++This build of ffmpeg includes NetBSD-specific patches that change the
++video-grabbing semantics. Recording from bktr(4) can be controlled via the
++following environment variables:
++.PP
++.RS
++.B BKTR_DEV
++(0\-4): which of the devices on the bktr should provide the signal (tuner,
++video-in,...)
++.PP
++.B BKTR_FORMAT
++(1\-6): TV format, 1 PAL 2 NTSC 3 SECAM 4 PALN 5 PALM 6 NTSCJ
++.PP
++.B BKTR_FREQUENCY
++(float): frequency to which the tuner should be set.
++.PP
++.B BKTR_CHANNEL
++(int): channel to which the tuner should be set, overrides BKTR_FREQUENCY
++.RE
++.PP
++If you set the channel or frequency with a different program such as xawtv
++or fxtv you might not get audio; try to use the environment variables in
++that case. Do not forget to set the following mixerctl variables to useful
++values:
++.PP
++.RS
++record.source=line
++.PP
++record.volume=255,255
++.PP
++inputs.line=255,255
++.RE
++.PP
++One possible command line would then be:
++.PP
++ffmpeg -y -intra -tvstd pal -vcodec mpeg2video -s 768x576 -b 9600 -ab 128 -ad
