From 569811160561225d05b945d829ab831b87a044b1 Mon Sep 17 00:00:00 2001 From: Andrey Utkin Date: Tue, 8 Jul 2014 12:23:32 -0300 Subject: [PATCH] [media] solo6x10: expose encoder quantization setting as V4L2 control solo6*10 boards have configurable quantization parameter which takes values from 0 to 31, inclusively. This change enables setting it with ioctl VIDIOC_S_CTRL with id V4L2_CID_MPEG_VIDEO_H264_MIN_QP.
