Frequently Asked Questions

How to write a custom action?

See Write Custom Actions for instructions on creating custom actions.

How do I download only part of a recording?

For .mcap files, klein download can fetch only some topics or a time window. See Partial Download.

Should I compress my MCAP files?

Compress the chunks inside the file, never the whole file: .mcap.zst or .mcap.gz files cannot be uploaded. Compressed chunks make partial downloads by topic expensive. See MCAP Chunking and Compression.

Why is my file marked as Corrupted?

Its content does not match its file type, or it cannot be read, e.g. an .mcap from a recording that was cut off. Hover over the state icon for the reason. See File States.

klein login switches to a headless login when it finds no browser. See Headless Login.
