• failed to run ffmpeg player on android

  14 juin 2014, par Hogun

  I get source from AndroidFFmpeg.
  and I succeeded to build FFmpegLibrary project and FFmpegExample.
  When I installed a app on G2 phone, ran the app well.
  but when I installed it on Galaxy S3, the app is killed by failed ffmpeg-neon.so load.
  

  I have environments blow,

  • Ubuntu 12.04 LTS 64bit
  • Android NDK r9d
  • Android Toolchain 4.6
  • FFmpeg 2.2

• 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.

  


• Corrupt playback of .flv when using JW Player

  17 février 2019, par Artog

  This question is also asked on Audio-Video Production

  I have some files that when played in jwplayer the playback is corrupt.
  The files are encoded to h.264 using FFMpeg and there is other files encoded in the same way that works.

  At the moment we only use the flash version of the player.

  This problem started showing up after we did an upgrade to FFMpeg, so I haven’t ruled out that it could be an encoding error.

  the command used to run FFMpeg is :

  ffmpeg 
  
      -i /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.mov 
  
      -vcodec libx264 
  
      -preset ultrafast 
  
      -profile baseline 
  
      -acodec libfaac 
  
      -ab 96k 
  
      -crf 19 
  
      -vf movie="/home/adam/logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" 
  
      -y /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.flv

  I am in no way an expert in FFMpeg commandline, so feel free to point out any mistakes made.

  EDIT :

  A coworker was able to view a "corrupted" file. The only difference between my computer and his is that he have a Mac. Same flash version, same JW Player version. Something is not right here.
