• "FFmpeg : Error not transitioning to the next song in Discord Bot's queue."

  I have tried asking ChatGPT, Gemini, or Bing, and they always lead me into a loop of errors that cannot be resolved. This error only occurs when the song naturally finishes playing due to its duration. If the song is playing and I use the command !skip, the next song in the queue will play and function normally. I noticed that it seems like if a song ends naturally, the song queue is also cleared immediately. I hope someone can help me with this

  


• Inscriptions3 + Champs Extra

  6 août 2018

  Bonjour,

  Voici quelques points liées à l’utilisation de Champs Extra dans Inscription 3. Je vais détailler un peu mais dans l’idée, il s’agit d’adapter l’affichage de champs ou de leur valeur selon leur nature (input, radio, select ou fieldset), pour l’heure cela semble bien pensé pour les inputs et textarea, mais pour le reste ça pèche un peu.

  Page des utilisateurs (ecrire/ ?exec=inscription3_adherents) :

  Bug :
  Les champs fieldset et explication provoque une erreur alors qu’il devrait être ignorer. Il va de soit qu’on ne devrait pas cocher la colonne ’table’ pour ces champs dans la page de configuration, mais malheureusement c’est une erreur fréquente.

  Soucis d’affichage :

  1. Pour les selects, les entêtes des colonnes sont erronées, on voit par exemple ’label_nom_champs’ au lieu du nom du champs
  2. Pour les selects, on voit dans les cellules du tableau et non des valeurs
  3. Les dates sont au format SQL, pas si simple à lire pour les utilisateurs.

  Page de configuration (ecrire/ ?exec=configurer_inscription3) :

  Bug :

  • Dans la première colonne dans la partie des champs extras, le label est vide pour les checkbox, impossible de les identifier sinon par l’ordre dans la liste.
  • Idem avec les champs ’explication’
  • Il faut supprimer les cases à cocher de la colonne ’Table’ pour les champs ’explication’ et ’fieldset’, ils créés l’erreur fatales dans la page des utilisateurs.
  • Il faut supprimer les cases à cocher de la colonne ’Obligatoire’ pour les champs ’explication’ et ’fieldset’, car si ils sont cochés, le formulaire d’inscription ne pas être validé par l’utilisateur, c’est une erreur fréquente chez moi...

  Groupe de champs :

  Par le passé, j’ai voulu exploiter les fieldsets (Groupe de champs) de champs extra, pour grouper des champs...
  Malheureusement, cela ne semble pas être pris en charge par Inscription3.
  Les champs groupés disparaissent de la page de configuration, ils en deviennent inconfigurable...
  Et on perds les options d’affichage conditionnel par groupe par exemple...

  Vous pouvez compter sur moi pour des tests suite à la correction de ces bugs.

  Merci d’avance,

• How to flatten a VR video to display in normal screen ? [closed]

  14 mai 2023, par d-b

  I am not sure about the terminology here, but I have a VR-video that is intended to be shown using a headset with separate screens for each eye. It is not 3D in the sense that when you turn your head you will see something different, it is just "2,5D" so you get a sense of depth when looking at it. There are two video channels that are more or less identical, they are just recorded with slightly different angle, similar to how human eyes see the world. I hope this makes it clear what type of video I have, otherwise please ask for clarification in a comment (and if there is a special terminology for this type of video, please let me know).

  


  More details : the original video is 4320x2160, basically 2 square channels at 2160 x 2160.

  


  I want to show this video undistorted on a regular screen.

  


  I have read the following questions here on SO :

  


  


  1. How to reproject and join these two clips with ffmpeg ?

     


  


  2. Flatten 360 fisheye video

     


  


  3. How to de-warp 180 degree or 360 degree fisheye video with ffmpeg ?

     


  


  4. Flatten 360 fisheye video

     


  


  5. Unwarping 180 VR Footage with FFmpeg v360 Filter

     


  


  


  (and problably a few more).

  


  I think I want to extract the two video channels (note that they are in the same video stream, not like in a movie where you can have several separate audio streams for different languages) into separate files and then "undistort" them.

  


  (3) gave me a command to splitting the video into two files :

  


  ffmpeg -i -myclip.mp4 -filter_complex "[0]crop=iw/2:ih:0:0[left];[0]crop=iw/2:ih:ow:0[right]" -map "[left]" -map 0:a /tmp/left.mp4 -map "[right]" -map 0:a /tmp/right.mp4


  


  That seemed to have worked as expected but then I also need to "undistort" the content because it was filmed with some fisheye lens or something like that (straight lines not in the absolute centre of the image are more or less circular).

  


  (5) suggested this command :

  


  ffmpeg -i left.mp4 -vf "v360=input=hequirect:output=flat:h_fov=100:v_fov=67.5:w=1280:h=720" leftfixed.mp4


  


  but that produced an output that was 4320x2160 (obviously only from one channel, since input was just one channel) but just the centre of the original image, I estimate the content to be the 500x250 px (upscaled to 4320x2160, so very blocky) of the midpoint of the original image.

  


  How can I "undistort" this video so it looks good on a 2D-screen while the size is preserved ?
