  • FFMPEG : Overylaying multiple videos with offset

    4 novembre 2014, par user1064504

    I am trying to overlay multiple videos in a split screen, with different offset (Audio, video both offset), initially I tried offsetting & overlaying like following

    avconv -i 1.webm -itsoffset 2 -s 640x480 -vf "movie=1.webm, scale=320:480 [vid2]; [vid2] overlay=0:0 [basis1]; [basis1][1] overlay=320:0" splitScreenOut.mp4

    & overlayed videos being offset by

    movie=overlay.avi:seek_point=1.4

    But this approach didn’t worked on my end, the -itsoffset offsets entire video output & seek_point wasn’t recognized by my ffmpeg build.

    Then I tried offsetting each video individually.

    avconv -itsoffset 4 -i 1.webm -c copy tmp1.webm

    & simply overlaying

    avconv -i tmp1.webm -s 640x480 -vf "[in] scale=640/3:480, pad=3.01*iw:ih [video0]; movie=tmp2.webm, scale=640/3:480 [video1];[video0][video1] overlay=(640)/3:0 [VidO1]; movie=tmp3.webm, scale=640/3:480 [video2];[VidO1][video2] overlay=(640/3)*2:0 [out]" -b:v 768k Output.webm

    The problem is all video start in split screen, from offset of first video as if individually offsetting didn’t worked.
