• ffmpeg and 64 bit architecure

  16 avril 2015, par nevgauker

  there is a pretty old project i need to upload to the store.
  how old you ask ? 32 bit only ,no arc and no story board...

  since in this days in mandatory to make a single archive that support 32 and 64 build ...i decided to update the valid architecture of the project.
  i discovered that many frameworks do not support 64 bit and i have to update them . the most problematic is ffmpge..
  here i few things that i tried to do and fail :

  1. add ffmpeg as a static libary
  2. add ffmpeg using cocoa pods

  nothing helps...

  here are some of the errors i get :
  Undefined symbols for architecture arm64 :
  "_av_read_frame", referenced from :
  -[Demuxer readPacket :] in Demuxer.o
  "_av_malloc", referenced from :
  -[Streamer writePacket :] in Streamer.o
  "_av_register_all", referenced from :
  +[Streamer initialize] in Streamer.o
  "_avformat_write_header", referenced from :
  -[Streamer writePacket :] in Streamer.o
  "_avio_close", referenced from :
  -[Streamer dealloc] in Streamer.o
  "_av_new_stream", referenced from :
  -[Streamer writePacket :] in Streamer.o
  "_avformat_free_context", referenced from :
  -[Streamer dealloc] in Streamer.o

  any suggestion ?

  the only way i succeed is turn on the "build active architecture only" (and of course get rejected when i try to upload to the store)

  if you refer me to any shell script, please instruct me how to use it

  thanks

• 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 !
