In BDAV's M2TS there are .clpi files, in AVCHD the same files are labeled as .CPI. As i understand, some sort of metadata is written into these files. The question is twofold:
- What metadata exists in these files? (both 'by the standard' and 'de facto', if there are differences)
- Are there any free/libre/open-source software tools that are able to extract this metadata from them?
An example of such a file is here.
