+LibreMediaServer Changelog

 v 0.2.0 Antígona (26/05/2024)
 + Change audio engine to miniaudio because is imposible pan in SFML and it has not access to low API and audio processing.
@ -13,36 +13,38 @@ v 0.2.0 Antígona (26/05/2024)
 + Pan.
 + Show faders values. New SliderGroup class.
 + Entry Point 16 bits.
-+ Refactor AudioMasterWidget to AudioDMXReceptionWidget.
-+ Read mp3, flac, wav (mp3 has given some errors seeking cursor...).
+ Refactor AudioMasterWidget to dmxWidget.
+ Read mp3, flac, wav (mp3 has given some errors seeking cursors...). Audio Engine is working at 48Khz and 32 bits pcm float, if media files are encoding at same configuration, it saves a resampling operation later live.
 + Removed settings dialog, only read xml conf file at startup.
 + Real dynamic variable number of layers based on conf file setting.
 + OlaThread send double channels (volume, entry point, load media) only once for each dmx frame buffer.
 + Terminal mode without graphical interface. All audio methods has been refactorized out of QWidget world.
 + Compilation without GUI (-DNOGUI).
-+ New Status "Iddle" in playbacks if is not loaded.
 + New DMX personality version, better sort for audio needs (first load media, set vol, pan, etc, last playback order);
-+ Refresh layer values when it loads a new sound file.
-+ No QtSignals for sending data, better performance about 20% in my machine. Now, libremediaserver only updates values in AudioWidget, ui refresh is doing with a timer in audiowidget, so there is not problems between graphical and ola thread (the callback).

Signals are used only from Ui to libreMediaServer to notify user interactions and Qtimers.
 + Load media files from ui clicking in the media labels.
+ New Play Modes:
+    - Play all medias found in one folder.
+    - Play all medias in one folder consecutevily.
+    - Play all medias in one folder randomly.
+ Multi audio devices output.
+ Vumeter for each layer
+ Show device name on Ui and ouput bus slider.

 Libre Media Server Roadmap

-v  0.2.x
- skin, UI/UX
+v  0.3.0
+- Ui/Ux: skin, style.
+- Ui/Ux; Keyboards strokes.
+- Ui/Ux: Dar la opción clickeando en el widget de tiempo de poner una cuenta atrás en vez de hacia delante.
+- Ui/Ux: seek cursor playback
 - live input.
- insertar/bypass/eliminar audio procesadores sin reiniciar por capa y master. (compresor, equs).
- FX en capas master para que se puedan usar como envíos de auxiliar.
- Enroutado de masters en otros masters (retorno de efectos).
-
-v 0.2.2
- Use sACN directly.
+- remove ola and use sACN directly.
   + la instalación de OLA es mediante compilación, el repo de paquetes no está actualizado, nada user-friendly.
   + hay que empaquetar OLA, incluirlo en el binario, o implementar sACN y linkarlo estáticamente.
   + https://github.com/ETCLabs/sACN
 - Qt6.
- Audio processing (eq, rev, compresor, ...) by master and layer.
- CIPT/MSex, send icons play/pause/stop.
+- CIPT/MSex.
 - Rasp build.
 - Octopus Sound Card support (6 outputs - 8 inputs).
-
-v 0.2.1
- Multi devices output.
- Play Mode:
-    - Play all medias found in folder consecutevily or random, with loop.
-    - Play all medias, consecutevily and random, with loop.
- mute/panic on layer.
 - Master Bus Layer:
-    - each layer will have one "Gain" prefader that acts in source, "Vol" in v 1.3.
-    - each layer will have one volume dmx channel for each bus layer. One aux "Send" prefader.
    - mute/panic.
    - fader + value
-    - pan.
-    - magicq .hed
+    - pan
+    - magicq personality .hed
    - audio device linked, outputs will be redirected there.
    - dmx address + universe settings.
- Rose noise and sine generator in menu to test system.
- Ui/Ux; Keyboards strokes.
- Ui/Ux: Dar la opción clickeando en el widget de tiempo de poner una cuenta atrás en vez de hacia delante.
+    - compresor/limiter.
+- Layer:
+    - audio procesadores (compresor, reveb, delay).
+    - mute/panic.
+- Rose noise and sine generator.
 - Logs, verbosity, timestamp.
 - New play mode without pitch control, it saves resources. MA_SOUND_FLAG_NO_PITCH
 - SettingsDialog.
@ -49,6 +39,6 @@ v 0.2.1
 - ¿Exit Point? is it needed?
 - Hardening: check return errors, try/catch exceptions, i'm too happy....
 - Tests: errors on wrong conf file.
-
-v0.2.0:
- Vumeter or indicator about audio output in layer and master, add to sliderGroup.
+- ampliar writer para recibir un número n de entradas y escribirlas cada una en un buffer
+- aislar miniaudio del callback dmx tal como hemos hecho con la Ui, al menos las operaciones lentas como cargar medios.
+- en load media usar un fence para actualizar mediaLoaded.

snt	5d56921aeb	refactorizado todo a una struct. Maximo de dispositivos MAX_AUDIODEVICES, sin testear mas de dos. Los devices auxiliares leen de data source rb en vez de en el callback. la idea del nodegraph funcionando en una engine dummy no ha funcionado, pero puede que fuera por la refactorización y la introducción de las data sources rb. Ahora que está todo más ordenado se puede volver a intentar. Pero tampoco merece mucho la pena, la principal diferencia era el master bus, pero se puede atacar la salida de auxNode[0] a una capa de master en vez de al endpoint directamente.	2024-05-20 19:00:05 +02:00
