*
|
||||
* 30/03/02: An almost total rewrite, added DR support and support for modes
|
||||
* other than 16bpp. Fixed the crash when playing multiple files
|
||||
* 07/04/02: Fixed DR support, added YUY2 support, fixed OSD stuff.
|
||||
* 08/04/02: Fixed a wierd sound corruption problem caused by some optomizations
|
||||
* I made.
|
||||
* 09/04/02: Fixed a problem with changing the variables passed to draw_slice().
|
||||
* Fixed DR support for YV12 et al. Added BGR support. Removed lots of dud code.
|
||||
* 10/04/02: Changed the memcpy functions to mem2agpcpy.. should be a tad
|
||||
* faster.
|
||||
* 11/04/02: Added a compile option so you can watch the film with the console
|
||||
* as the background, or not.
|
||||
*
|
||||
* TODO:
|
||||
* - Add DR support (for stuff other than YUY2)
|
||||
* - Add UYVY support
|
||||
* - Add zoom support
|
||||
* - Remove some of the old dud code
|
||||
* Hints and tricks:
|
||||
* - Use -dr to get direct rendering
|
||||
* - Use -vop yuy2 to get yuy2 rendering, *MUCH* faster than yv12
