I have an android app where users record a video. I then add an overlay
on the video and then concatenate a 4 second video to the end of the video.
I¹m currently using two executions, as provided below. The second
(concatenate) execution TAKES FOREVER. Well over 2 minutes.
1.) is there a much faster way to do this?
2.) is there a way to execute this in a single ffmpeg command instead of
two?
ffmpeg -y
-i baselinevideo.mp4
-itsoffset 00:00:0.0000
-i overlayvideo.mp4
-filter_complex
"[1:v]scale=1280:1024[ovrl];[0:v][ovrl]overlay=eof_action=pass[outv];[0:a][
1:a]amix[outa]"
-map [outv]
-map [outa]
-vcodec mpeg4
-strict experimental
-crf
finalvideo-temp.mp4
ffmpeg -y
-i finalvideo-temp.mp4
-i concatvideo.mp4
-filter_complex "[0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]"
-map [v]
-map [a]
-strict experimental
-crf
finalvideo.mp4
