user38282: I have two videos, that i want to concatenate side by side but second one should play after the first one. If the video is not playing, thumbnail should be shown
Below is the example that i want to achieve using ffmpeg https://twitter.com/sunmor2901/status/1520024861619658752

user38050: ffmpeg -i left.mp4 -i right.mp4 -i -filter_complex "[1:v]tpad=start_mode=clone:start_duration=5[rvideo];[1:a]adelay=5s:all=true[raudio];[0][rvideo]hstack[vout];[0:a][raudio]amix[aout]" -map "[vout]" -map "[aout]" output.mp4
You have to manually set the delay of the second (right) video from the 5 seconds in the example.
