2003-07-20Improve playback on USB sound cards.James Courtier-Dutton
These changes improve xine's response to the removal of a USB cable while playing audio. Further changes will need to happen so as to allow sound output to continue when the USB cable is plugged back in, without having to stop the media stream. To enable that, when xine detects that the sound card is not there any more, it will have to close both pcm and mixer, so that the kernel can release USB resources, then when the USB cable is plugged back in, the pcm and mixer are opened again. This code might also modify what xine does in underrun situations, so this code might need to be changed again. CVS patchset: 5196 CVS date: 2003/07/20 10:34:29

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

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...

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
