2003-12-24thanks to Carsten Weinhold for finding and fixing this:Michael Roitzsch
pthread locks are _not_ fair (shocking news for me), so audio out has a problem: the audio out loop holds the driver_lock almost always (since the write() to the driver takes most of the time); other threads who want that lock (like the frontend trying to change the volume) can starve; the problem shows on kernel 2.6 with NPTL, but the potential is there in all pthread implementations CVS patchset: 5938 CVS date: 2003/12/24 13:06:10

2003-12-07get rid of XINE_{ASSERT,ABORT} and useless xine_print_trace (useless). ↵Daniel Caujolle-Bert
Replace XINE_ASSERT by _x_assert, which works exaclty as assert, except that it still warns with NDEBUG defined (but don't abort). Fix missuning of assert(0), which isn't safe, abort is abort, assert is for debugging purpose only, so all assert(0) has been converted to abort() alls. In osd_preload_fonts(): alloc needed memory chunk. Define NDEBUG in CFLAGS, for non DEBUG build only. CVS patchset: 5860 CVS date: 2003/12/07 15:34:29
2003-12-05cleanup phase II. use xprintf when it's relevant, use xine_xmalloc when it's ↵Daniel Caujolle-Bert
relevant too. Small other little fix (can't remember). Change few internal function prototype because it xine_t pointer need to be used if some xine's internal sections. NOTE: libdvd{nav,read} is still too noisy, i will take a look to made it quit, without invasive changes. To be continued... CVS patchset: 5844 CVS date: 2003/12/05 15:54:56

2003-11-16New stream/meta info (safe) stuff.Daniel Caujolle-Bert
BIG NOTE: use helpers to access to these informations (get/set/reset): _x_{stream,meta}_info_{get,set,reset}() are for internal use, don't use *_public() ones from inside the beast ;-) Some wrongly names "xine_" fonction renaming. CVS patchset: 5757 CVS date: 2003/11/16 23:33:42

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

2003-09-01Add 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

CVS patchset: 5199 CVS date: 2003/07/20 12:29:18
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
