Currently it always exits with an error when more than
one position is specified.

715129cdc4 avconv: Set audio filter time base to the sample rate
If the output frame size is smaller than the input sample rate,
and the input stream time base corresponds exactly to the input
frame size (getting input packet timestamps like 0, 1, 2, 3, 4 etc),
the output timestamps from the filter will be like
0, 1, 2, 3, 4, 4, 5 ..., leadning to non-monotone timestamps later.

A concrete example is input mp3 data having frame sizes of 1152
samples, transcoded to aac with 1024 sample frames.

By setting the audio filter time base to the sample rate, we will
get sensible timestamps for all output packets, regardless of
the ratio between the input and output frame sizes.

5db5169e46 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.

4f1500689d 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.
