Downloading Pixiv ugoira as GIF

[MarqFJA87]

Since Pixiv's latest site-wide update broke PixivUtil2, I've had to fall back on gallery-dl for downloading Pixiv illustrations. It's been working decently overall, with one exception: any ugoira posts are always downloaded as a zip file containing all the individual frames of the animation as images. Is there a way to download such posts as GIFs instead?

My condolences

--ugoira gif

You should also set the ugoira option to "original" for better quality: -o ugoira=original

Also, I've been trying that command line method you suggested, and I keep running into the following error.

[postprocessor.ugoira][error] Unable to invoke FFmpeg (FileNotFoundError: [WinError 2] The system cannot find the file specified)

It keeps happening even after I added an ugoira postprocessor and set it to point to the location of the FFMPEG folder I already use. What am I doing wrong?

{
    "extractor": {
        "pixiv": {
            "ugoira": "original",
            "path-extended": false,
            "postprocessors": {
                "name": "ugoira",
                "extension": "gif",
                "ffmpeg-args": ["-filter_complex", "[0:v] split [a][b];[a] palettegen [p];[b][p] paletteuse"],
                "repeat-last-frame": false
            }
        }
    }
}

The FFmpeg error is most likely due to extended paths, which can be worked around by disabling path-extended

Nope, it just downloads an image folder made of the 100+ individual frames.

... However, I initially made a formatting error in the process of trying to insert that block of code, which if I understand correctly prompted gallery-dl to ignore the config file entirely, returning the following message.

[config][error] JSONDecodeError when loading 'C:\Users\marq_\gallery-dl\config.json': Expecting ',' delimiter: line 275 column 17 (char 7341)

For some reason, however, this was followed by it managing to download a GIF file, albeit it's broken (it ends in *.gif.part, and changing it to *.gif just causes IrfanView to reveal it's just a static JPG image). Fixing the formatting error, on the other hand, just returned things back to downloading the individual frames as images.

EDIT: Here are my full config settings for Pixiv, in case this may help.

        "pixiv":
        {
            "refresh-token": null,
            "avatar": false,
            "tags": "japanese",
            "ugoira": "original",
            "path-extended": false,
            "postprocessors": {
                "name": "ugoira",
                "extension": "gif",
                "ffmpeg-location": "D:/Programs/ffmpeg/bin/ffmpeg.exe",
                "ffmpeg-args": ["-filter_complex", "[0:v] split [a][b];[a] palettegen [p];[b][p] paletteuse"],
                "repeat-last-frame": false
            },
            "directory": ["{category}", "{user[name]} ({user[id]})"],
            "filename": "{id}_p{num} - {title}.{extension}",
            "postprocessors": ["pixiv_content"]
        },

You need to combine the two postprocessors entries, otherwise the first one is ignored.

{
    "extractor": {
        "pixiv": {
            "refresh-token": null,
            "tags": "japanese",
            "ugoira": "original",
            "path-extended": false,
            "directory": ["{category}", "{user[name]} ({user[id]})"],
            "filename": "{id}_p{num} - {title}.{extension}",
            "postprocessors": [
                "pixiv_content",
                {
                    "name": "ugoira",
                    "extension": "gif",
                    "ffmpeg-location": "D:/Programs/ffmpeg/bin/ffmpeg.exe",
                    "ffmpeg-args": ["-filter_complex", "[0:v] split [a][b];[a] palettegen [p];[b][p] paletteuse"],
                    "repeat-last-frame": false
                }
            ]
        }
    }
}

OK, uh, where do I add the extra code in the actual postprocessor? This is the full entry, down in the postprocessors section of the file.

		"pixiv_content": {
			"name": "metadata",
			"event": "post",
			"filename": "{id}_t.txt",
			"mode": "custom",
			"format": [
				"Artist: {user[name]} ({user[id]})",
				"Title: {title}",
				"Date: {date}",
				"Caption: {caption}",
				"Tags: {tags!S}"
			]
		},

Does the name parameter matter at all? Because that's the only clash I see, everything else I assume I can put anywhere in the block.

[mikf]

Just copy-paste the config snippet from #7252 (reply in thread). The pixiv_content and ugoira post-processors are already combined in it.

[MarqFJA87]

Yes, it works! Say, what about Fanbox? Do I copy the same block to its own postprocessor parameter the same way with Pixiv?

[mikf]

Fanbox doesn't have Ugoira animations, does it? At least gallery-dl doesn't have any special Fanbox Ugoira code.

But yes, you would just copy the same postprocessors block into your fanbox settings.
