How to solve issue with ffmpeg being stuck at 'Opening an input file'
20 mai 2021, par zv989I am using a capture card to capture HDMI audio from another machine.



On my host, output of
arecord -lis as follow :


**** List of CAPTURE Hardware Devices ****
Home directory not accessible: Permission denied
card 0: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 1: capture [ezcap U3 capture], device 0: USB Audio [USB Audio]
 Subdevices: 1/1

The command that I use is :



sudo ffmpeg -f alsa -i hw:CARD=capture,DEV=0 -t 30 test.wav -loglevel debug



When I ran the command, the log seems to freeze at 'Opening an input file' as below :

How can I fix video processing and 500 Error - (Laravel, FFmpeg)
19 juillet 2019, par San Martín Figueroa PabloI’m setting up a new website with Laravel for uploading videos...
I have read all the possible solutions but none of them help me to solve the issue...This is my issue : When I upload a small file (<10mb) the web works fine, the video get uploaded and the video get converted, the dashboard shows the converted videos---
When I try to upload a large file, the file get uploaded, the video get converted with a green frame on it (really uggly) and the site goes to a 500 server error...
I’m using Laravel Jobs to do the conversion.
My Controller code :
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Storage;
use Symfony\Component\HttpFoundation\Response;
use Carbon;
use Closure;
use App\Jobs\ConvertVideoForPreview;
use FFMpeg\FFProbe;
use FFMpeg\Coordinate\Dimension;
use FFMpeg\Format\Video\X264;
use Pawlox\VideoThumbnail\Facade\VideoThumbnail;
use Pbmedia\LaravelFFMpeg\FFMpegFacade as FFMpeg;
use Illuminate\Contracts\Filesystem\Filesystem;
use App\Video;
class VideoController extends Controller
{
public function createVideo(){
return view('video.createVideo');
}
public function saveVideo(Request $request){
set_time_limit(0);
ini_set('memory_limit', '1024M');
//Validar Formulario
$validatedData = $this -> validate($request, [
'title' => 'required',
'description' => 'required',
'palabras' => 'required',
'video' => 'mimetypes:video/mp4,video/quicktime'
]);
$video = new Video();
$user = \Auth::user();
$video -> user_id = $user->id;
$video -> title = $request -> input('title');
$video -> description = $request -> input('description');
$video -> palabras = $request -> input('palabras');
$video_file = $request -> file('video');
if($video_file){
$video_path = 'original'.'_'.$video_file ->
getClientOriginalName();
Storage::disk('videos')-> put($video_path,
\File::get($video_file));
$videoUrl = storage_path('app/videos/').$video_path;
$storageUrl = storage_path('app/thumbs/');
$fileName = 'thumb'.'_'.time().'.jpg';
$second = 2;
VideoThumbnail::createThumbnail($videoUrl, $storageUrl,
$fileName, $second, $width = 640, $height = 480);
$video -> preview = $fileName;
$video -> video_path = $video_path;
}
$video -> save();
ConvertVideoForPreview::dispatch($video);
return redirect() -> route('home')
-> with (array(
'message' => 'El video se ha enviado con exito'));
}
public function getImage($filename){
$file = Storage::disk('thumbs') -> get($filename);
return new Response($file, 200);
}
public function getVideo($filename){
$file = Storage::disk('converted_videos') ->
get($filename);
return new Response($file, 200);
}
}This is my ConvertVideo Job :
<?php
namespace App\Jobs;
use App\Video;
use Carbon\Carbon;
use FFMpeg;
use FFMpeg\Format\Video\X264;
use Illuminate\Http\Request;
use Illuminate\Bus\Queueable;

class ConvertVideoForPreview implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable,
SerializesModels;
public $video;
public function __construct(Video $video)
{
$this -> video = $video;
}
public function handle()
{
$converted_name= 'preview'.'-'.$this -> video ->
video_path.'.mp4';
FFMpeg::open('videos/'.$this -> video -> video_path)
-> export()
-> inFormat(new \FFMpeg\Format\Video\X264)
-> save('converted_videos/'.$converted_name);
$this -> video -> update([
'video_preview' => $converted_name,
'processed' => true
]);
}
}One of my goals is to upload large video files (<=4GB), show a uploading process bar and a encoding process bar during the video upload.
I getting this error :

(Probably I’m missing one)...
Changed timeouts too.

Can anyone help me to reach this ?...
