Having a separate section for audio encoders simplifies navigation
and is slightly more consistent with the rest of the manual.

This actually matches what av_get_double did earlier, the
0.0/0.0 division was intentional, for producing NAN.

Still keeping the check for the return value from
av_get_number, for clarity.

Some received packets can have size 0. The return value from
av_malloc(0) may be NULL, which is ok if the size was 0. On
OS X, however, the returned pointer is non-null but leads to
crashes when trying to free it.

Correct the name from "remove_logo" to "remove-logo".

Parenthesis are misplaced in calculation of max_time.

It's a duplicate of AVFormatContext.nb_streams.

Grow the file and stream list in opt_input_file() instead of creating it
all at once in transcode().  This is simpler and will be useful for
following commits.

AVStream.index stores the same thing.
