/* ChangeLog added 2002-01-10
 * 2003-11-28:
 *  Added a patch from Anders Rune Jensen to support the latest em8300 CVS
 *  changes.
 *
 * 2003-02-19:
 *  Yet another patch from Tamas Kohegyi to fix subpic placement.
 *
 * 2003-01-12:
 *  Added patch from Tamas Kohegyi to fix subpic placement with freetype.
 *
 * 2003-01-02:
 *  Added patch from Jens Axboe that makes vo_dxr3 return to previous TV norm
 *   after quiting.
 *  Added patch from Thomas Jarosch that fixed a lot of textual ouput
 *   errors.
 *
 * 2002-12-24: (Hohoho)
 *  Added patch from Thomas Jarosch <[e-mail]> which adds support
 *   for setting the TV norm by movie framerate.
 *
 * 2002-11-03:
 *  Cleaned up syncing code and renamed setup variables so
 *   they can be accessed from the GUI.
 *
 * 2002-11-02:
 *  Added native overlay support, activate with :overlay
 *   you have to run dxr3view to modify settings (or manually
 *   edit the files in ~/.overlay.
 *
 * 2002-10-29:
 *  Added new sync-engine, activate with :sync option.
 *  Greatly improved commandline parser.
 *  Replaced :noprebuf with :prebuf and made noprebuf the default.
 *
 * 2002-10-28:
 *  Fixed multicard bug on athlons
 *
 * 2002-07-18:
 *  Disabled spuenc support, this is still not stable enough =(
 *
 * 2002-07-05:
 *  Removed lavc and fame encoder to be compatible with new libvo style.
 *  Added graphic equalizer support.
 *
 * 2002-04-15:
 *  The spuenc code isn't 100% stable yet, therefore I'm disabling
 *  it due to the upcoming stable release.
 *
 * 2002-04-03:
 *  Carl George added spuenc support
 *
 * 2002-03-26:
 *  XorA added an option parser and support for selecting encoder
 *  codec. We thank him again.
 *
 * 2002-03-25:
 *  A couple of bugfixes by XorA
 *
 * 2002-03-23:
 *  Thanks to Marcel Hild <[e-mail]> the jitter-bug experienced
 *  with some videos have been fixed, many thanks goes to him.
 *
 * 2002-03-16:
 *  Fixed problems with fame, it gives a better picture than avcodec,
 *  but is slightly slower. Most notably the wobbling effect is gone
 *  with fame.
 *
 * 2002-03-13:
 *  Preliminary fame support added (it breaks after seeking, why?)
 *
 * 2002-02-18:
 *  Fixed sync problems when pausing video (while using prebuffering)
 *
 * 2002-02-16:
 *  Fixed bug which would case invalid output when using :noprebuf
 *  Removed equalization code, it caused problems on slow systems
 *
 * 2002-02-13:
 *  Using the swscaler instead of the old hand coded shit. (Checkout man mplayer and search for sws ;).
 *  Using aspect function to setup a proper mpeg1, no more hassling with odd resolutions or GOP-sizes,
 *  this would only create jitter on some vids!
 *  The swscaler sometimes exits with sig8 on mpegs, I don't know why yet (just use -vc mpegpes in this
 *  case, and report to me if you have any avi's etc which does this...)
 *
 * 2002-02-09:
 *  Thanks to the new control() method I have finally been able to enable the em8300 prebuffering.
 *  This should speed up playback on all systems, the vout cpu usage should rocket since I will be hogging
 *  the pci bus. Not to worry though, since frames are prebuffered it should be able to take a few blows
 *  if you start doing other stuff simultaneously.
 *
 * 2002-02-03:
 *  Removal of libmp1e, libavcodec has finally become faster (and it's code is helluva lot cleaner)
 *
 * 2002-02-02:
 *  Cleaned out some old code which might have slowed down writes
 *
 * 2002-01-17:
 *  Testrelease of new sync engine (using previously undocumented feature of em8300).
 *
 * 2002-01-15:
 *  Preliminary subpic support with -vc mpegpes and dvd's
 *  Device interfaces tries the new naming scheme by default (even though most users probably still use the old one)
 *
 * 2002-01-10:
 *  I rehauled the entire codebase. I have now changed to
 *  Kernighan & Ritchie codingstyle, please mail me if you 
 *  find any inconcistencies.
