Unable to probe output for concatenated videos

[daviidy]

Hello, I want to concatenate many videos with ffmpeg. I'm using Laravel 7.7.1 and i'm running on PHP 7.4 Here is my code

`public function joinVideos(Recording $recording) { $disk = FFMpeg::fromDisk('public'); $video1 = $disk->open('video1.mp4'); $video2 = $disk->open('video2.mp4'); $output = $disk->open('test.mp4');

     $video1->concat([
         $video1->getPathfile(),
         $video2->getPathfile(),
     ])->saveFromSameCodecs($output->getFullPath(), true);

    return redirect()->back()->with('status', 'Success');
}`

But i'm getting this error: Unable to probe C:\Users\DELL\Documents\workspace\repetbox\storage\app/public\test.mp4

I've already put the right paths to ffmpeg and ffprobe binaries

I've rewritten the package and support for concatenation is included. Could you test the v7 branch? Almost no breaking changes except for some filter stuff in HLS exports.

https://github.com/pascalbaljetmedia/laravel-ffmpeg/tree/v7

composer require "pbmedia/laravel-ffmpeg:v7.x-dev"

<?php

// without transcoding
FFMpeg::fromDisk('local')
    ->open(['video.mp4', 'video2.mp4'])
    ->export()
    ->concatWithoutTranscoding()
    ->save('concat.mp4');

// with transcoding
FFMpeg::fromDisk('local')
    ->open(['video.mp4', 'video2.mp4'])
    ->export()
    ->inFormat(new X264)
    ->concatWithTranscoding($hasVideo = true, $hasAudio = true)
    ->save('concat.mp4');

I tested the concatenation without transcoding. No error, but it only outputs one video. it does not put the two videos side by side. When I try with transcoding, I get the error "Encoding failed"

[daviidy]

Sorry, the concatenation works. I wanted rather to stack two or more videos horizontally. Here is the code: $tab = ['video1.mp4', 'video2.mp4']; FFMpeg::fromDisk('local') ->open($tab) ->export() ->addFilter('[0:v][1:v]', 'hstack', '[v]') // $in, $parameters, $out ->addFormatOutputMapping(new X264, Media::make('local', 'stacked_video.mp4'), ['0:a', '[v]']) ->save(); But i get the error

Can you share the full log? https://flareapp.io/docs/ignition-for-laravel/sharing-errors

i changed the codec like that:

$tab = ['video1.mp4', 'video2.mp4'];
        FFMpeg::fromDisk('local')
        ->open($tab)
        ->export()
        ->addFilter('[0:v][1:v]', 'hstack', '[v]')  // $in, $parameters, $out
        ->addFormatOutputMapping(new X264('libmp3lame', 'libx264'), Media::make('local', 'stacked_video.mp4'), ['0:a', '[v]'])
        ->save();

But i get the same error. And in the debug there is a error message: Error while opening decoder for input stream #0:0 : Invalid argument

Stream mapping:
  Stream #0:0 (h264) -> hstack:input0 (graph 0)
  Stream #1:0 (h264) -> hstack:input1 (graph 0)
  Stream #0:1 -> #0:0 (aac (native) -> mp3 (libmp3lame))
  hstack (graph 0) -> Stream #0:1 (libx264)
Error while opening decoder for input stream #0:0 : Invalid argument

Hello, it works now. i just had to run php artisan config:clear and php artisan cache:clear

That's awesome, thanks for sharing!
