When flushing the encoder, we now need to provide non-null buffer
parameters for everything, even if they are unused.
The encoderDelay parameter has been replaced by two, nDelay and
nDelayCore.

Entries are always at least 8 bytes per the parsing code, so if we
see an impossible entry count avoid massive allocations. This is
similar to an existing check in mov_read_stsc().
Since ff_mov_read_stsd_entries() does eof checks, an alternative
approach could be to clamp the entry count to atom.size / 8.
