SVCDs with 48khz Audio

[elister]

Well after finnally getting DVD2SVCD to work properly (by downloading CCE) I decided to do a major rip. Yet when I encoded it, I told BeSweet to "Do not convert audio (use source audio)", thinking why convert it to 44khz when im just going to turn around and convert it back to 48khz.

Welp, I guess SVCD2DVDMPEG+ didnt like that. So I selected the option to skip the conversion. Still no go.

What its doing is creating a bunch of mpeg a/v files. Mpgtx gives me some error message as well. Then suddenly, the program stops at Multipexing elementary streams.

############### New MPEG File ###############
File: D:\DVDRip\Dune\Dune1a.mpg
Horizontal Res: 480
Audio SampleRate: 48000

******** Demultipexing original mpg file

******** Resampling audio from 44.1 KHz to 48 KHz

Skipping....

******** Multipexing elementry streams







When I try to bring up the "Mpeg Info", my system slows down and nothing comes up. Skip the audio encoding, AC3, mpeg pass 2, nothing seems to work.

Well in principle if your audio is 48k it will not do anything at the resample stage. Also if you select skip - this would be the case. Therefore your logic is spot on. Unfortunalty you have one of the two issues i refer to in https://www.videohelp.com/forum/viewtopic.php?t=163340&start=0&postdays=0&postorder=asc&highlight=

For what its worth I've probably done about the same number if DVDRs and have seen just two showstopping issues:

- evergrowing file at demux phase (a mpv file is create which consumes you whole HD!)
- OR again on demuxing, many small files are produced when you would expect 2

The above scenarios have happened just twice for me from about 100+ source mpgs...... That said i couldn't see what i could do as a workaround.

Nothing can be done as the original mpegs are not conforming to what is expected by the demuxer.

Sorry.

Did you encode the mpgs yourself?

Did you encode the mpgs yourself?

Yeah I did. This was one of two DVDs I did. And im just now remembering that I used the same method. The first one was also 48khz audio (checked the encoded svcds).

Encoded on the same machine, using the same method. One movie works, the other does not.

Working Movie.

Mpeg 2 Program Stream File [Video/Audio]
Muxrate : 3.29 Mbps
Estimated Duration: 46:08.21s
Aspect ratio 4/3 (TV)
Not interlaced, chroma format: 4:2:0
Size [480 x 480] 29.97 fps 2.53 Mbps
Audio : Mpeg 1 layer 2
128 kbps 48000 Hz
Stereo, No emphasis

Non Working Movie.

No information at all.

Loooks like im screwed, looking up the video properties in mplayer2, the only difference between the two movies is that the Dune one (the one thats not working) doesnt display any Video Filter Properties in the Video Renderer where as the other one does.

Me thinks ill have to re-encode this, and dumb it down in the process.

[ChrissyBoy]

Sounds to me like the mpegs for dune are just badly structured. I'd reencode or bin it. You could try avicodec http://avicodec.duby.info/ which also gives mpeg details from the context menu.....

Im not sure, but I think the best method is to just use DVD2AVI and convert it to a DiVX format, then re-encode it back to SVCD.

Here is the AVI Codec info.

File : 795 Mb (0 Mb), duration 0:00:00, type MPG, 1 audio stream(s), quality 88 %
Video : 0 Mb, 2530 Kbps, 29.970 fps, res. 480*480 (16:9), MPG2 = MPEG 2 (SVCD/DVD), supported
Audio : 0 Mb, 192 Kbps, 48000 Hz, 2 chan., 0x2000 = AC3 DVM [0x80], supported

Off to work, thanks for the help.

CB, might I make a suggestion?

I know - we're always adding more work for you.

In eventuality, you know you're just going to have to bite the bullet and either find new muxer/demuxer routines (as well as others) OR write your own, yeah?

As a first (easy) step, why not make it optional?

You know, make it an option to accept separate audio and video streams.

I wonder if TMPGEnc's mux/demux can be called from the command line? The ones you're using seem overly picky.

Ok, I think I know what I did wrong, how the mpeg got hosed.

Aparently, I had used DVD Shrink 2.1 to rip the DVD to the HD, and then encoded the VOBs with DVD2SVCD. It had re-compressed the VOBs me thinks.

Having re-rented the same movie, ripping with DVDDecryptor, and encoding with DVD2SVCD, I now have SVCD compliant mpegs, which merge just fine. Two different mpegs, looks the same, just that one is hosed, the other isnt.

Nonetheless, the main reason why SVCD2DVDMPG wasnt working, was that the mpegs were not compliant.
