Regular dropouts of selectable CVD subtitles lt; quality, function, suddenly, however

andy

Well, due to my little cousin not givin up on bugging me to rip her some stuff I've started a new encoding sessions with the latest DVD2SVCD 1.1.0 build 1c under Win2k. I'm using two audio streams of 128 kbit each and 2 CVD subtitle streams.

The quality is really good however the subtitles frequently disappear while watching the movie. When I use the search function to 'rewind' and replay the scene the subtitles suddenly show up. The problem here is that this does happen in every movie and mostly at different scenes. So when I get the subs in chapter one and they suddenly stop next time I'm playing this chapter, there might be no dropout at all but suddenly in the next or previous one. So far there's no SVCD (I've done 3) that does no show this behaviour.

Though people in this thread conclude that this problem is related to the standalone player I'm inclined to believe it isn't. This is because I did not experience such problems on my standalone using previous versions of DVD2SVCD. Combining this with the info from the current readmeCode:
01 dec 2002 version 1.1.0 build 1c
- Bug Fix: Sometimes subtitles would dissapear at once, fixed (thanks          to Arianos and others)
it appears to me that this bug might not be fixed completely yet.

For a further test I used a friend's standalone which came up with the very same bug. When using my old encodes from older versions of DVD2SVCD I did not experience any such problems.

It is fixed! The problem you experience now is Player specific. How can I be so certain? Well, because the bug you refer to was visible in the subtitle txt files, which incidently Arianos points out in the thread too. I suggest that you check the same files first before shouting Bug Not Fixed!

Come on, he is making his point very politely and carefully. He does NOT shout. He says it MIGHT not be fixed COMPLETELY. He backs his statement with plenty of observations that might help to sort his observation in. I think his post is trying to help, not to blame.

He refers to a bug which IS fixed. Maybe he isn't shouting, but he is accusing me of _not_ fixing my bugs properly. If any of you had bothered searching for the thread where Arianos explains this bug you would see that the bug has nothing at all with whatever Chetwood is experiencing! (btw ux-3, you're shouting, do it again and I _will_ strike you!)

So here you contradict yourself!

On the one hand you say it's player specific because the bug is already fixed, therefore it _has to be_ my player.

On the other hand you say that I'm experiencing something totally different.

If any of you had bothered searching for the thread where Arianos explains this bug you would see that the bug has nothing at all with whatever Chetwood is experiencing!

So if what I'm experiencing is not related to the bug found by Arianos how can you know it's my player? It's quite improbable that it's the case. How can I be so certain?

Well, if you had bothered reading my initial post carefully you would have realized that I'd already tried my new SVCDs with other players that also showed this behavior. My old SVCDs I created with previous versions of DVD2SVCD do not have this problem on any of said players.

Well, does not exactly point to a player problem, does it?

Hi everybody.

@DVD2SVCD

First I really like your program and I think you are a great programmer. I would also like to thank you by bringing a great software to make svcds.

But I think you are being to harsh, most people don't understand coding as you do, sometimes we just are trying to help to possible bugs that exist. Off course is up to you to decide if it's a bug or not and we trust you to that. Don't think we are blaming you when we do that. We just wanna contribute for making DVD2SVCD even a more greater tool.

Merry Christmas and a Happy new year

If you were bombarded each and everyday with bugs in programs which you haven't made (cce, tmpgenc et al), you too would get fed up. Just because d2s is a frontend for those programs, users bomabrd me with issues of said programs. And now I'm to blame for dvd players shortcommings too (or maybe winsubmux bugs, who knows). I do not need that. In fact, I think I'll consider quitting this all together, it's bringing me down a place I don't wanna be!

I do not contradict myself. The bug you refer to is fixed. Period!

I am really sorry to hear that

I can say I am one of those people who sent you a, which I thought at that time, bug report. I am sorry for that.

Maybe there could be a sticky with bug reports so that the false bug reports could be solved at the forum by anyone here.

I wish I could help...

onesoul: Thanks for your sympathy, although that's not what I'm asking for. All I ask is, just sometimes, that there is put an effort and a measurable amount of intelligence behind posts and mails. I know, I'm the developer and therefore I have a unique perspective on the matter. And maybe today is just one of those days where I should have stayed in bed.

chetwood: Sorry I was harsh, it's just extremely hard sometimes. d2s is like walking against the wind sometimes. Anyway, try installing the version in which you know worked, then perhaps compare the used values between that and 1.1.0. Make sure to use the advanced level in the misc. tab, that way you can compare all used values.

dvd2svcd: you're welcome

We all have bad days, and we all can understand the headaches provoked by programing dvd2svcd and all that relates to it.
edtit: And yes, we all should do more research before mailing you bug reports. Hey people, let the artist work.

Please continue your great work

btw ux-3, you're shouting, do it again and I _will_ strike you!

I am not shouting, I have absolutely no reason to do so. I am just emphasizing key words used in another persons letter, try to point out that he words himself very carefully and in fact is not trying to say things as you interpret them. Actually, I can hardly think of other stuff he could have said or done, unless you would rather not hear from him at all.

Most people who come here and report bugs use your programm and are very fond of it. As others have pointed out in this thread, this is thought of as help, not criticism. So don't get upset. I suppose many here have done programming at some time. Those know quite well, how obnoxious bugs can be, and that fixing one bug will sometimes only uncover the next. As to your comments regarding being a front end, most of those people also had times when they despaired at their code, only to find out that the compiler had a bug as well. Myself, being of Fortran77 vintage, remember the agony too. And if you have to punch cards again, its even worse...

just for the record.
i have 3 dvd players that ALL play cvs subs. the players are jocel mp3000, mustek 562 and jocel q45. what hapends is that my svcds react diferent ways with the same svcd:
1.in the jocel mp3000, i have subtitles dropouts but comming back if i hit the subs key
2.in mustek all subs are visivel and no dropouts
3.in q45 the subs are all visible and i get no dropouts

this hapens only with some svcds, i thing it is the decoding card the one responsable for the gug becouse i already changed the drive in the mp3000

i have 2 freinds with jocel mp3000 that have sometimes the same problem with the subs.

so to those ones that are posting subs bugs, THERE IS NO BUG it is a player problem !!!!

I guess you don't have to get up to change your svcd's

Like I said in my posting to DVD2SVCD: I find it very hard to believe that 2 different players (gonna check a 3rd today at another friend's house) that flawlessly played all the subtitles off those SVCDs I've ripped with DVD2SVCD 1.09 b3 should suddenly be the reason for the subtitle dropouts.

Come on, the only thing that changed in my config here is the DVD2SVCD version. As suggested I'll reinstall this version and do another encode to verify this. Gonna get back to you then.

Ok, no problem, let's forget it. I hope we can narrow it down and fix this, whatever is causing it. Thanks for your efforts for this great tool.

.

BTW, the bug starts in version 1.1.0 b1, it's not in 1.09 b3 and of course it is not that certain bug mentioned by Arianos. Actually I don't have any idea what's causing it.

Hmm, weird. Well, I'll look into it. Since so many players fail for you I should be able to get one of my friends to help me. The strange part is I _always_ use more than one CVD stream (mostly da, nl, no and se) and I don't ever get dropouts on da (danish) on my player (even when using 1.1.0). But as I said some of my friends have other brands of dvd players and I will test on those.

Ok, I have investigated the problem and the only thing I found that was different between 1.0.9 and 1.1.0 was that the bmp palette for the last 12 entries in 1.1.0 was different. Also the start and end times were sligtly different, 1.1.0 is more accurate in this regard. So, Chetwood, if you have some time, try this:

1. use 1.0.9 to rip the subtitles
2. after that use 1.1.0 to do the conversion as normal, including subtitle ripping. When for instance the video encoding starts copy the subs extracted from 1.0.9 into 1.1.0's sub folder.
3. Burn it when it's done and see if you're still experiencing dropouts.

I've done exactly this and I still get the dropouts. Sorry, in case you need some logfiles let me know...

Ok. And if you convert a dvd using 1.0.9 B3 you don't experience dropouts at all (using the same dvd to compare of course)?

Please post your SubLog1.txt located in the subs folder.

I have also experimented troubles with CVD subtitles with the latest DVD2SVCD 1.1.0 build 1c. After some checks I found that the computation of the Y-position (Ypos) in version 1.1.0 build 1c differs from that of the 1.0.9 B3 version. In my standalone player, the troubles appear when (Ypos + height) is greater than 500. Therefore, at present I modify the Ypos in the sub file as follows:

if (Ypos + height gt; 500) then Ypos = 500 - height. Otherwise,
don't change Ypos.

@dvd2svcd: Please check if the computation of the Ypos in the current version differs from that of the 1.0.9 B3 version.

Best,
