2003-11-15start xine_stream_t separation (public/private).Miguel Freitas
(we should finish this before rc3.) - stream_info and meta_info variables are private now. obs: everything must be recompiled due xine_stream_t changes CVS patchset: 5733 CVS date: 2003/11/15 14:54:30
2003-11-11rename internal API function (_x_<function>).Daniel Caujolle-Bert
CVS patchset: 5721 CVS date: 2003/11/11 18:44:50
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
2003-09-01Add proper support for 4.1 and 5 channel setups.James Courtier-Dutton
For 4.1, the output comes out on 3 stereo jacks, but the Center has been mixed with the Front speakers. For 5, the LFE channel has been dropped. CVS patchset: 5324 CVS date: 2003/09/01 04:08:41
2003-08-26add a mechanism to force closing audio device without stoping stream.Miguel Freitas
this is useful for (1) pausing the playback, (2) let another application use the sound card, and then (3) unpause it again. also add new "format" field to audio buffer (just like we have for frames) CVS patchset: 5312 CVS date: 2003/08/26 21:18:32

2003-02-01adding flush-mode so seek() and play() work for video processing (enix)Guenter Bartsch
CVS patchset: 4080 CVS date: 2003/02/01 19:22:30
2003-01-11introducing a new, very low-impact aproach on implementing a video ↵Guenter Bartsch
processing api CVS patchset: 3875 CVS date: 2003/01/11 19:06:52
2002-12-27quite experimental changes on post plugin api to enable rewiringMiguel Freitas
of streams. Michael, please let me know if you have a better idea! :) CVS patchset: 3689 CVS date: 2002/12/27 03:40:07
2002-12-27small cleanup for extra_info_tMiguel Freitas
CVS patchset: 3688 CVS date: 2002/12/27 02:03:06
2002-12-26- cleanup internal interfaces for rewiringMiguel Freitas
- fix UI_PLAYBACK_FINISHED rifle CVS patchset: 3686 CVS date: 2002/12/26 21:53:41
2002-12-24discard buffers on flush so decoder will return faster. seeking should beMiguel Freitas
faster as well. (on a problematic stream i have, seeking time was reduced from 2.5s to 0.8s) CVS patchset: 3665 CVS date: 2002/12/24 14:00:55
2002-12-21- add buf->decoder_info_ptr: portability for systems where pointer hasMiguel Freitas
different sizeof than integer. - add extra_info structure to pass informations from input/demuxers down to the output frame. this can be used, for example, to pass the frame number of a frame (when known by decoder). also, immediate benefict is that we now have a slider which really shows the current position of the playing stream. new fields can be added to extra_info keeping binary compatibility - bumpy everybody's api versions CVS patchset: 3603 CVS date: 2002/12/21 12:56:44
2002-11-30just now i realized the wrong underlying assumption i did in metronom: fixingMiguel Freitas
audio drift the same way i did for video doesn't work, since sound card won't play it slower or faster because of the vpts's. with this patch i hope to have definitely separated the 2 sources of audio drift: (1) nominal sample rate discrepancy to stream pts, (2) sound card drift to system clock. - revert feedback audio loop - updated metronom's audio drift - always do a full gap filling if needed CVS patchset: 3392 CVS date: 2002/11/30 22:09:42

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
2002-10-29engine improvementsMichael Roitzsch
- output fifo flushing - more sophisticated discontinuity handling - seek improvement by waiting for at least one frame CVS patchset: 3089 CVS date: 2002/10/29 16:02:43
2002-10-24fix identiation, implement an audio compressor filter (yeah, i know a big ↵Guenter Bartsch
concept for audio filter plugins is needed but sorry, this has been on my todo-list for too long) CVS patchset: 2990 CVS date: 2002/10/24 17:51:30
2002-10-17move open_plugin function (used to create new plugin instances) from the ↵Michael Roitzsch
plugin info struct to the plugin class struct small nerby change in libffmpeg decoder plugin: access to video_out/audio_out in decoders should now be done via the appropriate members in xine_stream_t CVS patchset: 2843 CVS date: 2002/10/17 17:43:41
2002-10-16introduce audio/video_driver_class_t, adapt oss audio output plugin, exclude ↵Guenter Bartsch
other audio output plugin from build process CVS patchset: 2841 CVS date: 2002/10/16 22:54:47
2002-10-16increase audio/video out plugin interface version numbers to avoid accidents ↵Guenter Bartsch
caused by old plugins lying around... remove all video output plugins except xv from build process for now CVS patchset: 2836 CVS date: 2002/10/16 14:19:38

broken now ... matthias/miguel: please fix it :-) CVS patchset: 2606 CVS date: 2002/09/04 23:31:05
2002-07-28introduce a config option for passthough offsetHeiko Schaefer
CVS patchset: 2362 CVS date: 2002/07/28 21:37:35
2002-07-01improved audio resampling for limited featured sound cards (like the ones ↵Miguel Freitas
found in laptops, supporting only 16 bits, only stereo etc). as added bonus of new "stackable" conversion scheme fixes resampling for 8 bit streams. (thanks Damien Clermonté for discussion and ideas) note1: alsa patch untested. note2: pass-through untested. CVS patchset: 2187 CVS date: 2002/07/01 13:51:26
2002-05-24some cleanups, mutex to protect driver access (unpredictable things mayMiguel Freitas
happen without it when using async functions), force_rate as integer CVS patchset: 1935 CVS date: 2002/05/24 12:23:58
2002-05-21better output buffer calculations (when resampling) by Ian GoldbergMiguel Freitas

CVS patchset: 1635 CVS date: 2002/03/26 01:47:17
2002-03-19improved buffering for audio-only streamsGuenter Bartsch
(wanna try? gnome-xine mms://live5-ms.unbn.unit.net/radio_project ) forced asx-parser back to a (hopefully) working state fixed warning about wrong audio_instance type CVS patchset: 1591 CVS date: 2002/03/19 02:12:49
2002-03-11Add a "control" method to the audio drivers, to allow pause/resume of theJuergen Keil
playback stream and to flush buffered samples from from the audio driver. (Currently implemented in the 'Sun' audio driver, + some untested code in the alsa 0.9 driver). The pause/resume method can be used by the engine to immediatelly stop playing buffered audio samples when the video is paused. Flushing buffered samples is useful when a video is stopped. And it'll be useful for better seeking support, too. CVS patchset: 1556 CVS date: 2002/03/11 19:58:00
2002-03-11metronom and demuxers should work again (although not all demuxers are fully ↵Guenter Bartsch
updated at this point). demux_qt can handle compressed audio, but is still unfinished. Yes, this _is_ the big metronom update, metronom now depends on disc_off information in discontinuities. CVS patchset: 1554 CVS date: 2002/03/11 12:31:24
2002-02-17big debug output cleanup. removed debug output from log window, loggingGuenter Bartsch
relevant information like stream type/size/bitrate instead. demuxer cleanup, removed no-longer-needed macros :-) switched off video_out/libmpeg2/... verbose log output messages. CVS patchset: 1503 CVS date: 2002/02/17 17:32:49
2002-02-09the long-awaited video_out changes, not completely debuged (races)Guenter Bartsch
- pts are 64 bit now - scr and video_out-loop run all the time - video_out cleanups - metronom cleanups - buffer type BUF_CONTROL_DISCONTINUITY is used internally now, input plugins should no longer send this one - support for individual frame durations - using nano-/usleep instead of itimer (simpler code, maybe this will help freebsd) CVS patchset: 1487 CVS date: 2002/02/09 07:13:22
