increase volume (louder) with ffmpeg

The <audio_volume> is a number. 256 is normal. I think if you use 512 then it will double the volume. I got the information from here:-http://lists.mplayerhq.hu/pipermail/...ry/013869.html

ffmpeg -i <input_file> -vol <audio_volume> -acodec <audio_codec> <other_parameters> <output_file> 

MediaInfo in linux - The simple way to get detail media info instead of ffmpeg

Normally, it’s a pain finding stream, codec or bitrate information for media files.

Some information can be discovered using
1    file [some_file].avi
2    ffmpeg -i [some_file].avi

However, there is a better way of doing it using mediainfo[-gui] package available from this site.
01    mkdir -p ~/software/mediainfo
02    cd ~/software/mediainfo
03    echo "http://mediainfo.sourceforge.net/en/Download/Fedora#11.x86_64" > links.txt
04    wget http://downloads.sourceforge.net/mediainfo/mediainfo-gui-0.7.19-1.x86_64.Fedora_11.rpm
05    wget http://downloads.sourceforge.net/mediainfo/mediainfo-0.7.19-1.x86_64.Fedora_11.rpm
06    wget http://downloads.sourceforge.net/mediainfo/libmediainfo0-0.7.19-1.x86_64.Fedora_11.rpm
07    wget http://downloads.sourceforge.net/mediainfo/libmediainfo0-devel-0.7.19-1.x86_64.Fedora_11.rpm
08    wget http://downloads.sourceforge.net/zenlib/libzen0-0.4.3-1.x86_64.Fedora_11.rpm
09    wget http://downloads.sourceforge.net/zenlib/libzen0-devel-0.4.3-1.x86_64.Fedora_11.rpm
10    wget http://downloads.sourceforge.net/zenlib/libzen0-devel-0.4.3-1.x86_64.Fedora_11.rpm
11    wget http://downloads.sourceforge.net/zenlib/libzen0-devel-0.4.3-1.x86_64.Fedora_11.rpm
12    wget http://downloads.sourceforge.net/zenlib/libzen0-devel-0.4.3-1.x86_64.Fedora_11.rpm
13    sudo yum localinstall --nogpgcheck *.rpm

Now, you are able to see all information in the command line mode with:
1    mediainfo [some_file].avi

Or launching
1    mediainfo-gui

3 level caching

3 level loader benefit :

• Faster respone ( vs Disk load)
• Less RAM require (vs RAM cache

But the limited:

• Code Complex
• More CPU resource require.

3 level caching include:

VRAM (RAM of video card) <--> RAM <--> Disk

A file may be in VRAM, RAM or Disk and depend on size and frequency using.

The target. Less RAM require, Less Disk Work,  low latency.

bandwidth.
pattern

Size x Frequency = Bandwidth

100 MB x 10 = 1000 MB.
-----
RAM Cache - 100 MB
Disk work - 100 MB. (need more than 60 cycles to loading) - Low respone - More Ram Require

1MB x 100 = 1000 MB.
-------
RAM Cache - 1 MB
Disk work - 1MB (Need 1 cycles to loading). - low latency - but Less RAM Require.

Caching Rule depend on:
Base on the respone level (Priority): 5 - 4 -3 - 2 -1.
Base on RAM Size: memory of application.
Base on File size : --> RAM require - Disk Work
Base on frequency: --> RAM require - Disk work


 So in terrain case:
I remember about google map. They have something like Level of Detail :D (Web again).
- The high level mipmap (1 or 2 level) is high frequency, low latency and big size. --> VRAM cache.
- lower mipmap is current load (or prepair to load) low latency and small size --> RAM cache.
- The other lower level geomip map is less frequency, higher latency and small size --> Disk Load.

Install windows font for CentOS

Install Windows Font for CentOS

You need to download font package. In Terminal, type:

wget http://www.my-guides.net/en/images/stories/fedora12/msttcore-fonts-2.0-3.noarch.rpm

shutter ... The Screen Capture in Ubuntu and CentOS

Shutter is a good screen capture. It's too convinent for take a shot, work well on small area or all screen and support for export image to local file system or 1 click upload to Image hosting provider.


Too easy to install shutter in ubuntu/xubuntu ... You just find it in ubuntu software center


But for CentOS/Fedora or other linux. You must do something more


First Stage, you need download rpm file. Use Terminal and type :

 $ wget http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-1.el6.nux.noarch.rpm

After that, you need install it with this command

 $ wget http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-1.el6.nux.noarch.rpm

Change "enable" value to '0' in nux-dextop.repo

$ sudo vi /etc/yum.repos.d/nux-dextop.repo

 And final stage is :

$ sudo vi /etc/yum.repos.d/nux-dextop.repo

To run it. Press Alt + F2 and type "Shutter"
