Gstreamer pipelines for Jetson TX1
|
|
|
Introduction
On this page you are going to find a set of pipelines used on Jetson TX1, specifically used with the Jetson board. The wiki page tries to describe some of the multimedia features of the platform like the NVIDIA model to handle the ISP through its custom (and close) plugin called nvcamerasrc. It also includes a brief description of the sample application called nvgstcapture-1.0 and ways to measure the ARM load when encoding/decoding using NVENC, NVDEC, NVJPG, etc. The goal is to provide you some example pipelines and introduction to the board. It is work in progress.
The camera sensor used for tests is the ov5693. These steps were run on Jetson TX1.
Jetson TX1 GStreamer pipelines
Recall that this board is a quad core A57 with some hardware units dedicated to encode/decode. Plugins accelerated by Hardware available:

Measure ARM load
There is a tool to measure the ARM load created by NVIDIA for the Jetson TX1. This tool seems to give better statistics of the ARM cores than top. In the remaining sections of this wiki the ARM load reported by top is included for reference to the reader but tegrastats should contain the real load.
Run it with sudo to get more information.

Jetson TX1 ARM load
This table tries to summarize the ARM load of different uses cases of the Jetson TX1 using gstreamer and the capture plugin. The second column has the ARM load of the pipeline measured in one instant, using that value and the known value for the capture process the third column estimates the load of the encoding or display process (subtract the capture load). The load represent a global load of the system (4 ARMs) just to give an idea to the reader of the system capabilities.
Feature | Pipeline load (%) | Feature load (%) |
---|---|---|
Capture | 11.25 | 11.25 |
Capture-Display | 18 | 6.75 |
H264 Encoding | 20 | 8.75 |
VP8 Encoding | 19.25 | 8 |
H265 Encoding | 13.75 | 2.75 |

NVMM memory
In order to get the best performance from the gstreamer elements that use the HW accelerators they have to receive something called NVMM memory, which we could imagine is contiguous and aligned memory ('nvbuffer', 'nv_buffer', 'nvmm'). At this point it is not clear what that memory is.
https://devtalk.nvidia.com/default/topic/903438/jetson-tx1/hw-accelerated-jpeg-encoding-/?offset=13#4839080 https://devtalk.nvidia.com/default/topic/901337/post/4747186/#4747186
There is a plugin to convert video/x-raw to video/x-raw(memory:NVMM)

VLC on Jetson TX1/TX2
In order to test some of the videos or incoming streams produced by the pipelines below you might need VLC installed in your Jetson module, there is a known issue with VLC version 2.2 and you need to download and install VLC 2.4 or newer, in order to do it please follow these steps:
sudo apt-get build-dep vlc && sudo apt-get install libtool build-essential wget http://download.videolan.org/pub/videolan/vlc/2.2.6/vlc-2.2.6.tar.xz tar -xf vlc-2.2.6.tar.xz cd vlc-2.2.6 ./configure --disable-qt make #you can also try: make install
It takes around 10min to build. Once you have built the new vlc, you can run this to open a plain UDP stream for instance
./vlc -vv --demux h264 --h264-fps 60 udp://@:5000
this issue has been reported on NVIDIA's forum
Capture
In order to capture there are two ways: Using v4l2 or using nvcamerasrc.
nvcamerasrc
This plugin was created by nvidia and it has access to the ISP that helps converting from bayer to yuv suitable for the video encoders. However, it seems that its usage is limited to the ov5693 sensor until NVIDIA releases its source code or until it adds support to v4l2 to use the ISP.
gst-launch-1.0 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' ! fakesink silent=false -v
When the pipeline is launched a daemon appears on top nvcamera-daemon, one question about the daemon was posted on the Nvidia Embedded Computing Forum
ARM consumption: 45% of one core (4 cores available 400% - this means something like 11.25% of total)

The nvvidconv is required normally to convert the memory type, however, on this case it is used to flip the image. Removing the flip from the pipeline saves like 5% of ARM load.

v4l2src
Starting on L4T R23.2 there is a /dev/video0 node to capture, however, this node will give you frames in bayer which are NOT suitable to encode because it grabs frames directly from the ov5693 camera without using the ISP.

It works also with the UVC driver. David suggested the creation of a nvisp element to convert bayer to yuv
Capture and Display
nvcamerasrc
gst-launch-1.0 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' ! nvoverlaysink -e
ARM consumption: 72% of one core (4 cores available 400% - this means something like 18% of total). However, only the capture is 11.25% so the display consumes 6.75%. For other camera you can find in our wiki latency numbers for glass to glass measurements

H264 encoding
videotestsrc
ARM load: 175% 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 !

Codecvisa reports bitrate on 7.96Mbps when variable mode is selected on the encoder.
ARM consumption ~80% of one core (4 cores available 400% - this means something like 20% of total). However, only the capture is 11.25% so the h264 consumes 8.75%

H265 UDP Streaming
In order to start streaming H265 you need the h265 payloader, to do this you need to compile the latest version of gstreamer in your Jetson TX1. Please follow the instructions to do it. Same instructions can be run in your PC if you want to update the gstreamer version in your host. (in case of the host I had to recompile the good plugins to get the rtph265pay).
Currently it is not possible to receive the stream using the PC because there is not a h265 decoder available on gstreamer. In order to evaluate the performance let's receive the stream on the Jetson module as well.

nvgstcapture-1.0
This is an application based on gstreamer and omx to capture, encode and save video to the filesystem. It has a lot of options. The source code is not released by NVIDIA yet but they are planning to release in future versions of Linx 4 Tegra (L4T), you can read about it at Nvidia Embedded Computing Forum

Capture snapshots
Sometimes when the board has been just flashed you need to run reboot in order to run nvgstcapture-1.0 successfully. To take snapshots:
nvgstcapture-1.0 #then press j to take an snapshot q
Resolutions available to create snapshot:
(2) : 640x480 (3) : 1280x720 (4) : 1920x1080 (5) : 2104x1560 (6) : 2592x1944 (7) : 2616x1472 (8) : 3840x2160 (9) : 3896x2192 (10): 4208x3120
nvgstcapture-1.0 -m 1 --image-res=10
In general the application is consuming 70% of one core. It is always displaying video this could affect.
Capture and record video
nvgstcapture-1.0 -m 2 # set the mode in video 1 # start video recording 2 # take a snapshot 0 # stop video recording
In case of video it should support:
(2) : 640x480 (3) : 1280x720 (4) : 1920x1080 (5) : 2104x1560 (6) : 2592x1944 (7) : 2616x1472 (8) : 3840x2160 (9) : 3896x2192
However, it is not possible to set other value than 2,3,4,5 up to 9.
nvgstcapture-1.0 -m 2 --video-res=5

There is a daemon and a pipeline. Interesting...
While recording the pipeline (nvgstcapture) increases the ARM load to 10% and then it goes down again, even with the highest resolution. It will be interesting to understand what is the daemon doing.
