2007-01-28fix integer/double mistake.Miguel Freitas
funny because the "more accurate" frame duration calculation actually broke a/v sync for ntsc dvds. tsc tsc ;-) fixes #1544349, #1589644 CVS patchset: 8574 CVS date: 2007/01/28 22:46:07

improve xxmc cpu-usage for IDCT / MOCOMP acceleration through better locking [bug #1195282] CVS patchset: 7524 CVS date: 2005/05/06 07:42:20
2005-05-03**BUGFIX**Thomas Hellström
Fixed xvmc plugin segfault when it tried software blending on nonexistant xv image. Cleaned up libmpeg2 behaviour on xxmc plugin abrupt software fallback. CVS patchset: 7516 CVS date: 2005/05/03 19:25:10
2005-04-09**BUGFIX**Thomas Hellström
Multiple slice-per-rows (HDTV) fixes in the libmpeg2 code, particularly regarding VLD XvMC. Cleaned up hardware acceleration hooks in libmpeg2. Fixed X include path searching while configure detects XvMC support. CVS patchset: 7449 CVS date: 2005/04/09 11:22:14
2005-02-22XvMC update largely courtesy of Kendall Bennet, Scitechsoft:Thomas Hellström
* Fix surface flushing and syncing (xxmc / xvmc) * Fix clearing of macro block lists (xxmc / xvmc) * Remove floating point operations from mpeg demuxer. Degrades performance on non-fp capable hardware. * Remove unnecessary software MC step * Fix Quantization matrix ordering which caused bad picture quality (KB/TH) * Minor optimizations in the libmpeg2 code * Fix VLD flushing at video discontinuity (TH) CVS patchset: 7424 CVS date: 2005/02/22 18:31:33
2005-01-30**BUGFIX**Thomas Hellström
Bug 1092411 Makes XvMC handle cases where each slice is split into more than two parts. This got broken on IDCT / MOCOMP with a previous commit to fix a search segfault. Has never worked before with VLD. Still IDCT / MOCOMP exhibit bad picture quality in this case but not worse than before it got broken. CVS patchset: 7375 CVS date: 2005/01/30 18:01:25

2004-10-12xxmc driver updates:Thomas Hellström
Updated software fallback mechanism to be compatible with post plugin deinterlacing. A decoder using the plugin can now request a software fallback format to be used if acceleration fails. Removed the software deinterlacer that was inherited from the xv plugin. Made idct/mocomp fall back to software decoding for interlaced streams, since these are not rendered correctly either with the xvmc or the xxmc plugin. CVS patchset: 7029 CVS date: 2004/10/12 07:40:07
2004-09-28xxmc patch by Thomas Hellstrom (with some changes)Miguel Freitas
there is still some work to do, please report any breakages. note: new xxmc driver tested with both nvidia and via libraries. CVS patchset: 7007 CVS date: 2004/09/28 18:49:38
2004-09-22- added cropping capability (thanks James Stembridge)Miguel Freitas
- some vo drivers support cropping natively. (only xv and xvmc have been tested) - add software crop fallback to video_out.c - skip yuv2rgb processing at xshm for not yet cropped frames (these frames are never shown) - libmpeg2 and ffmpeg now may use crop support - bump vo api. (changes to xvmc/xxmc will follow) CVS patchset: 6991 CVS date: 2004/09/22 20:29:13

BIG NOTE: use helpers to access to these informations (get/set/reset): _x_{stream,meta}_info_{get,set,reset}() are for internal use, don't use *_public() ones from inside the beast ;-) Some wrongly names "xine_" fonction renaming. CVS patchset: 5757 CVS date: 2003/11/16 23:33:42

2003-06-11- add VO_INTERLACED_FLAG to get_frameMiguel Freitas
- do not trust progressive_frame for detecting NTSC 3:2, quote: 'the alternating progressive_frame encoding problem. This is a problem where the progressive_frame flag alternates between true and false every frame, when it really should have been set to "true" all the time.' 'There is a lot of content that is affected by this issue, because it's caused by a dumb decision by a very big company that made a very popular MPEG encoder. They've since fixed the encoder, but there are apparently still authoring companies that use it, because the problem is on a lot of high-profile current discs, like Disney's "Monsters Inc." and "Beauty and the Beast".' http://www.hometheaterhifi.com/volume_8_2/dvd-benchmark-special-report-chroma-bug-4-2001.html CVS patchset: 5025 CVS date: 2003/06/11 23:08:54

stream but just do not output any frames some DVD menus, where is_frame_needed seems to skip something important for decoding should work now, while we should still see no artifacts on seeking CVS patchset: 4470 CVS date: 2003/03/23 14:58:33
2003-03-17fix decoder reset: when waiting for I and P frames, to get the necessary ↵Michael Roitzsch
reference frames, we have to evaluate the frame types earlier, because on some DVDs with interlaced NTSC material, the fields of the frames are interwoven in a way that would overwrite the frame type with a new value before we evaluate it, this leads to xine endlessly waiting for I or P frames. enabling seek_mode on decoder reset also fixes some seeking artifacts CVS patchset: 4437 CVS date: 2003/03/17 15:25:10

2002-11-20engine modifications to allow post plugin layer:Michael Roitzsch
* new public output interface xine_{audio,video}_port_t instead of xine_{ao,vo}_driver_t, old names kept as aliases for compatibility * modified the engine to allow multiple streams per output * renaming of some internal structures according to public changes * moving SCR out of per-stream-metronom into a global metronom_clock_t residing in xine_t and therefore easily available to the output layer * adapting all available plugins (note to external projects: the compiler will help you a lot, if a plugin compiles, it is adapted, because all changes add new parameters to some functions) * bump up all interface versions because of xine_t and xine_stream_t changes CVS patchset: 3312 CVS date: 2002/11/20 11:57:38
