FFmpeg maintainers ================== Below is a list of the people maintaining different parts of the FFmpeg code. Please try to keep entries where you are the maintainer up to date! Names in () mean that the maintainer currently has no time to maintain the code. A (CC
) after the name means that the maintainer prefers to be CC-ed on patches and related discussions.
