Im using slackware 13.1 , and tried to record my desktop with recordmydesktop but the qualite was very bad, then i googled the subject little, and i found this commande with ffmpeg here is it:
And i have this output:
I've been using RecordMyDesktop to do some simple videos (no fancy effects) and when I play them back, they are all jaggedy and pixelated and barely viewable.

The original videos I am trying to get are conference recordings:[url]
I also tried downthemall firefox pluggin but it doen not see the videos, it only sees links to flashplayer install or something.
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 record my desktop for instructional aids but saying "And now click here" is not too cool and the user could miss the what-where. How do I have each mouse click play an audio sound or have a right click cause circular waves and a left click square waves around the mouse? Something graphic and/or audio. (My android tablet has the option of a click sound when a touch is recognized.)
I hope for something more obvious for the viewer. I don't use Compiz but would be willing to try it if that is the answer. Turning on Visual Effects (x) Extra does not do it. I didn't see anything in Assistive Technologies.

View 14 Replies View RelatedI have recently grown to love Linux for its fast reliable virus free and clean uncluttered operation for word, photo, spreadsheet and especially internet use. As a pro musician I've used Sonar on Windows XP for years and it's a great programme, however for various reasons I would like to abandon Windows completeley and I like Audacity, Ardour and Rosegarden. Although basic, these would get me through most of my projects as a guitar teacher. My questions are: is it considered essential to install a real-time kernel or can you get by nudging audio by 50 ms or so. Ubuntu Studio would be the answer I guess although on my HP dual core I get mouse and keyboard freezes with Ubuntu after 9.04! - weird. Fedora has always been rock solid on my machines although I understand that there is no real time package for versions after F12. Are there musicians out there that use Fedora? - which versions and what set up.

View 1 Replies View RelatedI have xscreensaver installed and configured. I have it set to turn on after 5 minutes, cycle every 5 minutes. I have acpi setup to blank my monitor after 10 minutes and power off after 15 minutes. The problem is, sometimes it works, sometimes it doesn't. I haven't figured it out. The service from what I can tell only runs when the screen saver is active. So checking ps -e doesn't tell me much, and since there isn't a true problem it is not recording anything in the logs.

I am looking for an option to convert .vob file to mp4 format. Command "ffmpeg -i S.vob x.mp4" is giving error message "[libfaac @ 01cac110] Unable to load libfaac.dll". I tried to convert in other formats like .avi with the same command and got success. Conversion is decreasing the quality like hell. Though size of the file after conversion is as big as original then why this bad quality. Some where I have read if I will not specify any argument it will keep the quality same but here it is not happening. Not sure why....
View 2 Replies View RelatedI want to start recording when someone starts talking, and stop recording when it becomes silent. I guess if there is stream audio processing tool like ImageMagick, so I can strip away blank sections like this:
$ rec -t wav - | wavefilter -strip-blank=3sec | lame - >record1.mp3
EDIT This question is resolved by using:
$ rec -t wav - silence 1 0.1 3% -1 1.0 3% | lame - >record1.mp3

At least one output file must be specified Actually the video has embedded subtitles. I thing that is stream 0.2 in real media container. How can i pull that data out ?
I have a TV tuner card with its output connected to the CD in of an integrated sound card. Video is OK, and the sound also gets thorough (to the line out) when running xawtv, for example. However, I found no ways yet for recording it.I'm running Ubuntu 10.10 with ALSA drivers. Pulseaudio was running in the beginning, now it doesn't, but it doesn't seem to make much difference.
capturing with VLC, using plughw:0,0 as the audio capture device. (Result: no sound track at all in the resulting video.)arecord, then aplay.alsamixer. The capture source is set to "CD" (and on the input side it's also "CD" where I can effectively modify the volume for audio going through...), but still no result.
I've created some time-lapse videos from photos, using this command: ffmpeg -i IMG_%03d.JPG -s 1440x1080 -sameq video.MP4
And it worked great. Now I want to join several of these time-lapse videos to make a single, longer video (all the input videos have the exactly same format). I already tried using: cat video1.MP4 video2.MP4 > stitch.MP4
but the output ends up being equal to video1.MP4, I don't want to transcode nor changing any parameter of the video, I just want a end-to-end stitching, as if those videos were on a playlist.

I am running a server which is hosting a site where members can upload videoclips. I noticed that upon upload a thumbnail is not created for the videoclip. I found out that ffmpeg needed to be properly installed and in my case ffmpeg-php as the site runs on php. So far so good. I followed the instructions found somewhere to install ffmpeg-php but stall at the command: dot slash configure && make The error I get is:
checking for egrep... grep -E
checking for a sed that does not truncate output... slash slash bin slash sed
checking for gcc... no
checking for cc... no
checking for cc... no
checking for cl... no
configure: error: no acceptable C compiler found in $PATH
I presume it's because gcc is missing. how I can start tackling the problem and ultimately get gcc running so I can install the ffmpeg? I am really sorry I was hoping to elaborate a bit more but I get an error: You are only allowed to post URLs to other sites after you have made 15 posts or more. so I guess I need to wait and describe it differently.
