I was pleased that Dinky implemented the --audio-only option because it can be can be useful for discussion programmes on a slow or metered connection. Is there any way to force it to 128kbit/s? I have just downloaded Sunday's Andrew Marr, b09w2zj2, with --tvmode=hvflow --audio-only. I got a bit rate 317kbit/s and a file nearly three times as large as I wanted.
