Injecting metadata from file MISP

[Fran Raga]

Hi devs

I am trying to inject a telemetry file (KLV) into a video to create a video
MISB.

After many months looking I see that only Gstreamer is able to get it.
Currently I am developing an open source project and it is already
implemented and tested the demux in real time using ffmpeg but I can create
the mux tool.
https://github.com/All4Gis/QGISFMV
What I am trying is:

D:\gstreamer\1.0\x86_64\bin\gst-launch-1.0.exe -v --gst-debug=3 -e
mpegtsmux name=mux^
 ! filesink location=C:/Users/fran/Desktop/Multiplexor/MISB2.ts^
 filesrc location=C:/Users/fran/Desktop/Multiplexor/DJI_0047_MISB_F.klv^
 ! meta/x-klv ! mux. filesrc
location=C:/Users/fran/Desktop/Multiplexor/DJI_0047.ts^
 ! video/x-h264, stream-format=byte-stream, alignment=au ! mux.

But I receive these errors:

/GstPipeline:pipeline0/GstFileSink:filesink0.GstPad:sink: caps =
video/mpegts, systemstream=(boolean)true, packetsize=(int)188


The resulting video seems to have metadata but it does not look good (the
image is corrupt i think)

Any help, suggestion about if I'm missing something, what am I doing wrong?

Gstreamer version:
gst-launch-1.0 version 1.16.0
GStreamer 1.16.0
