I need to insert the following packet, which contains KLV metadata to a Program Stream file. Note this packet has a SCR of 00:00:00.000, as I wanted the metadata at the start of the file, and the KLV metadata is the same as the Day Flight example found https://samples.ffmpeg.org/MPEG2/mpegts-klv/. I’ve also padded it (0x00 0x00 0x01 0xBE) to be 2048 bytes long, as the standard MPEG-PS packet size.

I have ran the command ffmpeg -i Day Flight.mpg -vscale 0 -f mpeg2video output-MPEG-PS.mpg to convert the Day Flight video to be in a MPEG-PS format. How can I insert that above KLV packet to the output MPEG-PS file, and not corrupt the video.
