I agree, it is just a workaround..  But it is better than before
svn-8465, where cur_dts was set to some random packet's dts that
happened to be parsed in av_find_stream_info().

Do you think it is worth it to work more on this and backtrack the
durations with all the ordering issues?

Agreed, too -- but what output timestamps should be generated in that
case?  I believe this is the same or at least a similar problem I
reported two weeks ago with negative timestamps occurring..
