Hello I tried following your method
ffmpeg -i intro.mp4 -i video.mkv -filter_complex "[0:v][0:a][1:v][1:a] concat=n=2:v=1:a=1 [outv] [outa]" -map "[outv]" -map "[outa]" out.mp4
And this is the result
Input link in0:v0 parameters (size 960x1280, SAR 16:9) do not match the corresponding output link in0:v0 parameters (720x720, SAR 16:9)

The first video is made with app intro maker, the second video is made with joining audio and 1 image (using ffmpeg too
ffmpeg -loop 1 -i image.jpg -i audio.ogg -preset ultrafast -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv440p -shortest mentahan.mp4),
Before I concat videos using this
ffmpeg -f concat -i part3.txt -c copy out.mp4
But the uploaded result cant be played from telegram, but can be played with android video player
can you help me?
