2003-04-13make compressor disabled by default. it was burning cpu ciclesMiguel Freitas
after setting AMP level. played a xvid+ac3 stream measuring function time with oprofile: audio_filter_amp_compress 64.63% (relative to total libxine.so time) for comparison: xine_fast_memcpy 13.27% CVS patchset: 4609 CVS date: 2003/04/13 22:19:08

2003-02-28Xine assert() replacement:Stephen Torri
All assert() function calls, with exceptions of libdvdread and libdvdnav, have been replaced with XINE_ASSERT. Functionally XINE_ASSERT behaves just likes its predecesor but its adding the ability to print out a stack trace at the point where the assertion fails. So here are a few examples. assert (0); This use of assert was found in a couple locations most favorably being the default case of a switch statement. This was the only thing there. So if the switch statement was unable to find a match it would have defaulted to this and the user and the developers would be stuck wonder who died and where. So it has been replaced with XINE_ASSERT(0, "We have reach this point and don't have a default case"); It may seem a bit none descriptive but there is more going on behind the scene. In addition to checking a condition is true/false, in this case '0', the XINE_ASSERT prints out: <filename>:<function name>:<line number> - assertion '<assertion expression>' failed. <description> An example of this might be: input_dvd.c:open_plugin:1178 - assertion '0' failed. xine_malloc failed!!! You have run out of memory XINE_ASSERT and its helper function, print_trace, are found in src/xine-utils/xineutils.h CVS patchset: 4301 CVS date: 2003/02/28 02:51:47

tested with asf, avi and mpeg but any media should work. todo: - clean up the master/slave stuff and public api. - implement seeking on demux_sputext.c (it must seek to closest subtitle) - general cleaning up and bugfixing CVS patchset: 3860 CVS date: 2003/01/11 03:47:01

set it on send_headers. also daniel convinced me that xine does "handle a no audio stream" - fix audio_out.c to abort filling with zero on seeking/stop/quit. CVS patchset: 3840 CVS date: 2003/01/09 02:44:39

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
