Usage

FFMPEG provides a wide range of features for media processing, including encoding, decoding, muxing, demuxing, filtering, and streaming. Here are some examples of how to use FFMPEG on Linux:

Convert a video file to a different format

To convert a video file from one format to another, use the following command:

ffmpeg -i input.mp4 -c:v libx264 -c:a aac -strict -2 output.flv

This command will convert the input file input.mp4 to the output file output.flv, using the H.264 video codec (libx264) and the AAC audio codec.

Extract audio from a video file

To extract the audio stream from a video file, use the following command:

ffmpeg -i input.mp4 -vn -c:a copy output.mp3

This command will extract the audio from the input file input.mp4 and save it to the output file output.mp3, using the original audio codec (-c:a copy).

Apply a filter to a video file

To apply a filter to a video file, use the following command:

ffmpeg -i input.mp4 -vf "scale=640:360" output.mp4

This command will resize the input file input.mp4 to a resolution of 640x360 pixels using the scale filter and save it to the output file output.mp4.
