• laravel ffmpeg setAdditionalParameters not adding filters when using exportForHLS

  24 juin 2021, par Warren Visser

  I am trying to add additional filters using the setAdditionalParameters method to the bitrate using Laravel Ffmpeg. When I add the additional filters it does not show when used in combination with exportForHLS. It does however work when using the export method.
When using exportForHLS the addFilter method adds a complex filter and not a simple filter. Any idea how to achieve this or is this a bug inside the package.

  


    public function convert(File $file, Movie $movie)
{
    try {
        $additionalParameters = ['-preset:v', 'ultrafast'];

        //  convert video to multiple bitrates
        $higBitrateFormat = (new X264('copy'))
            ->setAudioChannels(2)
            ->setKiloBitrate(3000)
            ->setAdditionalParameters($additionalParameters);

        $mediaOpener = FFMpeg::fromDisk($file->disk)
            ->open($file->path)
            ->exportForHLS()
            ->setSegmentLength(4)
            ->setKeyFrameInterval(48)
            ->addFormat($higBitrateFormat)
            ->toDisk('streamable_videos')
            ->save($file->uuid . '.m3u8');

        $attr = ['converted_at' => Carbon::now()->toDateTimeString()];
        $this->movieRepositoryInterface->update($movie->id, $attr);
        return $mediaOpener;
    } catch (EncodingException $exception) {
        $attr = ['conversion_failed' => 1];
        $this->movieRepositoryInterface->update($movie->id, $attr);
        Log::error('encoding failed.', [$exception->getErrorOutput()]);
        throw new CustomEncodingException($exception->getMessage(), $exception->getCode());
    }
}


  


  Here is the ffmpeg output :

• Intel QuickSync error : Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  30 novembre 2018, par Arie Syamsudin

  I want to make IPTV with a topology like this :

  Restream / source -----> IPTV server -----> User

  The problem at the moment is the question of bandwidth that is still large.

  Finally I announced by IPTV software providers to transcode with Intel QuickSync video and FFmpeg.

  I followed the steps given by the software provider at the following link :
  http://www.ezhometech.com/document/intel_ffmpeg.txt

  Which comes from the link below :
  https://www.intel.com/content/dam/www/public/us/en/documents/white-paper...

  I installed IPTV software on a laptop with an Intel processor, chipset and VGA.

  but when I do a transcoding test, an error always appears :
