1. Is this the most efficient way to perform this task? Could I mux the
AVC stream in test.mp4 with the AAC stream in replacement.mp4 without
first demuxing them. That is, could this all be performed in one FFMPEG
command?
No need to demux to separate files first.
ffmpeg -i test.mp4 -i replacement.mp4 -map 0:v -map 1:a -c copy
replaced.mp4
This will also be devoid of the PTS msgs, which were due to your use of
.h264, which is a raw stream without timestamps.
