The reason that I

stream related to
timing, is because
this should be
possible to <b>add</b>
or import to an
existing video

need to re-encode.
It should also be

There are written several
articles and answers to forum
topics about adding soft
subtitles to video. <br>
My best but only partly working
attempt so far, is by applying
this solution on StackOverflow:
<br>
<br>
<i>Use ffmpeg to add text
subtitles: NOTE: This solution
adds the subtitles to the
video as a separate optional
(and user-controlled) subtitle
track.<br>

<div dir="auto">isn't this command just
uses external srt and not muxed one?</div>
</div>
</blockquote>
<br>
Yes, I think you'r right, and I wondered a
bit about it, but had no keyboard shortcut
for ffplay to test switching subtitles on
and off.<br>
<br>
So, afterwards I was more convinced - and
fooled, when both Gnome Media player (Totem)
and SMplayer automatically displayed the
subtitles.<br>
But that was when the srt subtitle file had
the same name as the mpg video file and was
located in the same directory. But this
worked as well with the first mpg file (1).<br>
<br>
The command line "vlc dvd.mpg dvd.srt" also
worked with audio. Why both VLC and MPlayer
lost the audio with the srt muxed mpg file I
have no idea about.<br>
-----------------------------<br>
<br>
From your first reply: <br>
<blockquote>rendering text as palletized
picture and then muxing it into mpeg
stream is unavoidable step,as far as I
understand.<br>
But may be those DVD creation guis can do
srt => dvd_sub conversion for you ?<br>

<br>
Andrey mentioned the "srt2vobsub" program,
which seems to the same as the "srt2vob"
script for DVD and "2dsub" for BD vobsub<br>

<br>
<br>
And from my reference to g-raffa: <br>
<blockquote>PRE-RENDERED SUBTITLES<br>
they are added (muxed) to the video
stream as images with minimal information
but can be separated (demuxed) when
needed. They are used in DVDs and
they can be turned on and off.<br>
Most DVD authoring applications are
capable of transcoding external subtitles
to pre-rendered subtitles and of muxing
them to the video stream.<br>

Now I have tried both ASII, UTF-8 and ISO-8859-1 encodings, but
still DevedeNG exists with error, also already when trying the
Preview button.<br>
DevedeNG 4.17 has a newer gui and I cannot see there is any
Advanced button for Mencoder.<br>
I also tried to add a pure dv clip and a srt subtitle file in
Devede, and got the error again.<br>
<br>

<br>
Checking the character set of my srt subtitle file:<br>
<blockquote><font face="Courier New, Courier, monospace">file -bi
dvd.srt</font><br>
<font face="Courier New, Courier, monospace">text/plain;
charset=us-ascii</font><br>

Looks like I am not able to change the charset to utf-8<br>
