IVideoIndexer¶

Namespace: VideoCataloger

Type: Interface

VideoIndexer interface.

Definition¶

public interface IVideoIndexer

Methods¶

Method	Description
CaptureSingleFrame(long, double)	Capture an a frame at the provided time. This function will queue a capture of a given frame if a capture is in progress.
CaptureSingleFrameToFile(long, double, string)	Capture an a frame at the provided time to a jpeg file. This function will queue a capture of a given frame if a capture is in progress.
AddVideoFile(string, string, string, string)	Add a video file in the queue to be indexed.
AddFolder(string, bool, bool)	Scan a folder of videos in the queue to be indexed.
StartIndexing()	Start processing the index queue.
StopIndexing()	Request that indexing stops. The remaining queue is kept, so indexing can be resumed with StartIndexing.
SetIndexingCallbacks(IVideoIndexerCallbacks)	Set callback interface implementation
SetTranscription(long, string)	Set transcription from an srt file. If there already is a transcription for the video it will be replaced.

CaptureSingleFrame¶

Capture an a frame at the provided time. This function will queue a capture of a given frame if a capture is in progress.

void CaptureSingleFrame(long video_id, double current_video_play_pos)

Parameters:

Name	Type	Description
`video_id`	`Int64`	Id of video to capture from
`current_video_play_pos`	`Double`	Seconds from the start where we want to capture

CaptureSingleFrameToFile¶

Capture an a frame at the provided time to a jpeg file. This function will queue a capture of a given frame if a capture is in progress.

void CaptureSingleFrameToFile(long video_id, double current_video_play_pos, string output_file)

Parameters:

Name	Type	Description
`video_id`	`Int64`	Id of video to capture from
`current_video_play_pos`	`Double`	Seconds from the start where we want to capture
`output_file`	`String`	Path to where to save the file.

AddVideoFile¶

Add a video file in the queue to be indexed.

void AddVideoFile(string path, string title = "", string url = "", string desc = "")

Parameters:

Name	Type	Description
`path`	`String`	Path to the video file to be added. Please use windows paths and remember you need to use // to get a / in a C# string.
`title`	`String`	optional title of the video file
`url`	`String`	optional url for the video file.
`desc`	`String`	option desc for the videoe.

AddFolder¶

Scan a folder of videos in the queue to be indexed.

void AddFolder(string folder, bool include_subfolders, bool skip_added)

Parameters:

Name	Type	Description
`folder`	`String`	Path to the folder to scan.
`include_subfolders`	`Boolean`	Scan subfolders for videos.
`skip_added`	`Boolean`	Ignore videos already in the catalog.

StartIndexing¶

Start processing the index queue.

If a call to AddFolder or AddVideoFile is still scanning when you call this, the request is remembered and indexing starts as soon as that scan has finished. That means AddFolder followed directly by StartIndexing works as expected — you do not have to wait between the two calls.

void StartIndexing()

StopIndexing¶

Request that indexing stops. Videos that have already been indexed stay in the catalog and the remaining queue is kept, so indexing can be resumed with StartIndexing. Does nothing if indexing is not running.

void StopIndexing()

SetIndexingCallbacks¶

Set callback interface implementation

void SetIndexingCallbacks(IVideoIndexerCallbacks callbacks = null)

Parameters:

Name	Type	Description
`callbacks`	`VideoCataloger.IVideoIndexerCallbacks`	Object implementing the IVideoindexerCallbacks interface. Call with null to clear any previously set callbacks

SetTranscription¶

Set transcription from an srt file. If there already is a transcription for the video it will be replaced.

void SetTranscription(long video_id, string path)

Parameters:

Name	Type	Description
`video_id`	`Int64`	Id of video that will get the loaded transcript.
`path`	`String`	Path to the srt file to be used for transcription. Please use windows paths and remember you need to use // to get a / in a C# string.
