  • 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 :

    


    enter image description here

    


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

    


    enter image description here

    


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

    


    enter image description here

    


    enter image description here

    


    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.

    


  • create mp4 slide show on raspbian

    25 novembre 2020, par Ramin

    I have RPi running raspbian.
I want a solution to convert a folder of image files to an mp4 slide show video that can be played with omxplayer.
I did it with ffmpeg and following command :

    


    ffmpeg -y -framerate .1 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p out.mp4


    


    It works with mpv media player but playing it with the flowing command with omx player does not do anything.

    


    omxplayer --loop --no-osd --win 0,0,128,224 --orientation 90 out.mp4


    


    I must use omx player to output on exact window and be compatible with older programs.
Not sure what would be the right way to do this. I have already a node js server running on Pi that I can use if needed.
Thanks
