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
2002-12-22flush/seeking overhauledMiguel Freitas
- move frame discarding to inside the output loopss. it is much safer to manipulate fifos from there avoiding any races. - do not reject audio frames because vpts is smaller than previous. it might happen on seeking but it's ok, because the sound driver may have being flushed too. - fix xine_demux_flush_engine so it doesn't call output flush too early - remove scr adjusting please report any problems...

CVS patchset: 3608 CVS date: 2002/12/21 16:12:25
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
2002-12-14The solaris pthread_cond_init() man page tells me:Juergen Keil
Attempting to initialize an already initialized condition variable results in undefined behavior. fifo->not_empty was initialized in fifo_new(); there should be no need to re-initialize it in fifo_remove_int().. CVS patchset: 3519 CVS date: 2002/12/14 16:33:59

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

found in laptops, supporting only 16 bits, only stereo etc). as added bonus of new "stackable" conversion scheme fixes resampling for 8 bit streams.

2002-04-29Replace all exit(1) with abort().James Courtier-Dutton
xine-lib should really never do an exit or abort, but instead pass back nice error values to the calling application, but until that happens, use abort() as that is tracable with gdb, whereas exit(1) is not backtraceable. CVS patchset: 1811 CVS date: 2002/04/29 23:31:59

CVS patchset: 1572 CVS date: 2002/03/16 13:25:05
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
