How to create slideshow with FFMPEG with exact times of the slides
0
I create a slideshow as
ffmpeg
-loop 1 -t 5 -i input0.png
-loop 1 -t 5 -i input1.png
-loop 1 -t 5 -i input2.png
-loop 1 -t 5 -i input3.png
-loop 1 -t 5 -i input4.png
-i audio.mp3
-filter_complex
"[0:v]fade=t=out:st=4:d=1[v0];
[1:v]fade=t=in:st=0:d=1,fade=t=out:st=4:d=1[v1];
[2:v]fade=t=in:st=0:d=1,fade=t=out:st=4:d=1[v2];
[3:v]fade=t=in:st=0:d=1,fade=t=out:st=4:d=1[v3];
[4:v]fade=t=in:st=0:d=1,fade=t=out:st=4:d=1[v4];
[v0][v1][v2][v3][v4]concat=n=5:v=1:a=0,format=yuv420p[v]" -map "[v]" -map 5:a out.mp4
How can I modify the code with exact start and end time of each slide instead of duration.

The concat filter needs each segment to start with timestamp 0, so not possible.
