rotate an mpeg 180 degrees in python

You can use the ffmpeg library in Python to rotate an MPEG video 180 degrees. Here's a Python code snippet that uses the subprocess module to call ffmpeg through the command line:

main.py
import subprocess

video_file = "path/to/video_file.mp4"
output_file = "path/to/output_file.mp4"

# Execute ffmpeg to rotate the video 180 degrees
subprocess.call(['ffmpeg', '-i', video_file, '-vf', 'transpose=2,transpose=2', '-codec:a', 'copy', output_file])

8 lines

In the above code snippet, ffmpeg takes the input video file (video_file) and rotates it 180 degrees using the -vf flag with the transpose filter. The -codec:a copy option will copy the audio stream from the input file without re-encoding it.

After executing the command, the rotated video is saved to the output file (output_file).
