DVD with PCM audio

[wincent]

Yesterday, I spent the day looking for a software that allows to author DVD with a PCM audio track.
But, authoring tools only accept mp2 or ac3 audio tracks and muxers like mplex or muxman cannot mux .m1v video files with .wav audio files.
So, how can I author a DVD with 1 PCM audio track ?

[bigotti5]

muxman cannot mux .m1v video files with .wav audio files

Muxman can...
Something wrong in your assets?
What says logfile (C:\muxman.log)?

[Zeul]

The chances are your wav file is 44.1KHZ instead of 48KHZ which would then be rejected.

btw there is no need to double post - please refrain from doing so again.

At the end of the muxing, I get the following message :
"1 oddities detected, resulting DVD is non-standard. Check log for details."

Actually, I tried to author a DVD with Gui for Authordvd. As it only accepts .mp2 or .ac3 audio files, I did "Create Batch DVD" and looked in the batch files. I noticed the first step was to mux the elementary video stream and the audio file with mplex. But, mplex cannot mux M1V and PCM, so I have looked for a program that would allow me to do it. Since, muxman produces .vob files, I guess I have to demux these .vob to .mpg.

MuxMan doesn't complain the pcm audio.
It's the number of fields of the video stream, that exceeds the DVD standard.
If you burn this DVD, you have a chance that it will play flawlessly in newer standalones, but stutter in older ones.

To be standard compliant, you need to correct the GOP length of the video stream before feeding it into MuxMan.
You can do it for example with "GOP fixer" as integrated tool of Womble Video Wizard.

Thank you for your reply goonix.
I run GOP fixer to correct the .VOB file created by muxman because it fails on fixing the elementary video file .m1v.
Now, how can I demux the .vob file to a .mpg file (required by authordvd) ?

[goonix]

Use PgcDemux.

Actually, PgcDemux demux to elementary mpeg (.m1v or .m2v).
Moreover, it turns out that .m1v can only be muxed with mp2 audio in an mpeg1 file. So, I think one cannot make a DVD with 352*288 mpeg1 video and PCM or AC3 audio.
I will have to encode my videos to MPEG2.

So, I think one cannot make a DVD with 352*288 mpeg1 video and PCM or AC3 audio. Those are legitimate combinations, and MuxMan will produce them. Pay attention to the error message. Your video contains some garbage after the last sequence_end (not the cause of the problem), and the GOP size is not DVD compliant (which causes MuxMan to not produce the ifo files)

I used it to join my original mpeg1 videos and demux to an m1v elementary file.

I think my .m1v is corrupted because when I fixed the GOP problem with gop fixer, the resulting file was truncated.
And Muxman do produce the ifo files, but it warns that the GOP size is not DVD compliant and the DVD may not be played.

I don't think this is correct. I have used Scenarist 3.0 to make a DVD with MPEG-1 video and it would only accept AC3 audio. It refused to accept PCM. I live in NTSC land, so trying MPEG audio is not an option for me.

I live in NTSC land, so trying MPEG audio is not an option for me.This is incorrect. It may be that your particular standalone player doesn't play DVDs with .MP2 audio (Since it's not mandatory in "NTSC land" players) - but most players will play such DVDs.

Many of the DVDs I've created with "TMPGEnc DVD Author" contain only .MP2 audiostreams (together with videostreams) - and they play perfectly on SONY, Philips, and GE standalone players, just to name a few...

[wincent]

Finally, I have managed to make my DVD with PCM audio. I mux the mpeg1 elementary stream (m1v file) and PCM audio (wav file) in an mpeg2 PS file.
Then, authordvd is able to build the DVD and it correctly detects the video as 352*288 MPEG1 and audio as PCM.

Thanks to all for your replies and advice.

No, YOU'RE not correct. MPEG audio is NOT permitted for NTSC DVD according to the specs. Yes, my player will certainly play such DVDs (I have some PAL DVDs that actually have MPEG audio soundtracks), but Scenarist will bitch about adding MPEG audio to an NTSC DVD and rightly so since the specs don't permit it.

I suppose I should have explained it better, but my point was that MPEG audio isn't valid for NTSC DVD, so that left me to AC3, PCM and DTS. Scenarist didn't allow me to use PCM with MPEG-1 video and it seemed superfluous to make a 2 channel DTS soundtrack when AC3 worked.

[Sir Didymus]

No, YOU'RE not correct. MPEG audio is NOT permitted for NTSC DVD according to the specs....


MPEG audio ALONE is not permitted...

On what I know, discs containing NTSC video are required to include at least one audio track in DD or PCM format. After that, any combination of formats is allowed. This is the way the term "optional" is used for the MPEG audio in the NTSC discs...

Most probably Scenarist - correctly - refuses to include MPEG audio as a single audio track in your NTSC project...
If you add your MPEG audio as a second track, hopefully, it should be nicely accepted...

You can easily place just one second of AC3 "silence" as a first audio track and the full MPEG audio as a second track in your project, if you are sure your standalone is happy with MPEG audio...

It's a little trick, but it should allow to build a compliant NTSC disc with "almost" only MPEG audio...

Scenarist didn't allow me to use PCM with MPEG-1 video and it seemed superfluous to make a 2 channel DTS soundtrack when AC3 worked.The initial post to this thread, as well as most of the rest of them in this thread, are neither "Scenarist"-specific nor "Scenarist"-related.

The fact of the matter is, as I said earlier - MANY, if not most, standalone players in "NTSC land" readily play video DVDs containing .MP2 audiostreams...

[raquete]

MANY, if not most, standalone players in "NTSC land" readily play video DVDs containing .MP2 audiostreams...correct! :) (and without doubts)
if the player is newer you can change the word "most" to "all" ntsc standalones.
we have to "respect" the standards of the video format and using AC3,DTS mp2 or .wav work without problems.
