• Anomalie #2773 (Nouveau) : Boucle recherche Forum : mauvaise selection avec le critère {tout}

  Le résultat d’une recherche dans les forums est différent selon que l’on emploie le critère plat ou le critère tout. Alors que le critère plat sélectionne correctement les messages contenant l’occurence recherchée, le critère tout sélectionne le premier message du thread et non la réponse à ce message (...)

• Has anyone used the speech driven animation and can you make it work ?

  16 août 2020, par hopw Jan

  I'm talking about this repo. I installed all the dependencies but I can't make it work. Any help is highly appreciated ( :

  


  I'm running python 3.7.5.

  


  This is my code :

  


  import sda
import scipy.io.wavfile as wav
from PIL import Image

va = sda.VideoAnimator(gpu=0, model_path="crema")# Instantiate the animator
fs, audio_clip = wav.read("example/audio.wav")
still_frame = Image.open("example/image.bmp")
vid, aud = va(frame, audio_clip, fs=fs)
va.save_video(vid, aud, "generated.mp4")


  


  Sadly it doesn't seem to work and it gives me this error :

  


  Warning (from warnings module):&#xA;  File "C:\Users\Alex\AppData\Local\Programs\Python\Python37\lib\site-packages\pydub\utils.py", line 170&#xA;    warn("Couldn&#x27;t find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)&#xA;RuntimeWarning: Couldn&#x27;t find ffmpeg or avconv - defaulting to ffmpeg, but may not work&#xA;Traceback (most recent call last):&#xA;  File "C:\Users\Alex\Desktop\test\test.py", line 8, in <module>&#xA;    vid, aud = va(frame, audio_clip, fs=fs)&#xA;NameError: name &#x27;frame&#x27; is not defined&#xA;</module>

  


  Spent about 2 hours and I can't do anything, I'm out of ideas.
If you take the time to help me thank you from the bottom of my heart.

  


• AWS Lambda for generate thumbnail save empty file

  30 octobre 2019, par Milousel

  I need to create aws lambda for creating thumbnail from video by using ffmpeg, which is saved on S3 and this thumbnail saved into S3 too.

  I downloaded ffmpeg from https://johnvansickle.com/ffmpeg/ page, set ffmpeg into nodejs file and send it into .zip. From this zip file I created ffmpeg layer. After that I connect my lambda with this ffmpeg layer. When I test it I receive Success response, but I save empty file (0 B size) into S3.

  const AWS = require("aws-sdk");
  
  const { spawn } = require("child_process");
  
  const { createReadStream, createWriteStream } = require("fs");
  
  
  
  const s3 = new AWS.S3();
  
  const ffmpegPath = "/opt/nodejs/ffmpeg";
  
  const allowedTypes = ["mov", "mpg", "mpeg", "mp4", "wmv", "avi", "webm"];
  
  const width = process.env.WIDTH;
  
  const height = process.env.HEIGHT;
  
  
  
  module.exports.handler = async (event, context) => {
  
    const srcKey = "test/0255f240-efef-11e9-862e-3949600f0ec9.mp4";
  
    const bucket = "video.devel.abc.com";
  
    const target = s3.getSignedUrl("getObject", {
  
      Bucket: bucket,
  
      Key: srcKey,
  
      Expires: 1000
  
    });
  
    let fileType = "mp4";
  
    console.log("srcKey: " + srcKey);
  
    console.log("bucket: " + bucket);
  
    console.log("target: " + target);
  
    if (!fileType) {
  
      throw new Error(`invalid file type found for key: ${srcKey}`);
  
    }
  
  
  
    if (allowedTypes.indexOf(fileType) === -1) {
  
      throw new Error(`filetype: ${fileType} is not an allowed type`);
  
    }
  
  
  
    function createImage(seek) {
  
      return new Promise((resolve, reject) => {
  
        let tmpFile = createWriteStream(`/tmp/screenshot.jpg`);
  
        const ffmpeg = spawn(ffmpegPath, [
  
          "-ss",
  
          seek,
  
          "-i",
  
          target,
  
          "-vf",
  
          `thumbnail,scale=${width}:${height}`,
  
          "-qscale:v",
  
          "2",
  
          "-frames:v",
  
          "1",
  
          "-f",
  
          "image2",
  
          "-c:v",
  
          "mjpeg",
  
          "pipe:1"
  
        ]);
  
  
  
        ffmpeg.stdout.pipe(tmpFile);
  
        ffmpeg.on("close", function(code) {
  
            console.log('code: ' + code);
  
          tmpFile.end();
  
          resolve();
  
        });
  
  
  
        ffmpeg.on("error", function(err) {
  
          console.log(err);
  
          reject();
  
        });
  
      });
  
    }
  
  
  
    function uploadToS3() {
  
      return new Promise((resolve, reject) => {
  
        let tmpFile = createReadStream(`/tmp/screenshot.jpg`);
  
        let dstKey = srcKey
  
          .replace(/\.\w+$/, `.jpg`)
  
          .replace("test/", "test/shots/");
  
        //const screensFile = "test/shots/";
  
        console.log("dstKey: " + dstKey);
  
        var params = {
  
          Bucket: bucket,
  
          Key: dstKey,
  
          Body: tmpFile,
  
          ContentType: `image/jpg`
  
        };
  
  
  
        s3.upload(params, function(err, data) {
  
          if (err) {
  
            console.log(err);
  
            reject();
  
          }
  
          console.log(`successful upload to ${bucket}/${dstKey}`);
  
          resolve();
  
        });
  
      });
  
    }
  
  
  
    await createImage(1);
  
    await uploadToS3();
  
    return console.log(`processed ${bucket}/${srcKey} successfully`);
  
  };

  When I test it I receive these logs :

• srcKey : test/0255f240-efef-11e9-862e-3949600f0ec9.mp4
• bucket : video.devel.abc.com
• INFO processed video.devel.abc.com successfully
• code : 1
• bucket : video.devel.abc.com
• dstKey : test/shots/0255f240-efef-11e9-862e-3949600f0ec9.jpg
• successful upload to video.devel.abc.com/test/shots/0255f240-efef-11e9-862e-3949600f0ec9.jpg
• processed video.devel.abc.com/test/0255f240-efef-11e9-862e-3949600f0ec9.mp4 successfully

So file is really created, but it is empty (size is 0 B), which is not ideal.
