Software :: RecordMyDesktop Output Video Shows *massive* Artifacts Else Plays Too Fast?
Oct 21, 2010
I recently tried out recordMyDesktop (not the GTK+ frontend, just the CLI program, I wanted to Keep It Simple this time ), and found that the videos it records/encodes show massive motion-smearing artifacts when played back. This is without the "--on-the-fly-encoding" option; with it, the video looks fine (i.e. has no artifacts other than the typical ones found in any compressed video), but it plays back too quickly (the time-step between frames is too high, thus making everything go too fast when the video is played back, even though the frame rate is low). Here's a screenshot of the video playing, showing what the artifacts look like (they're nasty!).
I've searched Google and LQ about this problem to no avail: either there were no relevant results, or it was just a post on a different forum asking basically the same question, but with no answer. So apparently this problem is either really rare, or it's something specific to my configuration, and mine alone (highly unlikely).
I've tried different options, such as --quick-subsampling, as well as tweaking the video quality and bitrate settings (--v_quality and --v_bitrate), all of which did nothing to change/get rid of the artifacts.
I've been hunting around for some screen capture software in Ubuntu, for future screencasts and out of the handful I've tried I've gone with gtk-recordmydesktop. After initial problems with recording quality, I have managed to get everything working but have noticed that on playback of any captured video, is played back at a crazy speed, the frame rate is not the issue as it is on the default 15 FPS setting but still the play back is very fast.
I noticed before my tweaking that playback was normal speed, but the quality was garbage, and I found that this was because of Compiz being enabled, and I have to run gtk-recordmydesktop with "Encode on the fly" and "Full shots at every frame" enabled in order for the video playback to not be all cut up, however ever since encoding on the fly has been enabled, this has caused playback to be hilariously fast.
I'm running Ubuntu 10.04 with Compiz enabled. With an nVidia GPU (8200 M)
I am having some problems with recording with my laptop. When I try to record something through the laptops mic, usb webcam mic or with desktop recorders audio record feature all playback is too fast (sounds a bit like alvin and the chipmunks :L ) Is anybody else having this problem, or even better know how to fix it ?
Sorry if this has been asked before, I'm running 10.10 and had never tried recording before I upgraded to 10.04. I had the same problem in 10.04 though.
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 just installed Lucid Lynx RC 1 on my MSI Wind U100 netbook. When I tried to play a video on it I was informed of a lack of codecs, so I downloaded my video player of choice: VLC media player. When I tried to play the video, there was audio but the screen was black. The same thing happened when I downloaded to codecs and used the stock video application.
I use record mydesktop to record what i do in mydesktop. But when i stop record. This box appear. I wait... wait... and wait. But the process encode never complete .
I have Ubuntu 10.10 installed at work on my Dell Optiplex 755, which runs perfect. So I decided to install Ubuntu on my home desktop, which so far has been a mistake. Booting up takes almost 5 minutes, after I login it takes about 2 minutes to get to my desktop, typing in any application (even a shell) is horribly lagged, almost to the point where the PC is unusable. I also get extreme lag when executing programs, or just simply clicking a submit button. It will take 2-10 seconds to actually click or execute. The weird part is visual effects extra works perfect and smooth.

Note: The graph has quite a few drop downs (as you can see the minimum is very low). I've also ran badblocks on the drive which came back with 0 errors. Do I need a special driver for my hard drive? I'm attempting to watch a movie on [URL] and it works fine as long as I continually move my mouse, when I stop moving the mouse the video gets jumpy.
I like to make tutorials on several different things, and since I'm a ubuntu user now, I found Record my Desktop. The thing is, When I stop the video, the encoder takes FOREVER! I left it there for over 5 minutes and it's still at 0%.
I don't know whether it has anything to do with the current problem, but Plymouth used not to appear at all until I followed these instructions (or actually I took them from another thread but I can't find it at the moment and these are the same).
I don't know whether it's possible to take them during booting so I've taken these photos with a mobile and retouched in gimp to remove reflections (more or less), and since I'm no pro photographer nor photoshop/gimp master they look as they look. They should do to demonstrate the problem, though.
Either recordmydesktop produces corrupted files or nothing (mencoder, ffmpeg, kdenlive, pitivi) can open it. (How come totem can?) I need to just stick some text and some sound on this clip but nothing works.
I have just upgraded my box to be more multimedia friendly and one of the upgrades was to improve the sound card. I decided to get the Asus Xonar DX pci-e card. I have it working but the speakers are not plugged into the front output socket as the xonar dx only plays sound from side surround output. Will the sound be any better from the front out on my 2.0 speaker system or is the sound being directed out of the side surround out full quality? How to overcome this discrepancy?
i want to connect two videos into one. let's take two videos from videos as an example. i want my final video to have the height = height of first video + height of second video and width = max(width of first video, width of second video). in the upper part the first video is played whereas in the lower part the second video is played.
do you know how to do it under linux, the best possibility while using mencoder, ffmpeg or any other command line command?
Got this weird problem. I just installed 10.10 to my Thinkpad W510. I am trying to install the proper codecs required to play .avi and other files. I can hear sound, but no vide

VLC started to playing only the audio and not the video, I tried setting the video preferences but all video outputs didn't work. How do I get my video back.
I have recently swapped over to debian (KDE 32bit) from linux mint, however vlc only plays audio, no video (This is for .avi's, .wmv's and rtsp streams, probably others but that what i have available to try). I've installed debian multimedia and dragon player will play .avi's fine, though crashes with .wmv's .

My partner is a teacher and has downloaded some videos from a teacher's resource site but can't seem to play them in Ubuntu. They play fine in Windows XP using Windows Media Player but they only play a few seconds in VLC or Totem and then freeze. The files in question seem to be normal MPG (MPEG-1) video files but somehow VLC and Totem choke on them. I have installed all restricted video formats including w32codecs but still no joy. My partner is threatening to go back to Windows!
I was setting up my Totem Movie Player on Ubuntu 9.10 and at first it wouldn't play dvds at all. So, I went online and entered these two commands into the terminal to play restricted dvds.
DVDs will now play on Totem, but now I don't have any video. I can hear sound and if click around the screen I can get it to play but I still don't have any video. I also tried both dvd drives on my computer and tried different DVDs. Still same thing.
I got my video files from my external hard drive to play, except that all the video's are all negative. Is there a setting to adjust this? I tyred to to go threw the player and see if I changed the settings some how.I even tried other players. I had been watching ..... videos earlier, it was a little choppy video but colours were fine, then I think loaded the flash players and after that the colour went to negative.
I can play a video on XP, but there's no audio in Lucid. The hardware is a Lenovo SL400, 2GB RAM, 7200rpm drive w/ 36GB free, and an Intel T5870 Core 2 Duo 2GHz CPU.Media player and Banshee fails to play the video with the error messageNo packages with the requested plugins foundThe requested plugins areWindows Media Audio 9

I'm having a really random intermittent fault with video files... all kinds... and also happens with different media players... they lock up the entire system but when i reboot they'll play fine...could this be the graphics card? it's a Sparkle Nvidia Geforce 9500.... is there any reccomendations for a suitable replacement that doesn't cost the earth... I'm looking at starting 3D animation too, so was looking to upgrade anyway...there was some kind of error that randomly popped up once or twice when it was playing files...
I have a WMV video which plays in XP but fails in 32-bit Ubuntu Lucid (same machine, dual boot), kernel 2.6.32-22 on a Lenovo SL400 w/ 2GB RAM, 36GB HD free and an Intel Core 2 Duo T5870 2GHz CPU.

I have a dvd-video disc (that is, one like those you buy or rent, out of the shelf) which I have played before. So I'm positively sure it plays and is in good condition. Now, I run mplayer on it, and what do I get? code...
I have had F11 installed for over a week. When I play a video or a sound file it plays fast. All the audio is whinny and voices are high like its playing to fast. If i match the time it does play about 6 seconds fast.
I recently installed Fedora 12 on a new gigabyte mb and for unknown reasons to me videos from ..... and others run very fast (5X) or more, and I'm also unable to get audio to work. All this only happens if I'm using KDE, all work ok in GNOME.
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.
