How to use python's ffmpeg library

To use the FFmpeg library in python, you can use the ffmpy library or the subprocess library.

The sample code using the ffmpy library is as follows:

from ffmpy import FFmpeg

input_file = 'input.mp4'
output_file = 'output.avi'

ff = FFmpeg(inputs={input_file: None}, outputs={output_file: '-c:v mpeg4 -b:v 800k'})

ff.run()

The sample code for using the subprocess library is as follows:

import subprocess

input_file = 'input.mp4'
output_file = 'output.avi'

command = 'ffmpeg -i {} -c:v mpeg4 -b:v 800k {}'.fORMat(input_file, output_file)
subprocess.call(command, shell=True)

In both examples, we used an MPEG-4 encoder and a bitrate of 800k to encode the input video and save it as an output file. You can modify the encoder, bitrate, and other parameters as needed.
