Hi All, How to use FFmpeg video overlay function to add image logo to a MP4 video where overlay positions shall taken from an external input.
Following is the command I am using to apply a logo to a video file ffmpeg -i input.mp4 -i image.png -filter_complex \ "[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" -c:a copy output.mp4 Say when the input is 1 the logo need to be placed on top left corner etc. Does the overlay position can be changed on the fly based on input from the file? Say for input file content given below cat input.txt 1 2 3 4 I need to move the logo to other positions after the 20 sec duration is elapsed. Is this is supported in FFmpeg command line or libavformat? Used FFmpeg version is 2.6.2 Thanks, SetV
