  • ffmpeg terminates without any output

    11 septembre 2012, par Khan

    I am using ffmpeg to convert a video file to mp4. here is my code

       echo "converting ".basename($src)." --- to --- ".basename($dest).".mp4...<br />";
    $command = FFMPEG.&#39; -i &#39; . $src . &#39; -sameq -strict -2 -vcodec libx264 -ar 22050 -y &#39; . $dest.&#39;.mp4 2>&amp;1&#39;;   //
    echo $command.&#39;<br />&#39;;

    exec($command,$output,$status);
    echo &#39;<pre>&#39;,join(&#39;<br />&#39;,$output),&#39;</pre><br />&#39;;

    if($status == 0) {              // Success
       echo &#39;Successfully converted to MP4!<br />&#39;;
    } else {
       echo $status."<br />failed<br />";
    }

    The code works fine on my localhost (Windows 7 + wamp).. But on live server , only $command is echoed.. and script is terminated. The output file is generated but it is only 4.5MB (it should be around 17 MB) and not complete... and sometime I get the following output..

  • ffmpeg javacv audio - integrate audio into video javacv

    16 juillet 2014, par Cyril Lequeux

    I’ve looked for this issue since a while but I didn’t find out any solution...
    I want to create a video from pictures with javacv (great, it works). But now I want to put in a sync way audio into my video. I heard I had to make a byte array with the sound data and then record() according to the audiobitrate/8 = audiobyterate but i didn’t find a simple sample...I’m not the first asking this question but all the same questions are still unanswered

       IplImage Image = cvLoadImage("data/photo.jpg");
       FrameRecorder recorder = FFmpegFrameRecorder.createDefault("out.avi", 1920, 1080);
       recorder.setVideoCodec(AV_CODEC_ID_MPEG4);
       recorder.setFrameRate(30);
       recorder.setFormat("avi");
       recorder.start();
           for(int s=0; s&lt;10; s++){
               for(int i=0; i&lt;30; i++){
                   recorder.record(Image);
    //Here I want to record my music.mp3 stream
               }
           }
           recorder.stop();

    Please help me, I’m desesperate :p
    Ps : I’m using javacv 0.3 FFMPEG 1.06 OpenCv 2.4.3

  • FFMPEG - convert video without losing resolution

    29 octobre 2015, par Srh

    I am using ffmpeg to convert mp4 video from youtube. The video is HD 1080. When I convert it to mpeg2video, the video loses its sharpness, regardless of the -s 1920x1080 parameter. How can I convert the video without losing picture sharpness ? The command I use is :

    ffmpeg -i BBB.mp4 -vcodec mpeg2video -s1920x1080 -acodec copy -f mpegts BBB.ts
