    1. API Description

    Domain name for API request: vod.tencentcloudapi.com.

    This API is used to search for media information and supports filtering and sorting the returned results in many ways. You can:

    • Specify the file ID set FileIds to return the media files with any ID in the set.

    • Fuzzily search by multiple media filenames Names or multiple descriptions Descriptions.

    • Search by multiple filename prefixes NamePrefixes.

    • Specify the category set ClassIds (please see the input parameters) to return the media files in any category in the set. For example, assuming that there are categories of Movies, TV Series, and Variety Shows, and there are subcategories of History, Action, and Romance in the category of Movies, if Movies and TV Series are specified in ClassIds, then all the subcategories under Movies and TV Series will be returned. However, if History and Action are specified in ClassIds, only the media files in these two subcategories will be returned.

    • Specify the tag set Tags (please see the input parameters) to return the media files with any tag in the set. For example, assuming that there are tags of ACG, Drama, and YTPMV, if ACG and YTPMV are specified in Tags, then any media files with either tag will be retrieved.

    • Specify the file type set Categories (please see the input parameters) to return the media files of any type in the set. For example, assuming that there are Video, Audio, and Image file types, if Video and Audio are specified in Categories, then all media files of these two types will be retrieved.

    • Specify the source set SourceTypes (please see the input parameters) to return the media files from any source in the set. For example, assuming that there are Record (live recording) and Upload (upload) sources, if Record and Upload are specified in SourceTypes, then all media files from these two sources will be retrieved.

    • Specify the live stream code set StreamIds (please see the input parameters) to filter live recording media files.

    • Specify the video ID set Vids (please see the input parameters) to filter live recording media files.

    • Specify the creation time range to filter media files.

    • Specify a text string Text for fuzzy search by media filenames or descriptions. (This is not recommended. Names, NamePrefixes, or Descriptions should be used instead.)

    • Specify a media file source SourceType for search. (This is not recommended. SourceTypes should be used instead.)

    • Specify a live stream code StreamId for search. (This is not recommended. StreamIds should be used instead.)

    • Specify a video ID Vid for search. (This is not recommended. Vids should be used instead.)

    • Specify a creation start time StartTime for search. (This is not recommended. CreateTime should be used instead.)

    • Specify a creation end time EndTime for search. (This is not recommended. CreateTime should be used instead.)

    • Search by any combination of the parameters above. For example, you can search for the media files with the tags of "Drama" and "Suspense" in the category of "Movies" or "TV Series" created between 12:00:00, December 1, 2018 and 12:00:00, December 8, 2018. Please note that for any parameter that supports array input, the search logic between its elements is "OR", and the logical relationship between parameters is "AND".

    • Sort the results by creation time and return them in multiple pages by specifying Offset and Limit (please see the input parameters).

    • Specify Filters to return specified types of media information (all types will be returned by default). Valid values:

      1. Basic information basicInfo: media name, category, playback address, cover image, etc.
      2. Metadata metaData: size, duration, video stream information, audio stream information, etc.
      3. Information of the transcoding result transcodeInfo: addresses, video stream parameters, and audio stream parameters of various specifications generated by the file transcoding.
      4. Information of the animated image generating result animatedGraphicsInfo: information of an animated image (such as .gif) generated from a video.
      5. Information of a sampled screenshot sampleSnapshotInfo: information of a sampled screenshot of a video.
      6. Information of an image sprite imageSpriteInfo: information of an image sprite generated from a video.
      7. Information of a point-in-time screenshot snapshotByTimeOffsetInfo: information of a point-in-time screenshot of a video.
      8. Information of a timestamp keyFrameDescInfo: information of a timestamp configured for a video.
      9. Information of transcoding to adaptive bitrate streaming adaptiveDynamicStreamingInfo: specification, encryption type, muxing format, etc.
    Upper limit of returned results:
    • The Offset and Limit parameters determine the number of search results on one single page. Note: if both of them use the default value, this API will return up to 10 results.

    • Up to 5,000 search results can be returned, and excessive ones will not be displayed. If there are too many search results, you are recommended to use more filters to narrow down the search results.

    A maximum of 100 requests can be initiated per second for this API.
