[FFmpeg-user] FFPROBE and Tags in MOV/MP4 files

[Dave Navarro, Jr.]

No, the Title and Comments I am getting.  In Windows 7, enter some keywords under "tags".  They get saved in the file, but FFPROBE doesn't display them.

I replicated your use-case in win 7 by adding a title and comments and this command produced:
ffprobe -v quiet -show_entries format -show_private_data -print_format json K:\fixed.mov {
    "format": {
        "filename": "K:\\fixed.mov",
        "nb_streams": 2,
        "nb_programs": 0,
        "format_name": "mov,mp4,m4a,3gp,3g2,mj2",
        "format_long_name": "QuickTime / MOV",
        "start_time": "0.000000",
        "duration": "5632.625000",
        "size": "6191240703",
        "bit_rate": "8793400",
        "probe_score": 100,
        "tags": {
            "major_brand": "qt  ",
            "minor_version": "512",
            "compatible_brands": "qt  ",
            "encoder": "Lavf57.25.100",
            "title": "testooooo",
            "comment": "leaf example comment for dave navarro, possibly from chilli peppers, but probably not"
        }
    }
}

Hopefully that resolves your issue?

Best,

Kieran.
