PHP-FFMpeg allow multiple input

Question

I want to reproduce this command

ffmpeg -i image.png -i audio.wav -acodec libvo_aacenc -vcodec libx264 output.flv

with PHP-FFMpeg

I can't find in documentationa way to add multiple input file (-i image.png -i audio.wav)

Answer 1

I found a simply solution (hack): to add the second input as a filter

$video = $this->ffmpeg->open($imageSource);
$video->addFilter(new SimpleFilter(['-i ', $audioSource]));

it seems to works as expected
