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.
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 just did a clean install of opensuse 11.3. Pretty much everything is working greatHowever, I tried to record a video of a ..... stream and the sound didn't record while using xvidcap. I'm using all default settings
Would anyone know why this program is no longer working? It starts up fine but as soon as I press record it freezes and I have to terminate the program. I've tried using some different settings but its always with the same result.Does anyone know what might have changed from 11.3 to 11.4 to cause these issues?p.s. Im using the xvidcap package from the packman repository
I'm working on a tutorial using Backtrack 4 Live USB, and I would like to take a screencast of what I'm doing (not just screenshots)So far I have tried these application with limited success:-recordmydesktop -xvidcap -wink -istanbul -vlc -vnc2flvEach time I try the resulting files are generally choppy (at best 1 frame per second) and most don't even end up with a clear view of the screen each time.
I use an online screencasting java applet called screencast-o-matic to record my screen. While recording, I use Compiz's annotation tool. Normally this tool works great, but for some reason while I'm recording, it gets very laggy (drawing is way behind the mouse movements) and less smooth. For example, drawing a circle at a quicker pace not only causes lag, but also makes the circle look more like a polygon with straight lines. While this is happening, my CPU also spikes, with large strains showing up on the java process. I'm running Ubuntu 11.04 with an intel i7 processor. Any ideas as to why annotation lags badly while screencasting, and any ways to fix it,

I am going to cover these four problems in this thread.
1.)Using gtk-recordMyDesktop and xvidcap for recording videos 2.)Saving files in ogv format 3.)Converting ogv to avi or wmv or ? 4.)Uploading ogv video to .....
First, I am using Ubuntu 10.04 and have installed gtk-recordMyDesktop and it works great. Save a nice clear video with good sound. I can play it right from my system and also from my server but I can not upload it to ...... Maybe I should say I can't upload a good video to ...... It uploads OK but it is un-viewable. Just to make sure it wasn't a Ubuntu problem I tried uploading it from Windows 7. Same thing. The next thing I tried was to convert it to another file format and even before I uploaded it, it was un-viewable. (looked the same as when it was uploaded to .....). I tried the conversion in a Windows program called AVS and I also tried doing it with VLC in Ubuntu. VLC just give me a blank file after converting. I don't think the problem is with ..... but with the file itself. To be honest with you I believe the video is high quality but I don't see how I can put them on ...... Has anyone converted ogv files to another format which looks good and can be uploaded to .....? Has anyone uploaded a ogv file to ..... and have it look good? Does anyone know anything I can try to get a good viewable file up to ...... I tried recording a video with xvidcap and get a good video and it looks good on ..... but I can't get the sound to work with it. All I get is clicking in the video. File is in mpeg format.
Here is a youtub video to show you the un-viewable video.[URL]..
I have installed XVidCap Screen Capture. If I record my screen with XVid Cap Screen Capture there is no sound. But if I record with Desktop Recorder there is sound. What is wrong?
I have behringer UCA202 usb card, after plug to usb, it just works , I have only small problem with alsamixer, which still shows by default my integrated HDA Intel, I could switch it by F6 or by alsamixer -c 1no problem, but I expect that default card is now plugged "USB audio", so why alsamixer recognize default audio device as HDA intel and not a USB Audio ?anyone who has two or more sound cards with the same issue ?
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:
Code:
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).
dell inspiron e1505 3.2 gb ram 1.86 ghz intel core duo ati x1400 gfx opensuse 11.4 kde 32 bit.
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.
on my PC I have 2 sound drivers, one from the mainboard (AC97) and one PCI card (ES1969). Because the mainboard sound path did not recording, I installed the PCI sound card and with 11.1, I managed it to play and record all audio data. With 11.2 the PCI sound path plays the system sounds (suse start-up or shut-down sounds) but not the streaming audio data (skype, flash player). But these are played by the mainboard audio instead. The audio-tests from yast->hardware->sound work for both paths. How should I configure the system to redirect the audio streams to the desired (PCI) audio path? The PCI audio is set as primary sound card and is not muted.
I have been using windows operating system for a long time now, but I am not well familiar with linux. Whenever I used to install Windows, I used to install the corresponding audio drivers(in order to listen to the music). The problem I am facing is that I do not know how to install the audio drivers(if they really exist in linux Mint 10 operating system). As a result I am not able to listen to any audio file due to lack of corresponding audio driver programs. make proper configurations settings so that I can listen to audio files in Linux Mint version 10.
Say I have 2 speakers connected to 2 different sound cards. Under Windows, is it possible to have some sort of virtual device that would forward an audio stream to both sound cards? If this can't be easily done under Windows, a solution for Linux is also fine. lternatively, if the 2 speakers are connected to different channels of a sound card, is there any vendor-independent way to duplicate audio to both channels?
i have opensuse 11.3 (64-bit) installed. kde version. my sound card is a creative labs sound blaster x-fi xtreme audio, pcie interface. i am able to listen to cd music without any problems but i am unable to get streaming audio when i visit any internet radio site, videos, yahoo!tv, etc. etc. for instance, when i visit videos, the video part is ok but i cannot hear anything through the speakers. something similar happens when for instance i go to [url] and select any of the music channels. a new window pops up but the music never even starts to stream.
i know for a fact that both sound card and speakers work fine because i've tested them with windows xp. so there must be some setting in opensuse that i've missed. the weird part is that i can listen to music cds without any problems...
I am having some problems getting the onboard sound card on my Intel DP45SG motherboard to work properly under openSuse 11.1. Yast appears to have detected the card as a 82801JI (ICH10 Family) HD Audio Controller, but I cannot get any sound out of the card at all.
I have tried to follow this thread, and have run the alsa-info script, the results of which are posted here. It appears to me that the codec that is listed in the alsa script, which is the IDT 92HD73E1X5, is not the same as that which is listed on Intel's site for this board, which is the IDT 92HD73E codec. Can anyone help me out with regards to getting this going? Additional info below:
I have 2 pc with Asus AMD boards (M4A87TD Evo and M4A88TD-M Evo) running OpenSuse 11.3.on both the front panel audio headset + mic do not work.on one PC I have an other OS also installed, so I know that on this machine the hardware is working.is there a chance to get the frontpanel audio connectors running with the actual openSuse or do I have to wait for the next version with a newer kernel/alsa version?
I'm trying to diagnose a weird problem ... maybe someone has an idea where to start. I'm having a problem with flash videos. The video part displays as if the fast-forward button is being held down; audio sounds correct.
I'm thinking "synchronization error" (duh!) but I'm not sure how to start to diagnose the issue. I'm running OpenSUSE 11.4 x64, and the problem shows up in both chrome and opera.
I am trying to set Empathy up and it takes my account on google talk so i can chat. But when I try to initiate an audio call it falls into an error: "Can't establish audio stream. There was a failure in the call engine. Technical details: Could not sync the state of the new nicesrc with its parent."
I am having difficulty with playing back movie dvd's and audio cd's. I recieve this error from trying to playback X-Men3 in vlc. Playback failure:DVDRead could not open the disk "/dev/sr0".Your input can't be opened:VLC is unable to open the MRL 'dvd:///dev/sr0'. Check the log for details. I have libdvdcss and w32codec-all... mplayer, smplayer, vlc, xine, xine plugins...I can explore the dvd in konqueror and the vob files are reconized as files to be played. However If i click to play nothing will open/happen.
I recently installed OpenSuse 11.1 (i586) on a new laptop (HP 6710b) all has been going well, until I tried to burn audio CDs with K3B using .wav files in a directory in the format 01.wav 02.wav 03.wav etc. To burn the audio CDs I have been running K3B as root to avoid any potential permission issues. I now have a stack of cd 'coasters' with only one lucky success using the command line, which when the exact command was repeated failed again. I have successfully burnt 2 data DVDs using K3B, one as root the second as user, both without problem - so maybe it is not a permissions problem?
I am using K3b 1.0.5 in KDE 4.1.3. (it runs under KDE3) I have not been able to run k3bsetup � it is not part of the installation. However permissions appear correctly set-up � I also added the appropriate users to the group �disk�.
/dev/cdrom lrw-rw----root disk (just points to /dev/sr0) /dev/sr0 -rw-rw---- root disk /usr/bin/cdrecord lrwxr-xr-x root root (just points to /usr/bin/wodim) /usr/bin/wodim-rwxr-xr-xroot root
K3b uses the executables in /usr/bin/x11/ which are just the same. I have not put suid on anything. I tried running cdrecord as a user, however the burn failed.I checked the .wav files and they play fine in kaffeine. I am using the same brand of blank CDs as the DVDs.I have not had the occasion to try a data CD � I've run out of blank disks for the moment.
K3b detects my DVD/CD burner as:
The system device is /dev/sr0 interfaceGeneric SCSI Vendor HL-DT-ST DescriptionDVDRAM GSA-T40L FirmwareKC07
I tried burning audio CDs in both TAO and DAO mode, neither with success.
im a little familiar with opensuse..but when i formatted my pc after the installation of opensuse i realized i missed all the audio and video codecs...now i cant even listen to mp3s let alone watching videos.i remember there was a forum post explaining how to install all the audio and video -well mostly- codecs..could you explain how i can install audio and video codecs?
I have no Pulse Audio libraries anymore...not sure how they got deleted. Sound is working fine though....I wasn't using Pulse to begin with, but don't understand what happened to them....think they got deleted in going to KDE 4.4.1 rel 228 today. Should I have those libraries installed for any reason? If so, what should I install?
PS: If I go to Yast, under multimedia, I know longer see Pulse as an option...only hda_snd_intel or whatever
I am looking for a good audio session handler. On ubuntu I have seen Ladish but it is a preview release. Is there a good audio session handler for openSUSE. http://ladish.org/wiki/demovideo
