// By default WebRTC provides an implementation of field trials that can be
|
||||
// found in system_wrappers/source/field_trial.cc. If clients want to provide
|
||||
// a custom version, they will have to:
|
||||
//
|
||||
// 1. Compile WebRTC defining the preprocessor macro
|
||||
// WEBRTC_EXCLUDE_FIELD_TRIAL_DEFAULT (if GN is used this can be achieved
|
||||
// by setting the GN arg rtc_exclude_field_trial_default to true).
|
||||
// 2. Provide an implementation of:
|
||||
// std::string webrtc::field_trial::FindFullName(absl::string_view trial).
|
||||
//
|
||||
// They are designed to wire up directly to chrome field trials and to speed up
|
||||
// developers by reducing the need to wire APIs to control whether a feature is
|
||||
// on/off. E.g. to experiment with a new method that could lead to a different
|
||||
// trade-off between CPU/bandwidth:
|
||||
//
|
||||
// 1 - Develop the feature with default behaviour off:
|

//
|

// if (FieldTrial::FindFullName("WebRTCExperimentMethod2") == "Enabled")
|
||||
// method2();
|
||||
// else
|
||||
// method1();
|
||||
//
|
||||
// 2 - Once the changes are rolled to chrome, the new code path can be
|
||||
// controlled as normal chrome field trials.
|

//
|
||||
// 3 - Evaluate the new feature and clean the code paths.
