Comment (by elias tsolis):
UPDATE: Using libx264 fixed the problem. But with libx265 not.
{{{
for avii in *.mp4; do ffmpeg -i "$avii" -vcodec libx264 -vb 20M -r 30
-crf 17 -c:a copy -fflags +genpts "ab_${avii//.*}.avi" ; done;
fmpeg -fflags +igndts -f concat -safe 0 -i vids.txt -c copy -shortest
finalvideo_.mp4
}}}
