/**
 * Quirk requiring that the frame rate is not set on the MediaFormat during codec selection.
 *
 * <p>QuirkSummary
 *      Bug Id:      174630237
 *      Description: According to the documentation for
 *                   {@link android.media.MediaCodecList#findEncoderForFormat(MediaFormat)}, on
 *                   devices exhibiting this quirk, the {@link MediaFormat} argument must not
 *                   contain {@link MediaFormat#KEY_FRAME_RATE}, so special care must be taken to
 *                   remove this key before using the API to find the codec, but the frame rate
 *                   key may still be required to configure the codec correctly.
 *      Device(s):   All devices running Lollipop (API 21)
 *
 * @see <a href="https://developer.android.com/reference/android/media/MediaCodec#creation">
 *     MediaCodec Creation</a>
