So this part

 filesrc location=DJI_0047_MISB_F.klv ! meta/x-klv ! mux.

isn't going to work like that. meta/x-klv is supposed to be a parsed
format with one buffer per KLV chunk. People usually don't feed this in
from a file, but inject it live via an appsrc or such as they go along.
So you would need a klv parser here.

Then this part

 filesrc location=DJI_0047.ts ! video/x-h264, ... ! mux.

that's not really how things work. The file looks like it is an MPEG-TS 
stream. So if you want to get to the video data inside that MPEG-TS
file you need to demux it, with the tsdemux element. So something like

 filesrc location=foo.ts ! tsdemux ! video/x-h264 ! mux.

might work, but usually one would put in a parser as well, in this case
h264parse:

 filesrc location=foo.ts ! tsdemux ! h264parse ! mux.

Cheers
 Tim
