Comment:
It's working as expected. Each file reader (demuxer) runs in its own
thread, and populates that input's packet queue asynchronously at 1x in
this command. However, the concat filter only consumes each input when its
turn comes for appendage. Since both inputs are of the same duration and
readrate limited to the same speed, the 2nd input has been fully ingested
into memory when concat gets to it.
Use the realtime filter after concat instead to limit output speed.
