• FFMpeg + OpenAL

  24 juillet 2013, par Dekowta

  I've been having a problem decoding different codecs into PCM 16 little-endian which is the supported format for OpenAL (I believe that is correct).

  I am using the windows pre-compiled libraries for FFMpeg (dont know if that effects anything).

  The code I have so far is here http://pastebin.com/T4wGL72a

  I have aiff and wav working (though with single channel OpenAL wants to have half the frequency and im not really sure why).

  The main problem is encoded audio files.

  mp3 files play sometimes (sometime get missing header) but end up stuttering with noise and are high pitched.

  ac3 files played the first preloaded buffers and then the frame would not have any more decoded data in the data array (did not check to see if the packet fetched encoded data or not).

  ogg files are the same as ac3

  m4a files would never finish the frame so I have no idea what happens when they do.

  wma files stutter and have a lot of noise but it is not high pitched like mp3 files

  I don't work with audio very often so its difficult for me to get my head round it and this is also the first time I've worked with FFMpeg.

  I'm sure there is something i'm doing very wrong I just need a hand on pointing out where it is.

  Thanks

  Chris.

  avisynth : corrected interlace detection
  AviSynth works on frame-based video by default, which can
  
  be either progressive or interlaced. Some filters can break
  
  frames into half-height fields, at which point it considers
  
  the clip to be field-based (avs_is_field_based can be used
  
  to check for this situation).
  To properly detect the field order of a typical video clip,
  
  the frame needs to have been weaved back together already,
  
  so avs_is_field_based should actually report 'false' when
  
  checked.

• Announcing Long Term Support in Piwik 2 – The analytics platform for your mission critical projects

  11 janvier 2016, par Matthieu Aubry — About, Development

  We are proud to announce our Long Term Support (LTS) for Piwik 2.X !

  Why Long Term Support (LTS) ?

  Part of our mission is to ready Piwik for the enterprise — and ready the enterprise for Piwik. Our fast release cycle and our ability to quickly innovate has served us well for the past seven years and has lead Piwik to being one of the most popular open source projects, used by over one million websites worldwide. But Piwik’s success today has also shown us that this fast release cycle is not suited for all users and customers. Like most large open source projects (such as Ubuntu, Firefox, Debian, Symfony, Node.js, etc.) at Piwik we now also offer a Long Term Support release which gives users the confidence that Piwik can be used for mission critical projects for months to come.

  What does LTS mean for Piwik ?

  For the duration of the LTS period, Piwik 2.X will continue to receive the following fixes :

  • Critical bugs causing data loss or data corruption.
  • Major and Critical security issues.

  Our goal is to offer you a Piwik LTS release that you can trust for all your mission critical projects.

  How long will Piwik 2.X be supported ?

  Piwik 2.X will be supported for at least 12 months after the initial release of Piwik 3.0.0.
  Piwik 3.0.0 is expected to be released in the second half of 2016.
  This means that Piwik 2.X will be supported at least until the second half of 2017.

  Which Piwik version is LTS ?

  The latest Piwik 2.16.X release is our Long Term Support version.

  How do I benefit from the LTS version ?

  To get the full benefits of Piwik LTS, please make sure you are using the latest LTS version. First, update to the latest Piwik 2.X version, then Configure Piwik to use the LTS release channel and then update to the latest LTS version.

  How do I configure Piwik to use the LTS version ?

  By default, Piwik will not use the LTS version. When you use the one-click update your Piwik instance will be updated to the very latest release : when Piwik 3.0.0 will be released, the one click update will update your instance to 3.0.0. It is however possible to configure your Piwik so that you will stay on Piwik 2.X and keep using the LTS Long Term Support version :

  • Login Piwik as the Super User,
  • Go to Settings > General > Update settings,
  • Under “Release channel” click “Latest stable 2.X Long Term Support version”, and click “Save”.
    

  How do I get professional Piwik Support ?

  If you need professional support for your Piwik service get in touch with the Piwik experts.
