videotestsrc

ARM load: 157% but only videotestsrc consumes 100%. According to the NVIDIA forum when using videotestsrc the system is also doing memory copies to feed the encoder with NVMM memory buffers so that loads more the ARM. 

gst-launch-1.0 videotestsrc num-buffers=150 ! 'video/x-raw, format=(string)I420,width=(int)640, height=(int)480' ! omxh264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! filesink location=test.h264 -e

VLC can play the file correctly at 30fps and reports as codec: H264-MPEG-4 AVC (part 10) (h264). The fan on top of the SoC didn't turn on.

nvcamerasrc

gst-launch-1.0 -e nvcamerasrc fpsRange="30.0 30.0" ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1' ! \
nvvidconv flip-method=2 ! 'video/x-raw(memory:NVMM), format=(string)I420' ! omxh264enc bitrate=8000000 \
! 'video/x-h264, stream-format=(string)byte-stream' ! filesink location=test.h264 -e

Codecvisa reports bitrate on 7.96Mbps when variable mode is selected on the encoder.

ARM consumption 45.4% of one core (4 cores available 400% - this means something like 16.75% of total). However, only the capture is 11.25% so the h264 consumes 5.5%

H.265

VLC with H265 support

In order to support h265 you need VLC 2.2 in your computer to play the videos 

sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install vlc vlc-plugin-*

videotestsrc

ARM load: 156% but only videotestsrc consumes 100%. According to the NVIDIA forum when using videotestsrc the system is also doing memory copies to feed the encoder with NVMM memory buffers so that loads more the ARM. 

gst-launch-1.0 videotestsrc num-buffers=150 ! 'video/x-raw, format=(string)I420,width=(int)640, height=(int)480' ! omxh265enc ! filesink location=test.h265 -e

VLC can play the file correctly at 30fps and reports as codec: MPEG-H Part2/HEVC (H.265)(hevc). The fan on top of the SoC didn't turn on.

nvcamerasrc

gst-launch-1.0 -e nvcamerasrc fpsRange="30.0 30.0" ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1' ! \
nvvidconv flip-method=2 ! 'video/x-raw(memory:NVMM), format=(string)I420' ! omxh265enc ! filesink location=test.h265 -e

Codecvisa reports bitrate on 7.96Mbps when variable mode is selected on the encoder.

ARM consumption ~55% of one core (4 cores available 400% - this means something like 13% of total). However, only the capture is 11.25% so the h264 consumes 1.75%
