I am working with Laravel 5.3
In my localhost works fine
_When I uploaded to my shared host fails_
My binaries has +x permissions

Encoding failed in file
/php-ffmpeg/src/FFMpeg/Media/Video.php
line : 178

In my server, I have my files in my web dir

` $ffmpeg = FFMpeg::create([
'ffmpeg.binaries' => '/home3/myuser/public_html/myproject/binvideos/ffmpeg',
'ffprobe.binaries' => '/home3/myuser/public_html/myproject/binvideos/ffprobe',
'timeout' => 9800, // The timeout for the underlying process
'ffmpeg.threads' => 12 // The number of threads that FFMpeg should use

        ]);

        $videoCodec = $ffmpeg->open(public_path("uploads/targets/$videoName"));
        $format = new X264();
        $format->setAudioCodec('aac','libmp3lame');
        $videoCodec->save($format,$newVideoPath);

`

Please check wether the php executing process has also these permissions and they are not exclusive to the root user.

[marcoapferegrino]

Yes is writing the file because it appears in the directory I wrote but for some reason it fails when is encoding, or at least that said the issue.
FFMpeg\Media\Video->save(Object(FFMpeg\Format\Video\X264), '/home3/myuser...')

How can I check those because in local I didn't need it

[jens1o]

Check to which user the directory owns(and maybe overwrite it to the php user)

[marcoapferegrino]

My web user is the same as the owner in my web dir and the dir where I have the binaries.
I remember you, I have binaries inside my web dir because I can not put them in usr/bin or usr/local/bin

[jens1o]

Could you post the exact error message? Usally, there is a command inside the exception message. That's interesting

[marcoapferegrino]

This is all I have, I tried get something more but is all.

            {$e->getFile()},
            {$e->getLine()},
            {$e->getCode()}:::::::

[jens1o]

But this can't be the full stacktrace... Also, there should be a exception included("previous")

[marcoapferegrino]

Oh sure here I had

[jens1o]

okey, could you try to execute the command on your own(and show us the output)?

[jens1o]

Well, that's a ffmpeg problem(and I don't know how to fix it; sorry!) and not one with the library. Maybe try a different file? And please update your ffmpeg, since it is outdated.

[marcoapferegrino]

Ok I will try it. Is weird because in my local environment is working. I really appreciate your help. Thanks

[jens1o]

Please let us tuned.

[jens1o]

After some research, most people suggested that you're only using one thread(when your server forces code to be single-threaded), do so by replacing

$ffmpeg = FFMpeg::create([
    'ffmpeg.binaries' => '/home3/myuser/public_html/myproject/binvideos/ffmpeg',
    'ffprobe.binaries' => '/home3/myuser/public_html/myproject/binvideos/ffprobe',
    'timeout' => 9800, // The timeout for the underlying process
    'ffmpeg.threads' => 12 // The number of threads that FFMpeg should use
]);

to this:

$ffmpeg = FFMpeg::create([
    'ffmpeg.binaries' => '/home3/myuser/public_html/myproject/binvideos/ffmpeg',
    'ffprobe.binaries' => '/home3/myuser/public_html/myproject/binvideos/ffprobe',
    'timeout' => 9800, // The timeout for the underlying process
    'ffmpeg.threads' => 1 // The number of threads that FFMpeg should use
]);

let me know wether this works for you.

Hi, tried with one thread and I got this error. My Binaries works are the same as I use in local and works and are the lasts version, also the videos I test have no problem, in my local works fine. any idea?.

[jens1o]

I don't know to be honest. Let us know when you found something out, it could be useful for others, too.

[marcoapferegrino]

SOLVED I guess

I already solved just changing this line

$format->setAudioCodec('aac','libmp3lame');
by this one
$format->setAudioCodec('libmp3lame');

Can I not add two codecs? or is in array param?

[jens1o]

No, you can't do that(it's not possible by ffmpeg, therefore not by this lib). If you want to do 2 exports, you need to create two formats and save both.

[marcoapferegrino]

Oh, so, at end it was my typo I really feel like a fool, sorry to waste your time dude I did not notice

[jens1o]

Hey, no problem. We'll update the implementation and check that this won't happen ever again. It's fine. You'd actually found a bug(we should check that).
