I am trying to create a video on my web application using images as input by the user. I am using ffmpeg currently to encode the output. However, my system becomes unresponsive each time I execute the command.
I am using exec command of php and following is my ffmpeg command.
ffmpeg -i bg2.png -i overlay1.png -filter_complex "[1:v]scale=0:0[fg]; [0:v][fg]overlay=y=-'t*w*0.1':shortest=1[v]" -map "[v]" -t 10 out.mkv
I'd appreciate if you could also share some good resources to learn more about ffmpeg on web and other alternatives.
