(Ie, the title and chapter data are found in separate loops through the metadata output)īut it works and it should save you a lot of time. It's also inelegant as there were many hoops to jump through since it is processing the metadata line by line. This took a good bit to figure out since I'm definitely NOT a Python guy.
Output = sp.check_output(command, stderr=sp.STDOUT, universal_newlines=True) # when it does not get one so we need to capture stderr, # ffmpeg requires an output file and so it errors
If you want to improve please submit pull requests. Python isn't my first language but I noticed you use it so I figure writing it in Python might make more sense. I tested it on several videos and it worked well. If I was writing this again I'd use ffprobe's json options You can get chapters using: ffprobe -i fname -print_format json -show_chapters -loglevel error (Edit: This tip came from via this issue: )
