Mp4ff Versions Save

Added

• New TryDecodeMfro function
• New mp4ff-subslister tool replacing mp4ff-wvttlister. It supports wvtt and stpp
• File.UpdateSidx() to update or add a top level sidx box for a fragmented file
• mp4.DecStartSegmentOnMoof flag to make the Decoder interpret every moof as a new segment start, unless styp, sidx, or mfra boxes give that information.
• New example add-sidx shows how on can add a top-level sidx box to a fragmented file. It further has the option to remove unused encryption boxes, and to interpret each moof box as starting a new segment.

Fixed

• More robust check for mfro at the end of file
• GetTrex() return value
• Can now write PIFF uuid box that has previously been read
