reproducing in the proper way this audio in ubuntu? No one of my video players totem, smplayer, realplayer or vlc are capable of playing this video: [URL]
As an arranger of collegiate a cappella music, I often times need to listen to a song as I'm playing with a midi sequencer or some arranging software. On Ubuntu, since Gutsy, I've often run into the same problem from distribution to distribution:
Midi and audio won't work at the same time. If I have an audio file open on VLC or FireFox, I can't play Midi sequences on my arrangement. If I'm arranging and listening to Midi notes, I can't play music. Note that it's incredibly inconvenient to constantly close one so I can play the other to finish arrangements.
I'm thinking of installing openSUSE-11.1 Gnome on a Fujitsu-Siemens Amilo 7400M laptop because the wireless in Gnome is much more user friendly than KDE3/KDE4 in openSUSE-11.1. The idea is to give this laptop to my 84-year old mother and things need to 'just work' for her (she currently has a desktop running openSUSE-11.1 KDE3 that uses a WIRED interface to the web).
I refuse to update this laptop to openSUSE-11.2 nor 11.3 (nor other recent distributions) because every kernel update after the 2.6.27 kernel has broken the Intel i855GM graphics drivers for that laptop. There are many bug reports and none have fixed the problem for this Fujitsu-Siemens implementation of the i855GM graphics.
Hence I am looking at Gnome.
I booted the laptop to a Gnome openSUSE-11.1 liveCD and wireless is easy and works great. But audio is very very VERY bad. It is incredibly user unfriendly and it does NOT work well. I assume that is because pulse audio in openSUSE-11.1 was very immature.
I note these updated packages in the openSUSE-11.1 update repository:
So my question is, did the updates to pulse audio (in the openSUSE-11.1 update repository) fix the pulse audio situation? Are there ANY helpful views on this?
Currently my wife is using this laptop with KDE-4.4.4 (and openSUSE-11.1) so I can't just install Gnome and play with it without taking the laptop away from her for a while (note the hard drive is too small for a dual boot of KDE/Gnome).

okay, here are the details: can't play any audio with amarok when desktop effects are enabled because the minute a window is moved, it will distort the audio. even when disabling desktop effects, some applications still cause this. can't play videos videos even with desktop effects disabled because of the same reason.
i just switched from ubuntu and when i ran version 11.04, i had to disable kms to do anything. i tried on opensuse 11.4 and the audio was flawless but the gfx went all to hell.
I was trying to fix my audio, I had it coming out of my headphones and speakers at the same time. I was told to run this script to try to fix the problem but it only made it worse. I've attached screen shots showing that I now have no hardware showing.
I've added this packman repo: Index of /suse/openSUSE_11.4/ and installed all the necessary libraries and tools required as mentioned here using zypper: Restricted formats/11.4 - openSUSE Community Wiki When I try to play any movie in VLC I'm able to hear the audio for some time usually 3-4 mins and then audio totally stops though the video continues to play. A random seek or a seek forward/back also cause similar issue almost immediately. I switched the output module in VLC preference to different settings: default, SDL, Unix OSS, Alsa but the same issue persists. The audio recovers if I just enter the Audio settings menu in VLC preferences and click Save (even without changing anything) but after the same 3-4 mins or by seeking, the audio stops.
I disabled Pulseaudio for my sound card(s) in Yast->Sound, and I even kill the pulseaudio process but it somehow starts itself up again when I change anything in VLC audio preferences or even simply click Save without any changes. I've made sure all the multimedia related packages are installed from the packman repo whenever possible (I still observe there are few packages which do not exist on the packman but the openSUSE 11.4 repo alone eg. phonon-backend-gstreamer, phonon-backend-xine) Here is the rpm query output for the multimedia related libraries:
with my motherboard the onboard back sound jack's audio is VERY quiet, but the front jacks wired into HD audio work fine. (I'm building an htpc, btw.)
I tried for weeks to get it to work, but eventually I just pulled a cheap Dynex DX-SC51 card from another machine and turns out it works, but now I can't use the inputs and headphone jack on the front of the case without going into system>preferences>sound and changing "output" back to "internal analog audio stereo"
Is there any way to activate these two audio devices at the same time?
I am having some issues with getting Ubuntu Studio 10.04 to work correctly on my system. Everything works fine except sound. I have a M-Audio Delta 66 audio interface and my onboard sound is disabled. When I run the command alsaconf I can see the ICE1712 card without issue. However when I run alsamixer the only option it is giving me is my HD sound from my ATI video card. For some reason it seems the ATI card has locked the audio to it with no way to remove it. I have reinstalled the alsa drivers for my card and can only see it through alsaconf. When I tell alsaconf to configure the ICE1712 card it says it configured it properly.When I run the command envy24control it says no ICE1712 cards were found.
Is there an application that anyone knows about that I can use to convert either an .flv or .ogg file that contains both audio and video to just an audio .ogg file (preferably vorbis+theora) without audacity? I'm fairly certain audacity could accomplish this but it seems like overkill for what I'm trying to do and the computer I'm trying to use does not run it so well.
::EDIT:: I should also mention that I've tried looking on google. I did find downloadhelper extension for firefox which uses ffmpeg to convert the files but I don't see any obvious way to strip the video.
Running 10.4 Luci RC 64-bit desktop and when attempting to run Applications > Sound & video > Sound recorder, I receive the following error message:
Your audio capture settings are invalid. Please correct them with the "Sound Preferences" under the System-Preferences menu. When I do go to System > Preferences > Input, there is only 1 device - "Internal Audio Analog Stereo" with no options for modification.My laptop does have an internal microphone but it apparently isn't working as nothing was recorded when I ran a Skype test call. This is the reason why I attempted to record something to check the mic.
I have this file:Code:vid-gd-19940626-peggy.rmI would like to extract the audio and copy to a file to burn on a CD.'pitivi' will load the file and show the audio timeline. But I can not find a save or copy button.'vlc' will play the file but I can not find how to seperate/save the audio.I found a 'ffmpeg' that is suppose to read whatever is being sent to your speakers.Code:ffmpeg -f oss -i /dev/dsp -f video4linux2 out.wavThis produce a file that 'mplayer', 'vlc', 'audacity' will load but it is empty of useful data. Black screen only.This is the second week I have worked on this. Either I'm googling for the wrong words or what I'm reading, I don't understand.
I have 9.04 and I recently "got" a 13.2GB 1080p HD movie. When I try to play it, it's choppy and mosaic like. The audio plays fine, but the video jumps and I can't get a clean picture except for maybe 15% of the time. I have to hold down the spacebar so it plays and pauses very quickly for the video to even proceed. I've updates VLC and Movie Player and I've downloaded many codecs and I can't seem to fix it.EDIT: I can play it in Movie Player without the pixel/mosaic-like effect, but it too is extremely choppy.
This plays fine in VLC, and there's a "Record" button there but I'm never prompted to save the recording anywhere. I wandered through preferences but didn't see any default capture directory fields.Where/how do I capture the stream for playback later? The docs that I've stumbled across so far are pretty outdated (but I'm still googling).
