Custom Decoder

+Demonstrates how to implement a custom decoder. +

+

+ +This example implements two custom decoders: +

+
    +
  • +
    • +
+
    +
  • +Vorbis via libvorbis +
    • +
  • +Opus via libopus + +A
    • +
+

+A custom decoder must implement a data source. In this example, the libvorbis data source is called +ma_libvorbis and the Opus data source is called ma_libopus. These two objects are compatible +with the ma_data_source APIs and can be taken straight from this example and used in real code. +

+

+ +The custom decoding data sources (ma_libvorbis and ma_libopus in this example) are connected to +the decoder via the decoder config (ma_decoder_config). You need to implement a vtable for each +of your custom decoders. See ma_decoding_backend_vtable for the functions you need to implement. +The onInitFile, onInitFileW and onInitMemory functions are optional.

+
+#define MA_NO_VORBIS    /* Disable the built-in Vorbis decoder to ensure the libvorbis decoder is picked. */
