Reading option: -b:a is -b:a' ... matched as option 'b' (video bitrate (please use -b:v)) with argument '128k'

[natsmith52]

-report:
Using -b:a to set the audio; is reported to match to the video -b; even though is is actually being use correctly by the audio codec. Output is OK.
-ab no longer appears to work; but many examples still show it.
