At the moment I am making a slideshow like the following:
zoompan=zoompan=d=3:fps=.333:s=1280x960,framerate=25:interp_start=0:interp_end=255:scene=100
ffmpeg -y \
-i %03d.jpg \
-i ${audio} \
-to $to \
-vf ${zoompan} \
-pix_fmt yuv420p \
${outputFile}
Until now I found audios that had the right length, but now I need to
put several audios together for the generated video.
I could create an audio from several audios every time.
A slightly better option would be a variant of:
-itsoffset 10 -i audio1.mp3 -itsoffset 15 -i audio2.mp3
But is there a way to just let the audios be put after each-other?
You can use the concat filter.
ffmpeg -i audio1.mp3 -i audio2.mp3 -lavfi [0][1]concat=n=2:v=0:a=1 out.mp3
v=0 is important because the default is v=1.

This does not work:
-i ${audio1} \
-i ${audio2} \
I only get the first audio.
But the same happens with -itsoffset I am afraid.
I used:
ffmpeg -y -i %03d.jpg -i /home/cecil/Audio/YouTube/Habanera_by_Bizet.mp3
-itsoffset 120 -i /home/cecil/Audio/YouTube/Wedding_Invitation.mp3 -vf
zoompan=d=3:fps=.333:s=1280x960,framerate=25:interp_start=0:interp_end=255:scene=100
-pix_fmt yuv420p sander2.mp4
I only here the first audio.
