• FFMpeg crop a portrait (vertical) video square 1:1

  1er avril 2022, par hugger

  SOLVED... It was a UI issue... Not an FFpeg issue.

  


  I am new to FFMpeg. I am stuck on cropping a portrait video taken from a portrait device square.

  


  I would like my video output to be 1080x1080.

  


  First, I tried this.

  


  FFmpegKit.execute(`-y -i ${media.path} -vf "crop=1080:1080:exact=1" ${path}`)


  


  As I hoped, this worked for photos. (but strangely rotates the photo) - looking into that...

  


  BUT, for videos it does not work. instead it turns the video landscape.

  


  I then tried to add scale :

  


  FFmpegKit.execute(`-y -i ${media.path} -vf "crop=1080:1080:exact=1, scale=1080:1080" ${path}`)


  


  But this left me with the same result.

  


  Here are the console logs for some more information :

  ALMOST but not 1:1...

  


  I have not had any luck online trying to find a solution for this so I have decided to post on here.

  


  I hope I can get some guidance here !

• Format video to upload on instagram API (Nodejs)

  6 octobre 2022, par Rafael de Carvalho

  I'm trying to automate the process of posting photos and videos on instagram but I constantly get errors when uploading to instagram.

  


  I will leave a video duration error here but several others happen, I need to follow the following requirements :

  


  

  • Container : MOV or MP4 (MPEG-4 Part 14), no edit lists, atom moov in front of file

  


  • Audio codec : AAC, 48 kHz maximum sampling rate, 1 or 2 channel (mono or stereo)

  


  • Video codec : HEVC or H.264, progressive scan, closed GOP, 4:2:0 chroma subsampling

  


  • Frame rate : from 23 to 60 FPS

  


  • photo size :

    

    • Maximum columns (horizontal pixels) : 1,920

    


    • Minimum aspect ratio [columns/rows] : 4/5

    


    • Maximum aspect ratio [columns/rows] : 9/16

    


    


  


  • Video bitrate : 5Mbps maximum VBR

  


  • Audio bitrate : 128 kbps

  


  • Duration : maximum 60 seconds and minimum 3 seconds

  


  • File size : max 100 MB

  


  


  My code :

  


  import { S3 } from 'aws-sdk';
import { IgApiClient } from 'instagram-private-api';
import fs from 'fs';

const s3 = new S3();
const ig = new IgApiClient();
const bucket = 'posts';
const { INSTA_USER, INSTA_PASS } = process.env;

ig.state.generateDevice(INSTA_USER);

export const main = async () => {
  try {
    await ig.account.login(INSTA_USER, INSTA_PASS);

    const { Contents } = await s3.listObjectsV2({ Bucket: bucket, MaxKeys: 2, Prefix: 'memes/geral' }).promise();

    const files = await Promise.all(Contents.map(async ({ Key }) => {
      const file = await s3.getObject({
        Bucket: bucket,
        Key,
      }).promise();

      return file.Body;
    }));

    const publishResult = await ig.publish.video({
      video: files[0],
      coverImage: await fs.readFileAsync("../../src/assets/cover.png")
    });

    console.dir({ publishResult }, { depth: null })
  } catch (error) {
    console.error(error);
    throw error;
  }
}


  


  When I get a file from s3, it comes in the following format.
I'm taking the content of the body property and put it in the video property of the publish method.
Is it right ?
I also tried to save the file with fs.writeFile and dps use readFileSync like in the example but it also gave the same error.

  when I try to post a video under 60 seconds (apparently within the requirements) :

    "errorType": "IgConfigureVideoError",

        "    at main (C:\\Users\\User\\Desktop\\dev\\Insta\\.webpack\\service\\src\\functions\\webpack:\\src\\functions\\cronFreefireMemes.js:47:5)"
    ]
}


  


  I know that the error above is happening because of the size of the video which is longer than 60 seconds.

  


  But I would like to know if there is any way I can format any video to fit the instagram requirements.

  


  Any nodejs library ?

  


• Recording a webpage stream with multiple requests using PhantomJS & ffmpeg to /dev/stdout leads to ffmpeg error

  2 septembre 2016, par Allisson Ferreira

  First of all, sorry for my english.

  I’m in a quest for days. I’ve researched everywhere and I couldn’t find an answer to my problem.

  I’m using Nodejs, Phantomjs and ffmpeg in this scenary :

  • An user enters the site, login with facebook and he can ask for a video with his name and some random photos (gathered by /me/ & sent via JSON POST) ;
  • Node receive the user data, creates a child process (PhantomJS + ffmpeg) and awaits for a response to send the video URL to the user.

  When I run a single instance of this request, everything is working fine. BUT, when two or more users make the request, only one video is sent and the others process end up in a ffmpeg stream error.

  I think the reason is that all the ffmpeg processes are using the same place (/dev/stdout). Since one process is already using it, the others enters in a "can’t access" error. But it is a assumption, I don’t know how /dev/stdout really works.

  Here are my codes. (I have removed some lines and renamed some variables for better understanding, sorry for any mistake)

  index.js :

  var generateVideo = 'phantomjs phantom.js '+videoID+' '+userID+' | ffmpeg -vcodec png -f image2pipe -r 30 -i - -pix_fmt yuv420p public/videos/'+userID+'/'+videoID+'.mp4 -y';
  
  
  
  childProcess.exec(generateVideo, function(err, stdout, stderr) {
  
      var json    = {};
  
      json.video  = '/videos/'+userID+'/'+videoID+'.mp4';
  
      res.send(json);
  
  });

  phantom.js :

  var page            = require('webpage').create();
  
  page.viewportSize   = { width: 1366, height: 768 };
  
  page.settings.resourceTimeout = 10000;
  
  
  
  var args            = require('system').args;
  
  var videoID         = args[1];
  
  var userID          = args[2];
  
  
  
  page.open('http://localhost:3000/recordvideo/'+videoID, 'post', function(status){
  
      var frame       = 0;
  
      var target_fps  = 30;
  
      var maxframes   = page.evaluate(function () {
  
                          return getTotalDurationInSeconds();
  
                      }) * target_fps;
  
  
  
      setInterval(function(){
  
          page.render('/dev/stdout', { format: "png" });
  
          if( frame >= maxframes ){
  
              phantom.exit();
  
          }
  
          frame++;
  
      }, (1000 / target_fps));
  
  });

  And the error :

  [Error: Command failed: /bin/sh -c phantomjs phantom.js XXXXXXXX XXXXXXXX | ffmpeg -vcodec png -f image2pipe -r 30 -i - -pix_fmt yuv420p public/videos/XXXXXXXX/XXXXXXXX.mp4 -y
