Hi, Regarding below patch - HEIF/HEIC image encoding uses HEVC/AVC encoders and client can set image quality level using V4L2_CID_MPEG_VIDEO_FRAME_QUALITY control. Reference BITRATE_MODE_CQ at https://developer.android.com/reference/android/media/MediaCodecInfo.EncoderCapabilities#BITRATE_MOD

[PATCH] media: v4l2-ctrls: Add encoded frame quality controls

When frame quality control is enabled encoder will choose the appropriate quantization parameter and bitrate to produce the client requested frame quality level. When frame quality control is disabled then frame quality is decided based on appropriate controls (i.e. V4L2_CID_MPEG_VIDEO_FRAME_RC_ENA
