#5437 — What is needed to make a DVD (from VHS) do trick play?

What is it that is needed to make a home-burned DVD (digitized
from old home-movie VHS tapes) capable of trick-play?

I have Googled for answers until my fingers are numb from typing
search terms.  According to the literature, the DSI part of the
NAV packets are what facilitates trick-play, and dvdauthor will
fill in the contents of those packets if it has raw packets from
"mplex -f 8".

Digitizing is done by a Hauppage HVR-1950, and I have found the
v4l2-ctl option to set stream_type to 3, which is allegedly
DVD-compatible.  Using dvdauthor yields a one-VOB DVD that plays
fine at 1X forward speed--with or without using ffmpeg to
separate the audio and video and "mplex -f 8 ..." to put them
back together (modulo synchronization).  According to mpeg2desc,
both with and without the ffmpeg-split-mplex-recombine routine,
the GOPs are all of length 18, the same as a non-encrypted
commercial disc that does trick-play, and the NAV packets with
their DSI and PCI packets are present.  However, the hardware
player still refuses to go backwards or faster forward than 1X.
(It will go slower than 1X, IIRC.)  All programs are the versions
that came with Mageia 1.

Do I have to put some button definitions in a menu in order to
enable trick-play?

Is there some other incantation that must be used in the pipeline
through ffmpeg, mplex, and dvdauthor to enable it?

Any suggestions?

Thanks.

I have no experience with this hardware. Will it be possible to
make just an *.avi file from your video ? From this point on I could
provide some premade script to transform latter to a DVD.

It's trivial to get a MPEG file from the card: just set the
options via v4l2-ctl and cat from /dev/video1 (webcam is video0)
to a file.  It's also easy to produce a DVD-compatible ISO using
dvdauthor and a couple other programs.  The problem is that the
resulting DVDs to date do not do trick-play.  Would your script
have whatever is required to make a DVD that does trick-play?  If
so, could you post an example.

Thanks.

(Trick-play means going forward or backward faster than 1X.)

My video do it on my player. I have never seen a problem here.
I convert the *.mpg to *.iso as described here:

#!/bin/bash
#
#  MPG mit Kapitelmarken auf DVD bringen
#
# DVD-spezifischen Dateien und Ordner erstellen:
dvdauthor -o ./dvd_$1/ -t -c 
0,0:3:0,0:6:0,0:9:0,0:12:0,0:15:0,0:18:0,0:21:0,0:24:0,0:27:0,0:30:0,0:33:0,0:36:0,0:39:0,0:42:0,0:45:0,0:48:0,0:51:0,0:54:0,0:57:0,1:00:0,1:03:0,1:06:0,1:09:0,1:12:0,1:15:0,1:18:0,1:21:0,1:24:0,1:27:0,1:30:0,1:33:0,1:36:0,1:39:0,1:42:0,1:45:0,1:48:0,1:51:0,1:54:0,1:57:0,2:00:0,2:03:0,2:06:0,2:09:0,2:12:0,2:15:0,2:18:0,2:21:0,2:24:0,2:27:0,2:30:0,2:33:0,2:36:0,2:39:0,2:42:0,2:45:0,2:48:0,2:51:0,2:54:0,2:57:0,3:00:0  
-v 720x576+pal+4:3 -a mp2+de ./$1.mpg ;

dvdauthor -o ./dvd_$1/ -T ;
#
# nur das ISO machen :
mkisofs -dvd-video -o ./$1.iso ./dvd_$1/ ;

Just try and tell me the result.

Thank you very much.  Putting chapter markers every three minutes
is a very clever idea.  I'll try it at my earliest opportunity.

This is the advantage against (S)VCD to have those.
Thanks a lot that I could help you.

If you could find out an uncomplicated way in Linux to do the same in
an (S)VCD as well please send me an e-mail !

Bingo!!!  For some odd reason I don't understand, adding chapter
markers to a DVD VOB appears to make fast search forward and
backward work.  If chapter markers are what dvdauthor wants,
that's what it will get.

I'd love to be able to help with the (S)VCD issues, but that's
well over my present capabilities.

Thank you!
