/**
 * <p>QuirkSummary
 *     Bug Id: 197805856, 280121263, 295060316
 *     Description: Quirk that denotes some devices use a timebase for camera frames that is
 *                  different than what is reported by
 *                  {@link android.hardware.camera2.CameraCharacteristics
 *                  #SENSOR_INFO_TIMESTAMP_SOURCE}. This can cause A/V sync issues.
 *     Device(s): Some Samsung devices and devices running on certain Qualcomm SoCs
 *     @see VideoTimebaseConverter
