I just learned about cool VIM option from a collegue:
:colorscheme evening
What it does it makes configurations in vim edit look brighter like you seen in below screenshots.
– Before :colorscheme evening vim command
– After :colorscheme evening
The option is really useful as often editing a config in vim on a random server is too dark and in order to read the config you have to strain your eyes in long term leading to eye damage.
Any other useful vim options, you use daily?
I'm starting to learn some video editing, as I need it sometimes for building client websites.
As a Linux user I needed to have some kind of software for amateur video editing.
For Microsoft Windows OS, there are tons of video editor programs both free and proprietary (paid).
Windows users can for instance use the free software program VirtualDub (licensed under GPL license) to easily cut movie scenes from a video.
Unfortunately VirtualDub didn't have a Linux or BSD version so in my case I had to look for another soft.
I consulted a friend of mine who recommended a video editor program called LiVES.
If you haven't done any video editing previously on Linux (like my case was), you will certainly be happy to try LiVES
LiVES can extract only sound from videos, cut selected parts (frames) from videos and do plenty of other nice stuff. It is just great piece of software for anyone, who needs to do simply (newbie) video editting.
With LiVES even an amateur video editor like me could, immediately learn how to chop a movie scenes …
To master the basics and edit one video in FLV format it took me about 1 hour of time, as in the beginning it was confusing to get confortable with the program scenes selector.
One downside of LiVES it failure to open a FLV file I wanted to edit.
In order to be able to edit the flv movie hence I first had to convert the FLV to AVI or MPEG, as this two (video multimedia formats) are supported by LiVES video editor.
After completing my video scenes chopping to the AVI file I had to convert back to FLV.
In order to complete the convertion between FLV to AVI format on my Debian Linux, I used a program called avidemux
Avidemux has a nice GUI interface and also like Lives has support for video editting, though I have never succesfully done any video edits with it.
Avidemux IMHO is user (completely intuitive). To convert the FLV to AVI, all I had to do was simply open the file FLV file, press (CTRL+S) select my FLV video file format and select the output file extension format to be AVI.
Further on, used LiVES to cut my desired parts from my video of choice. Once the cuts were complete I saved the new cutted version of video to AVI.
Then I needed the video again in FLV to upload it in Joomla, so used ffmpeg – command line tool to do the AVI to FLV file converstion, like so:
hipo@noah:~$ /usr/bin/ffmpeg -i my_media_file.avi my_video_file.flv
Hope this article helps someone aiming to do basic video editting on Linux with LiVES and just like needed FLV to AVI and AVI to FLV convertions.
1. Add Medibuntu package repository
root@ubuntu:~# wget --output-document=/etc/apt/sources.list.d/medibuntu.list \
http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list \
&& apt-get --quiet update \

&& apt-get --quiet update
2. Enable Ubuntu to play Restricted DVD
root@ubuntu:~# apt-get install --yes libdvdread4
...
root@ubuntu:~# /usr/share/doc/libdvdread4/install-css.sh
After that VLC will be ready to play DVDs for some programs which was compiled without DVD, source rebuilt is required.
If DVDs hang you might need to set a Region Code with regionset:
# regionset

root@ubuntu:~# apt-get install non-free-codecs
4. Install Chromium ffmpeg nonfree codecs
root@ubuntu:~# apt-get install chromium
root@ubuntu:~# apt-get install chromium-codecs-ffmpeg-nonfree
5. Install w32codecs / w64codecs
Depending on the Ubuntu Linux installation architecture 32/64 bit install w32codecs or w64codecs
For 32 bit (x86) Ubuntu install w32codecs:
root@ubuntu:~# apt-get install w32codecs
For 64 bit arch Ubuntu:
root@ubuntu:~# apt-get install w64codecs
6. Install ubuntu-restricted-extras meta package
root@ubuntu:~# apt-get install ubuntu-restricted-extras

Unfortunately Gnash is not yet production ready and crashes in many websites …
root@ubuntu:~# apt-get install flashplugin-nonfree flashplugin-nonfree-extrasound swfdec-gnome
13. Install Archive / Unarchive management programs
root@ubuntu:~# apt-get install unace unrar zip unzip p7zip-full p7zip-rar sharutils rar uudeview \

This should be enough to use Ubuntu normally for multimedia Desktop just as MS Windows for most of the daily activities.
Am I missing some important program?
If you're on Linux the questions like, how can I convert between video and audio formats, how to do photo editing etc. etc. have always been a taugh question as with it's diversity Linux often allows too many ways to do the same things.
In the spirit of questioning I have been recently curious, how can a subtitles be added to a flash video (.flv) video?
After some research online I've come up with the below suggested solution which uses mplayer to do the flash inclusion of the subtitles file.
mplayer your_flash_movie.flv -fs -subfont-text-scale 3
While including the subtitles to the .flv file, it's best to close up all the active browsers and if running something else on the desktop close it up.
Note that above's mplayer example for (.srt and .sub) subtitle files example is only appropriate for a .flv movie files which already has a third party published subtitle files.
What is interesting is that often if you want to make custom subtitles to let's say a video downloaded from Youtube on Linux the mplayer way pointed above will be useless. Why?
Well the Linux programs that allows a user to add custom subtitles to a movie does not support the flv (flash video) file format.
My idea on how to create custom subtitles and embed them into a flv movie file is very simple and it goes like this:
1. Convert the .flv file format to let's say .avi or .mpeg
2. Use gnome-subitles or subtitleeditor to create the subtitles for the .avi or .mpeg file
3. Convert back the .avi/.mpeg file with included subtitles to .flv (flash video format)
This methodology is really long and time consuming, but pitily as far as my understanding goes it's the only way to do that on your Linux until now.
To make the conversations between .flv and .avi format you will need to use the ffmpeg – (FFMpeg command line tool video converter), here is how:
– Convert .flv to .avi
debian:~# /usr/bin/ffmpeg -i input_flvfilename.flv output_avifilename.avi
– Convert .avi file to .flv
debian:~# /usr/bin/ffmpeg -y -i /path/to/your/avi/input_avifilename.avi -acodec mp3 -ar 22050 -f flv
/path/to/your/flv/output_flvfilename.flv
The required overall tools which you will have to have installed on your Debian or Ubuntu Linux are:
1. ffmpeg
2. gnome-subtitles
3. subtitleeditor
4. mplayer
You will also have to spend some time to get to know gnome-subtitles or subtitleeditor, but it won't be that long until you get the idea on how to use them.
