Fox & Hound DVD bogged in a cell loop...

Post by Wagonfixin » Fri Dec 31, 2010 4:53 am

DVD is Disney's "The Fox and the Hound" (25th Anniversary).

Seems to bog down in a loop during cell detection....

Code: Select all

MakeMKV v1.6.3 linux(x64-release) started
Debug logging enabled, log will be saved as /tmp/MakeMKV_log.txt

Operation successfully completed
Saving 1 titles into directory /tmp/THE_FOX_AND_THE_HOUND
The above loop/skipping went on for well over 11mins (MakeMKV GUI seemed to estimate this time/duration correctly) with Cell-7 spinning back-n-forth between VOBU 6195 & 12749, then same cell; between VOBU 27745 & 34480, and lastly; same cell between VOBU 52043 & 58636.

Any idea if this behaviour is normal ? (of all the dvd's archived by MakeMKV, this is the only one to spin in circles like this). The MKV seems to be fine.

I can post VTS/IFO's if it'll help...

Tried this same DVD/drive combination with the current DVDFab, "structure recognition" took ~1min...

Hi!
The MKV seems to be fine.
This is really all that counts; >}
The above loop/skipping went on for well over 11mins
Tried this same DVD/drive combination with the current DVDFab, "structure recognition" took ~1min...
You're comparing the proverbial apples and oranges - How long did it take DVDFab to do the entire rip, conversion to .MKV (if it has that capability), and write to hard drive? How long did it take MakeMKV to do the same complete procedures?

Indeed a working MKV is the measure of success !! I thought a little data could improve MakeMKV's "detection algorithm".
You're comparing the proverbial apples and oranges -
Not really, both applications traverse thru similar DVD content/encoding to determine how to unwind the frames/data into un-encoded streams.

Gimme a coupla mins, and I'll have some real duration data to compare.

Times were measured on the same machine/HDD/DVD/DVD-drive/DVD-data (note that DVDFab may actually be faster in a native MS Windows session as the DVDFab times were collected under Linux's WINE).

Time was collected for each application in 2 distinct stages:
1) Initial DVD analysis
2) DVD data copy

MakeMKV v2.63:

Code: Select all

00:00 - Detection start
11:24 - Detection complete; ready to write data
-------
11:24 - MakeMKV's time to complete "detection/analysis"

00:00 - Start of data copy
08:42 - Data copy to HDD completed
-------
08:42 - MakeMKV's time to complete "data copy"
20:06 - MakeMKV's total time to transfer title data to DVD

DVDFab v8.0.6.6

Code: Select all

00:00 - Detection start
00:51 - Detection complete; ready to write data
-------
00:51 - DVDFab's time to complete "detection/analysis"

00:00 - Start of data copy
08:36 - Data copy to HDD completed
-------
08:36 - DVDFab's time to complete "data copy"
09:27 - DVDFab's total time to transfer title data to DVD

On this particular DVD, with this "detection problem", MakeMKV took more than twice as long (10:39) as DVDFab for the overall copy. As mentioned earlier, MakeMKV's additional time is being "wasted" in the initial DVD detection stage, with the actual copying of the data being nearly identical between the two applications.

Of interest is the time it took to get to the message "Loop detected. Possibly due to unknown structure protection." ~4mins additional (each time CellWalk failed). If the "CellWalk algorithm failed" state is detected (or timed-out sooner) before the "CellTrim algorithm" is used perhaps this "detection" stage would be "quicker"...

Hope this helps.

Interesting results.

Just to be certain (I'm not that familiar with all of DVDFab's current capabilities) - Do these times include converting to and creating an .MKV file under both DVDFab and MakeMKV?

MKV is not a "conversion", it is a container type (like AVI MP4 etc). In terms of the supplied metric measures for this particular DVD, no conversions were performed.

DVDFab is a "more capable" application in that it provides a wide range of copy/re-encode/format-conversion/transfer options (none of which I need want/need).

The reason I've bought MakeMKV is for two reasons:
1) The native application/support for Linux (my OS of choice),
2) The license (one-time buy - with support).

DVDFab is only available on windows (tho it does run un-supported on WINE), and it's license scheme is just nuts (2 year subscription) - I first started with DVDFab, I couldn't figure out what to buy tho - the features and pricing all over the place (I couldn't figure out what all their products actually do !!).

MakeMKV is simple, fast, portable (Linux/OSX/Windows). You buy it, you "own" it. You go to this forum for support. It's what software should be. I bought it 'cause it's been in beta forever (FREE !!), this indicates to me that the developer is not just turning a quick buck by dumping crappy/buggy junk out for a few quick bucks.

For the record MakeMKV is *NOT* slower than DVDFab - they are largely on par - It's just that on THIS particular DVD, DVDFab's encryption detection/analysis algorithm is shown to be more mature/capable - hence my offer to help collect data that may contribute to improving MakeMKV...

Happy New Year !!

You are far from alone. After close to 10 years (perhaps more) of observing "fengtao" in action, I still smile when I think of how many different products he/she has simultaneously had on the market with "DVDFab" as part of their names - and to compound matters, the "DVDFab" name was "appropriated from a delightfully compact freeware program (You can still find it at "mrbass.org") ;>}

On the other side of the coin, "fengtao" has maintained "DVDFabHD" as freeware for several years now.

Please send IFO files for analysis, 11 minutes is too much especially if program read the same data over and over.

Most interesting, I had no idea that DVDFab had such a humble and open existence. I always thought the name was a little daft too... Regardless of the side of the coin, the product is obtuse and confusing to me !! Glad I went with the simple and aptly named MakeMKV !!

I'll get those IFO's tomorrow evening - how/where do you need them posted ?
