Save_path = video.with_suffix( '.metadata' + video.suffix) Python script import subprocessįrom typing import Dict def add_metadata( video: Path, For reference you can check Matroska spec for MKV and Kodi docs for MP4. Since the kwargs get passed verbatim, I tried to get clever and do this outfile ffmpeg.output(infile, test-out. So I cant do the equivalent of ffmpeg -i test.mkv -map 0:1 -map 0:2 out.mkv. While that worked for a single stream, I cant use it for multiple streams since you cant duplicate kwargs. Not all containers support every metadata. Thanks alphabetaxz.Were getting real close. Use -map_metadata 0 to copy over existing meta tags without changing them.Use -c copy to copy streams directly without encoding.When split into lines: ffmpeg -i video.mkv ` With ffmpeg, adding metadata is simply including -metadata key=value arguments in the command: ffmpeg -i video.mkv -c copy -movflags use_metadata_tags -map_metadata 0 -metadata title= 'Hello World' -metadata year= 2020 This answer on StackOverflow put me on the right path. ffmpeg commandįfmpeg supports practically anything under the sun, including adding metadata.
