===Installing FFmpeg on Ubuntu ===
To use FFmpeg on Ubuntu, you need to install it first. You can do this by running the following command in the terminal: 
<code>sudo apt install ffmpeg</code> 
 
==Basic usage==
Once you have installed FFmpeg, you can use it to perform various tasks related to video and audio processing. Here are some basic commands to get you started: 

=== Convert video from one format to another===
* This command will convert the input_video.avi file to output_video.mp4 format.
<code>ffmpeg -i input_video.avi output_video.mp4</code> 
 
=== Convert audio from one format to another===
* This command will convert the input_audio.mp3 file to output_audio.ogg format.
<code>ffmpeg -i input_audio.mp3 output_audio.ogg</code> 
 
=== Extract audio from a video file===
* This command will extract the audio from the input_video.mp4 file and save it as output_audio.mp3.
<code>ffmpeg -i input_video.mp4 -vn output_audio.mp3</code> 
 
=== Extract frames from a video file===
* This command will extract one frame per second from the input_video.mp4 file and save them as PNG images in the output_frames folder.
<code>ffmpeg -i input_video.mp4 -r 1 -f image2 output_frames/frame05d.png</code> 
 

===Merge audio and video files===
* This command will merge the input_video.mp4 and input_audio.mp3 files and save the result as output_video.mp4.
<code>ffmpeg -i input_video.mp4 -i input_audio.mp3 -c:v copy -c:a aac -strict experimental output_video.mp4</code> 
 

==More advanced usage==
FFmpeg can be used for many advanced video and audio processing tasks, such as trimming, cropping, resizing, adding watermarks, etc. Here are some examples: 
=== Trim a video file===
* This command will trim the input_video.mp4 file from the 10th to the 20th second and save the result as output_video.mp4.
<code>ffmpeg -i input_video.mp4 -ss 00:00:10 -to 00:00:20 -c copy output_video.mp4
</code> 
 
=== Trim a Audio file===
* This command will will make a 5 second copy. From 00:00:05 to 00:00:10
<code>ffmpeg -i input.mp3 -ss 00:00:05 -t 00:00:05 output.mp3</code> 
* -i input
* -ss start time
* -t time, for how long.
* Time syntax HH:MM:SS
* output.mp3 name of output file

=== Crop a video file===
* This command will crop the input_video.mp4 file to 480x360 pixels, starting from (120,60) coordinates, and save the result as output_video.mp4.
<code>ffmpeg -i input_video.mp4 -filter:v "crop=480:360:120:60" -c:a copy output_video.mp4</code> 
 
=== Resize a video file===
* This command will resize the input_video.mp4 file to a width of 640 pixels and adjust the height automatically, maintaining the aspect ratio, and save the result as output_video.mp4.
<code>ffmpeg -i input_video.mp4 -vf scale=640:-2 -c:a copy output_video.mp4</code> 
 
=== Add a watermark to a video file===
* This command will add a watermark.png image to the top-left corner of the input_video.mp4 file and save the result as output_video.mp4.
<code>ffmpeg -i input_video.mp4 -i watermark.png -filter_complex "overlay=10:10" -codec:a copy output_video.mp4</code>,br>
 

===Concatenating Videos===
Concatenating videos using the concat demuxer
The concat demuxer is a FFmpeg component that allows you to concatenate videos by creating a text file that lists the paths of the input video files in the order you want them to be concatenated. 
 
====Create a text file====
Create a new text file called concat.txt and list the paths of the input video files in the order you want them to be concatenated. For example: 
<pre>
file '/path/to/video1.mp4'
file '/path/to/video2.mp4'
file '/path/to/video3.mp4'
</pre>

====Concatenate the videos====
<code>ffmpeg -f concat -safe 0 -i concat.txt -c copy output.mp4</code> 
This command tells FFmpeg to use the concat demuxer (-f concat) and to read the input file paths from the concat.txt file (-i concat.txt). 
The -safe 0 option is used to disable some security checks that could prevent FFmpeg from accessing the input files. The -c copy option is used to copy the video and audio streams from the input files to the output file without re-encoding them, which is faster and preserves the original quality.
 The output.mp4 parameter is the name of the output file.
