Description
Using the files from here:
https://ahiru.eu/~vivia/parts1to7.tar
$ gst-launch-1.0 splitmuxsrc location="part*.flv" name=d d.video ! queue ! h264parse ! matroskamux name=m ! queue ! filesink location=allparts2.mkv d.audio ! aacparse ! queue ! m.
This works fine.
[fish syntax warning]

The video codec tag 8 is completely bogus, the file is H264, like all the previous ones. gst-discoverer and gst-play agree with me, as well as the first example.
$ gst-launch-1.0 multifilesrc location="part%02d.flv" start-index=2 stop-index=7 ! queue ! flvdemux name=d d.video ! queue ! h264parse ! matroskamux name=m ! queue ! filesink location=allparts1.mkv d.audio ! aacparse ! queue ! m.
The resulting file is valid, but it only contains the contents of part02.flv .
