Concatenate Videos

Description​

The concatenate_videos function concatenates two video files into a single output video. It uses a temporary text file to list the input video files, then runs the ffmpeg command to combine them.

Function Signature:​

def concatenate_videos(input_file_path1: str, input_file_path2: str, output_file_path: str):

Parameters​

  • input_file_path1 (str): The file path of the first video to concatenate.
  • input_file_path2 (str): The file path of the second video to concatenate.
  • output_file_path (str): The file path where the concatenated video will be saved.

Returns​

  • None

Example Usage​

concatenate_videos('video1.mp4', 'video2.mp4', 'output_video.mp4')

Notes​

  • The function generates a temporary text file containing the paths of the videos to concatenate.
  • It uses ffmpeg to perform the concatenation operation with the -f concat and -safe 0 options.
  • After the operation, it removes the temporary file used to list the video files.
  • If an error occurs during concatenation or while cleaning up the temporary file, it is handled and printed to the console.

Error Handling​

  • If an error occurs during the ffmpeg command execution, a subprocess.CalledProcessError is caught and an error message is printed.
  • If there is an issue removing the temporary file, an OSError is caught and printed.
