Converting to double before the multiplication rather than after
avoids an integer overflow in some cases.

Prevent error condition in case sample_rate is unset or set to a negative
value. In particular, fix divide-by-zero error occurring in ffmpeg due to
sample_rate set to 0 in output_packet(), in code:
ist->next_pts += ((int64_t)AV_TIME_BASE * ist->st->codec->frame_size) /
ist->st->codec->sample_rate;
Fix trac ticket #324.

avfilter_draw_slice() is already called in the end_frame() callback,
this avoids multiple calls. This is done by adding a null draw_slice()
callback.
In particular fix crash occurring with -vf transpose=3,hflip, fix trac
issue #371.

There were multiple issues, for example might we have to re-run
the decompression when the size of the buffer increased,
we should always use a decompression buffer large enough for
the header (so we do not get stuck when the size is too small).

Sample is unfortunately not available, but it might be caused by
