/**
* Quirk which denotes {@link MediaCodecInfo} queried by {@link MediaCodecList} returns incorrect
* info.
*
* <p>On Nokia 1, {@link CamcorderProfile} indicates it can support resolutions 1280x720 and
* 640x480 for video codec type {@link android.media.MediaRecorder.VideoEncoder#MPEG_4_SP}, which
* maps to mime type "video/mp4v-es".
* The {@link MediaCodecInfo} searched by {@link MediaCodecList#getCodecInfos()} shows the
* maximum supported resolution of "video/mp4v-es" is 174x174. Therefore,
* {@link MediaCodecList#findEncoderForFormat} cannot find any supported codec by
* the resolution provided by {@code CamcorderProfile} because it internally use
* {@code MediaCodecInfo} to check the supported resolution. By testing,
* "video/mp4v-es" with 1280x720 or 640x480 can be used to record video. So the maximum supported
* resolution 174x174 is probably incorrect for "video/mp4v-es" and doesn't make sense.
* See b/192431846#comment3.
*
* <p>On Huawei Mate9, {@link CamcorderProfile} indicates it can support resolutions 3840x2160 for
* video codec type {@link android.media.MediaRecorder.VideoEncoder#HEVC}, but the current video
* codec type is default {@link android.media.MediaRecorder.VideoEncoder#H264}.
* Even, change video codec type to {@link android.media.MediaRecorder.VideoEncoder#HEVC}, it
* still meet unsupported resolution for 3840x2160, it only support 3840x2112. By experimental
* result, H.264 + 3840x2160 can be used to record video on this device. Hence use quirk to
* workaround this case. See b/203481899#comment2.
