/**
 * Quirk denotes that the encoder should create new input surface for every encoding instead of
 * using {@link MediaCodec#createPersistentInputSurface()}.
 *
 * <p>{@link MediaCodec#createPersistentInputSurface()} is introduced on API 23, which creates a
 * reusable surface for multiple encodings and is the suggested approach. So for devices with API
 * 21 and 22, a new surface has to be created for every encoding instead.
 *
 * <p>As describe in b/202798966, there is a device that has API 23+, but the recorded video is
 * abnormal if using {@link MediaCodec#createPersistentInputSurface()}. Creating a new surface
 * for new recording resolve the issue, hence this quirk is also applied to the problematic devices.
