/*
* vo_dxr3.c - DXR3/H+ video out
*
* Copyright (C) 2002 David Holm <dholm@iname.com>
*
*/
/* ChangeLog added 2002-01-10
* 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.
