Record Video Node

RecordVideo host node is used for recording ImgFrames and EncodedFrames to video and metadata files. Video is recorded using the mp4 format and metadata is recorded with mcap using protobuf serialization.

How to place it

Python

Python
1with dai.Pipeline() as pipeline:
2    record = pipeline.create(dai.node.RecordVideo)

C++

C++
1dai::Pipeline pipeline;
2auto record = pipeline.create<dai::node::RecordVideo>();

Inputs and Outputs

Usage

Python

Python
1with dai.Pipeline() as pipeline:
2    record = pipeline.create(dai.node.RecordVideo)
3    record.setRecordVideoFile("video.mp4")
4    record.setRecordMetadataFile("metadata.mcap")

C++

C++
1dai::Pipeline pipeline;
2auto record = pipeline.create<dai::node::RecordVideo>();
3record->setRecordVideoFile("video.mp4");
4record->setRecordMetadataFile("metadata.mcap");
