avconv: multithreaded demuxing.
...
When there are multiple input files, run demuxing for each input file in
a separate thread, so reading packets does not block.
This is useful for achieving low latency when reading from multiple
(possibly slow) input streams.

avconv: use lrint() for rounding double timestamps
...
Converting the double to float for lrintf() loses precision when
the value is not exactly representable as a single-precision float.
Apart from being inaccurate, this causes discrepancies in some
configurations due to differences in rounding.
Note that the changed timestamp in the vc1-ism test is a bogus,
made-up value.
