I would recommend you to have a look at the code of xset, a tool that's part of X.org, or any other program that can already do these things you want to do (you can disable the screen turning off with xset -dpms + xset s off). In the case of xset, you'll find the source code here, or for when that link will be outdated: http://www.x.org/releases/current/ ...

The easiest way to accomplish this, would be to do the exact opposite of what you're trying to do: first capture still pictures then convert those still pictures to a video (so basically a combination of both above answers) I would: take a minimum of 16 fps as that is the minimum our brain needs to see smooth motion If this is for a web application, ...

It is a kernel bug, limited to monitors connected via Display Port output to an Intel Integrated Graphics. I found it googling [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries,giving up However, this bug has been fixed in Linux 3.16, which can be installed in Ubuntu 14.04. If you are running 14.10, you already have this kernel and you should not have to ...

It means that the system cannot find an appropriate driver for the device (i.e. no driver is 'claiming' it) - it should be supported by the S3 legacy driver, so I'm not sure why that would be the case.

That link is about some odd looking fix for Ubuntu 12.x, I think it might even be detrimental on Ubuntu 14.04 (I did not have to do such a thing). MP4 is the container, check what codec it uses by right clicking -> Properties -> Audio/Video tab: Check container and Video codec I usually use VLC, which can play most formats out of the box, but I just tried ...

I actually found the issue to this problem and thought I'd do the right thing and post it. It would seem that the positioning of the bluetooth receiver in particular USB ports had an impact with the reception between the keyboard/mouse (probably something to do with the fact that it's a mini-pc and the processor and other radio affecting devices are situated ...

Although similar, the pepper flash that comes with chrome is different than the one that is installed from the repos (adobe-flashplugin, or sth like that). I know there is a way to tell firefox to use chrome's but I've never looked into that so not sure if that is your case. Sadly when it comes to flash I think other than checking you are in the latest ...

In gwenview Go to plugins > tools > advanced slideshow If Plugins is empty (by default I think kubuntu doesn't install them) you need to add kipi-plugins I think. There may be a helper anyway once go to Plugins

You can do that with ffmpeg or avconv. To extract a single image: ffmpeg -i input.flv -ss 00:00:14.435 -f image2 -vframes 1 out.png avconv -i input.flv -ss 00:00:14.435 -f image2 -vframes 1 out.png This will seek to the position of 0h:0m:14sec:435msec into the movie and extract one frame (-vframes 1) from that position into a png file. here are two ...

As @AE indicates you can turn off hardware acceleration in chrome in the settings by chrome://settings/ -> 'advanced settings' -> untick 'use hardware acceleration' and restart chrome. I In Firefox It's here: A restart may be required here as well.

During this conversion both video and audio need to be decoded from the original file and then encoded to the target file. In this case the original file happens to have the audio encoded with 'aac' (Advanced Audio Coding). The decoding of the audio is not a problem, only encoding to 'aac' encoded audio seems to be problematic. See the last two lines of the ...

You can try with mediainfo: mediainfo f00000.avi To rename all .avi files in the current directory, run: for f in *.avi;do title=$(mediainfo $f|grep -i "movie name"|cut -d":" -f2);mv -v "$f" "$title";done Install mediainfo using the command: sudo apt-get install mediainfo

There's a good chance, that libavformat.so.54 contains all the symbol needed by Audacity. Tell Audacity to work with that. If necessary trick it, by creating a symlink somewhere, e. g.: ln -s /usr/lib/$(uname -m)-linux-gnu/libavformat.so.54 ~/libavformat.so.53

Please go online (you must have internet connection running) when you try to run that file it will ask to search required codec then say yes it will install required codec, that's it. Otherwise try this one: sudo apt-get install ubuntu-restricted-extras

Try using the command without the backslashes (\), as these may be causing issues on the command line of your shell. The backslashes are used to denote command continuation onto another line, but if you are copying and pasting, then extra tabs and spaces can get picked up. Try using the following one line example: ffmpeg -i oceans.mov -an -c:v libx264 -r 24 ...

I had this problem this morning after messing around with VLC (changing some preferences, trying to add a skin, attempting to get bookmarking working). Finally I went into ~/.config/vlc and deleted everything – next time I started VLC, all was well.

There are two established algorithms that can measure the faithfulness of video to its source. You have to input two video streams, the original source and the encoded version, and the algorithm calculates the faithfulness and outputs a figure. Unfortunately for you, they both require you to supply the un-compressed source along with the compressed video, ...

The error means that /dev/video0 is not a video capture device. Perhaps you need to set another device using: gst-launch-1.0 v4l2src device="/dev/videoX" ! video/x-raw,width=640,height=480 ! x264enc ! h264parse ! rtph264pay ! udpsink host=127.0.0.1 port=5000 Where 'X' is the number of your video capture device. It might also happen that your device ...

For me, changing from the AMD fglrx to the xserver-xorg-video-ati driver in driver management helped. Unfortunately other software doesn't like xserver-xorg so meanwhile I am using rekonq or konqueror which seems not to be lagging.
