• Trouble with Cross-Origin Headers : Stripe and ffmpeg Integration in Next.js

  7 février 2024, par Duke

  I'm using this excellent template from vercel as a base for my project :

  


  https://vercel.com/templates/next.js/subscription-starter


  


  I've used it for many projects and the Stripe integration works flawlessly. However for a new project I needed to incorporate ffmpeg which relies on SharedArrayBuffer :

  


  https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer


  


  So I need to set the appropriate HTTP response header which i've set in my next.config.js file as below :

  


        {
        source: '/(.*)',
        headers: [
          {
            key: 'Cross-Origin-Embedder-Policy',
            value: 'credentialless'
            // value: 'require-corp'
          },
          {
            key: 'Cross-Origin-Opener-Policy',
            value: 'same-origin-allow-popups'
          }
        ]
      }


  


  Now the issue is that settings these breaks Stripe. It blocks the request :

  


  https://js.stripe.com/v3/m-outer-3437aaddcdf6922d623e172c2d6f9278.html


  


  Which appearently loads more resources that are needed for the checkout session to function. The customer portal works but checkout doesn't. I've literally tired every possible permutation of headers with different values but in all cases either Stripe works but ffmepg doesn't (cause SharedArrayBuffer doesn't work) or vice versa. It's been a week and I've tired everything and can't find anything online that works. Not even ChatGPT can help which ironcelly asks me to contact Stripe customer support. I would highly appreciate if anyone could even point me in the right direction. I Thank you in advance good Sir/Maam.

  


  Note that Checkout works fine with just :

  


  key: 'Cross-Origin-Opener-Policy',
value: 'same-origin'


  


  Just Cross-Origin-Embedder-Policy breaks it

  


• Anomalie #3185 (Nouveau) : Problème avec les hooks de SVN sur la zone

  13 mars 2014, par Sylvain Lesage

  Salut,

  j’ai foiré un commit (http://zone.spip.org/trac/spip-zone/changeset/81171/_plugins_/tickets/trunk), j’ai envoyé sans message.

  Pour récupérer le coup, j’ai tenté de faire :

      svn propedit -r 81171 —revprop svn:log
  

  et de rentrer le message, mais je reçois

      svn : Revprop change blocked by pre-revprop-change hook (exit code 1) with output :
      /var/svn-repos/spip-zone/hooks/pre-revprop-change : 108 : /svnlook : not found
      /var/svn-repos/spip-zone/hooks/pre-revprop-change : 109 : /svnlook : not found
      /var/svn-repos/spip-zone/hooks/pre-revprop-change : 110 : cannot open 0 : No such file
      /var/svn-repos/spip-zone/hooks/pre-revprop-change : 110 : diffSec : not found
      Changing svn:log can only be performed by the original submitter 3 hours from commit.
      Please contact the administrator for further assistance.
  

  J’aurais donc le droit de changer mon message durant les 3 heures qui suivent le commit, mais ça ne marche pas. Est-il possible de régler le problème ?

  Pour info, le message du commit est :

  tickets - config des objets qu’on peut lier aux tickets.
  Et fonction d’autorisation pour "associertickets".
  
  Par défaut, aucun type d’objet ne peut être lié aux tickets
  
  (tous desactivés). A noter : a priori, on n’interdit pas
  
  de lier des tickets à d’autres tickets.

  26 février 2016, par combo_ci

  I try to transcode UDP stream to HLS (m3u8) file and put that file in a web server such as apache with this code :

  ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8 

  At first of trascoding progress i see a error

  [h264 @ 0x14c1c60] number of reference frames (0+4) exceeds max (3; probably corrupt input), discarding one

  But m3u8 file created successfully and i can play it in client. but after 2 or 3 minute i see some error

  [h264 @ 0x158d600] error while decoding MB 30 34, bytestream -10 dup=101 drop=0 [mpegts @ 0x149c660] PES packet size mismatch
