If you don't specify an encoder (explicitly), the
default encoder for the container you specified
(either explicitly with -f or implicitly via the
output file name) is chosen, not the "best" encoder.
If the documentation states something else, it should
Note that we did change the default encoder for some
containers in the past, there is no guarantee that we
will not change it again.
This is ticket #1325 that should probably be closed
as explained by Reimar there.
Please consider reading http://ffmpeg.org/contact.html
