• Python FileNotFoundError : [Errno 2] No such file or directory : 'ffprobe' on Synology

  24 juillet 2022, par Junn Sorran

  I was making a small python 3.8 script to sort photos and videos according to their metadata on my Synology NAS (working on DSM 7.0), overall it works well on ubuntu but it fails on the NAS with this error :

  


  


  FileNotFoundError : [Errno 2] No such file or directory : 'ffprobe'

  


  


  I've been searching everywhere for help on this issue, I saw this post and tried the solutions but I still got the error on any video I try to read metadata from.

  


  ffmpeg is installed and so are ffmpeg-python and ffprobe-python

  


  Here's my test code :

  


  from datetime import datetime
import ffmpeg

name = "VID_20200130_185053.mp4"
path = "/volume1/photo/phone/DCIM/Camera/"
data_keys = ["DateTimeOriginal", "DateTime", "creation_time"]
file = f"{path}{name}"
print(file)
vid = ffmpeg.probe(file)['streams']
# vid = ffprobe.FFProbe(file).streams
for key in data_keys:
    if key in vid[0]['tags']:
        print(datetime.strptime(vid[0]['tags'].get(key).split('T')[0], "%Y-%m-%d"))


  


• 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.

  Error :

}


  


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

  


  {
    "errorMessage": "POST /api/v1/media/configure/?video=1 - 403 Forbidden; ",
    "errorType": "IgConfigureVideoError",
    "stackTrace": [

        "    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 ?

  


• Crop and pinch zoom image with FFMPEG

  27 septembre 2022, par hugger

  I am working on a simple photo editor component for a mobile app which requires the user to be able to pan and scale (zoom) an image to be cropped. S/O to @kesh for the help so far !

  


  With the pinch zoom value which ranges from 1-5, I wish to use this in my FFMPEG execution along with the crop command :

  


    cropSelected() {
    this.setState({ isCropping: true });

    const diff =
      this.props.videoHeight / (this.state.aspectRatio * deviceWidth);
    const offsetDiff = this.state.offsetTopTranslate * diff;

    var filterPathPostCrop =
      this.props.type === 'photo'
        ? RNFS.DocumentDirectoryPath + '/afterCrop.png'
        : this.props.type === 'gif'
        ? RNFS.DocumentDirectoryPath + '/afterCrop.gif'
        : RNFS.DocumentDirectoryPath + '/afterCrop.mp4';
    //hardcoded zoom at 1.2x for example!
    FFmpegKit.execute(
      `-y -i ${this.state.mediaSource} -vf "crop=iw/1.2:ih/1.2:0:${offsetDiff},scale=iw:-1" -qscale 0 -frames:v 1 ${filterPathPostCrop}`
    ).then(async (session) => {
      const returnCode = await session.getReturnCode();
      if (ReturnCode.isSuccess(returnCode)) {
        // SUCCESS

        Animated.spring(this._pinchScale, {
          toValue: 1,
          useNativeDriver: true,
        }).start();

        this.setState(
          {
            mediaSource: filterPathPostCrop,
            videoSourcePreview: `${filterPathPostCrop}?${new Date().getTime()}`,
            ffMPEGinProgress: null,
            aspectRatio: 1080 / 1080,
            videoTime: 0,
            isPlayingVideo: false,
            isCropping: false,
            filterOutputIsAlt: !this.state.filterOutputIsAlt,
            wasCropped: true,
          });
      } else if (ReturnCode.isCancel(returnCode)) {
        // CANCEL
      } else {
        // ERROR
        alert('error');
      }
    });
  }


  


  I drew this to illustrate what I am trying to achieve here.

  


  

  


  I hope this helps !
