如何访问播客元数据？
我正在尝试访问有关播客的元数据，例如节目注释/描述、节目标题和图标图像。我至少部分使用 ContentResolver 来查询大部分 AudioColumns 信息，但由于某种原因 ALBUM_ART 丢失，似乎没有描述列，而且一般来说，不清楚映射是什么。由于播客不是歌曲，因此它们通常没有“作曲家”、“艺术家”和“专辑”，它们有节目标题、剧集标题、主持人等。是否有关于播客元数据通常使用哪些标准的信息以及如何有效地访问它？
I'm trying to get access to the metadata about podcasts, such as the show notes/description, the show title and the icon image. I'm at least partially using ContentResolver to query for most of the AudioColumns information, but for some reason ALBUM_ART is missing, there seems to be no column for the description, and in general, it's not clear what the mapping is. Since podcasts are not songs, they don't generally have "composers", "artists" and "albums" they have show titles, episode titles, hosts, etc. Is there any information out there on what standards are generally used for podcast metadata and how I can efficiently access it?

我在播客方面做了大量工作，发现根本没有标准，而且您会发现元数据种类繁多。媒体内容提供商绝对面向音乐而不是播客，并且它提取的信息（使用 MediaScanner）是您免费获得的全部信息。
为了获得更好的信息，您需要直接从媒体中提取它。如果您可以访问 RSS 信息，您通常可以在那里获得好的信息（至少例如描述），但我怀疑您可能没有这些信息。
I've done a considerable amount of work with podcasts, and have found that there are no standards at all, and there's a huge variety in the metadata you'll find. The media content provider is definitely oriented towards music as opposed to podcasts, and the information it extracts (using the MediaScanner) is all that you'll get for free.
To get better information you'll need to extract it from the media directly. If you have access to the RSS information, you can often get good information (such as description at least) there, but I suspect you probably don't have that.
