PHP-FFMpeg: Encoding Failed

I am running the basic script provided in the documentation. This is on a linux server. I am using a .mov file for testing. The frame is generated but the encoding fails with the following error.

exception 'Alchemy\BinaryDriver\Exception\ExecutionFailureException' with message 'ffmpeg failed to execute command '/usr/bin/ffmpeg' '-y' '-i' 'Algonquin elevators 4.mov' '-f' 'webm' '-vcodec' 'libvpx' '-acodec' 'libvorbis' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' 'export-webm.webm'' in /var/www/aims/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/ProcessRunner.php:100 Stack trace: #0 /var/www/aims/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/ProcessRunner.php(72): Alchemy\BinaryDriver\ProcessRunner->doExecutionFailure(''/usr/bin/ffmpe...') #1 /var/www/aims/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/AbstractBinary.php(209): Alchemy\BinaryDriver\ProcessRunner->run(Object(Symfony\Component\Process\Process), Object(SplObjectStorage), false) #2 /var/www/aims/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/AbstractBinary.php(137): Alchemy\BinaryDriver\AbstractBinary->run(Object(Symfony\Component\Process\Process), false, Array) #3 /var/www/aims/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Media/Video.php(155): Alchemy\BinaryDriver\AbstractBinary->command(Array, false, Array) #4 /var/www/aims/ffmpeg-test/index.php(37): FFMpeg\Media\Video->save(Object(FFMpeg\Format\Video\WebM), 'export-webm.web...') #5 {main} Next exception 'FFMpeg\Exception\RuntimeException' with message 'Encoding failed' in /var/www/aims/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Media/Video.php:165 Stack trace: #0 /var/www/aims/ffmpeg-test/index.php(37): FFMpeg\Media\Video->save(Object(FFMpeg\Format\Video\WebM), 'export-webm.web...') #1 {main}

The ffmpeg is working good through cmd line, also it works if I run shell_exec

shell_exec("ffmpeg -i Algonquin elevators 4.mov output.webm &");

If on a mac - Install FFMpeg like this

brew reinstall ffmpeg --with-faac --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

Remove the older version first.

run it manually, it’s probably about reading the passfile

cool you managed to do the job.

I’ll work on a proper debugger soon (see #94), but you can have an insight about what’s wrong with such code:

$ffmpeg = \FFMpeg\FFMpeg::create();
$ffmpeg->getFFMpegDriver()->listen(new \Alchemy\BinaryDriver\Listeners\DebugListener());
$ffmpeg->getFFMpegDriver()->on('debug', function ($message) {
    echo $message."\n";
});
$video = $ffmpeg->open($source);
$video->save(new \FFMpeg\Format\Video\X264(), $target);
