  • Can ffmpeg show a progress bar ?

    4 novembre 2024, par Pawan Rao

    I am converting a .avi file to .flv file using ffmpeg. As it takes a long time to convert a file I would like to display a progress bar. Can someone please guide me on how to go about the same.

    



    I know that ffmpeg somehow has to output the progress in a text file and I have to read it using ajax calls. But how do I get ffmpeg to output the progress to the text file ?

    


  • Show all four videos as thumbnails but play them one by one using FFMPEG

    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.

    ffplay : if playing only audio or video only, show the master clock diff in status line

    Showing A-V diff has no use if there is no audio and video stream, but showing
    
the audio or video clock difference to the master clock can be useful.
