Video deshake con Linux: stabilize a shaky video with Transcode pt. 2

canon_mossa

Whole an article in the 2013 that was the subject of stabilization of shaky videos.

Notwithstanding that the best outcome would be to use one stabilizer physical (a simple grip with a weight at the lower end) or a accelerometer solidarity (there are those who have made a kinect).

Also in this case we will use Transcode, so if we have not installed it will be necessary to do so:

Terminal: clear the command history

shell

Cencellare command history from the history of the terminal is a simple operation. Default, the last 500 commands type in termilane are stored in the hidden file ".bash_history". The previously typed commands can be read quickly by using the arrow keys ("freccia its" and "down arrow"). This makes it easy to invoke a command recently typed, but it could be a security issue if that session was used by more people. So how does one delete the command history?

Start a program with GUI remotely via SSH

shell

I do not often have to start an application on a remote machine that requires the use of the GUI, more widely in applications to launch and "turn" in background, but it can always happen. I'm thinking for example to those who use a computer as a multimedia station (with XBMC setup is very simple) or even just to experience.

Suffice it to say that you can do, but it is necessary to direct the GUI application to a screen in particular.

Small dictionary of the command line in Linux

shell

Like many other things, also command line is subject to mutations. Mutations that occur very slowly (fortunatamennte) and in some cases do not occur just. The one listed below is a beginner cheatsheet of linuxian, i main controls with which to familiarize when you start to use the (one of) free operating system. Obviously, the guide is not complete, In fact, this little guide is not intended to replace all "man page" (otherwise a person would need?), but want to summarize in a practical and fast the most common commands.

Terminal: delete the login information

shell

After being absent from the blog for the whole month of August, and half of September back at breakneck speed with the usual weekly article. Today we talk about privacy.

The terminal Linux è fantastico, with just a few commands we can have full control over the computer. Vediamo ora nel dettaglio come delete the login information per il computer sul quale siamo loggati.

LibreOffice from terminal: convert to PDF

converter

With today's article we complete the article in the 31 May concerning the Printing from Client to Server, no drivers whatsoever. Perhaps not everyone knows that LibreOffice and OpenOffice integrate between their packages some commands from flipping through the terminal. These commands are identical for all operating systems (you, for Windows) and produce the same results. Among these we see today is the syntax for convert any file type through terminal opened with LibreOffice / OpenOffice in PDF.

The command for Linux is as follows:

Cut a section of video with ffmpeg

shell

Today's article purpose is to be a reference for those who want cut a video from one point to another with ffmpeg ( then using the terminal). Strange, true? To change what products we use highly graphical far more graphics you can imagine.

Often the video is too long to be cut, and a full program (with gui and all) consumes too many resources and slows down the system.

The syntax is very simple, in a single line of terminal

Print without driver, with file upload on Linux servers

canon-pixma-mp495

In today's article I deal with printing. After I compared the various requirements of customers, I came to theorize the idea that the user (utonto) should have to have everything ready. Less software or drivers will be installed, will be more happy and will be less annoying to those who have something else to do.

The illumination came to me sifting between the printer settings that we have in the office. In one of the menus I see that you can upload the PDF to print on the printer's internal memory to print automatically.

Extract the audio track from a video “ffmpeg”

shell

Let's say you have a video from which we extract an audio track. The reasons may be the most varied, we might want to save a special effect in a movie (shot, outbreak, d'atmosphere song, famous phrase, etc.), or part of a song, the possibilities are endless.

Today let's see how you do with ffmpeg, the usual command-line tool that always shot at stake for encode video, slow them down, adapt them to my TV and more.
