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.

Note:
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.
