  Im using NReco Videoconvertor on and asp.net web service but its failing with the error

  ****Error : Cannot convert media : Error opening filters !****

  When testing on my local development PC Windows 10 VS2017 it works fine. If I manually run ffmpeg as this too work fine

  Any thoughts please.

• MP3 files created using FFmpeg are not starting playback in browser immediately. Is there any major difference between FFmpeg and AVCONV ?

  23 janvier 2019, par AR5

  I am working on a website that streams music. We recently changed server from Debian (with avconv) to a Centos7 (with FFmpeg) server.
  The mp3 files created on Debian server start playback on browser (I have tested Chrome and Firefox) start almost at the same time they start loading into the browser (I used Network tab on Developer Tools to monitor this)

  Now after the switch to Centos/FFmpeg server, the files being created on this new server are displaying a strange behavior. They only start playback after about 1MB is loaded into the browser.

  I have used identical settings for converting original file into MP3 in both AVCONV and FFmpeg but the files created using FFmpeg are showing this issue. Is there something that might be causing such an issue ? Are there differences in terms of audio conversion between AVCONV and FFmpeg ?

  I have already tried

  I first found that the files created on old server (Debian/Avconv) were VBR (variable bitrate) and the ones created on new server were CBR (constant bitrate), so I tried switching to VBR but the issue still persisted.

  I checked the mp3 files using MediaInfo app and there seems to be no difference between the files.

  I also checked if both files were being served as 206 Partial Content and they both are indeed.

  I am trying to create mp3 files using FFmpeg that work exactly like the ones created before using avconv

  I am trying to make the streaming site work on the new server but the mp3 files created using FFmpeg are not playing back correctly as compared to the ones created on the old server. I am trying to figure out what I might be doing wrong ? or if there is a difference between avconv and FFmpeg that is causing this issue.

  I am really stuck on this issue, any help will be really appreciated.

  Edit

  I don’t have access to old server anymore so I couldn’t retrieve the log output of avconv. The command that I was using was as follows :

  avconv -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"

  Here is the command and log output from new server :

  ffmpeg -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"

• Anomalie #4276 : fonctions non définies dans porte_plume_pipelines.php

  24 janvier 2019, par François Palangié

  Bonjour,

  Vous avez raison c’est la version 1.18.3 que j’ai maintenant, 1.18.1
  devait être le numéro de version avant que je réinstalle la dernière
  version de SPIP.

  Le problème était le même avec la 18.1.1 et la 18.1.3 . Le problème est
  intervenu un matin sans que j’ai rien changé, je suppose que c’est mon
  hébergeur qui a changé l’environnement et que c’est la cause du
  problème... mais c’est curieux que cela produise ce type d’erreur !

  Cordialement,

  François
