  • ffmpeg - how to use pipe with amovie parameter ?

    19 février 2018, par user1347009

    I am looking for a solution to overlay to mp3 files in which the longer one will be played in the background and the smaller one will continue to play like a loop with that.
    My current code is working without pipe :

    ffmpeg -i 'longer.mp3'  -filter_complex "amovie='small.mp3:loop=999'[s];[0][s]amix=duration=shortest" new.mp3

    This code works like a charm but what i want to achieve is this :

    curl "any-url-to-api-to-audio-file" | ffmpeg -i 'longer.mp3'  -filter_complex "amovie='pipe\:0:loop=999'[s];[0][s]amix=duration=shortest" new.mp3

    This code is not working and its giving me error as well,

    The smaller one will be repeated like a loop till the longer one play.

    Please tell me how can i do that ?

  • ffmpeg concat two video and add watermark after concating video give me blank mp4 file on server but in local working perfectly why ?

    i have two video i want to concat them and then add watermark to them but after command run give me blank mp4 file on server but in local working perfectly and on server two video concat perfectly but after that code is not running.

    My code is as follows.

    $videoFileName = rand('111111', '999999').'_'.time().'.'.$request->file('video1')->getClientOriginalExtension();
       $intermediateVideo1 = rand('1111111', '9999999').'_'.time().'.ts';
       $intermediateVideo2 = rand('1111111', '9999999').'_'.time().'.ts';
       $concatVideoFileName = rand('111111', '999999').'_'.time().'.'.$request->file('video1')->getClientOriginalExtension();

       exec('ffmpeg -i '.$request->file('video1').' -c copy -bsf:v h264_mp4toannexb -f mpegts '.$intermediateVideo1);
       exec('ffmpeg -i '.$request->file('video2').' -c copy -bsf:v h264_mp4toannexb -f mpegts '.$intermediateVideo2);

    I don't have deeper experience with ffmpeg conversions and codecs. It seems to me that this is a frames related problem. Do you have a clue why does it fail ? What options should I use in ffmpeg command to solve this ? Thanks for any help.
