• How to set "channel_layout" or "ch_layout" in 6.1 FFMPEG [closed]

  5 janvier 2024, par Steven porite

  In avcodec_open2(), it will set the "avctx->ch_layout.order = AV_CHANNEL_ORDER_UNSPEC ;" when
avctx->channel_layout is false. If I want to set the ".order = AV_CHANNEL_ORDER_NATIVE",
what can I do ?

  


  

  


  I don't know how to use the option to set "channel_layout" or "ch_layout" ? Hope someone can help me.

  


• Piwik Developer Guides : helping you make the most of the Piwik platform

  16 avril 2015, par Piwik Core Team — Community, Development, Plugins

  At Piwik we are creating the leading open analytics platform that gives every user full control over their data. Today we are excited to announce the official launch of the Piwik Developer Guides at developer.piwik.org. The Developer Guides complement existing User Guides and more than 250 FAQs.

  Piwik Developer Guides

  The Developer guides will help you whenever you need to :

  • Integrate Piwik analytics in your website or application — Integration guides explain (1) how to track users of your apps (with JavaScript Tracking or other Tracking API Clients) and (2) how to query Piwik’s reporting data to integrate it into your application (Accessing Piwik data).
  • Develop a new Plugin for Piwik — Plugin development guides introduce the Piwik Platform and explain how to get started with creating a new plugin to extend and customise Piwik.
  • Piwik API references — API References include the references for Tracking API, Analytics API, JavaScript Tracking API and the Database schema.
  • See what’s changed in the platform — Changelog for Piwik platform developers lists all changes to our HTTP API’s, Plugins, Themes, etc.

  Helping Developers innovate with Piwik

  Piwik is an open platform – it is open because users control their data, users control the Piwik software (it is Free/libre software) and also because users can extend the platform via the powerful plugins architecture. Piwik users can already choose from 49 plugins available on the Marketplace ! (as of 2015 April 16th)

  Now that developer guides are officially released, we are hopeful that even more talented developers will be able to create Plugins and distribute them on the Marketplace.

  Share your feedback

  We are committed to providing excellent Developer Guides and to achieve this, we need to hear your feedback and suggestions. To send us a message, click on the “Give Feedback” link in the footer of pages (we are listening !).

  What’s coming next ?

  • Platform Developer Changelog will continue to list all changes to the Piwik Platform and APIs.
  • We will regularly update the guides when there are changes in the platform.
  • We will improve existing guides based on users’ feedback and suggestions (tasks are tracked in this issue tracker on Github.)

  We hope you find the guides useful, and thank you for being part of the Piwik community !

  

• How do you compile Winff ?

  3 mai 2015, par Richard

  I downloaded the WinFF source code in the hopes the new version would solve a segfault.

  It’s sitting, extracted, in its folder. But I see no ./configure, nothing make would know what to do with, no binaries, and no compilation instructions :

  $ ls
  
  AUTHORS        COPYING           README-Presets.txt  unit2.lfm  unit4.pas  winff.1      winff.rc
  
  changelog.txt  docs              README.txt          unit2.pas  unit5.lfm  winff.ico
  
  clean.bat      languages         RESOURCES.RC        unit3.lfm  unit5.pas  winff-icons
  
  clean.sh       potranslator.pas  unit1.lfm           unit3.pas  unit6.lfm  winff.lpi
  
  COMPILE.TXT    presets.xml       unit1.pas           unit4.lfm  unit6.pas  winff.lpr

  Does anyone know how I can try to actually compile the code ?

  All we get is a README.txt :
