MP4 to WebM - Encoding Failed

[tuckerdarby]

Hello,

I've been attempting to convert MP4 videos to WebM, but am having issues. When I try this with native FFMpeg it works fine, but fails when using this Laravel plugin.
Here is a snippet of my code:

    $webm_format = new FFMpeg\Format\Video\WebM();
    $video->save($webm_format, '/var/www/html/laravel/storage/'.$webm_target_name);

And here is my stack trace:

Right before this I am doing an X264 encoding with audio codec of "libfdk_aac", and it works fine.

I have also noticed this does not happen with all videos. (Works with videos originating from iPhones, but not Androids)

Let me know if there's more information I can provide.

Help is greatly appreciated.

The save method only requires a filename, you should call the inFormat method on the Exporter:

$video = FFMpeg::open('my_movie.mov');
$webm_format = new FFMpeg\Format\Video\WebM();

$video->export()
    ->inFormat($webm_format)
    ->save('my_movie.webm')

Check out the README for more examples.

Thank you for the quick reply. We've decided to drop WebM support, so this isn't much of an issue anymore.

However, when I tried out your examples with export(), I get the error:

PHP error: Call to undefined method FFMpeg\Media\Video::export() on line 1

This could be user error or a problem with the version of the plugin I have. Just thought I'd post a follow up though.
