    18 juillet 2018, par p.jadhav

    I want to show four videos as thumbnails but play them one by one (video1 plays first then video2, etc).

    I tried this

    String[] cmd={"-loop","1","-t","36","-i","/storage/emulated/0/Download/trasprent_bg.png","-i","video1.mp4","-i","video2.mp4","-i","video3.mp4","-i","video4.mp4","-i","collage_1.png","-filter_complex","[1:v]scale=500:500,crop=266:266[tfg];[2:v]scale=500:500,crop=266:266,setpts=PTS+9/TB[bfg];[3:v]scale=500:500,crop=266:266,setpts=PTS+18/TB[threefg];[4:v]scale=500:500,crop=266:266,setpts=PTS+27/TB[fourfg];[5:v]scale=-1:-1[colage];[0:v][tfg]overlay=2:2:eof_action=pass[o1];[o1][bfg]overlay=272:2:eof_action=pass[o2];[o2][threefg]overlay=2:272:eof_action=pass[o3];[o3][fourfg]overlay=272:272:eof_action=pass:shortest=1[o4];[o4][colage]overlay=0:0","-an","videoCrop.mp4"};

    which plays the videos one by one but only shows the playing video with nothing showing for the other videos :

    Using above command play video as below.
    first video play,second video play,third video play

    I want to display all four output videos but play them one by one like below.

  • How can I change slice_type which is show in Elecard stream analyzer using ffmpeg ?

    10 octobre 2018, par Tooraj Jam

    I’m not ffmpeg and encodding expert and am trying to encode a MP4 file to MPEG-4 h264 .ts file.

    When Elecard stream analyzer is analyzing my result .ts file, it shows slice_type = 7 for all of i-frames as you can see in the attached screenshot.

    How can I change all these to slice_type = 2 ?

    My ffmpeg command :

    -i Source.mp4 \
    
-filter:v 'setpts=0+PTQ-STARTPTS' -metadata:s:v:0 start_time=0 \

    Environment：Windows64+Ngg-rtmp-static+Ffmpeg-static+Java1.8
