(auto)gordianknot <-> yamaha problems

[robert9]

Hi,

I have the following problem with the AutoGordianKnot and GordianKnot 0.35.0 programs.
I have a standalone divx-certified dvd player (Yamaha S550), which should accept files
written with the DivX 5.x encoder, in 'home theater' mode.
When I rip a film from a normal dvd (playing well on the player) to *.vob and convert
it using the GordianKnot program (both versions mentioned above) to an *.avi file (using
DivX, or XviD (the DivX Pro codec is on my sytem, and many other video/audio codecs), I
get an *.avi file which plays well from HD using the DivX player (2.6 from DivXNetworks).
Burned on a cd-disk (both on unfinished cd-rw and on finished cd-r disks, saved as data-
file) it plays equally well on the computer (with DivX-player).

BUT when I try to play the cd's on my Yamaha standalone, the film is stuttering in sound
and picture: it cannot be played!!

Avi-files that I made through converting mpeg2 files give the same problems.

Curious: other, earlier made *.avi files (with other windowsprograms) **do** play on the
Yamaha without the problems above!!
But in a unsatisfactory quality (pixeling); that's why I switched to the Yamaha and
to GordianKnot.

Can anybody tell me what I do wrong and which solution is possible??
I want to stop waisting cd-r discs...

Thanks,
rob

Hello, and welcome to the forum.

I've moved your thread to the Hardware Players forum, since your problem is not with encoding, but with playback on your device.

I took the time to look up the Yamaha DVD S550 at the Videohelp.com DVD Player Database. Reading through the comments, I found:

• There is a firmware upgrade available for download
• People are reporting widely varying experiences with the player -- manufacturing quality control may be an issue

I recommend downloading and installing the firmware upgrade; if that doesn't solve your problem, you may wish to consider returning the player for service or replacement.

Since your videos play just fine in your PC, I don't think your trouble is related to your brand of CD media or your CD burner.

Hi,

Thanks for the 'welcome'!

Want to tell you some more about my problem:
I made 3 codings using VirtualDubMod 1.5.10 from the *.vob file ripped
from a short dvd-film.

first one: in VDM I selected the codec 'divx 4 ;-) fast motion'
the next coding: I took the codec 'divx 5'
the third time I selected the codex 'XviD'

Thus I have 3 separate films with the same content.

After burning as data disc on a rw cd disk (Nero), I tried the three
films in my Yamaha S550:
the films using the divx4 and divx5 codec were playing successfully, but I could see quality of the divx4 encoded was not so good (more blocks in the picture).
The specimen encoded with the XviD codec was stuttering in sound and picture.

So IMHO there must be something other than the codec, e.g. the program GordianKnot, which creates the problems I mentioned in my first message.
So I would like to contact the GK writer about this, and as I saw he is acting in the GK part of the forum, that's why posting there could be more useful??

Reason to use GK instead of VDM is that VDM will not encode mpeg2 files.. :-(

DivX ;)

• I'm guessing you meant DivX 3.11 -- also called DivX ;) -- also called DivX SBC -- when you describe using a fast motion DivX. But that particular version has problems. Doom9 said in his old Codec FAQ:

  Is High motion better than Low motion?
  
  Definitely not. In low bitrates the high motion codec will look a bit better in action scenes but in low action scenes it will look terribly. Besides.. if you look closely at it you'll see a lot of compression errors even in high motion scenes.. check the WM7 test for more info - it has sample video clips and a lot of pictures. Despite rumors DivX high motion will rarely go beyond 1000KBit/s. Even DivX low motion will only use the full bitrate you set when it encounters a really demanding scene.

  Normally, one uses GK and Nandub to encode DivX 3.11, even though it has a "standard" VfW codec interface so that Vdub and VdubMod can use it -- the best practice is to use Nandub or GK with Nandub for encoding. See http://www.doom9.org/divx3-guides.htm for your choices with GK/Nandub for SBC encoding.

DivX 5:

• MPEG-4 standalone players have a series of restrictions which you may possibly violating -- I don't know, because I don't know any of your codec settings.
  
  Your Yamaha player is listed in the "DivX Certified" program for the Home Theater profile. As such, there are codec limitations for DivX -- including 3.11 SBC -- that must be obeyed in order to produce a video which is guaranteed to play properly.
  
  See http://www.divx.com/certified/technical.php for a brief overview of the various profiles, and their limitations and restrictions. For much more information on DivX profile settings, see http://www.divx.com/divx/divxpro/guides/

XviD

• Standalone players that can play DivX can also play XviD, with the same restrictions that players may have for DivX. Be sure to set your XviD settings properly.

If instead, you elect to use AutoGK for DivX and XviD encoding -- rather than VdubMod manually, or even GK manually -- it will encode your XviD and DivX files with the proper standalone player restrictions selected automatically.

As far as I'm able to determine the Yamaha DVD-S550 is based around MediaTek's MT1389FE chip-set, so it should be able to spin just about any variation of an Mpeg4 (ISO 14496) video stream in .AVI

Can you provide some file details of one of your problem encodes. You can do this by using a tool such as GSpot or Sigma's AVICheck: -
