Webm convertion Code

i think you should not use ffmpeg.exe ,,, you should use /usr/local/bin/ffmpeg or only ffmpeg — Mohammad Alabed, May 19 '15 at 14:22
You can run shell commands like that: `$result = \`ffmpeg -i "blank.mp4" -acodec libvorbis -b:a 96k -ac 2 -vcodec libvpx -b:v 400k -f webm -s 384x216 "blank.webm"\`;` and `$result` contains the output generated by the command. — TiMESPLiNTER, May 19 '15 at 14:23

i have put like this, $result = `"$ffmpeg" -i "$video" -acodec libvorbis -b:a 96k -ac 2 -vcodec libvpx -b:v 400k -f webm -s 384x216 "$webmpath"`; — intrepid web, May 19 '15 at 14:34

Does the unscripted `ffmpeg` command work when you manually run it in a console? — llogan, May 19 '15 at 16:26

require 'vendor/autoload.php';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('video.mp4');
$video
    ->filters()
    ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
    ->synchronize();
$video
    ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
    ->save('frame.jpg');
$video
    ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
    ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');
