[FFmpeg-user] Piping output of ffmpeg into ffmbc

Fri Aug 19 18:17:28 EEST 2016

Erik,
I was specifically thinking of fast import. I haven't been able to get
ffmpeg to create media for fast import, thats why i'm using ffmbc. Am I
correct in understanding that for fast import ffmpeg will not work? That is
what i have read and all my experiments with ffmpeg to create media for
fast import have failed.

This is the first time i am trying to pipe the output of ffmpeg and i
thought maybe there was something wrong with my command that was causing
the error. I guess this is not the case and i'll just have to experiment.
Thanks.

Keith
