The following 2 patches enables the user to provide user defined profile for the video encoding using Gstreamer.

Board: J721e (TDA4VM)

SDK Version: 8.4

Patch-1: To be applied to Gstreamer plugin.

Patch file Name: 0001-Added-H264-profiles-support-to-Gstreamer-Plugin-for-.patch

In order to apply the patch, the user needs to have a Yocto setup and for setting up Yocto, please refer to SDK Documentation. Once the Yocto build is ready, the Gstreamer plugin is found at the location:


The patch can be applied from this folder and changes are made to the files:

./sys/v4l2/gstv4l2h264enc.c and ./sys/v4l2/gstv4l2h264enc.h

Patch-2: To be applied to Linux Kernel

Patch file name:


Location of Linux Kernel:


Apply the patch from this folder and changes are made to the file:



Once both the patches are applied, the driver can be verified by the below command. Use profile=0 for Base, profile=2 for Main, profile=4 for High. For any other value, default Base profile is set.

$ gst-launch-1.0 videotestsrc pattern=ball do-timestamp=true num-buffers=100  ! video/x-raw, format=NV12, width=852, height=480, framerate=30/1 ! v4l2h264enc profile=2 ! h264parse ! mp4mux ! filesink location=demo_main.mp4

Profile of the file can be verified using ffmpeg

Workaround 1: Disable dynamic frequency change by programing DFS_ENABLE = 0:


Workaround 2: If switching frequency, program the register field values as follows:

if (old_freq/new_freq >= 7) {
    if (PBR_EN==1) {  // Per-bank refresh is enabled
          AREF_HIGH_THRESHOLD = 19
          AREF_NORM_THRESHOLD = 18

    else {  // Per-bank refresh is disabled
          AREF_HIGH_THRESHOLD = 18
          AREF_NORM_THRESHOLD = 17
          AREF_CMD_MAX_PER_TREF = 8
