  • AFTER PHP-FFMpeg not converting (error with ffmpeg)

    15 juin 2018, par Magurean Dan Sergiu

    I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

    Use -h to get full help or, even better, run 'man ffmpeg'

    But when I try to convert a video file with a php script it throws me a very long error.
    PHP Code :

    <?PHP
    include($_SERVER['DOCUMENT_ROOT']."/vendors/install/vendor/autoload.php");
    $ffmpeg = FFMpeg\FFMpeg::create();
    $video = $ffmpeg->open($_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.wmv');
    $video
          ->filters()
          ->synchronize();
    $format = new FFMpeg\Format\Video\X264();
    $format->on('progress', function ($video, $format, $percentage) {
       echo "$percentage % transcoded";});
    $video
         ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
    ?>

    Error displayed :

    Unknown encoder 'libx264'

    My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

    After a few modifications

    I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.

  • Transcoding a Fast Video (think Snapchat, Instagram)

    4 juin 2018, par J DOe

    I am very new to the video world, but have noticed social media services.. particular snapchat and instagram do a great job of getting videos to load fast even on poorer connections. I know some of this is how the videos are transcoded.

    I have gathered some presets I think I should be using when transcoding with ffmpeg, but am not sure of what formats or other parts of it. I would love to hear what people think !

    ffmpeg()
       .input(remoteReadStream)
       .outputOptions('-preset fast')
       .outputOptions('-movflags +faststart')

    Other than that I am not entirely sure what else..

  • ffmpeg livestream alway stop after 160hours streamming

    2 avril 2018, par JerryJumper88

    I use ffmpeg with this code to run stream youtube 24/7 from Windows VPS. But stream alway stop after 160-167 hours and I don’t know why.

      dir/b/s "C:\Users\NASA\Desktop\ffmpeg\bin\1\*.mp4" > list.txt
    :encode video
    :loop
    for /F "delims=;" %%F in (list.txt)  DO ffmpeg -re -i "%%F" -vcodec libx264 -preset veryfast -maxrate 2500k -bufsize 3368k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 198k -ar 44100 -metadata title="" -metadata artist="" -metadata album_artist="" -metadata album="" -metadata date="" -metadata track="" -metadata genre="" -metadata publisher="" -metadata encoded_by="" -metadata copyright="" -metadata composer="" -metadata performer="" -metadata TIT1="" -metadata TIT3="" -metadata disc="" -metadata TKEY="" -metadata TBPM="" -metadata language="eng" -metadata encoder="" -f flv -s 1280x720 rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx
    goto loop

    And this is stream log. I google " Larger timestamp than 24-bit : 0xffffff9f" but nothing about this error. I contacted to admin server system, he comfirmed that has no issue connection. Then I tried again in Windows 7 and Windows server 2012, same result, still drop after 160h on youtube.
