ce611a27be Change rounding of the horizontal DWT to match the vertical one.
This allows some simplifications and optimizations and should
not have any effect on quality.

3a9f44d5d5 and of course the unneeded double subtractions were blindly put in the
mmx code
this also makes the affected code 4% faster

89da5781a1 Call av_find_stream_info() immediately after opening an input file.
Needed to avoid reading the same TS two times at the beginning of the
file (whic resulted in an "error, non monotone timestamps..." when
streaming RTP from a file)

d6a0906ad1 When looking for the last packet in each
stream, so as to calculate the duration, don't stop
as soon as all streams have seen at least one packet.
Otherwise the duration will be shorter than it
should be.  We must keep reading to the end-of-file.

bf494092b0 There is no guarantee that every stream will
have a start_time found (though it is likely),
so check that the start_time is defined before
calculating a duration.
