    tsdemux doesn't number its pads starting from 0, instead it names
    them according to<br>
    the PID of the streams. From the command line you can get away with
    not explicitly<br>
    naming the pads:<br>
    <br>
    <pre>demux. ! <parser> ! queue ! mux.</pre>
    <br>
    The parser is necessary for most stream types because mpegtsmux
    expects<br>
    parsed streams, check the output of gst-inspect-1.0 mpegtsmux .<br>
    <br>
    If you need to transmux TS files containing arbitrary streams, you
    should definitely<br>
    write an application. You don't have to write it in C however,
    python and rust are<br>
    also options.<br>

        <div>Hi Mathieu.</div>
        <div><br>
        </div>
        <div>Thank you for the quick anwer.<br>
        </div>
        <div>The content of the ts file is as follows:<br>
            container: MPEG-2 Transport Stream<br>
              audio: MPEG-1 Layer 2 (MP2)<br>
              subtitles: DVB subtitles<br>
              audio: MPEG-1 Layer 2 (MP2)<br>
              video: MPEG-2 Video (Main Profile)<br>
          <br>
        </div>
        <div>I have tried the example you gave, but I'm getting errors
          like:<br>
          ```<br>
          WARNING: from element /GstPipeline:pipeline0/GstTSDemux:demux:
          Delayed linking failed.<br>
          Additional debug info:<br>
          ./grammar.y(510): gst_parse_no_more_pads ():
          /GstPipeline:pipeline0/GstTSDemux:demux:<br>
          failed delayed linking pad  sink_0 of GstTSDemux named demux
          to some pad of GstQueue named queue0</div>
        <div>```<br>
          <br>
        </div>
        <div>Is that related to wrong parser I was using
          (mpegvideoparse) ? Do I really need to parse it before
          remuxing?</div>
        <div><br>
        </div>
        <div>Additionally, the example TS file is just for a testing
          purposes, in a real world I'll be getting MPEG-TS without a
          priori knowledge what kind of streams are there, therefore a
          static pipeline won't do the trick here. Is the only way to
          dynamically connect a parsers (if they are needed) to write an
          app with adding pad ad hoc as the type of stream is know?<br>

                <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>I have tried some variations but couldn't setup a
                  working pipeline so far.<br>
