Sorry, forget it. Just read up on it and the FLV format does not contain this information in the first place, so the bug report is invalid.

See TracTickets
for help on using tickets.
Packet duration in the demuxer is available only in very few formats, and without really knowing if FLV as a format has it, its not a value you should generally rely on being present.
