Protobuf

Read and write MCAP

If you’re starting from scratch, you can write code that allows you to write your Protobuf data to MCAP files and subsequently read your Protobuf data from your MCAP files.

The mcap GitHub repo includes the mcap-protobuf-support Python package to help you write an MCAP reader and writer for Protobuf.
