[Pixiv] ffmpeg / exiftool Invalid data

[github-account1111]

Getting the following ffmpeg error:

[concat @ 0000020020422500] Line 3: duration not allowed if safe
C:\Users\user\AppData\Local\Temp\tmpzpq81gtg/ffconcat.txt: Invalid data found when processing input

Relevant config portion:

{
  "postprocessor": {
    "ugoira-copy": {
      "name": "ugoira",
      "extension": "mkv",
      "ffmpeg-args": [
        "-c",
        "copy"
      ],
      "libx264-prevent-odd": false,
      "repeat-last-frame": false
    }
  },
  "extractor": {
    "pixiv": {
      "refresh-token": "<redacted>",
      "tags": "translated",
      "filename": "{date:%Y%m%d}-{id}{num:?//>02}.{extension}",
      "directory": [
        "{user[account]}-pixiv"
      ],
      "ugoira": true,
      "postprocessors": [
        {
          "name": "exec",
          "command": [
            "exiftool",
            "-overwrite_original",
            "-title=https://www.pixiv.net/en/artworks/{id}",
            "{_path[4:]}"
          ]
        },
        "ugoira-copy"
      ]
    }
  }
}

I looked under C:\Users\user\AppData\Local\Temp\tmpzpq81gtg, and there were a bunch of images, so I think it at least succeeds to a certain point.

Add "-safe", "0" to your ffmpeg-args.

I've never had this error personally, but maybe your FFmpeg is rather old and needs safe-mode disabled.

In other news, setting timecodes with mkvmerge is now supported: e718dd7. You don't need to configure anything extra for that, just an mkvmerge binary in PATH.

Updating ffmpeg did fix it, thank you.
Interestingly the one I had was only a year old.
