• PHP FFMPEG match Instagram aspect ratio requirements

  19 mai 2021, par Linesofcode

  As stated here, the Instagram API requirements to upload a video are :

  


  - Picture size
- - Maximum columns (horizontal pixels): 1920
- - Minimum aspect ratio [cols / rows]: 4 / 5
- - Maximum aspect ratio [cols / rows]: 16 / 9


  


  I'm having some problems figuring it out if the aspect ratio matches. I grab the width and height of the video like this :

  


  $ffprobe = \FFMpeg\FFProbe::create();
$video = $ffprobe->streams($file)->videos()->first();
$width = $video->get('width');
$height = $video->get('height');


  


  And then I know the ratio by dividing the width by height.

  


  The Instagram requirements about Portrait & Landscape videos are :

  


  Portrait - min: 0.8 ; max: 0.99
Landscape - min: 1.01 ; max: 1.78


  


  So why does a video of 848x480 (aspect ratio of 1.76) fails to upload to Instagram by returning "The video format is not supported" and how can I be completely sure that the aspect ratio matches the requirements before trying to upload ?

  


  Edit

  


  The full validation of Instagram requirements :

  


  $video = $ffprobe->streams($file)->videos()->first();
$audio = $ffprobe->streams($file)->audios()->first();
$codec = $video->get('codec_name');
$frameRate = eval('return ' . $video->get('avg_frame_rate') . ';'); // 30/1 -> 30
$width = $video->get('width');
$height = $video->get('height');
$duration = $video->get('duration');

$ratio = round($width / $height, 3);

// Portrait
if ($width < $height)
    if ($ratio < 0.8 || $ratio > 0.99)
        return false;
        
// Landscape
if ($width > $height)
    if ($ratio < 1.01 || $ratio > 1.78)
        return false;


if (!in_array($codec, ['h264', 'hevc']))
    return false;

if ($frameRate < 23 || $frameRate > 60)
    return false;

if ($width > 1920)
    return false;

if ($duration < 3 || $duration > 60)
    return false;

if ($audio)
{
    $aCodec = $audio->get('codec_name');

    if ($aCodec != 'aac')
        return false;
}

return true;

• FFMPEG Stream to Instagram Via instafeed.me OR YellowDuck

  3 mars 2024, par Jintor

  I'm trying to do video stream via RTMP to Instagram with FFMPEG

  


  I'm able to do it to facebook and twitter, but instagram is an other beast...

  


  when I create a live broadcast in rtmp.in or yellowduck I get a stream key

  


  when I do this

  


  ffmpeg -rtbufsize 256M -re -i file.webm -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 720x1280 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv rtmps://live-upload.instagram.com:443/rtmp/--key--here--


  


  ffmpeg outputs nothing, no error and I see no video in instafeed panel :(

  


  In other network I got sometimes error in ffmpeg log... but when it's to instagram : just blank nothing

  


  what do I miss ?

  


  here the log

• How to host a react.js ssr on vercel ?

  2 janvier 2024, par UltimateSheepConfusedAtCode

  I want to host a react.js server side rendering because of ffmpeg killing me with SharedArrayBuffer is not defined

  


  I've tried so many hosting service provider like firebase but now I want to host it to Vercel but I don't know how to make it works with react ssr. Can anyone help me ?

  


  When I run 'ssr' command in my machine it's work and ffmpeg is not throwing 'bad memory' or 'SharedArrayBuffer is not defined' but when I run it in vercel build command it stucks but the index.js/server.js is running I know because the main script is running and won't stop so the build is stuck but any solution ? I've search the problem but I guess nobody haven't asked this yet
