<p>So according to the docs located here
<a href="https://trac.ffmpeg.org/wiki/Concatenate" rel="nofollow noreferrer">https://trac.ffmpeg.org/wiki/Concatenate</a><br />
<strong>section: Changing playlist files on the fly</strong></p>
<p>it says you can do this:</p>
<blockquote>
<p>Now you can change the looping clip by a simple move command:</p>
</blockquote>
<pre><code>mv next_clip.mxf dummy.mxf
</code></pre>
<p>I cant find any examples on the web of how this works.</p>
<p>I will test it some more but i cant seems to get this to work, I added it on the last line in place of where i would normally put the next text file to open.  but it just kept cutting off.</p>
<p>I am assuming that it would cut off because that once it loads up the txt file, it cant be changed.</p>
<p>I have seen reference to such things as &quot;outpoint and inpoint&quot;  but can not find any info on that either.</p>
<p>can someone point me in the direction to all the commands i can put into the txt file when using the concat demuxer.  i would like to learn what all i can do.</p>

thanks, so @gyan it is BEFORE last video in txt file plays, or is it once txt file is loaded there is no going back?    I was gonna go with the old method of  'files  video.mp4' and then the next list on the last line. file 'next.txt' ... if i stuck with that model can that last line "next.txt" be changed to say "two.txt" once the first txt file is loaded into ffmpeg?
