mpegtsmux now has support for CBR as you've noticed (the bitrate
property), so<br>
it should simply be a matter of remuxing the input file indeed.<br>
<br>
If you want to do this from the command line, the command line will
need to<br>
match the streams contained in your input file, so it's not possible
for us to<br>
give you a working pipeline :)<br>
<br>
It should more or less look like:<br>
<br>
<pre>mpegtsmux bitrate=<bitrate> name=mux ! filesink location=<path> filesrc location=<path> ! tsdemux name=demux \</pre>
<pre> demux.sink_%d ! <parser> ! queue ! mux.</pre>
<pre> <repeat above for every stream in the input file>
</pre>

<div>Hi.</div>
<div><br>
</div>
<div>I'm quite new to GStreamer. I have an input MPEG-TS stream
with a low bitrate. I need to stuff it with NULL packets to
make it higher (of course all the data like PCR must be
adjusted).</div>
<div><br>
</div>
<div>1. I was thinking about merging my original stream with the
one, filled with null packets, but with target bitrate. Is
there as some straightforward solution for that? I was
thinking about something like: <br>
filesrc location=in.ts ! ...some magic here... !
mpegtsmux bitrate=51253960 ! filesink location=out.ts<br>
</div>
<div>I have tried some variations but couldn't setup a working
pipeline so far.<br>
<br>
</div>
<div>2. Maybe there is a simpler and obvious solution I'm
missing here.</div>
