Extension:PronunciationRecording/GSoC 2013/Project Updates

June
In the beginning of the month I was going through the documentation of Mediawiki codebase and the i18n framework. The beginning of the coding period was marked by installing the TimedMediaHandler locally and understanding its working. This was followed by a minor patch submission for "Including audio transcodes in TimedMediaHandler" : and studying how to write a handler for the WAV file format. Understanding about ID3 tags, RIFF container, WAV file format took some time as it was something new for me. During the course of writing the WAV Handler, we found out that the existing ID3 files were outdated and so I submitted a patch for updating the existing ID3 files. Our plan was to only allow PCM WAV to be uploaded, so for that I wrote a verifyUpload in the WAV Handler. Matthew's ingenious idea of using "wfDebugDieBacktrace" proved to be very helpful in testing the commit and finally it was merged. In the last week of June I started to work in the direction of "Implementing the Audio Recorder".

Mentor's Comments

 * In early June (during the Community Bonding Period), Rahul did a good job getting up to speed on MediaWiki and TimedMediaHandler, and continued planning for and designing the pronunciation recording flow. During the coding period, he successfully updated TimedMediaHandler to add WAV support.  There were some additional changes required, including updating the ID3 files, and only allowing PCM.  All of this was successfully completed by the end of June.  I believe he gained a better understanding of MediaWiki extension development in the process. Superm401 - Talk 18:09, 1 July 2013 (UTC)
