Video Freezing...

[otpelk]

i have done Reign of Fire, X-files (the movie), and minority report, on various versions. Only minority report yielded no playback problems...the other two will freeze halfway through the movie. My question is, i noticed i didnt put the MPEG2Dec3dg.dll in my avisynth/plugins directory, but in my dvdrb folder...could this be a problem. I do have DVDrb set up to point at MPEG2Dec3dg.dll in my dvdrb folder but could this possibly be the source of my problems. Thought i would ask befor doing another 5 hour encode.

TIA,
otpelk

[wmansir]

That wouldn't cause a problem (as long as you point DVD-RB to it and check the "add to avs" box). If DVD-RB was having a problem with finding Mpeg2Dec.dll the error would be much more apparent (like error messages, massive undersizing, and no video in the output).

As for your original problem, my first thougt is a media/burn issue (if this is only happening in your standalone). Have you used other DVD backup programs with the same burner/media/standalone combination without any problems?

[otpelk]

Yes i have used a vast variety of backup options, dvdshrink, IC8.0, clonedvd with same media i'm using now and on the same standalone and have had no problems at all. Just for the heck of it i went ahead and put the .dll in my plugins directory and remove the path from my .ini file and unticked the add to AVS box. I was also doing this in one-click mode...gonna try the 3 click process and see what happens. Thanks for the quick response.

otpelk

*EDIT* I should also add.. on the X-files (Region 1 NTSC) backup attempt, I tried two different times with two different versions of DVDrb and the freeze occured in the same exact spot. :confused: :confused:

[otpelk]

Well i tried what i said and still the video freezes in the same spot. Tried on two different types of media (hp dvd+rw and ridata w/ ricohjpn something or another media code) and I used Nero and Imgtool/dvd-decryptor to burn ending up with the same results. I'm about at my wits end and don't know what else to try. I guess i could uninstall re-install avisynth and stuff and see what happens from there. This is all happening on a sony dvp-ns325 standalone. Anybody have any ideas?

*EDIT* I just played the .m2v files created by dvdrb and by the looks of things the feeze is happening going from vobid 1 to vobid 2. (actuall dvd plays through V01000500001006.m2v freeze occurs going to V01000600002001.m2v)

[wmansir]

Can you skip past the spot it freezes at and play the rest of the movie?

If it is just one spot around the halfway point I would suspect something is up with the layerbreak, although I haven't seen any reports of problems with it before this..

[otpelk]

yes i can skip past and play the rest just fine. Looking at the .ifo file...Layer break is in chapter 7...my problems occur in chapter 6.

[mrslacker]

Same problem here. I can also fast forward through it, but it is always the same spot with any media. My freezes are also at the seams of the m2v files. I've been investigating this recently but I'm stumped. As a note, the freezes happen with material encoded with CCE SP or QuEnc.

I'm using a Sony DVP-NC665P. Why would there be problems going from segment to segment?

Someone else brought this up (http://forum.doom9.org/showthread.php?s=&threadid=78336) recently too.

[otpelk]

not to be pushy or anything, but is this being looked into at all?

thx

[Joergen]

What, layer break removal? For now I'd suggest decrypting your discs using DVDShrink (select no compression for everything). That takes the layerbreak out nicely.

Btw you dont have to redo your previously freezing movie, just run that disc through shrink and burn again.

[mrslacker]

I think we're talking about freezes not related to a layer break. It can happen multiple times, usually within a couple minutes after starting, and seemingly between encoding segments. I haven't taken the time to look at all the exact positions, but I know at least one is right on the transition. There was a rather large change in bitrate from the end of one segment to the start of the next. This was a drop from roughly 8000 to 3000 kbps in this one case. I wonder if this could result in effectively out of spec VBR for a standalone. This info is based on bitrate viewer.

Just to settle speculation about the layer break hypothesis, I generally run any problem discs through DVD Shrink just to see if it sorts anything out. It doesn't seem to help anything in this case.

As a side note, the difference between a vbr_bias of 20 and 35 is barely noticible when looking at the bitrate viewer plot. Interesting. However, they are both completely different from the source vob bitrate. When I get a chance, I thought I'd try a much higher bias setting to prevent high bitrate swings even between encoding segments by flattening the entire bitrate profile.

[Joergen]

Interesting point about the possible huge bitrate drop. Its common in DVB transmissions that when the bitrate is radically changed (say between one show and the next) there is a significant audio drop-out of 500-1000ms but no freezes. But like hopefully most users, I'm free of freezing or drop-outs since 0.3x

[mrslacker]

Now if only everything could be encoded together. Every segment is totally independent and in a vacuum, as encoding parameters can differ from one to the next. I do remember reading that CCE SP 2.67.0.27 could work directly with something like rebuilder.ecl (multiple item.ecl in one). Even if that worked, I doubt if the encoder would treat it as more than a just batch.

[Joergen]

It might be that segmented encoding is a must for rebuilding, and it has its benefits like sampling the output before the encoding has gone on for long, and distributed encoding with RBFarm.

[wmansir]

jdobbs stated one of the major benifits of segmented encoding was that an I-frame is placed at the beginning of each cell (like it should be), even with encoders that don't support forced I-frame insertion (like CCE Basic). It may also be required for other reasons I am not aware of.

[RaistlinMajere]

Both of my sony standalones (different models few years apart) give the same problem. I encoded "I'm Alan Partrdige series 1" and at the end of every episode is a short clip that has a different vob id to actual episode. This causes the freeze. It does exactly the same for all 6 episodes.

For example

Episode one is 6 chapters of vod id's 1,1 to 1,6 and the end clip is 2,1 (chapter 7)

Episode two is 6 chapters of vob id 3,1 to 3,6 , end clip 4,1 and so on

at the end of chapter six of each episode at the vobid change the chapter counter on my standalones doesn't advance to 7 as it should (it stays at 6 even though its playing ch 7) but the video keeps playing into chapter 7. Until it gets to the end of chapter 7 where it freezes.

If i forward past this point and press chapter back it goes to chapter 7 on the display and plays the end clip fine and advances to the next episode. It does this same thing for every episode at the same point where the vob id changes. It plays fine in windvd though.


Other than this is all works perfectly. I have tried this same thing with rebuilder versions 53 and 55b. I am using cce 2.5sp. I do hope this can be fixed as it the only thing stopping me using rb over the old tmpgenc/ifoedit way

[Joergen]

It would be interesting to see if these freezes are infact the layer break. Could any of you run the disc with the freeze (the one you burnt) through dvdshrink with no compression to remove the layer break, then burn onto -RW or if you want to waste an -R.. and see if it helps?

We have come to forget that the layer break caused freezing for some people when DVDShrink was new and was the most complained about thing/feature.. and DVD-RB doesnt remove the break yet afaik.

[woah!]

this is a layer break problem as i have now got over it with my sony dvd player.

i do this before i run the rebuilder:

1. Open the movie's IFO, usually VTS_01_0.IFO, with IFOEdit
2. Note the cell number where the layer break occurs.
3. Note the PGC number, usually PGC_1
4. Expand VTS_PGCITI and select the PGC noted at (3)
5. Scroll down until you find the cell number noted at (2)
6. The very first entry for that cell - cell type - will have some value other than 8.
7. Double click this line and change the value by adding 8 to whatever's there now. Thus, if it's 2 make it 10, if it's 0 make it 8.
8. Save the file.
9. You may want to do a Get VTS sectors, too. It isn't strictly necessary, but it does confirm the general integrity of the files. For instance, this last action showed up problems in version 2.2 of Shrink (no longer present in 2.3)

this makes sure the layerbreak is removed for me.
maybe with these series dvd's there are more layerbreaks after every episode,but this way you should be able to remove them the same way as above.

like i said this solved my freezing with a Sony dvd player.

[RaistlinMajere]

nice idea but i have never had problems with layer breaks. There are only layer breaks in episode 3 and i don't get freezing at the point. It is something to do with when it changes vob id to a new first number ie 2,4 to 3,1. I have encoded the same disc with tmpgenc and ifoedit and don't get the freezes. I think it has something to do with the timecodes as its the timer that goes wrong when the player fails to reconginse a chapter advance. This is purely a dvdrebuilder problem as I tired the same disc with other methods and had no freezes.

[M!ro]

i have the freezing video on layer break problem too. :(

i did a movie with dvd rebuilder (0.53a i think) and i had a cell type 2 on layer break. so i changed it from 2 to 8 and on sony stand-alone player it just freezes when it enters that cell. then i put it back on 2 and ran it thru dvdshrink (no compression). it changed cell type to 10 but on stand-alone video got frozen again on the same spot, when entering cell with layer break.

basicly it works only with cell type 2. rest of the movie plays fine, without any problems, but i was unable to remove layer break :(

[nonkeljef]

Same problem as otpelk
*EDIT* I just played the .m2v files created by dvdrb and by the looks of things the freeze is happening going from vobid 1 to vobid 2.
DVDRB 055b
CCE 2.67 SP
DVD Unbreakable palr2


EDIT preprocessing with dvdfab 1.95 layer break removed.

[Joergen]

ID1 and ID2 seem to be the for the split between the layers, where ID2 is on the second layer. I cant believe this "simple" problem is surprising people in this day and age, although I do think the layerbreak removal should be done by dvd-rb, but not until its tested and done proplerly. There is a big chance to mess the layerbreak and end up with problems for all those standalones that handle the layerbreak fine.

[nonkeljef]

Video freeze
For me,it has nothing to do with layer break.Because my dvdrb output freezes on the transition from vobid1/13 to vobid2/1 and the layer break is in the original at vobid2/7

Both preprocessing - dvdfab and shrink - same result.
No problem with movies with only 1 vobid.

BTW great results.

EDIT- Plays fine in windvd and powerdvd. Problem with my Sony standalone.

It might be just an coinsidence but, mine got frozen when switching from VobID 2/18 to VobID 3/1 where VobID 3/1 is actual layer break, and this cell needs cell type 2. Otherwise video gets frozen.

PowerDVD working fine, but standalone not. And, yeah, it's Sony.

[Alurker]

I have the same problem with my sony standalone player, everything I do with versions .050 and above of RB does this, but works fine on other players. If I use .049 it plays just fine in my sony player.

[RaistlinMajere]

I will have a go with version 0.49, to see if it fixes the problem. I will let you know how i get on

[jdobbs]

Let me know if it works. At least I'll have a place to start.

[Alurker]

The 1 thing thats wierd about these pauses, is that if I nudge it with a touch of fast-foward it starts playing again. Then in a minute or 2 it will freeze again, then I nudge it and it starts working again. I get about 20 some freezes to the movie. I have not tried the newest version yet .055b to see how it works.
Sony 725p player and I burned it with Nero recoder2.

Sony 725p player and I burned it with Nero recoder2. Do you have any other burning software you could try? I'd like to see if it makes a difference.

[Alurker]

Yes I can try and burn it with Decryptor as a ISO instead of using NERO burning rom or recode. I will try it and get back with you after I encode 1 in a few hours.

[nonkeljef]

Do you have any other burning software you could try? I'd like to see if it makes a difference
My problem output is burned with the latest CopytoDVD

[dragongodz]

you could also use ifoedit to see if the problem cells have a STC discontinuity in the original ifo.

load the relevant ifo and click on VTS_PGCITI , select the relevant PGC. in the bottom window scroll down until you get to the cell descriptions.

[RaistlinMajere]

the cells that cause the problems for me have the STC discontinuity flag in the original ifo. What does this flag mean? Would it affect the playback if i altered the flag to no?

[jdobbs]

That may cause more problems, but it doesn't hurt to try. Usually you'll see a dramatic change in time where the STC is flagged (normally the SCR goes back to 0). DVD-R will reset the timecode also in order to keep it true to the original.

[RaistlinMajere]

i take it the command happens at the end of the cell to reset the timecode. It won't make a diiference in this case then as the problem is the beginning of this cell.

[dragongodz]

no it happens at the start of a new vob-id. so the time resets back to 0 at the start of that cell.

[Alurker]

Ok, I encoded "The WAR" using 55b of RB which I have not tried yet and was going to make 2 copies. 1 burned with NERO running it thru Recode2 and the other with DVD-Decryptor but now the one with NERO played just fine in my Stand-alone Sony player.

All other version in the 50's I've tried has had the freezing problem but now 55b seems to work ok. I check it with INFOEDIT and it did have some STC disc flags on the 1st and last cell's only. but played just fine when burned using NERO.

[RaistlinMajere]

I tried encoding the problem disc with version 0.49 and it works perfectly on my standalones.

I burned with nero , although i had the problems with the later versions v0.53 and v0.55b and I also used nero then so i don't think its to do with burning programs.

I hope this info helps, if you need anymore details or perhaps the ifo's let me know. I'd be glad to help.

[nonkeljef]

I did Face/Off r2 pal wich has 3 vobid.
DVDRB 055
CCE 2.67
3 step metod
Output the same known issue as mentioned in other replys. It freezes twice when vobid 2 begin to play and also at the start of vobid 3.

Now i ran the output through Dvdremake, burned with Nero and you can guess : all plays without any trouble on my Sony standalone.
So i presume that the rebuilding phase may cause it.

[dragongodz]

can you compare the ifos before dvdremake and the ones after ?

[Joergen]

Has anybody else tried running a freezing disc through dvdremake? It'd be very positive if that can fix a freezing disc and also means jdobbs has something to compare.

[nonkeljef]

can you compare the ifos before dvdremake and the ones after ?
I'm a newbie concerning this dvd stuff. The only thing that is totaly different to each other are the time map tables in the ifo files.

[otpelk]

glad this finally got some attention, as i have been away for a while :P

Just to clarify things on my end a bit more clearly, this is definately not a layer break problem. I still have my Reign of Fire rip on my pc and running it through dvdremake right now to see what that does...will update as soon as i find out what happens. Thank you all for your input.

otpelk

[jdobbs]

I would be genuinely surprised if this related back to the time map table...

Also, I'll check tonight -- but I'm almost positive I used 5 seconds as the unit in my code... are you sure these aren't backwards?

[otpelk]

just burned after running through remake and no freeze. However i was observing the counter, and right before the spot where it was freezing, the counter was going crazy i.e. it would go like... 55:56 to 55:57 then back to 55:56 then to 55:58..it would count like this for 5 seconds or so, then once through the problem area it would count normall...hope this info helps

otpelk

[otpelk]

Jdobbs..the time unit in for me is 3 in my dvdrb generated ifo

[00000014] Time unit (in seconds) 3 [03]

And remake output ifo is 5

[00000014] Time unit (in seconds) 5 [05]

thought i would let you know this in relation to your last post.

EDIT***original ifo from dvd is also set to 3 maybe you would like to see a copy of all three ifo's?

its wierd how dvd-remake changed the unit to 5 and now its not freezing however with dvd-rebuilder used original time unit and freezes. not saying thats the problem but maybe if you seen the ifo's you may be able to see something that i dont because i dont understand 95% of the stuff in an .ifo file :P I are be confused
:confused: :confused: :confused:

[eddevrs]

On my Sony player NS330 my rebuilded movie freezes at the end of every chapter. Only Sony! On the PC no problem.

The movie (The Abyss - Special Edition - R2) is pre-authored with DVDShrink (to remove everything but the main movie) and compressed with DVDRebuilder + CCE 2.5 (5 passes).

This is only the case with the newest version 0.55b! Previous ones (e.g. 0.53 series) were ok. I had problems with the subtitling, I was hoping that they were solved in 0.55b. Movie is converted from 4:3 to 16:9.

I've deleted the IFO/BUP set and made a new one with IfoEdit, but that didn't work. I don't know much of the DVD structure, but it seems that the problem is in the VOB files.

:confused: :confused: :confused: It really shouldn't matter. As I said above... I'd be very surprised if this was related to the problem at all. The IFO wouldn't be the first place I'd suspect for this kind of problem. But it's always possible and I'll look at it.

[cmsoliveira]

Hi, there

I have the same problem as otpelk, also with reign of fire, R2 pal.

I'm using DVD-RB 0.54 and i have the same freezing problem in the exact same spot. I'll run it thru dvd-Remake later (no way near computer right now :)) and see if it fixes the problem.

Also, using Sony DavS-300, and this is the first time I see this problem, in several dvd Backups.

OT: How can i see the Time unit using Ifoedit???

[RaistlinMajere]

Hi, I have had the problem again using 0.49 on The Last Samurai. The problem seems to happen at the point where the vob id changed from 1.X to 2.X. I used vobedit to demux the streams and used ifoedit to reauthor the streams. While trying to reauthor ifoedit reported buffer underruns on the sub streams and when playing the reauthered film back the subtitles work fine up until the freeze point where after they don't show even on my pc.

I guess the problem is with the subtitles. I am going to try the disc without any subtitles in see if it works ok in my standalone. Will let you know

update - I reauthored the bare streams without the subtitles and it plays fine on the pc and my standalone

update 2 - i tried just stripping the subtitles from the original encode which freezes on my standalone using ifoedit, even with the subtitles removed it still freezes.

I wish I knew more about dvd structure so I could be of more help. I would like to try dvd-remake to see if it fixes the problem as suggested, but i can't afford it at the moment (and the demo version doesn't let you save so how can you test it)

[nonkeljef]

I've tried versions 0.52 , 0.53 , 0.54 and 0.55. All give the same problem with more than 1 vobid.
