Complete console output is missing. This is required.
Yielded a result much smaller than expected (in size) and
when played, does not contain the contents of all the parts.
What are you trying to do exactly?
Default stream selection behavior is to select one stream of each type:

Using the info on the Concatenate Wiki page listed by Reindle,
I concocted this script and it worked perfectly; albeit, I would
have liked the output to be in HD (1920x1080).
However, every time I tried to set the size to 1920x1080, it
took forever to transcode a small video file, so I abandoned
the HD for the output.
This is the script I used:
#!/bin/ksh
infile[1]=Discourse_1_Part_1.mp4
infile[2]=Discourse_1_Part_2.mp4
infile[3]=Discourse_2_Part_1.mp4
infile[4]=Discourse_2_Part_2.mp4
infile[5]=Discourse_3_Part_1.mp4
infile[6]=Discourse_3_Part_2.mp4
O1=All_Discourses.mp4
list="concat:"
for i in 1 2 3 4 5 6; do
echo "ffmpeg -i ${infile[i]} -c copy -bsf:v h264_mp4toannexb -f
mpegts -y intermediate$i.ts"
# ffmpeg -i ${infile[i]} -c copy -bsf:v h264_mp4toannexb -f
mpegts -y intermediate$i.ts
case $i in
1) list="$list"intermediate$i.ts ;;
*) list="$list""|intermediate$i.ts" ;;
esac
done
echo list = "$list"
echo ffmpeg -i '"$list"' -c copy -bsf:a aac_adtstoasc -y $O1
ffmpeg -i '"$list\"' -c copy -bsf:a aac_adtstoasc -y $O1
For some reason, ffmpeg command line insists that the list of .ts files be
in double quotes. So, I enclosed the list first in double quotes on inside,
and then in single quotes around them.
Perhaps this is a ksh caveat???
