+Subject: [PATCH] [gst-plugins-good 1.16.3]v4l2h264enc:Add Extended controls
+ support for H264 encoder
+
+Add extended controls such as video bitrate,
+gopsize and iperiod for H264 encoder.
+
+Upstream-Status: Submitted [https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/1010]
+Signed-off-by: Sidraya Jayagond <sidraya.bj@pathpartnertech.com>
+---
+Raised merge-request to upstream and still discussion is in progress.
+
+Working on to add following controls to complete the upstream of the patch.
+1. GOP closure.
+2. Add and expose controls of VBR and CBR.
+
+Currently backported this patch to 1.16.3 version, As it requires
+to be in dunfell baseline for TI SDK.
