如何访问播客元数据? [英] How to access podcast metadata?

问题描述

我正在尝试访问有关播客的元数据，例如节目注释/说明，节目标题和图标图像.我至少部分地使用ContentResolver来查询大多数AudioColumns信息，但是由于某种原因ALBUM_ART丢失了，因此似乎没有用于说明的列，并且通常来说，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"，因此他们没有节目标题，剧集标题，主持人等.那里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?

推荐答案

我在播客方面做了大量工作，发现根本没有标准，并且您的元数据种类繁多会找到.媒体内容提供商绝对是针对音乐而不是播客，它所提取的信息(使用MediaScanner)是免费的.

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.

要获取更好的信息，您需要直接从媒体中提取信息.如果可以访问RSS信息，通常可以在那里获得良好的信息(至少是描述)，但是我怀疑您可能没有.

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.
