<div dir="auto">If you use Mplex for muxing then Mplex
will abort with a message that it cannot recognize the

for Mplex to mux an LPCM audio stream, but the file
must have the extension "lpcm". You can verify this by
renaming the audio file in the DVDStyler cache folder
and give it the "lpcm" extension. Then feed the video
and this renamed audio stream to Mplex for muxing, and
you will get a perfect MPEG2 file with PCM audio.<br>

Well folks(?),<br>
<br>
No responses but I appear to have made some headway, which
I'll share here in case someone's out there somewhere
scratching their own head over this.<br>
<br>
The problem seems to have to do with dvdauthor's STC
discontinuity at the chapter points when it's fed one file
per chapter; the initial pts/dts values are reset, and this
somehow throws things off during playback, even if audio and
video endpoints are perfectly aligned.<br>
<br>
If the whole titleset is mplexed as one mpg and then
dvdauthored with chapter- point offsets, the gaps
disappear. Also, if the chapter points aren't aligned to
GOP boundaries, dvdauthor will do it anyway and shift them
backwards.<br>

signed with the constituent bytes in big-endian (most

such samples are padded at the lsb end so that they

Not a direct respons, but I think I have come a step forward via a
five years old ffmpeg bug report:<br>
<blockquote><a class="moz-txt-link-freetext" href="https://trac.ffmpeg.org/ticket/6782">https://trac.ffmpeg.org/ticket/6782</a><br>
Doesn't produce MPEGPS-MPEG-2-LPCM compliant output (-target, -f
dvd, -f vob). Buffer underflow appear.<br>
pcm_dvd added; mpegps -target removed<br>
<br>
</blockquote>
There is obviously a deticated "pcm_dvd" codec for ffmpeg,
correspondingly to the later "pcm_bluray".<br>
So I verified this on my ffmpeg 5.1.2 built from Packman for
Tumbleweed and found:<br>
<br>
<blockquote>ffmpeg -hide_banner -codecs | egrep "pcm_bluray|pcm_dvd"<br>
DEAI.S pcm_bluray PCM signed 16|20|24-bit big-endian
for Blu-ray media<br>
DEAI.S pcm_dvd PCM signed 20|24-bit big-endian<br>

I looks like DeVeDeNG version 4.17 possibly doesn't support pcm_dvd
yet. To get this clarified I have written to the author to try to
get this clarified.<br>
My first impression of this program is that I got taste for its
simplicity and straight forward use, yet relative comprehensive
behind the buttons.<br>

With DeVeDe I managed to create the video DVD
structure and ISO, and it offered to burn the
iso with K3b automatically,<br>
With its Property/Misch buttons the selection in
the middle offered:<br>
*Repack audio and video without reencoding
(Useful for VOB files)<br>
<br>
The problem is that the Audio (PCM) disappeared
from the dv28.mpg input file<br>
