L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.

  • How convert High bitrate mp3 to lower rate using ffmpeg in android

    23 March 2018, by Android Team

    We want to convert 320kbps mp3 file to 128kbps mp3 so currently we are using below ffmpeg command but its not working.

    ffmpeg -i input.mp3 -codec:a libmp3lame -qscale:a 5 output.mp3

    Result:-the output bitrate same as input mp3.

    And we are following the FFmpeg Encoding guideline for that here is the link :- https://trac.ffmpeg.org/wiki/Encode/MP3

    so please suggest any solution.

  • ffmpeg works fine most of the time in java except for this command (merging), and this command works fine directly in terminal

    14 May 2014, by Ron I

    When I run this from the command line it works (merges two videos side by side):

    /usr/local/bin/ffmpeg -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test.mov -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test1.mov -filter_complex "[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w" /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/merged.mov

    However, when I run it in java, I get this from the console:

    [AVFilterGraph @ 0x7fd44ad00440] No such filter: '"'
    
Error configuring filters.

    here is the text I am returning (copied directly) which is what I am sending to be executed. It is exactly the same, except I use the escape character before the quote symbol, so a " becomes \":

    "/usr/local/bin/ffmpeg -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test.mov -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test1.mov -filter_complex \"[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w\" /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/merged.mov";

    All other ffmpeg tests have worked except this.... (the only one where I use a " character)

    Can anyone figure it out?

  • Unable to use FFMPEG for speed change for video file

    23 December 2019, by Sachin Harne

    I am working with a video file where I need to change the speed of the video, slow-motion as well as fast-motion the video. I tried using the commands below but none of those are helping me out.

    String cmd = "-i " + inputFilePath + " " + "-filter:v" + " " + "setpts=0.5*PTS" + " " + outputPath;

    String cmd = String.format("-i " + filepath + " -filter:v "+ "\"setpts=2.0*PTS\"" +  outputPath);

    String cmd =  "-i " + filepath + " -vf " + "\"setpts=(1/60)*PTS\" " + outputPath;

    String cmd = String.format("ffmpeg -i " + filepath + " -filter:v " + "\"setpts=PTS/60\" " + outputPath);

    Getting the error message as below:

    Unrecognized option ’i /storage/emulated/0/Movies/video/video_20191223184836613013111.mp4 -vf "setpts=(1/60)*PTS" /storage/emulated/0/Movies/video/finalVideo_724.mp4’.

    Error splitting the argument list: Option not found
