Comment:

 I thought that {{{mplayer -dumpstream}}} has additional possibilities
 (skip audio or video which works when using it for dvb capture but this is
 unrelated to the dump logic) but this either never works or only for
 specific streams (real-netword?), so {{{aviocat}}} indeed works as
 expected (although it cannot output to a pipe afaict), is there
 documentation somewhere? I couldn't find it in the doc directory...

 Otoh, I wonder how to read a stream that takes an option? I will open a
 new ticket if I find a usecase.

 I don't think {{{-f data}}} does anything similar, it reports {{{data
 files have exactly one stream}}} here.
