Using a linked list had very much overhead (the pointer to the next
entry increased the size of the index entry struct from 16 to 24 bytes,
not to mention the overhead of having separate allocations), so it is
better to (re)allocate a continuous array for the index.
av_fast_realloc_array() is used
This is an array-equivalent of av_fast_realloc(). Its advantages
compared to using av_fast_realloc() for allocating arrays are as
follows:
a) It performs its own overflow checks for the multiplication that is
implicit in array allocations. (And it only needs to perform these
checks (as well as the
Currently, the Matroska muxer reallocates its array of index entries
each time another entry is added. This is bad performance-wise,
especially on Windows where reallocations are slow. This is solved
by switching to av_fast_realloc_array() which ensures that actual
reallocations will happen only se
instead of av_fast_realloc() for allocating an array. It has the
advantage of doing it's own overflow checks and does not overallocate
unnecessarily: It allocates exactly one element if one element is
desired. This is advantageous for CueTrackPositions: While it is
allowed (and supported) to have m

I do not agree with that. size_t is the correct type for that use, and
therefore should be the cho
