2009-01-18Remove '#include "config.h"' from all public header files.Darren Salt
This requires that many other files include config.h themselves. Also convert <config.h> to "config.h".
2008-05-23Mark initialisation functions with malloc attribute.Diego 'Flameeyes' Pettenò
All the initialisation functions returning a new object instance that was allocated through malloc() or calloc() can get the malloc attribute so that the compiler can optimise their call.
2007-12-27[Subtitles] SSA-tags patchDubois Nicolas
I watch a lot of movies with subtitles and I need "vobsub subtitles" work in xine, then I decide to write this patch. It may support SSA tags for all text subtiles (ssa, ass, srt, ...) This patch : 1. Remove all SSA tags from stream (they are ugly : {\a6}) 2. Handle some of them (b, i, a, an, pos). The other ones control colours, shadow, animation, ... I can't make them work in an easy way. 3. Correct wrap algorithm which have minors bugs (we can see them only with SSA patch...) Modified files : libsputext/demux_sputext.c just remove unneeded code (which remove some of SSA-tags) libsputext/xine_sputext_decoder.c the main modified file. video_out/video_out_xshm.c video_out/video_out_xv.c xine-engine/video_out.h get video output (position and size). See below. 1. Removing SSA tags is done in ogm_render_line_internal() like for html-like tags. (this was done in the previous version of xine) 2. b(bold) and i(italic) are implemented like html-ones, in ogm_render_line_internal(). The other tags this patch support are : aX : alignment in SSA-code anX : alignment in numpad code pos(X,Y) : position, depend on alignment For those ones, I need in first a full-screen OSD, not a five lines one. Then, I need to remember where the last subtitle was drawn, in order to erase it. At last, I need a translation function to convert subtitle coordinates in screen coordinates. For this last point, I first write a full-screen translation (don't care about blacks borders), but it's not really good: the 'pos' tag is sometime used to point out something in the video. (Moreover, ASS spec say we have to draw subtitle on the video) For doing this, I need the real video output size and position, which are only know by the video output driver! Then I had 4 VO properties (in xine-engine/video_out.h) for video driver could give us those informations. I implement it only in xshm and xv drivers (I can't test other ones). If video driver can't give us those informations, the patch fallback in a full-screen translation. 3. there was 3 problem with the wrap algorithm : 1. It was in double: exactly the same, twice. Look like a merge problem. I remove one and all work fine. 2. It want to cut string in equivalent display length but it cut it in equivalent byte length. In most cases, this is the same, but if we have UTF-8 chars or long SSA-tags (which will not be displayed) the result is strange. 3. If we have a too-long part (in bytes) of the string without spaces (bad subtitle file or long SSA-code), the algorithm don't know what to do. (this case is not handled) I re-write the wrap algorithm to correct those problems. Note that my version is slower than previous one : working with bytes is really faster than computing text-length. Maybe I should had to propose an other patch for this part...

2007-04-18Alphablending optimizations:Petri Hintukainen
- validate palette alpha values in overlay manager (one check / overlay / palette index) instead of checking every alpha value twice for every blended pixel in every frame - remove unneeded calculations - approximiate expensive integer divisions with multiplication and shift
2006-09-26Use protected visibility for all the functions exported by libxine.so, so ↵Diego 'Flameeyes' Pettenò
that their binding is local to the library (has a similar effect to -Bsymbolic, but will work better with hidden visibility enabled, that is step two). CVS patchset: 8289 CVS date: 2006/09/26 05:19:47
2005-09-24- rename all clip_top, clip_left, clip_color... to hili_xxxx. thatMiguel Freitas
"clip" thing has caused too much confusion already since these variables define a highlight area. - add overlay offset support to video_out.c/alphablend/vo drivers - use overlay offset to implement proper croping of frames when vo driver doesn't support it - add clipping checks to alphablend to avoid buffer overflow, buffer "underflow" and wrapping. - increase vo api number - note: dxr3 support is incomplete about overlay offset CVS patchset: 7739 CVS date: 2005/09/24 19:08:26
2004-10-08change variable logic slightly to make it more clear that Miguel is a geniusMichael Roitzsch
and this code is correctly understood by me ;) also fall back to old behaviour (no cropping at all), if the image cannot be cropped due to an unknown frame format CVS patchset: 7024 CVS date: 2004/10/08 21:08:26
2004-09-28xxmc patch by Thomas Hellstrom (with some changes)Miguel Freitas

2004-09-26 - almost finalize headers refactoring needed for MSVC frontends (and for otherFrantišek Dvořák
poor platforms, of course) - fix a bug in generated xine-config for WIN32 and make it relocateable under Windows - MSVC port: update, fix some warnings, remove old unneeded files - improve function for getting runtime directory, it will need next fix yet (bug probably due to active volume drives) CVS patchset: 7001 CVS date: 2004/09/26 22:54:51
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
2004-07-06fix a long standing bug: streams were not played till their very end, becauseMiguel Freitas
finished event was sent to frontend before the output fifos were empty. add a test for the number of streams attached to the output port. this will prevent deadlocking on multi-streams scenarios where fifos don't ever get empty. CVS patchset: 6777 CVS date: 2004/07/06 22:53:22

2004-05-29separate the two semantics of querying a port's status with a NULL stream;Michael Roitzsch
before, NULL could mean two things: no stream at all or a stream that does not want to be addressed; now the latter is represented by the new XINE_ANON_STREAM resulting changes: * the status() functions now behave differently for NULL and XINE_ANON_STREAM (as the commentary always implied, but this was not the case, so post plugin rewiring went wrong, because it relies on the status() function) * the NULL_STREAM defines in audio_out and video_out are obsolete * update the function comments in the headers * update the post plugin rewire functions to use the status() functions to check, if the old port was opened and handle the new one accordingly; this makes open_count obsolete * change all post plugins accordingly (mostly using XINE_ANON_STREAM instead of NULL) additional change: * the status() function of audio port now returns the bits/rate/mode values of the input and not the output; this is more likely to be what a post plugin wants * the reimplementation of status() in the upmix plugin is obsolete CVS patchset: 6603 CVS date: 2004/05/29 14:45:25
2004-01-07the new, refined post plugin architectureMichael Roitzsch
* post plugins are now much safer (fewer races/inconsistencies) and easier to write * all post plugins are ported to the new architecture (and should work) * ports can now be opened and closed with a NULL stream CVS patchset: 6007 CVS date: 2004/01/07 19:52:42

2003-10-30* modify the engine slightly, so that the stream member in a video frame orMichael Roitzsch
audio buffer can be NULL; this should be used to indicate that the frame/ buffer does not come directly from a stream, but was generated otherwise (the most important result is that frames/buffers with stream NULL will not be passed through metronom) * modify visualization post plugins so they set the stream on the generated frames to NULL, this avoids cluttering metronom, when playing a stream with audio AND video AND a visualization post * this also means modifying the way post plugins provide vpts values: they have to calculate them themselves for now CVS patchset: 5647 CVS date: 2003/10/30 22:40:53
2003-10-23cleanup in video_out.hMichael Roitzsch
* some obsolete VO_CAP_* constants removed * VO_ZOOM_* constants replaced by their XINE_VO_ZOOM_* equivalents from xine.h * moved some bits around * proc_frame() needs only one parameter: the frame * renamed copy_called to proc_called * changed logic in video_out.c to call proc_* functions a bit (call proc_frame() first, then call proc_slice() if proc_frame() has not set proc_called, this allows video out plugins to have both hooks called) CVS patchset: 5576 CVS date: 2003/10/23 15:17:06

2003-08-15I am using the latest internal API increase to rename video_overlay_instace toMichael Roitzsch
video_overlay_manager, because a) this thing is called "overlay manager" by everyone b) the term "instance" is misleading, since it suggests that you would not share the outcome of a get_instance() with others CVS patchset: 5288 CVS date: 2003/08/15 14:35:09

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
