===================================
VDR Plugin 'span' Revision History
===================================

2007-05-03: Version 0.0.6
- Fixed visualization after pausing and starting playback again.
  Thanks to Morone for pointing out this one.

2007-03-23: Version 0.0.5
- Introduced a new setup parameter "Visualization delay (in ms)" to correct the
  gap when visualization is done way too early (e.g. when using softdevice).


2007-03-19: Version 0.0.4
- Changed the way PCM16-providers interact with SpAn (all providers must adapt
  the changes) - thx to Stefan Huelswitt for the suggestions and support.
  Only really visualized data is now being processed by the FFT, resulting
  in the positive side-effect that the CPU load of SpAn is slightly decreased.
  As to that change the define SPAN_SET_PCM_DATA_ID has now changed either to
  "Span-SetPcmData-v1.1"
- Updated the patches for mp3, cdda, graphlcd.
- Thanks to Morone there is no patch needed for his latest music-plugin = 
  "The Amazing Plugin Formerly Known As Mp3ng" (TAPFKAM).


2006-09-08: Version 0.0.3
- Bars falling completely now when pausing the replay
- Updated the patches for mp3ng*


2006-09-07: Version 0.0.2
- Implemented bar peaks (used in the graphlcd-patch and mp3ng).
- Therefore a change in the protocol "Span-GetBarHeights-v1.0" was neccessary, please
  adopt the changes. In this early stage the protocol version number is not increased.
- Slightly modified the management of clients and providers (for better performance).
- Modified the algorithm to calculate the bar heights and introduced some "default-
  optimizations" (for 16/20/32 bands) to make the spectrum look "more intuitive".
- Introduced the MainMenuAction that displays service-providers and their status.
- Introduced two new service protocols to be able to display service-providers and their
  status:
  "Span-ProviderCheck-v1.0" and "Span-ClientCheck-v1.0"
  All plugins (pcm-providers- and visualization-client-plugins) should implement
  them in order to inform the user about the capabilities of each plugin.
  Have a look at the README to get to know how to use them.
- Added patches to the "patches" folder:
  for mp3ng-0.9.13-MKIV-pre3-span.diff (enabling it to
  	provide pcm-data and to do the visualization)
  for lcdproc-0.0.10 (enabling it to do the visualization - tested only on 4x20 chars)
  for cdda-0.1.0 (enabling it to provide pcm-data to span)
  for graphlcd-0.1.3 (enabling it to do the visualization - tested only on 128*64px)
  for mp3ng-0.0.10-alpha (enabling it to display the peaks)


2006-08-30: Version 0.0.1
- Initial revision.
