From 66f92c4e1701d9d3c8b97503bd3aeb614a441a62 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 18 Mar 2020 19:36:49 +0100 Subject: media: coda: add RC enable controls Currently the encoder enables the rate control algorithms if the bitrate control is non-zero. Implement the V4L2_CID_MPEG_VIDEO_FRAME_RC_ENABLE and V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE controls to allow userspace to choose frame-level or macroblock-level rate control updates, or to explicitly disable rate control. Both controls are initially enabled to keep the current behavior.
