Classes

ApiExifGpsMetadata

GPS coordinates and related tags extracted from image EXIF data. Fields are populated on a best-effort basis and may be empty when absent from the source file.

ApiExifMetadata

Image EXIF metadata. Fields are populated on a best-effort basis and may be empty when absent from the source file.

ApiKeyframe

A single extracted scene-change keyframe.

ApiMediaMetadata

Audio/video container and per-stream metadata. Fields are populated on a best-effort basis and may be empty when absent from the source file.

ApiMediaStream

A single audio or video stream within a media file.

ApiOfficeMetadata

MS Office document metadata. Some fields apply only to specific document types (e.g. Slides for PowerPoint, Words and Pages for Word).

ApiPdfMetadata

PDF document metadata.

ApiStructuredTranscript

A transcript, split into segments.

ApiTranscriptSegment

A contiguous span of transcribed speech. The span covered by a segment depends on the requested TimestampLevel.

ContentApiV2Error

Reason a transcript job failed. Returned in the GetTranscriptAsyncCheckResult.Failed variant. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response). Callers should branch on the variant.

ContentApiV2Error.IsAFolderError

The target is a folder, not a file.

ContentApiV2Error.LimitExceededError

A resource limit was exceeded while producing the result.

ContentApiV2Error.LinkDownloadDisabledError

FileIdOrUrl.Url referenced a Dropbox shared link whose owner has disabled downloads.

ContentApiV2Error.MediaDurationError

The audio to transcribe is longer than the supported maximum.

ContentApiV2Error.NoAudioError

The file has no audio track, or no audio content could be detected in it.

ContentApiV2Error.NotFoundError

The referenced file does not exist or is not accessible.

ContentApiV2Error.Other

The other object

ContentApiV2Error.ServerError

An unexpected, typically transient, server-side failure. The string is a human-readable message; retrying with backoff may succeed.

ContentApiV2Error.SharedLinkPasswordProtected

FileIdOrUrl.Url referenced a password-protected Dropbox shared link. Riviera cannot supply the password, so such links cannot be transcribed.

ContentApiV2Error.UserError

The request could not be processed as supplied (a problem with the caller's input). The string is a human-readable message; retrying the same request will not help.

DownloadTransformOutputArgs

Arguments for `download_transform_output`.

DownloadTransformOutputResult

Describes the bytes in the response body. Returned in the `Dropbox-API-Result` header.

ExtractApiV2Error

Reason an extraction job failed. Returned in the `failed` variant of `ExtractAsyncCheckResult`. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response). Callers should branch on the variant.

ExtractApiV2Error.ConversionFailureError

The source file was readable but could not be processed, for example because it is corrupt.

ExtractApiV2Error.IsAFolderError

The target is a folder, not a file.

ExtractApiV2Error.LimitExceededError

A resource limit was exceeded: the source file is larger than the requested `extract_type` accepts, or the result would be too large to return. For `keyframes`, raise `scene_change_threshold` or turn off `include_images`; for `markdown`, turn off `embed_images`.

ExtractApiV2Error.LinkDownloadDisabledError

`FileIdOrUrl.url` referenced a Dropbox shared link whose owner has disabled downloads.

ExtractApiV2Error.NoAudioError

`transcript` only: the source file has no audio track.

ExtractApiV2Error.NotFoundError

ExtractApiV2Error.UnsupportedFormatError

The source file is not in a format the requested `extract_type` supports.

ExtractApiV2Error.UserError

The request could not be processed as supplied (a problem with the caller's input), for example an out-of-range option. The string is a human-readable message; retrying the same request will not help.

ExtractArgs

Arguments for the asynchronous `extract_async` route. Exactly one of `file_id`, `path`, or `url` must be supplied via `file_id_or_url` to identify the source file, and `extract_type` must say what to extract from it.

The transcript. Its segments are empty when no speech is detected.

ExtractType

What to extract from the source file, with that extraction's options. Exactly one variant must be set. Every variant carries an options message, so always send the object form -- for example `{".tag": "text"}` -- rather than a bare tag string. Option fields may be omitted to take their defaults.

ExtractType.Keyframes

Detect scene changes in a video and return one keyframe per scene. Supported formats: .3gp, .3gpp, .3gpp2, .asf, .avi, .dv, .flv, .m2t, .m2ts, .m4v, .mkv, .mov, .mp4, .mpeg, .mpg, .mts, .mxf, .oggtheora, .ogv, .rm, .ts, .vob, .webm, .wmv. At most 10 GB.

A file with no audio track fails with `no_audio_error`.

FileIdOrUrl

The file id or url object

The other object

FileIdOrUrl.Path

An absolute Dropbox path, e.g. "/folder/example.pdf".

FileIdOrUrl.Url

Either a Dropbox shared link (www.dropbox.com) or an internet-accessible URL pointing to a supported file. - Dropbox shared links are resolved internally using the caller's authenticated identity and the link's visibility / download settings. They therefore require an authenticated user context; requests made with app auth alone are rejected. Password-protected links and links with downloads disabled are rejected as well. - Other URLs are fetched by Dropbox's servers, so they must be reachable from the public internet -- not only from the calling application's network -- and must point at a supported file extension.

ImageOptions

Options for `TransformType.image` and `TransformType.image_pdf`. Supplying this message with any other transform type fails with `invalid_options_error`.

KeyframesExtractOptions

Options for `ExtractType.keyframes`.

KeyframesExtractionApiV2Error

Reason a keyframe extraction job failed. Returned in the `failed` variant of `GetKeyframesAsyncCheckResult`. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response). Callers should branch on the variant.

KeyframesExtractionApiV2Error.ConversionFailureError

The source file was readable but could not be processed, for example because it is corrupt.

KeyframesExtractionApiV2Error.IsAFolderError

The target is a folder, not a file.

MarkdownExtractOptions

Options for `ExtractType.markdown`.

MediaDurationError

The media duration error object

MetadataExtractionApiV2Error

Reason a metadata extraction job failed. Returned in the GetMetadataAsyncCheckResult.Failed variant. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response). Callers should branch on the variant.

MetadataExtractionApiV2Error.ConversionFailureError

The source file was readable but its metadata could not be extracted, for example because the file is corrupt.

The source file is not in a format this route can extract metadata from.

MetadataExtractionApiV2Error.UserError

The request could not be processed as supplied (a problem with the caller's input) -- for example an unsupported file format or a file over the size limit for its metadata kind. The string is a human-readable message; retrying the same request will not help.

MetadataType

Which metadata variant is populated in a GetMetadataResult, derived from the file type.

MetadataType.MetadataTypeExif

MetadataUnion.Exif is populated.

MetadataType.MetadataTypeMedia

MetadataUnion.Media is populated.

MetadataType.MetadataTypeOffice

MetadataUnion.Office is populated.

MetadataType.MetadataTypePdf

MetadataUnion.Pdf is populated.

MetadataType.MetadataTypeUnknown

No metadata kind applies to the file, so no variant of Metadata is populated. Riviera only produces metadata for the formats listed on GetMetadataAsyncAsync(GetMetadataArgs) GetMetadataAsyncAsync(GetMetadataArgs); a request for any other file normally fails with MetadataExtractionApiV2Error.UserError rather than completing with this value. An app that does receive it should treat the file as having no extractable metadata; retrying will not change the outcome.

MetadataType.Other

The other object

MetadataUnion

The extracted metadata. Exactly one variant is populated, corresponding to MetadataType.

OcrExtractionApiV2Error

Reason an OCR extraction job failed. Returned in the `failed` variant of `GetOcrAsyncCheckResult`. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response).

TextExtractionApiV2Error

Reason a text extraction job failed. Returned in the `failed` variant of `GetTextAsyncCheckResult`. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response). Callers should branch on the variant.

TextExtractionApiV2Error.ConversionFailureError

The source file was readable but could not be processed, for example because it is corrupt.

TextExtractionApiV2Error.IsAFolderError

The target is a folder, not a file.

The source file is not in a format this route supports.

TextExtractionApiV2Error.UserError

The request could not be processed as supplied (a problem with the caller's input). The string is a human-readable message; retrying the same request will not help.

ThumbnailFormat

The encoding of the produced image. These match `files/get_thumbnail`'s formats: JPEG is the better choice for photographs, PNG for screenshots, line art, and anything with sharp text edges or transparency.

ThumbnailFormat.Jpeg

Lossy JPEG. The default, and the right choice for photographic sources.

ThumbnailFormat.Other

The other object

ThumbnailFormat.Png

Lossless PNG, with alpha preserved.

ThumbnailFormat.Webp

WebP, which compresses better than either JPEG or PNG at comparable quality but is not readable by every consumer.

ThumbnailMode.Original

Don't resize the image at all.

ThumbnailMode.Other

The other object

ThumbnailMode.Strict

Scale down the image to fit within the given size.

ThumbnailOptions

Options for `TransformType.thumbnail`. Supplying this message with any other transform type fails with `invalid_options_error`.

ThumbnailSize

The size of the thumbnail to produce. These are the same named size buckets `files/get_thumbnail` supports, with the same meanings; arbitrary pixel dimensions are not accepted.

ThumbnailSize.Other

The other object

ThumbnailSize.W1024h768

1024 by 768 px.

TimestampLevel.Word

One segment per word, useful for fine-grained alignment such as captioning or highlight-as-you-listen experiences.

TranscriptExtractOptions

Options for `ExtractType.transcript`.

TransformApiV2Error

Reason a transform job failed. Returned in the `failed` variant of `GetTransformAsyncCheckResult`, and by `download_transform_output`. This is a semantic error union: the HTTP status of the poll request itself is unaffected (a poll that surfaces a failed job is still a normal successful poll response). Callers should branch on the variant.

TransformApiV2Error.ConversionFailureError

The source file was readable but could not be converted, for example because it is corrupt.

TransformApiV2Error.ExpiredHandleError

The `output_handle` presented to `download_transform_output` has passed its `TransformOutput.expires_ts`. Request the transform again to get a fresh handle. Only `download_transform_output` produces this; a poll never does.

TransformApiV2Error.InvalidOptionsError

`transform_type` was missing, or the supplied options did not match the requested transform type, or an option was out of range. The request is malformed; fix it rather than retrying it.

TransformApiV2Error.IsAFolderError

The target is a folder, not a file.

TransformApiV2Error.LimitExceededError

A resource limit was exceeded while producing the result -- for example the source file is larger than the requested transform accepts.

TransformApiV2Error.LinkDownloadDisabledError

`FileIdOrUrl.url` referenced a Dropbox shared link whose owner has disabled downloads.

TransformApiV2Error.NotFoundError

The referenced file does not exist or is not accessible.

TransformApiV2Error.Other

The other object

TransformApiV2Error.ServerError

An unexpected, typically transient, server-side failure. The string is a human-readable message; retrying with backoff may succeed.

TransformApiV2Error.SharedLinkPasswordProtected

`FileIdOrUrl.url` referenced a password-protected Dropbox shared link. Riviera cannot supply the password, so such links cannot be transformed.

TransformApiV2Error.UnsupportedFormatError

The source file is not in a format the requested `transform_type` can convert.

TransformApiV2Error.UserError

The request could not be processed as supplied (a problem with the caller's input). The string is a human-readable message; retrying the same request will not help.

TransformArgs

Arguments for the asynchronous `get_transform_async` route. Exactly one of `file_id`, `path`, or `url` must be supplied via `file_id_or_url` to identify the source file, and exactly one variant of `transform_type` must be set to say what to produce from it. At most one options message may be set, and it must be the one belonging to the requested `transform_type`. Options that belong to a different transform type are rejected with `invalid_options_error` rather than ignored, so that a request whose parameters were misassembled fails visibly instead of quietly producing the wrong output.

TransformOutput

A completed transform: a handle for retrieving the produced bytes, plus enough metadata to decide whether to retrieve them. The bytes themselves are deliberately not carried here. A completed async result is persisted, so it is bounded by a row-size limit well below the size of a typical converted document -- an inline payload would fail for exactly the large documents this route exists to convert. The transform therefore completes by caching its output and handing back `output_handle`, which `download_transform_output` exchanges for the bytes.

TransformType

Which derived file to produce from the source file. Unlike the other Riviera content routes, which each expose one capability, `get_transform_async` is a single route over many conversions: the caller names the source file and the output it wants, and the service picks the conversion pipeline. Exactly one variant must be set; a request with none set fails with `invalid_options_error`.

TransformType.Html

Convert the source document to HTML. Supported for spreadsheets only, where HTML preserves the sheet layout that a PDF rendering flattens.

TransformType.Image

Re-encode the source as a web-safe raster image (JPEG or PNG). This is the transform to use to normalize formats a browser cannot display directly -- HEIC, camera RAW, PSD, SVG -- and to render a single page of a document as an image. Formats a browser can already display, such as JPEG and PNG, are not accepted; use `thumbnail` to resize or re-encode those. Configured by `TransformArgs.image`.

TransformType.ImagePdf

Render the source as a page image by way of a PDF conversion, rather than by whichever image pipeline the source format would otherwise use. Prefer `image` unless you specifically need the PDF-rendered result; the two differ for formats that have a native image pipeline of their own (ebooks, for example). Configured by `TransformArgs.image`.

TransformType.Other

The other object

TransformType.Pdf

Convert the source document to PDF. Supported for word-processing, presentation, and spreadsheet documents; images are not accepted.

TransformType.Thumbnail

Produce a resized thumbnail of the source at one of the supported sizes. Configured by `TransformArgs.thumbnail`.

TransformType.VideoFrame

Extract a single frame from a video as a still image. Configured by `TransformArgs.video_frame`. This produces one frame at one requested offset. To get the set of scene-change keyframes across a whole video, use `get_keyframes_async`, which returns every detected frame with its timestamp and scene score.

VideoFrameOptions

Options for `TransformType.video_frame`. Supplying this message with any other transform type fails with `invalid_options_error`.
