• Anomalie #4787 (Nouveau) : Le selecteur d’article ne marche plus.

  20 mai 2021, par Maïeul Rouquette

  Soit un page du privé

  prive/squelettes/contenu/titi.html, appelé via ecrire/?exec=titi.

  En spip 3.2
  

  selecteur/articles,name=toto,rubriques=1,articles=1}/>

  
  permet de selection un article.

  pas en spip 4 (et donc ce n’est pas lié à saisies !)

  J’ai du mal à comprendre exactement le picker, mais en 3.2 pour les rubriques racine j’ai

  <li class="rubrique"> <a href="#"><img class="add" src="http://core.spip.org/projects/prive/themes/spip/images/ajouter-16.png" alt="ajouter" width='16' height='16' /></a>AH
   <a class="ajax bind-ajax" href="http://core.spip.org/projects/spip/?exec=titi&#38;picker=1&#38;id_r=1"><img src="http://core.spip.org/projects/prive/themes/spip/images/fleche-droite-16.png" alt="" class="ouvrir" width='16' height='16' /></a></li>

  alors qu’en 4.0 (commit 604e76ddf) j’ai
  

  <li class="rubrique"> <a href="#"><img class="add" src="http://core.spip.org/projects/prive/themes/spip/images/ajouter-xx.svg?16px" alt="ajouter" width='16' height='16' /></a>blop</li>

  
  il manque le second a en bidn-ajax
  j’ai pas investigué plus que cela, car c’est un domaine obscure pour moi.

• ffplay - route incoming audio stream to specific channels / convert channel layout

  7 septembre 2022, par miasma

  i need to play a mp3 stream (stereo) via ffplay and send it to specific output channels on my multichannel audio hardware.

  


  stream (stereo) -> output 3 & 4
while doing that the unused channels should stay silent, as i want to send to them from other instances of ffplay.

  


  how would i go about to do that ?

  


  i already tried a lot of different approaches without luck, mostly based on this :

  


  ffplay -i http://blablabla -af 'channelmap=map=0-2|1-3' -nodisp


  


  as well as

  


  ffplay -i http://blablabla -af 'channelmap=map=0-2|1-3=channel_layout=6.0'


  


  thank you for any help, i'm slowly going crazy digging through the manuals and trying out variations of the same command for hours …
😵‍💫

  


  ps : i'm running ffplay 5.1.1 on mac os 12.5.1 on m1max

  


• Getting ffmpeg to work on a nodejs server : Error : ffmpeg exited with code 1 : Output #0, wav, to 'output.wav'

  14 mai 2023, par Djaenike

  I need to convert an m4a buffer stream to a wav buffer stream. I'm trying to accomplish this through ffmpeg-static and fluent-ffmpeg on a nodejs backend. I'm using multer to process the buffer stream coming from the client, then pass it through a convertM4AToWAV, which

  


  Here is the code I'm using to establish ffmpeg and convert the buffer stream.

  


  const ffmpeg = require('fluent-ffmpeg');
const ffmpegStatic = require('ffmpeg-static');
ffmpeg.setFfmpegPath(ffmpegStatic);

...more code here for the api route...

const convertM4AToWAV = async (m4aBuffer) => {
  console.log(`buffer in: ${m4aBuffer}`);
  try {
    const wavBuffer = await ffmpeg(m4aBuffer)
      .toFormat('wav')
      .on('start', (command) => console.log('FFmpeg command:', command))
      .on('end', () => {
        console.log('Conversion complete.');
      })
      .save('output.wav');
    return wavBuffer;
  } catch (error) {
    console.error('Error converting audio buffer stream to wav:', error);
    throw error;
  }
};


  


  And here is the error message I'm seeing :

  


  //I can see the buffer come in
buffer in: ↑ftyp3gp4isom3gp4☺mdat????????.....
//I can see the command
FFmpeg command: ffmpeg -y -f wav output.wav
//Error message thrown
Error transcribing audio: Error: 13 INTERNAL: Request message serialization failure: invalid encoding
    at callErrorFromStatus
...file directory jibberish...
code: 13,
  details: 'Request message serialization failure: invalid encoding',
  metadata: Metadata { internalRepr: Map(0) {}, options: {} },
  note: 'Exception occurred in retry method that was not classified as transient'
}
error - uncaughtException: Error: ffmpeg exited with code 1: Output #0, wav, to 'output.wav':
Output file #0 does not contain any stream


  


  Any thoughts why this error is thrown ? My gut is telling me it's because I haven't configured ffmpeg correctly on the server.
