 command succeeds.  File is playable (with audio) by ffplay, but has "no
 audio" in either VLC or Windows Media Player.

 If I dump it to out.avi, the resultant file has "no video" in WMP, but
 does have audio, and plays fine in VLC.  Or should I file that as a
 separate ticket?

 MediaInfo seems to reveal it having an audio track ok.
