如何使用exiftool将元数据嵌入到自定义XMP字段中? [英] How can I embed metadata into a custom XMP field with exiftool?

问题描述

有人可以解释一下如何使用exiftool将元数据嵌入MP4文件中的自定义元数据字段吗?我搜索了所有文档，它似乎与需要创建的配置文件有关.这是我正在使用的. (我知道这还没有结束，因为它没有XMP字段，但是我还没有找到一个包含XMP字段的工作示例.

Can someone please explain how to embed metadata into a custom metadata field in an MP4 file with exiftool? I've searched all the docs and it seems to be related to the config file that needs to be created. Here is what I'm working with. (I know this isnt even close, as its not doing XMP fields, but I havent found a single working example with XMP fields yet.

 %Image::ExifTool::UserDefined = (
'Image::ExifTool::Exif::Main' => {
    0xd001 => {
        Name => 'Show',
        Writable => 'string',
        WriteGroup => 'IFD0',    
},
);
1; #end

我要运行的命令是:

 exiftool -config exifToolConfig -show="Lightning" /reachengine/media/mezzanines/2015/02/13/13/CanyonFlight.mp4

在linux环境中运行它.

推荐答案

示例exiftool配置文件包含许多自定义XMP标签的工作示例.

The sample exiftool config file contains a number of working examples of custom XMP tags.

基本上是这样完成的:

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::XMP::Main' => {
        xxx => {
            SubDirectory => {
                TagTable => 'Image::ExifTool::UserDefined::xxx',
            },
        },
    },
);
%Image::ExifTool::UserDefined::xxx = (
    GROUPS => { 0 => 'XMP', 1 => 'XMP-xxx', 2 => 'Other' },
    NAMESPACE => { 'xxx' => 'http://ns.myname.com/xxx/1.0/' },
    WRITABLE => 'string',
    MyNewXMPTag => { },
);

然后命令是

exiftool -config myconfig -mynewxmptag="some value" myfile.mp4
