Functions

CreateStream

 absl 
 :: 
 Status 
  
 CreateStream 
 ( 
  
 const 
  
  ServiceConnectionOptions 
 
  
 & 
  
 options 
 , 
  
 absl 
 :: 
 string_view 
  
 stream_id 
 )

Creates a new stream resource with id stream_id .

Details

Parameters

`option`	Connection options.
`stream_id`	The id of the stream to connect to.

Returns

OK on success. Otherwise the error indicating the cause.

DeleteStream

 absl 
 :: 
 Status 
  
 DeleteStream 
 ( 
  
 const 
  
  ServiceConnectionOptions 
 
  
 & 
  
 options 
 , 
  
 absl 
 :: 
 string_view 
  
 stream_id 
 )

Deletes the stream with id stream_id .

FromPacket

 absl 
 :: 
 StatusOr 
 < 
  
 T 
  
 > 
  
 FromPacket 
 ( 
  
 Packet 
  
 p 
 )

FromPacket attempts to unmarshal a Packet into a desired C++ Type.

An error code will be returned if p cannot be extracted as the requested C++ type.

IngestMp4

 absl 
 :: 
 Status 
  
 IngestMp4 
 ( 
  
 const 
  
  ServiceConnectionOptions 
 
  
 & 
  
 options 
 , 
  
 absl 
 :: 
 string_view 
  
 stream_id 
 , 
  
 absl 
 :: 
 string_view 
  
 file_name 
 )

Ingests an MP4 video file on the local file system named file_name into a stream of id stream_id .

This call blocks until the file is fully ingested.

The file is ingested at the rate of its playback. For example, if the playback duration of the video is 1 minute, then this function will take 1 minute to complete.

Returns OK on success; otherwise, an error message telling why the ingestion could not complete successfully.

IngestRtsp

 absl 
 :: 
 Status 
  
 IngestRtsp 
 ( 
  
 const 
  
  ServiceConnectionOptions 
 
  
 & 
  
 options 
 , 
  
 absl 
 :: 
 string_view 
  
 stream_id 
 , 
  
 absl 
 :: 
 string_view 
  
 rtsp_url 
 )

Ingests an RTSP camera endpoint rtsp_url into a stream of id stream_id .

This call blocks and ingests the RTSP feed indefinitely. It may complete if the RTSP feed reaches the end, or is otherwise terminated for any reason.

Returns OK on success; otherwise, an error message telling why the ingestion could not complete successfully.

ToPacket

 absl 
 :: 
 StatusOr 
 < 
  
 Packet 
  
 > 
  
 ToPacket 
 ( 
  
 T 
  
 && 
  
 t 
 )

ToPacket marshals an object of C++ type T into a Packet .

The set of possible C++ types that can be marshalled are listed in visionai/streams/packet/packet_codecs/codec_selector.h
