• Issue with video compression using HLS from laravel protonemedia/laravel-ffmpeg package

  29 mars 2023, par Mateo Kantoci

  I'm using laravel-ffmpeg package in order to compress videos and save it as .m3u8.
In another words, I have a job that is gathering all uncompressed files and compress them 1by1 and save them to google cloud storage. Furthermore, compression is using exportForHLS from package and throws an error :

  


  ProtoneMedia\LaravelFFMpeg\Exporters\HLSPlaylistGenerator::getStreamInfoLine(): Return value must be of type string, null returned in /var/www/html/ipaparazzo/vendor/pbmedia/laravel-ffmpeg/src/Exporters/HLSPlaylistGenerator.php:32


  


  In some cases compression works but my job is failing for most of the time.

  


  Anyone experienced similar issue ?

  


  P.S. It is working as expected when using public storage.

  


  This is my code exactly as per laravel-ffmpeg documentation :

  


  ->exportForHLS()
->setSegmentLength(10) // optional
->setKeyFrameInterval(48) // optional
->addFormat($lowBitrate, function($media) {
    $media->scale(426, 240);
})
->addFormat($midBitrate, function($media) {
    $media->scale(640, 360);
})
->addFormat($highBitrate, function($media) {
    $media->scale(640, 480);
})
->onProgress(function ($percentage) {
   echo "{$percentage}% transcoded\n";
})
->toDisk('gcs2')
->save($videoPath)
->cleanupTemporaryFiles();


  


• How to get height and width of a video downloaded from a URL in PHP ?

  28 septembre 2016, par Parthapratim Neog

  I am using file_get_contents() function to download an mp4 video from a given link(for example https://media.giphy.com/media/haB6FriHgXPuE/giphy.mp4). I want to get the Height and width of the downloaded video file using PHP. file_get_contents() gives me the binary data of the video, and I want to extract the height and width from this data.

  Is there any way to do that, without using ffmpeg in PHP ?

• How to streaming audio with ffmpeg and container of my own choosing ? [closed]

  2 octobre 2024, par xchg.ca

  I'm streaming an ac3 audio via rtsp using ffmpeg like this :

  


  > ffmpeg -re -f ac3 -i sample4.ac3 -ar 8000 -f mulaw -f rtsp rtsp://10.22.22.11:8554/audiostream


  


  In the RTSP protocol exchange it DESCRIBEd like this :

  


  > Session Description Protocol
>     Session Description Protocol Version (v): 0
>     Owner/Creator, Session Id (o): - 0 0 IN IP4 127.0.0.1
>     Session Name (s): No Name
>     Connection Information (c): IN IP4 0.0.0.0
>     Time Description, active time (t): 0 0
>     Media Description, name and address (m): audio 0 RTP/AVP 96
>     Media Attribute (a): control:rtsp://10.22.22.11:8554/audiostream/trackID=0
>     Media Attribute (a): rtpmap:96 mpeg4-generic/8000/2
>     Media Attribute (a): fmtp:96 config=1590; indexdeltalength=3; indexlength=3; mode=AAC-hbr; profile-level-id=1; sizelength=13;
> streamtype=5


  


  I wondering if I can specify specific container in ffmpeg command line while keeping media format the same. For example I want MPEG-TS container instead of mpeg4. Looking through the ffmpeg docs did not really helped me.
