GoPro.GPMF

A low-level parser for GPMF telemetry data.

Documentation

parseGPMF :: ByteString -> Either String [(FourCC, [Value])]

Parse GPMF data from a telemetry stream. A successful return value contains a list of FourCC tagged value lists.

Note that the input is the telemetry stream itself, not the container that contains it.
