We are using the Nvidia hardware h264 video encoding engine on Jetson TK1 , using firmware R21.4.
For our application, we have to set the H264 encoding profile to High (High 4:2:2) because we grab CSI input frames having a UYVY pixel format (Name: YUV422 (UYVY) packed ).
We did some tests with gstreamer-1.0 (ref http://developer.download.nvidia.com/embedded/L4T/r21_Release_v4.0/L4T_Jetson_TK1_Multimedia_User_Guide.pdf) and we are not able to set the h264 encoding profile(libnvomx always return OMX_IndexParamVideoProfileLevelCurrent not implemented).
Some research bring us to this topic https://devtalk.nvidia.com/default/topic/854385/-zjuislab-several-questions-about-video-encoding-on-tegra-k1/ describing the same issue.
On nvidia dev forum, it seems that an update of the libnvomx.so can solve it, and you already provided it.
Can we please get a newer version of the libnvomx.so for Tegra K1 that support H264 high profile encoding ?
Here is the dump of the file /etc/nv_tegra_release containing the SHA1 of the libnvomx.so
