• String is showing undefined

  30 octobre 2022, par Lol

  I am trying to create video using ffmpeg and returning its path to index.js but path is showing undefined.

  


  index.js

  


  app.get('/content/:myfact', async (req, res) => {
  let myfactdata = req.params.myfact;
  let myfact = myfactdata.replace("_", " ");
  const video = await generateVideo(myfact);
  console.log(video)
});


  


  This is my contentVideo.js

  


  const generateImage = require('./contentimage.js');
const { spawn } = require('child_process');

const generateVideo = async (myfact) => {
  await generateImage(myfact);
  const child = spawn('ffmpeg', [
    '-i', 'pictures/download/image.png', 'pictures/download/video.mp4'
  ]);
  child.on('close', function (code, signal) {
    const video = 'pictures/download/video.mp4'
    return video
  });
}

module.exports = generateVideo


  


• PyInstaller has strange interaction with YT_DLP

  12 janvier 2023, par MDorcelian

  this is for debugging - it's so I can get some test variables when im not passing a json as an argument.

  


  try: 
    data_string = sys.argv[1]

    # Convert the string back into an object
    data = json.loads(data_string)

    URL = data['url']
    PATH = data['filePath'] + "/"

except:
    URL = "https://www.youtube.com/watch?v=o9oGBnXqCgU"
    PATH = "C:/Users/PC/Downloads/videos"



  


  this is the weird part.

  


  try:
  ydl_opts = {
            'outtmpl':PATH_VIDEO + '/%(title)s.%(ext)s',
            'noplaylist':True,
            'format': "bv*[height<=1080][ext=mp4]+ba[ext=m4a]/b[height<=1080][ext=mp4] / bv*+ba/b",
            'mergeoutputformat':'mp4',
            'restrictfilenames':True,
            'ignoreerrors': False,
            'verbose':True,
            
        }
        with yt_dlp.YoutubeDL(ydl_opts) as ydl:
            ydl.download(URL)

            info = ydl.extract_info(URL, download=False)
            final_path_os = ydl.prepare_filename(info)
    except yt_dlp.utils.DownloadError as e:
        setJsonData(str(e))


  


  when i download videos as a script with code runner, it downloads normally completely fine. After I compile it as an exe and click it, it downloads completely fine.

  


  but when i pass my json through it, it knows where to download, it knows what's downloading, but it ALWAYS leaves two seperate video and audio files that were supposed to be combined. i assume its FFMPEG but i've included FFMPEG with the exe of pyinstaller.

  


  pyinstaller  --add-data "ffmpeg.exe;." --add-data "ffmpeg.exe;." -F returnMessage.py 


  


  and i've put ffmpeg in the same folder just in case

  


  setJsonData() writes to a json i have but i don't know how to debug because IT NEVER WRITES AN ERROR THERE. my exe just keepes running in the background. i've spent a day on this and am so lost.

  


  I've tried Exception error as e, nothing. I can't check the console because the application that launches this runs it silently.

  


  I'm sure it's the ydl.download(URL) that's the problem because I've set it up to make a test_json before it and it worked. if i put it after, it doesn't.

  


  I've checked the os paths to see if anything was up, but it's downloading in the correct place, just not downloading fully.

  


  i've downloaded the ffmpeg that was compatible with yt_dlp as well.

  


• From URL of Video GetThumbnail Using Nreco

  8 février 2016, par Muhammad Abid Fahad

  I working on a sharepoint project in which i have to upload the videos in the document library as videoset. after creating a video set i have have to upload the video and fetch the thumbnail from the video and upload it. video is uploaded succesfully using

  spfile = item.Folder.Files.Add(fuUpload.FileName, fuUpload.PostedFile.InputStream, true);

  I am using using Nreco to get thumbnail from the video. However my code works fine on local machine but its giving error "http://mysite/Download/abc/abc.mp4 : Server returned 401 Unauthorized (authorization failed) (exit code : 1)" when i am using my application from other pc browsers.

  ffMpeg.GetVideoThumbnail(videoPath, ms, 10) ; the error line.

  here is the code i am using

  private MemoryStream SaveThumbnail(string videoPath) 
  
      {
  
          MemoryStream ms; 
  
          try 
  
          {
  
              videoPath = "http://mysitehttp/Download/abc/abc.mp4"
  
              ms = new MemoryStream();
  
              SPSecurity.RunWithElevatedPrivileges(delegate() {
  
  
  
                  var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
  
                  ffMpeg.GetVideoThumbnail(videoPath, ms, 10); 
  
              });
  
  
  
  
  
          }
  
          catch(Exception ex)
  
          {
  
              throw ex;
  
          }
  
  
  
          return ms;
  
      }
