[xine-devel] 0.4.0 aproaching

[Guenter B. <bar...@st...>]

Hi folks,

once again sorry you don't hear much from me - but I can assure you, I'm
still alive and I'm working on xine. While I'm not yet ready to commit
anything I just wanted to give you a quick briefing about what I've done
and what changes will come until my 0.4.0alpha commit:

DONE
   - new audio_out interface, core of it looks like this:

/*
 * audio output modi
 */

#define AO_MODE_AC3      0
#define AO_MODE_MONO     1 /* 1 sample ==  2 bytes */
#define AO_MODE_STEREO   2 /* 1 sample ==  4 bytes */
#define AO_MODE_4CHANNEL 3 /* 1 sample ==  8 bytes */
#define AO_MODE_5CHANNEL 4 /* 1 sample == 10 bytes */

typedef struct ao_functions_s
{

  /*
   * find out if desired output mode is supported by
   * this driver
   */

  int (*is_mode_supported) (int mode);

  /*
   * init device - buffer will be flushed(!)
   */

  void (*open)(uint32_t bits, uint32_t rate, int mode);

  /*
   * write audio data to output buffer - may block
   * audio driver must sync sample playback with metronom
   */

  void (*write_audio_data)(int16_t* audio_data, uint32_t num_samples, 
                           uint32_t pts);

  /*
   * close the audio driver
   */

  void (*close)(void);

} ao_functions_t;

  - changed libmpg123 and libac3 to use new interface
  
  - cleaned up libmpg123's interface 

  - made video_out thread-safe

  - changed xine.c to use threads - xine_loop is gone,
    seperate video_loop, audio_loop instead

  - Siggi has implemented the master clock timer functions,
    I added his code to metronom.c/.h

TODO:

  - finish audio_oss_out to reflect interface changes (90% done)

  - adapt audio_alsa_out for new interface

  - get it all to compile

  - get it all to work

  - do a cvs update (*uaah* - that'll merge like hell 8-} )

  - get it all to compile again

  - get it all to work again

  - cvs commit and duck and cover to survive the flames 
    from xine_user about the latest CVS changes ("nothing works!" 
    "xine is broken!" ... ;)))

Regards,

   Guenter
