• fluent-ffmpeg converting MKV to MP4 gives error "Conversion Failed"

  19 juillet 2019, par Jackie

  I am trying to use fluent-ffmpeg to stream a video from disk, this video is a MKV file. I am trying to transcode this video to MP4 on my NodeJS server and stream it to the client. However, I keep getting the error code 1: Conversion failed! when I try to transcode the MKV file to MP4. Does anyone know why I am getting this error ?

  My code works when I try to transcode a MP4 file to MKV (matroska), but it does not work the other way around.

  Here is the code I am using :

  app.get('/video123', function (req, res) {
  
    var path = 'assets/sample2.mkv';
  
    ffmpeg(path)
  
      .format('mp4')
  
      .on('end', function () {
  
        console.log('file has been converted successfully');
  
      })
  
      .on('progress', function (progress) {
  
        console.log('Processing: ' + progress.frames + 'frames done');
  
      })
  
      .on('error', function (err) {
  
        console.log('an error happened: ' + err.message);
  
      })
  
      .pipe(res, { end: true });
  
  });

  curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

• FFmpeg "HTTP 404 not Found" "Failed to open an initialization section in playlist 0" "Error when loading first fragment, playlist 0"

  6 août 2020, par jas_123

  For some reason FFmpeg cant play the video I want. Im making a Discord bot with youtube-dl. My FFmpeg options are FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}

  


  Is there anything I need to change in my options ? Also, this only happens when youtube-dl says Downloading MPD manifest. Everything else works until that shows up.
