Re: spumux issues

Not using dvdunauthor was the issue.  I've always done that before and it didn't even occur to me that that
might be the issue.  The reason I didn't do it this time, though, was that dvdunauthor just gave up when I
tried to use it.  Oh, well, now I know.

Thanks again for all the help.

dvdunauthor is heavily dependent on libdvdread to do the decoding of
DVD-Video structures. Unfortunately, the way that library is written,
instead of returning proper error codes, it wants to print error
messages itself. Which I can cope with, except when it doesn’t even do
that, just returns NULL or something. dvdunauthor exits when it sees
this, assuming that libdvdread has already displayed a message
indicating what went wrong. If it didn’t, then you are just left
wondering what was going on.

Are non-menu stills with audio possible?

Is it possible to have a still with audio as a title item?

I am trying to create an NTSC DVD that contains audio with a still image as the video.  I've created the still
from an image of 720x480 resolution via jpeg2yuv, mpeg2enc and mplex.  No errors from dvdauthor when I
build the DVD, but when playing it, the still remains onscreen after the audio finishes; it doesn't return
to/call the menu. I have to press the menu button on my remote to return to the menu.  I've also tested this
with 15-second audio snippets (instead of a full-length song) and the problem still exists.

I intend to have many such titles (among other content) on my DVD and would like to keep the file size of this
particular media down.  I know this (stills with audio) works for SVCD...

dvdauthor version: 0.6.14
mjpegtools version: 1.9.0-r1

I've used the following commands to convert an image to a still and mux it with the audio:

jpeg2yuv -j lat.jpg -f 29.97 -I p | mpeg2enc -a2 -f8 -o lat_img.m2v
Output: http://paste.pocoo.org/show/449195/

and then:
mplex -f8 -o DONE/lat.mpg lat_img.m2v lat.ac3
Output: http://paste.pocoo.org/show/449196/

DVDAuthor XML:
<dvdauthor dest="dvd" jumppad="no">

<vmgm>
</vmgm>

<titleset>

Absolutely.

This is extremely ancient. Doesn’t your distro offer a more up-to-date
build?

I’m not familiar with mjpegtools (I prefer FFmpeg), but I don’t see
where you specify the duration of the video. That “Number of Frames -1”
looks a bit worrying to me. Could it simply be the video duration is
ridiculously long?

> Note: I am not interested in moving to any additional tools

I would recommend using FFmpeg to generate the video—it has simpler
options for setting format, duration etc. Particularly with my wrapper
slidify script <https://github.com/ldo/slidify>.
