• Show portrait video to landscape on Videojs player as HLS ffmpeg Laravel

  11 décembre 2020, par TwistCode

  I am currently using the ffmpeg library through laravel sdk. For the landscape videos I have no problem with the scaling filters application, but with the portrait videos I need the video to look like the thumbnail below :

  


  

  


  But when I play the video, the player is distorted.

  


  

  


  Note : It should be noted that when I work with horizontal scales, the player looks good, but the video is distorted.

  


  

  


  

  


  this is my PHP Laravel code implementation

  


              FFMpeg::FromDisk('local')->open($this->media)
            ->exportForHLS()
            ->setSegmentLength(6) // optional
            /*
            ->addFormat($lowBitrate, function ($media) {
                $media->addFilter(function ($filters, $in, $out) {
                    $filters->custom($in, 'scale=854x480,setsar=1,setdar=16:9', $out); // $in, $parameters, $out

                });
            })*/
            // Portrait test
            ->addFormat($lowBitrate, function ($media) { 
                $media->addFilter(function ($filters, $in, $out) {
                    // $filters->custom($in, "scale='w=min(720,trunc((480*33/40*dar)/2+0.5)*2):h=min(480,trunc((704*40/33/dar)/2+0.5)*2)',pad='w=720:h=480:x=(ow-iw)/2:y=(oh-ih)/2',setsar='r=40/33'", $out); // $in, $parameters, $out
                    $filters->custom($in, "scale=239:-1", $out); // $in, $parameters, $out
                });
            })
            /*
            ->addFormat($midBitrate, function ($media) {
                $media->scale(1280, 720);
            })
            ->addFormat($highBitrate, function ($media) {
                $media->scale(1920, 1080);
            })*/
            ->save("public/hls/$video->id/$video->hash_name.m3u8");


  


  This is the command that runs at the server level for portrait videos.

  I don't really know if my problem is at the server or frontend level, but I would greatly appreciate any contribution.

  


• Using ffmpeg with libfdk-aac, encoding HE-AAC v1 and mono actually, but in decoding ffmpeg show HE-AAC v2 and stereo [closed]

  13 novembre 2024, par olojzyg

  ffmpeg encode command :

  


  


  ffmpeg -i aac_128000_f32le_22050_1.wav -c:a libfdk_aac -profile:a
aac_he -b:a 64k -channels 1 test.aac

  


  


  output :

  but decode this test.aac, I think HE-AAC and mono is corrent, but it show HE-AAC v2 and stereo, why ?
decode command :

  


  


  ffmpeg -i test.aac -f null -

  


  


  decode output :

  what happened ? test.aac is also displayed as 2 channels in Audition. But 1 channel is displayed in MediaInfo, and ADTS header is corrent :

  


  


  channel_configuration : 1 (0x1) - (3 bits)
