Usually, I have to deal with video files to make some tests, so I have decided to create this space to save all those little tips I need from time to time.

First at all, install mencoder:

• sudo apt-get install mencoder

The command:

• mencoder -oac copy -ovc copy test_1.avi test_2.avi testN.avi -o completeFile.avi

I found a great post right here: http://forums.liveleak.com/showthread.php?t=1716

The short version:

The command:

• ffmpeg -i input.avi -b 2028k -s 640×480 -r 30 -acodec copy output.flv

Little explanation:

 ffmpeg: the program
 -i input.avi: the input file
 -b 2028k: the output bitrate
 -s 640x480: the output resolution
 -r 30: the output frames per second
 -acodec copy: the output audio codec
 output.flv: the output file

The command:

• ffmpeg -i example.avi -vn -acodec pcm_s16le -ar 44100 -ac 2 example.wav

The command:

• ffmpeg -i input.flv -an -vcodec copy output.flv

Where output.flv is the video without sound.

The command:

• ffmpeg -vcodec copy -i images.mpg -i sound.mp3 output.mpg
