Comment (by burek):

 Well if I'm wrong (and I've used named pipes a lot in the past and never
 had such issues like this one mentioned in this ticket) then the faq item
 might be wrong as well. Since it does exactly what I described here.

 Btw, such an example of a dead lock, that you offered, simply shouldn't
 happen in this scenario, since 2 outputs are completely independent (raw
 audio vs raw video) and if I'm not wrong, ffmpeg does that in separate
 threads, so that situation should never happen.

 Also, 1 process is using both pipes for write only and 2nd process uses it
 as read only. So that's also the indicator that such deadlock should never
 occur in theory, for this scenario.
