Missing audio in 1.06.2 pre-2

[markrb]

I just finished an encode of Rock Star with DVD2SVCD 1.06.2 pre 2 and about 1/3 of the audio is missing. The movie is 1:46 or so and there is only 1:20 of audio. The mp2 file shows the same length when in Media Player. All the video is there.
I don't know how to check the .ac3 file or I would check that as well.
I used one audio track and no subtitles, region 1 English.
No errors in the DVD2SVCD.log file.

Just found out that media player will actually play the .ac3 file.
It has the entire audio, all 1:46. So the problem is somewhere between the making of the .ac3 and the making of the .mp2 file.
I am going to run the audio section of the encode again and see what happens.

This happened to me once too, on an earlier build, pre-BeSweet (1.0.5).

For me, it only happened with 48 kHz audio -- when I did a conversion to 44.1 kHz, I got all the audio again.

It's only happened to me once, so I didn't pursue the problem further, and I encode all my audio at 48 kHz.

[markrb]

Just finished the audio encoding part and I watched it closely BeSweet ended early. This time at 1:15.
The first time I had downsample checked and this time I unchecked it.
In both cases the .ac3 file has all the audio.
This is definately the 1.0 version.

I have found audio missing also.
but it was after bbmpeg stopped working at 57%
it wasnt frozen it was just running at 99% CPU doing nothing.
I stopped it & did a crash recovery. same result 57%

I then put it down to the movie "3 Kings"

I then did rip from Vob 6 only (13 mins approx)
the audio was ok for 1/2 of it then the sound stopped but the movie continued (about 30% faster than normal).
the audio was also out of sync by about 1 sec whilst it worked!

I did notice that the bbmpeg section had values of 160 (I think)entered for Video/audio1/audio2 startup delays.


I have now set them to zero & i am re-encoding the last Vob again as a test.

[markrb]

I just tried 1.06 build 1 and the same thing. I think the problem might be with the VOB files since I am using the same ones. I no longer have access to the DVD.
Funny that the ac3 files should have the whole audio stream though, but it could be that the ac3 stream is corrupted somehow.
I am going to try a pre BeSweet version and see if it will work.

a Bit off topic but:

congratulations on your new "title" Markrb :)
I wondered how long it would take ;)

keep up the good work.

[Slick]

Finished re-encoding from scratch the last VOB (3 Kings)
all audio there now but out of sync by around 1 sec. (audio late) :confused:

[markrb]

Thanks for the good words.

I tried 1.06.1 released version and I had the same problem audio ended at 1:15 of a 1:46 minute movie.

I have just finished the audio protion of DVD2SVCD with version 1.04.2(I had problems with all 1.05 versions so I never even tried it) and the final audio has the correct length and all the audio is there.

All of this was using the same VOB files ripped with 1.06.2 Pre 1 internal routines.

Video encoding has not finished so I cannot say what the final outcome of the muxing will be, but at least all my audio is there now.

Hi Markrb.

I started a full encode of the same Movie (3 Kings) before I went out tonight, it has about 1.5hrs left (3 passes) using 1.06.2pre-1
I couldnt get a clean copy using pre-2.
it's strange because I did 2 movies using Pre-1 & they were fine. I dont believe there is much difference in pre-2 to cause the problem.
unless DVD2SVCD intended this ver as a test for BBmpeg!
if it was it failed on my machine both in BBmpeg at 57% (full movie) & with the audio on a short encode.

unless of course it's the movie or DVD?

Question:
VOB's are normally around 1,048.574 in size
have you ever seen a VOB at a considerably smaller size than the rest when it is not the last VOB?

in 3 Kings VOB Number 4 out of 6 is around 3mins in length (177.314kb)
it also seems to be the point BBmpeg stops encoding.

IE:
VTS_01_01 =1,048.574
VTS_01_02 =1,048.574
VTS_01_03 =1,048.574
VTS_01_04 =177.314 *** (NEVER SEEN THIS BEFORE)(FAILS AT 57% IN bbMPEG?)
VTS_01_05 =1,048.574
VTS_01_06 =706,892

[markrb]

Found out that there seems to be a new bug introduced in the pre version. I think it has to do with ripping and adding a flag or not adding a flag into the ac3 stream.

I was able to finish the encode fine with 1.04.2.

Slick you may want to try ripping that again with Vstrip and see what happens.
I would also back up to the 1.06.1 full release and update BeSweet to 1.0 like DVD2SVCD has said to do. The Pre releases are not meant for general release and was only meant for people that where having CCE problems. They are pre after all.

Mark

[Slick]

cheers markrb I'll try that.



The Pre releases are not meant for general release and was only meant for people that where having CCE problems. They are pre after all.

Yep I appreciate that, but if the "pre" cures the faults in CCE for the unfortunates, then introduces other problems for everyone. then it's gotta be worth trying it.


P.S.

it failed again last night @ 63% in BBmpeg. (internal ripping)

i'll try Vstrip as you suggested. using 1.06 Rel 1 with v1.0 besweet

[Mortal]

This morning, bbmpeg hung at 39 % of the muxing process. This happened twice now with two different movies since I've installed the Pre 2. Strange: using two audio tracks, there were two extracted audio files which seem to have the right size, but only one of them would be encoded correctly. After encoding, I had an audio 1 file 3,9 Mb of size and one w/ 158 MB. This ist what causes bbmpeg to hang, I assume. What should I do? Go back to Build 1 Pre 7? This one seemed to work fine for me, but had no Bilinear Resize included. The CCE hangups are solved only since 1.06 Pre 7, so there's no going back to an earlier version of DVD2SVCD.

Can somebody help me on this?

[Slick]

@Markrb
O.K. I think I have either a bad Disk. or 3 Kings will not copy for some reason.
I uninstalled the Pre release & installed the 1.06 rel 1 & updated the besweet to v1.0.
I used Vstrip as you recomended. it failed again at 64% in bbmpeg :(

the crazy part, is that BBmpeg is not frozen! it's just taking up 100% CPU with only 111mb pagefile! & going nowhere.

anyone out there already copied this movie?

I don't usually have any trouble at all with DVD2SVCD. :confused:

[Mortal]

Just have a look at the size of your audio file, maybe you're having the same problem as I do. BBMpeg freezes when it encounters an audio file that is somehow corrupt. Since 1.06 full, something happened with the audio encoding routine. At least that's my suspicion.

[markrb]

Slick just for testing reasons try going back to the last version you knew worked 100%, in my case that was 1.04.2 and re-rip and see what happens. When I went back it worked fine.

Before you do that check the length of your mp2 file in media player. See if it matches the length of your movie. I was missing almost 25 minutes at one time. You can also open your .ac3 file in media player and see if that matches the time of your mp2 file.

@markrb & Mortal

yes that seems to be the problem.
the encoded_audio_1.mp2 = 23mins only.
around 83mins of audio missing.

** the encoded_audio_1.ac3 file had all the audio there. **

I have gone back to ver 1.05 build 4 to try it again.
currently @ 99% complete in CCE

audio sizes look more like it now.

I'll let you know when it is finished.

** update **

O.k. that worked. everything right now :)
it would seem that there is a problem with besweet, at least with "3 KINGS".
strange because I've done a few movies with ver 1.06 build 1 without this problem :confused:
oh well stick with ver 1.05 b1 until problem resolved.

@dvd2svcd
if this is a problem & not just down to individual movies / machines.
I will do some testing for you should you require it.

[Arianos]

1.06.b2 pre 2 Test results:
Overconfident, I did 3 movies during the weekend with 1.06.b2 pre 2: "Beautiful", "The Lost Son" and "What's Cooking". Ripping methods: 1,3: Internal Routines, 2: DVD Decrypter. All VOBs OK. Experienced my first ever CCE "crashings" (2 VBR). Overcame that with only one Crash Recovery (each), finished OK, only to find out that the last 20 minutes of Beautiful had no sound (Nor SVCD Subtitles, nor chapter marks...), and of all three, the last 5-10 minutes were missing altogether.. All 3 movies done on a P4@1500 with 512 RAM. All files erased to make space. Only 20Gigs free on that one... overconfidence,
the :devil: made me do it....
(sigh..) Oh, well.. Back to 1.06.b1 for me for now :)
P.S.1
I'm NOT complaining. Just stating some "incidents".
P.S.2
Grateful for the subtitles option. I hope I will be able to use it soon though. Keep up the good work!!!

[dvd2svcd]

I just don't get it. I have done 5 movies now (using the default settings in dvd2svcd) and none of them chopped the end of the movies. I wonder where this problem lies.

Regarding to the sound that is missing is due to a bug in besweet. As soon as DSPguru releases the next version I will release a new version of dvd2svcd.

Hi Guys,

Same thing has just happened to me with the pre-release. The .mp2 file created was suppose to be 1h 40m long but only 35 minutes were encoded. Reinstalled 1.0.6b1, which didn't give me any problems previously, and re-encoded the already ripped vobs on the harddrive and the same audio cutoff occurred. Tried re-ripping the vobs from the DVD and the audio problem was solved. Hence, do you think the audio cutoff problems lies during the ripping of the vobs using the pre-release instead of Besweet itself since my problem was solved only after I reinstalled b1 and re-ripped the DVD as the already ripped vobs from the pre-release gave me the exact same audio cutoff? Thanks.

Addition to posting above, but I doubt it will provide anything useful:

Well, I DID go off a little from the default settings:
1. As all 3 movies were under 2 hrs, I set the CDs for 805 MBs. But I always do that, plus the second CD in no case was full.
2. 1,3 had subtitles, 2 didn't.
2. Based on other members suggestions, I played with TS, Avisynth Bicubic C value to 0.65, and a little with the settings in Bitrate, never exceeding 2400.
Maybe something got "stuck" there? I do not care about the encodings. I can always do them again. It's the CCE freezings that got me worried. Plus I also encountered the "CCE waiting to hit encode" glitch, mentioned elsewhere for WinXP, but I didn't give it further thought, as I am sure it is a temporary side effect from the general CCE Quest.
Uhm, on the BeSweet comment: Does that mean we should go back to 0.95? Yesterday I watched "Rated X" encoded with 1.06.b1,(BeSweet 1.0) Everything mostly ok. The only thing I noticed is some faint "kliks" on the dialogue parts and some random spilling of the sound to the surround channels. Or do I ask for too much? :)

I doubt that, for it worked for me to use the same ripped .vobs and .ifo with 1.06 B 1. I had a hangup in BBMPEG (!), though, but with Crash Recovery it worked out fine. I think the .d2v file didn't hand over the correct value because I switched to a previous version of DVD2SVCD, and the warning shown may have its reason ("This d2v was produced by an earlier version and might...") :-)))

Movie was Magnolia. For me the problem lies in the audio encoding procedure of the second audio track, for the "extracted_audio" tracks were both ok. The "encoded_audio" was corrupt, at least one of them, and this happened with 1.06 B2 Pre 2 only. I point to BeSweet, if asked. It encodes -independent of the film, I had two different efforts- one perfect audio track of about 150 MB and a small one sized 7 MB. This causes BBMPEG to freeze. At least that's my experience.

It works out fine w/ 1.06 B1, assuming you manually calculate the avg bitrate. I'm using a very simple calculator, and there's no cutoff.

If the great author manages to kill this small bug, the aim ist reached. 1.06 B1 is already close to perfection after all. Go on like this, DVD2SVCD!
