[Encode2mpeg-users] DVP642 A/V sync problem with ac3 5.1 audio

[JohnG <4p...@gm...>]

I would like to archive my DVDs for playback on a DVP642 hardware 
player.  I have had no success in preserving ac3 5.1 audio. 

This command I found in profile.html produces an avi file that plays 
back without any A/V sync problem on the DVP642.  Unfortunately,  it 
encodes the audio into mp3 format:

encode2mpeg -o movie dvd://1 -avionly -aid 128 -encode 3:2:2 -profile divxht

I have a multichannel sound system and mp3 is not going to satisfy the 
concept of archiving. 

I was hoping to preserve the ac3 5.1 audio.

Every attempt so far to preserve the 5.1 audio has resulted in an A/V 
sync problem where the video is delayed by about 2 seconds.  The 
playback starts out ok, but after about a minute the video delay is there.

After much trial and error, I extracted a chapter from the DVD that had 
much dialog.  The object was to be able to observe the A/V sync. 

mplayer dvd://1 -chapter 10-10 -v -dumpstream -dumpfile in.mpg

Then the following commands were tried and the results burned to a 
Verbatim DVD+RW and played back on the DVP642.  All experienced the 
video delay.  All of the files played ok with mplayer.

nice -n 9 encode2mpeg -o as621448 in.mpg -avionly -aid 128 -channels 6 
-encode 6:2:1,448 -profile aspl5

nice -n 9 encode2mpeg -o as631384 in.mpg -avionly -aid 128 -channels 6 
-encode 6:3:1,384 -profile aspl5

nice -n 9 encode2mpeg -o ht621448 in.mpg -avionly -aid 128 -channels 6

nice -n 9 encode2mpeg -o as022 in.mpg -avionly -aid 128 -encode 0:2:2 
-profile aspl5

nice -n 9 encode2mpeg -o as032 in.mpg -avionly -aid 128 -encode 0:3:2 
-profile aspl5

nice -n 9 encode2mpeg -o ht021 in.mpg -avionly -aid 128 -encode 0:2:1 
-profile divxht

nice -n 9 encode2mpeg -o ht031 in.mpg -avionly -aid 128 -encode 0:3:1 
-profile divxht

nice -n 9 encode2mpeg -o ht022 in.mpg -avionly -aid 128 -encode 0:2:2 
-profile divxht

nice -n 9 encode2mpeg -o ht032 in.mpg -avionly -aid 128 -encode 0:3:2 
-profile divxht

So, am I wasting my time on the DVP642(I can return it for a refund)? 

Is there a workable DVD player, a fix for encode2mpeg, or am I making a 
mistake of my own?

The command line you are using are supposed to work. But I don't remember
if I did extensive test with ac3 5.1 audio with the DVP 642.
I will try to reporduce your problem and see what's going on.
You will hear more in a couple of days.

I was not able to see the delay with my own encoding.

Please run the following command:
encode2mpeg -o as031 in.mpg -avionly -aid 128 -encode 0:3:1 -profile aspl5 -debug 7

Then compress and send to encode2mpeg at users.sourceforge.net the files as031.log and as031.debug.
I will probably also need to play myself as031.avi. Can you put it somewere where
I can download it?

Yes, I have sent a private link to your email.

The mplayer binaries I used were obtained from linuxpackages.net:

MPlayer-1.0pre7try2-i686-3jto.tgz

I included the file in the private link.

I have played your file as031.avi on my player and I didn't
observe any desync. I have played the audio with the stereo
conversion because at the moment my dolby 5.1 set is not
connected. Please play the avi on the DVP 642 using the 
stereo audio from the TV. I don't think it should make any
difference if you play as stereo or as 5.1 dolby digital,
but try just in case.
If you still have the delay when you play the audio as stereo,
then the problem may be with your DVP 642. I did install the 
last firmware available at the time I bought the player.
Version 0112. I you have still the original firmware may 
be an upgrade can solve the problem.

I played as031.avi using pcm out of the dvp632 like this: System, Audio, 
Digital, PCM. The dvp642 is connected to the Receiver via coaxial cable. 
The Receiver display indicated PCM instead of Dolby sound and played the 
file with good a/v sync. Thank you!

I did upgrade the firmware from 1223(year?) to 0603(2006).

The video still lags as before with digital audio. I understand this is 
the latest firmware. I hold out little hope that any more firmware will 
be released. At least I can rest assured that my archive is good and 
someday I may get a better hardware player than the dvp642.

Again, thank you for your help.

I have been trying to send this info since 2006-09-27. It keeps getting 
errors.

P.S. I have upgraded to encode2mpeg 6.0 and mplayer SVN and the problem 
persists.

I finally had the time to check your report. The problem exists, but it
seems to me more a mencoder issue. At the moment I don't have a 
solution. I will contact mplayer's developers and see if anybody can help.

[Encode2mpeg-users] Catching up 2 minutes on avi's

[Roger <ro...@br...>]

I'm trying to figure the behavior of -usespeed used to convert ntsc
speed avi's to pal DVDs. In a 44 min avi length I'll get 42 minutes in
DVD mpeg and the sound is slightly pitched up to sync with that. The avi
plays in 23.976 fps.

It will probably go unnoticed to most people but the ring of a phone and
musical stuff sound rancid.

encode2mpeg myth1.avi -o DVD-myth8 -n p -usespeed -a 3 -stdvid 7
-nosplit -mpegonly

As Gentoo threw out mplayer-1.0_pre7 before 0.6.0 shipped I needed to go
with -stdvid 7 in order to be able to mux. How would I do in order for
the .avi and .mpeg to play the same speed, please?

Regards,

Roger

That's exactly what usespeed is supposed to do. In order to not duplicate frames,
the avi is played/encoded at higher speed. This result in a shorter mpeg
with a little higher pitch.

Apart from not using usespeed :-), you can try the new PAL telecine 
capability (in Mpeg Mode) of encode2mpeg 0.6.0. If the avi is 23.976 fps,
use the options "-n p -vfr 1 -p" in your command line.

PAL telecined mpeg plays fine with mplayer, but I haven't tested them yet
with an hardware dvd player. If you do such test, please let me know the
results.
