  • Dynamic control of debug output
  • Ability to limit graphics resource usage
  • Add 'install' mechanism

• API changes
  • Version header 'mheg5_version.h' is generated when library is build. This must be used when calling MHEG5_Open().
  • DVB_MhegPrefSubtitleLangs() may be used other than for South Africa profile

  • To limit graphics resource usage, provide MHEG5_SetSurfaceThreshold()
  • DVB_MhegICStreamingSetup() has two extra parameters to specify required Audio and Video codecs
  • When supporting Connected TV, added calls to DVB_MhegApplicationLaunch() and DVB_MhegGetMimeTypeSupport()
  • Remove call to DVB_MhegIsKeySupported(), and replace with provided functions: MHEG5_KeySupportDisabled() and MHEG5_KeySupportEnabled(). Default is assumed all keys are supported by platform.
  • Added calls to DVB_MhegEventsStart() and DVB_MhegEventsStop() to start/stop listening to DVB events
  • Replace all STB_VT… function calls by the DVB_Mheg… equivalent.
