Based on a posting from a number of months ago, I found the
method to create a video DVD that will play on a home DVD player.
Now, what options to ffmpeg and/or dvdauthor do I need in order
to enable scan-forward/reverse? Googling has not turned up a
solution. I have tried several combinations of options, but they
all show an odd-looking icon when I try to use the
scan-forward/reverse buttons. Here are the two examples I have
tried:

($gop is 15 or 18)

ffmpeg -i $inputfile -y -target ntsc-dvd -threads 2 -mbd rd -trellis 2 \
-cmp 2 -subcmp 2 -g $gop -pass 1 -an -f rawvideo -y /dev/null

ffmpeg -i $inputfile -y -target ntsc-dvd -threads 2 -mbd rd -trellis 2 \
-cmp 2 -subcmp 2 -g $gop -pass 2 $tmpfile

or

($bitrate is 3750000, $bufsize is 1835k)

ffmpeg -i $inputfile -y -target ntsc-dvd -threads 2 -mbd rd -trellis 2 \
-cmp 2 -subcmp 2 -b $bitrate -minrate $bitrate -maxrate $bitrate \
-bufsize $bufsize -g $gop \
-pass 1 -an -f rawvideo /dev/null

ffmpeg -i $inputfile -y -target ntsc-dvd -threads 2 -mbd rd -trellis 2 \
-cmp 2 -subcmp 2 -b $bitrate -minrate $bitrate -maxrate $bitrate \
-bufsize $bufsize -g $gop \
-pass 2 $tmpfile

followed by

dvdauthor --title -o $tmpdir -f $tmpfile
dvdauthor -o $tmpdir -T
mkisofs -o $isofile $tmpdir
growisofs -dvd-compat -Z /dev/cdwriter=$isofile

Suggestions?

Thanks,
