I would have expected that you, at least, read the current docs.

[jens1o]

You need to install ffmpeg, too.

[rohitgaidhane]

[rohitgaidhane]

i have installed ffmpeg using cli.but same issue occurs.

[jens1o]

is it in your PATH?

[rohitgaidhane]

[jens1o]

what happens when you execute ffmpeg in the same folder your php-files are in?

[rohitgaidhane]

i m able to execute ffmpeg any where in my pc using cli but if i want to execute this using php so error ouccers

[jens1o]

Can you ensure PHP has proper permission and may open new processes?

[rohitgaidhane]

which permission can you plz explain?

[rohitgaidhane]

`<?php

require 'vendor/autoload.php';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('rj.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\X264(), 'export-x264.mp4')
// ->save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
// ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');

$format = new FFMpeg\Format\Video\X264();

$format->on('progress', function ($video, $format, $percentage) {
echo "$percentage % transcoded";
});

$format
->setKiloBitrate(1000)
->setAudioChannels(2)
->setAudioKiloBitrate(256);

$video->save($format, 'video.mp4');
?>`
this is my code

[rohitgaidhane]

`

$currentPath = $_FILES['video']['tmp_name']; if(exec("ffmpeg -i tareaditi.mp4 -b 1500k -minrate 1000k -maxrate 1100k -bufsize 1835k aa112.mp4")) { echo "success"; } else{ echo "fail"; }

}
?>`

in this way its working

[jens1o]

Unknown encoder 'libfaac'

Try using $format = new FFMpeg\Format\Video\X264('aac'); instead of $format = new FFMpeg\Format\Video\X264();

This issue will be resolved with 1.0.

[rohitgaidhane]

ok i will try.thanks for response

[rohitgaidhane]

thanks its working...
and one thing ,is this code work on my linux based vps hosting

[jens1o]

That's something you need to try out yourself ;)

Please make sure that your hosting provider allows video encoding on shared-hosting machines ;)

[rohitgaidhane]

okkkk.Thanks you help me lots on this.

[kavin-90]

to get rid of PATH issue insert FFMPEG , PHP, NGINX, APACHE,WAMP bin path into PATH list so no issue will return but after insert path into env you have to restart cmd to apply new changes xD

[rohitgaidhane]

can you plz tell me how to reduce framerate?

[rohitgaidhane]

as i found that reducing video size is not only thing i needed i also needed to reduce video framerate

[jens1o]

Please read the README. Although the documentation is rather bad, it is there and describes exactly what you need! It is not possible for me to provide 1:1 support. Thanks!

[rohitgaidhane]

i got this code but how to implement this ?

$video
->filters()
->resize($dimension, $mode, $useStandards)
->framerate($framerate, $gop)
->synchronize();

i m stucked here plz help me out there?

[jens1o]

Please learn some basic PHP. lol.

[rohitgaidhane]

ok..,thanks
