| """ | |
| Script to extract video files written by the BMW Drive Recorder in my 2024 model | |
| and rename them using the date and time in the directory names that it writes | |
| into USB storage. | |
| This is free and unencumbered software released into the public domain and comes | |
| with no warranties. | |
| Requirements: | |
| 1. A Python 3 runtime installed. | |
| 2. (Optional, see below) The ffmpeg command line tool installed. | |
| Place in same directory as the DriveRecorder directory extracted from the | |
| vehicle. Run script using Python, like `python3 ./bmw_drive_recorder_extract.py`. | |
| This assumes a directory structure like: | |
| - DriveRecorder | |
| - YYYY-MM-DD_HH-MM-SS(am|pm)_Manual | |
| - Some_Video_File.ts | |
| - Metadata | |
| - ... | |
| Output looks like: | |
| - Extracted | |
| - BMW_YYYY-MM-DD_HH-MM-SS(am|pm).(ts|mp4) | |
| - ... | |
| The script can convert to MP4 along the way using ffmpeg (and a default | |
| codec). For that: | |
| 1. Install the ffmpeg command line utility. | |
| 2. Set CONVERT_TO_MP4_WITH_FFMPEG below to True before running. | |
| Of course, you can edit the script further to change inputs and outputs. | |
| """ | |
| CONVERT_TO_MP4_WITH_FFMPEG = False | |
| import os | |
| import shutil | |
| # Path to the DriveRecorder folder | |
| drive_recorder_path = "./DriveRecorder" | |
| output_path = "./Extracted" | |
| os.mkdir(output_path) | |
| # Iterate over each subdirectory | |
| for subdir in os.listdir(drive_recorder_path): | |
| subdir_path = os.path.join(drive_recorder_path, subdir) | |
| if not os.path.isdir(subdir_path): | |
| continue | |
| for file in os.listdir(subdir_path): | |
| # Find the video file | |
| if file.endswith(".ts"): | |
| dir_date_time = subdir.rsplit("_", 1)[0] | |
| old_video_path = os.path.join(subdir_path, file) | |
| # Rename and move the video file | |
| new_video_name = f"BMW_{dir_date_time}" + ".mp4" if CONVERT_TO_MP4_WITH_FFMPEG else ".ts" | |
| new_video_path = os.path.join(output_path, new_video_name) | |
| if CONVERT_TO_MP4_WITH_FFMPEG: | |
| import subprocess | |
| subprocess.run(['ffmpeg', '-i', old_video_path, new_video_path]) | |
| else: | |
| shutil.move(old_video_path, new_video_path) |
