Since the duration is compared to the tfra durations/intervals which
are expressed in pts, calculate that here as well.

Reads the fragment duration from the trun sample data, rather than
assuming that there are no gaps. Creates much better playlists for our
inputs.

The input file may not have consistent start times, stream durations and
chunk durations. This patch at least removes negative durations that
make chromecast unhappy, and correctly sets starting time on chunks so
that the split (or .ismf) outputs match the manifest.

Previously, this could create files named "(null).ismf", if the -ismf
parameter is specified (before an input file name), but without
specifying any base name.

This is a non-standard file that maps the MSS segment names to offsets
in the ISMV file. This can be used to build a custom MSS streaming
server without splitting the ISMV into separate files.

This creates best-effort results from input that is missing stream

This allows storing the .ismv/.isma/.ismc files separately from
the .ism file on a server, without having to manually edit the
.ism file after generating it with the ismindex tool.

If the input file contains other tracks (non video/audio) that
aren't included in ismindex, the global file duration as returned
by libavformat might not be equal to the maximum of the duration
of the actual included tracks.
Signed-off-by: Martin Storsjö <martin@martin.st>

The stream duration is used for calculating the duration of the
last fragment easily without manually parsing anything else than
the mfra/tfra atoms. When the global file duration was used
previously, the duration of the last fragment could end up wrong
if the streams weren't equally long.

In Smooth Streaming, the fragments are addressed by time, and
the manifest only stores one list of time offests for all streams,
so all streams need to have identical fragment offsets. Warn if
this isn't the case, so that the user can fix the files instead of
getting failures at runtime when the fragments can't be found.
