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.

Without this cast, the BE_32() expression is sign extended when
assigned to an uint64_t, since the uint8_t|uint8_t expression
is promoted to an int.
Also avoid undefined behaviour when left shifting an uint8_t
by 24 by casting it to an uint32_t explicitly before shifting.
Based on a patch by Michael Niedermayer.

These variables are assigned the return values of ftello, which
returns an off_t, which is a signed type. On errors, ftello returns
-1, thus make sure this error return value can be stored properly.

qt-faststart doesn't use the normal libav headers at all since
it's supposed to be a completely standalone tool, so we implement
the macro locally in this file.

Copying data in chunks of 1 KB is a little wasteful.
64 KB should still easily fit on the stack, so there's no need
to allocate it dynamically.

This avoids the caller having to calculate the byte rate if wanting
to push a file in a rate resembling realtime.

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.

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.

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

The tool nowadays supports more than one track per file,
this makes reading the code slightly less confusing.

It does not help as an abstraction and adds dsputil dependencies.

The missing headers are required for errno and for strerror.
This fixes building of this tool on mingw32ce.

PATH_MAX is not necessarily available on all systems, e.g. it's
normally not available on MSVC, and is not guaranteed to defined
on a POSIX system either.

This takes care of null-terminating the buffer if it is too small,
which wasn't handled properly before.

Also change the snprintf size to use the full buffer, since
snprintf always null-terminates the buffer.

The Windows SDK in MSVC doesn't have mkdir, only _mkdir, and
MSDN says one should include direct.h to use it.

This tool uses lavfi internal symbols not accessible in shared
libraries. TESTPROGS are linked statically to allow them use of
library internals not normally exported.

tools/graph2dot.c:85: warning: format ‘%lld’ expects type ‘long long int’, but argument 4 has type ‘int’

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.

Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

Sleep (which is defined in winbase.h and not in the standard
