Ubuntu :: Lag In Screen Recording ?
Jun 15, 2010
Spec:
Ubuntu 10.04 (lucid) 2.6.32-22-generic
ATi Raedon HD 2400 PRO (256mb) Graphics Card
3023 MiB Memory
Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz
Whenever I try running ANY screen recording program, my desktop runs too slow to use. I don't think this is a problem with my hardware capabilities, as I used to be able to record my screen perfectly in Windows, whilst doing multiple other tasks. I've installed the ATi/AMD proprietary FGLRX graphics driver.

I've been using Linux for a good six months now, and I'm loving it. I've recently upgraded from Ubuntu 9.10 to Ubuntu 10.04. When I was using 9.10, I couldn't use ANY screen recording software (Trust me, I tried a lot), as it made my desktop 'lag' so much but I just thought it was a problem with my OS, because when I was running Windows Seven I could record my desktop perfectly in HD, whilst running a lot of other applications.
My computer isn't exactly amazing spec, got a dual core 2.20ghz processor, and 256mb ATi Raedon graphic card.
Since recently upgrading to 10.04, I still can't record my desktop due to 'lag'.
Will this be a problem with my hardware? Is my computer just not powerful enough to record my desktop on Ubuntu? Or is another problem which I haven't even thought about?

I know that pressing ctrl+alt+shift+R enables me to record my screen, but I can't merge my voice with it. Is it limited to video recording without audio? If that's true, how can I merge two separate an audio file with video file (Gnome produces *.webm videos by default)

I want to do a screen capture with audio and video. I use Ubuntu 10.04 64-bit.I have now spend about half a day trying various tools, most of which seem to be half finished or abandoned. I have not found any usable docs for any of these.gtk-recordmydesktop and xvidcap will both capture video, but seem unable to capture audio from a microphone. The mic is connected and the sound preferences "input" tab shows the input level jumping up when I speak, so it must be working.
I tried the pulse audio device chooser app to make sure the mic is selected, but the choices for input are DEFAULT and "other", which shows a blank input with no choices.xvidcap multi-frame dialog has dev/dsp pre-selected as the input device, with no other options. It does not work.If I enable audio with gtk-recordmydesktop, it refuses to start and says it cannot open the sound card. There is no apparently no way to do this using the "advanced" dialog which has DEFAULT preselected as the audio input device and no other options. /dev/dsp also fails to start.I spent some time searching google and the forums here, to no avail. So should I give up trying to do this with Linux or is there some obscure method I only need to discover?I prefer xvidcap, since the ogg format output by recordmydesktop seems to be a write-only format.

I've noticed that there are a lot of different programs out there to record your desktop (screencast), and it can be tricky to understand the differences between them, their limitations, and how to use them, so i made a video where i show how to choose between them, what their features are, how to USE them, and how to get the highest quality video from them.
You can find it here: High Quality Screen Casts, Desktop Recording, with Linux

i can't record with my mic anymore. I went to do so in audacity and i only get the noise it hears through the headphones. I am recording a second vocal track. The first track is the music. I looked at the alsamixer and the mic was originally muted and i unmuted. Should line be muted when i am using the mic? I also tried to record with the mic in sound recorder but got nothing there either.

found one other post with this same issue, and the final reply was "I give up"...I got a fresh 9.1 install. I just want to record some audio, but it's only recording on one channel, the left channel.I tried audacity and sound recorder. checked the sound preferences, Hardware set to Analog Stereo Duplex. In audacity Preferences > Devices > Recording, 2 (Stereo) is selected.When recording in audacity the output meter for the left channel shows activity while the right channel looks like it goes up a little bit but doesn't peak like the left channel. I hear fuzziness in the right but all the sound is in the left

I use Kaffeine to record live TV to disk for later playback. I've been putting up with Kaffeine's little foibles for the last little while, but tonight (for the second night in a row) I accidentally closed it and consequently it didn't record anything.
Is there any software I can use to construct a recording schedule which will then not be dependent on me remembering to leave a particular app running? I don't really need this in MPEG4 or anything. The PC stays on 24x7 - I just need it to launch a recording at the correct time.
I've avoided MythTV in all it's incarnations because I want the computer to still function as a normal PC most of the time, and from my admittedly brief trial of MythTV it took over the PC and wouldn't let me open a web browser or a mail client.

I am currently running Ubuntu 9.04 and am looking at upgrading to the upcoming 10.04 LTS release. And have been trying out the new version using the release candidate live CD. The main problem is one that was also evident when 9.04 was originally installed - audio recording and monitoring simply is not working. With 9.04 it took several hours of head-banging and reading HOW-TOs and guides to get to the point where audio input to the sound card played through the speakers and can be recorded by programs such as Audacity.
I've been trying to poke around with 10.04 to get the same results and so far had no success. (Things have changed sufficiently that it does not seem straightforward to simply replicate my 9.04 settings.) This is on 64-bit Ubuntu with a Soundblaster Audigy sound card. It's a little disappointing that we are not yet at the point where this type of basic functionality is working "out of the box" with Ubuntu. Anyone have any tips to setting up 10.04 for audio recording and monitoring?
Although I never did get this working with the live CD, recording worked fine after doing a test installation of Lucid on a spare hard drive. With the live CD the primary line input was not even showing up in alsamixer. With Lucid installed it was no problem to find and crank up the volume on this input. In actuality then, once the installation was actually done it took much less fiddling with this release than it did with 9.04 to get the same results.

I have a problem with my Video recording without any sound. I have looked into the fixes of the 64bit MMPEG upgrades and gone through what steps I can find to fix the problem, although even after going through the re-compile in konsole, as well as then removing it and trying again using K Package Manager, I still have no Audio with my Video when recording in Cheese.Cheese records the video in ogv format, and I have attempted to convert the ogv file to avi format using VLC. I am able to watch the video in both VLC and Dragon Player... but no sound, just video. I have used Cheese to record video's using Ubuntu 8.10 onwards, but my current Kubuntu 10.04.01 (and when I had 10.04) has no sound in the recordings. I have not changed microphone, and I have checked all my connections. I can hear voice in the speakers through the microphone. I am using on board sound, which I have no other issues with. The error message I get tells me that my MMPEG install lacks the AAC Audio Codec.

I have a PVR-150 for recording TV shows.
I can record shows using this command:
Code:
cat /dev/video0 > /mnt/raid/show.mpg
I can watch the show.mpg file while its recoding using VLC, Xine, Mplayer... pretty much any video player.
This is nice because i can pause, rewind, and fast-forward live TV, just like all the commercial DVRs out there.
The problem with this method is returning to "Live TV" mode. When using a commercial DVR, when you are fast-forwarding and reach "Live TV", the player stops fast-forwarding and begins playing the live TV in real-time. When doing the same thing with Xine or VLC, the player simply stops when you reach the EOF.
Is there a player that mimics this? When it get close to the EOF, it switches from Fast-Forward to play?
I used to have MythTV, but it way too bloated for what I want to do.

I want to record conversations and stuff from skype. Now, I want the sound to be as good as possible, so what settings do I choose, what do I mute and all the other volume combinations and settings do I configure etc... To get the best record possible, I need to record from both pc and mic at the same time, but how? As my settings are now I can only record through the mic. So, what do I do? Also, if you could give me a few tips on how I can filter useless background noise.

I am using a microphone to record a sound with gnome recorder. All I get is noise. If I am yelling at the top of my voice, then I get a feeble sound o/p in mid of a lot of noise. I know my mic is alright. I use skype and during a call, the other person can hear me very well. So the problem is not mic. So I shall have to tweak the gnome recorder to get a better o/p.

I use the friendly interactive shell, or fish, as my default shell. I find it much more user-friendly than bash, but lately (as in for the last 2 months, give or take)dding new entries to .config/fish/fish_history and .config/fish/fish_history.tmp. this means when I press up I don't get the last command I typed, but rather the last command from before the bug occurred. I have no idea why this could be and have tried several tricks but none of them have worked. I have made a bug report on launchpad but I was hoping someone here who knows more about shells would know a workaround.The things that I have tried:removing the files to see if it creates a new onemaking sure I have write access to the filesremoving the files and then using touch to create a blank one

Does anyone know of a good time keeping/recording program for Ubuntu that I can use to log hours spent on a project for billing purposes? I'm getting back to doing some web work to make some extra cash, and would love to have a program that does this.

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?

I'm running hauppauge 2250 tuners (2 of them, 4 tuners total).I have the tuners set up and working although when booting up they worked intermitantly until I went through backend setup and restarted the frontend.I solved this by adding a 30 second sleep before backend startup and this seems to have fixed this.I'm still having trouble with burning and ripping dvds.I can play dvds in vlc and mythtv (mythtv since adding the sleep line). but when I try to burn a recording to dvd it fails on growisofs.I get an error 1.I've set the correct region with regionset and I have the dvd codecs.

I just picked up a Microsoft LifeCam Cinema usb webcam. I installed cheese & it takes pictures just fine & records video as long as the mic isn't enabled. However, if go to System-Preferences-Sound and change my input to the mic on the webcam cheese will not record video. When I start recording the window goes black & i have to force quit cheese. I tested the mic with Sound Recorder & it works. There's nothing in the cheese preferences to change & i don't know where else to start looking.
