Sorry, must have messed something up when running the tests locally. I will also check the warning.
New contributor here, I have been looking at this issue for years now so I thought I would try to contribute. https://trac.ffmpeg.org/ticket/3123 My plan is * Read the extra data needed to support ordered chapters * Add some data structure tracking external files * Add an option to search for external segment with related discovery logic * Implement reading and seeking through external segments Let me know if you have any feedback.
