2004-05-29separate the two semantics of querying a port's status with a NULL stream;Michael Roitzsch
before, NULL could mean two things: no stream at all or a stream that does not want to be addressed; now the latter is represented by the new XINE_ANON_STREAM resulting changes: * the status() functions now behave differently for NULL and XINE_ANON_STREAM (as the commentary always implied, but this was not the case, so post plugin rewiring went wrong, because it relies on the status() function) * the NULL_STREAM defines in audio_out and video_out are obsolete * update the function comments in the headers * update the post plugin rewire functions to use the status() functions to check, if the old port was opened and handle the new one accordingly; this makes open_count obsolete * change all post plugins accordingly (mostly using XINE_ANON_STREAM instead of NULL) additional change: * the status() function of audio port now returns the bits/rate/mode values of the input and not the output; this is more likely to be what a post plugin wants * the reimplementation of status() in the upmix plugin is obsolete CVS patchset: 6603 CVS date: 2004/05/29 14:45:25
2004-05-18track number of times the port has being opened.Miguel Freitas
rewiring a closed port won't cause the new destination to be opened. CVS patchset: 6564 CVS date: 2004/05/18 03:16:12

2004-01-07the new, refined post plugin architectureMichael Roitzsch
* post plugins are now much safer (fewer races/inconsistencies) and easier to write * all post plugins are ported to the new architecture (and should work) * ports can now be opened and closed with a NULL stream CVS patchset: 6007 CVS date: 2004/01/07 19:52:42

2003-11-26the viz plugins are feeding their private metronom with video only data, soMichael Roitzsch
have_video=1, have_audio=0 seems more logical CVS patchset: 5791 CVS date: 2003/11/26 19:30:14
2003-11-20"Anti audio fifo null" patch ;)Thibaut Mattern
Makes things a bit more symetric: - the audio fifo (demuxer->decoder) can't be NULL - the video driver can be NULL A dummy fifo (5 buffers) is used if the audio driver or video driver is NULL. Audio frontends (rhythmbox, seedeexeen, quark) do not need to instanciate a video driver anymore. CVS patchset: 5767 CVS date: 2003/11/20 00:42:14

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

Fix strange problems with viz plugins. CVS patchset: 4716 CVS date: 2003/04/30 06:58:50
2003-03-11Several post plugins were crashing with a failed assertion, due toJuergen Keil
closing a bogus xine_video_port_t: xine-lib/src/xine-engine/audio_out.c:fifo_append_int:225: assertion `!buf->next' failed. Next audio buffer is not NULL. CVS patchset: 4395 CVS date: 2003/03/11 17:40:30
2003-02-22handle extra info properly; that is: the inverter should pass on the extra info,Michael Roitzsch
the vis plugins should invalidate the extra info of the frames they output to not interfere with the (correct) extra info which will be set by audio out CVS patchset: 4250 CVS date: 2003/02/22 14:21:37

2003-01-14yet another glue logic for viz plugins. that should fix problems withMiguel Freitas
jumbo audio buffers (several seconds). unfortunately it requires an extra data copy, but i don't think that will make any perceptible difference. CVS patchset: 3916 CVS date: 2003/01/14 21:00:23
2003-01-05testing new logic for visualization plugins. this code should be portedMiguel Freitas
to other plugins after some test/cleanup. unfortunately we must support three cases here: 1) decoders that send data in small chunks, data must be accumulated between multiple audio frames to generate a single video frame (eg: wav). 2) good sized decoder chucks, the naive approach of 1:1 audio/video frames mapping usually works fine (eg: mp3) 3) very big decoder chunks. a single audio frame must generate several video frames (eg: wma) btw: mike, nice work on oscope!!
