| <!-- Overview. |
| This example config file was copy from existing one: frameworks/av/media/libeffects/data/ |
| audio_effects.xml, with effect library names updated to AIDL libraries we currently have. |
| |
| All "library" attributes in "effect" element must must match a "library" element with the |
| same value of the "name" attribute. |
| All "effect" attributes in "preprocess" and "postprocess" element must match an "effect" |
| element with the same value of the "name" attribute. |
| |
| AIDL EffectFactory are relying on the "name" attribute in "effect" element to identify the |
| effect type, so it's necessary to have the mapping from name to effect type UUID. Make |
| sure to either use existing effect name as key of |
| ::android::hardware::audio::effect::kUuidNameTypeMap, or add a new {name, typeUUID} map |
| item to the kUuidNameTypeMap. |
| |
| Existing audio_effects.xml should working without any change as long as: |
| 1. "path" attribute of "library" element matches with the actual effect library name. |
| 2. "name" attribute of "effect" and "effectProxy" element correctly added as key of |
| kUuidNameTypeMap, with value matches Identity.type in Descriptor.aidl. |
| 3. "uuid" attribute of "effect" element matches Identity.uuid in Descriptor.aidl. |
| 4. "uuid" attribute of "effectProxy" element matches Identity.proxy in Descriptor.aidl. |

| <!-- list of effects to load. |
| Each "effect" element must contain a "name", "library" and a "uuid" attribute. |
| The value of the "library" attribute must correspond to the name of one library element in |
| the "libraries" element. |
| The "name" attribute used to specific effect type, and should be mapping to a key of |
| aidl::android::hardware::audio::effect::kUuidNameTypeMap. |
| The "uuid" attribute is the implementation specific UUID as specified by the effect vendor. |
| |
| Effect proxy can be supported with "effectProxy" element, each sub-element should contain |
| "library" and "uuid" attribute, all other attributes were ignored. Framework side use |
| result of IFactory.queryEffects() to decide which effect implementation should be part of |
| proxy and which not. |
| |
| Only "name", "library", and "uuid" attributes in "effects" element are meaningful and |
| parsed out by EffectConfig class, all other attributes are ignored. |
| Only "name" and "uuid" attributes in "effectProxy" element are meaningful and parsed out |
| by EffectConfig class, all other attributes are ignored. |
