Gstreamer issue in NX: Nano is faster than NX!

niki-maleki · December 16, 2020, 12:33am

Hi there,

I was using the following commands on NANO and it was working perfectly, then I switched to NX and run the exact same commands but surprisingly it works with lots of hiccups and short pauses in the video:
I am using
gstreamer (gst-launch-1.0) Version: 1.14.5,
Jetpack 4.4.1 (L4T 32.4.4)
CUDA:10.2.89
cuDNN: 8.0.0.180
TensorRT: 7.1.3.0

On both NX and NANO.

and I have tried with and without jetson_clocks on both boards with no difference in the performance. CPU and RAM are below 30% while running the commands.
My Test involves 4 scripts:

TCP SERVERS: which get the frames from usb3.0 camera and provides them on multiple tcpserversinks for different types of clients:

SCRIPT:
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2, width=1920, height=1080, framerate=60/1 ! tee name=t t. ! videorate max-rate=15 ! nvvidconv ! ‘video/x-raw(memory:NVMM),width=1920,height=1280’ ! omxh264enc bitrate=10000000 preset-level=2 ! ‘video/x-h264, stream-format=(string)byte-stream’ ! h264parse ! queue ! rtph264pay config-interval=1 pt=96 ! gdppay ! queue ! tcpserversink port=5002 sync=false async=false t. ! videorate max-rate=20 ! nvvidconv ! ‘video/x-raw(memory:NVMM),width=880,height=512’ ! omxh264enc bitrate=2000000 preset-level=2 ! ‘video/x-h264, stream-format=(string)byte-stream’ ! h264parse ! queue ! rtph264pay config-interval=1 pt=96 ! gdppay ! queue ! tcpserversink port=5001 sync=false async=false t. ! videorate max-rate=30 ! nvvidconv ! ‘video/x-raw(memory:NVMM),width=1920,height=1080’ ! omxh264enc bitrate=10000000 preset-level=2 ! ‘video/x-h264, stream-format=(string)byte-stream’ ! h264parse ! queue ! rtph264pay config-interval=1 pt=96 ! gdppay ! queue ! tcpserversink port=5000 sync=false async=false -e

TCP CLIENTS: Here I just want to refer to those ones which are problematic (slow) on NX (as mentioned earlier, they work perfectly fine on NANO)

2.1. Client 1: Gets data from TCPSERVER, makes modifications, and sends them udpsink.
Script:
gst-launch-1.0 tcpclientsrc port=5002 ! gdpdepay ! rtph264depay ! queue ! h264parse ! omxh264dec ! ‘video/x-raw(memory:NVMM),width=1920,height=1280’ ! nvvidconv ! ‘video/x-raw(memory:NVMM),width=1920,height=1280’ ! nvvidconv ! ‘video/x-raw,width=1280,height=720’ ! textoverlay text=“TITLE” shaded-background=yes deltay=-20 deltax=-20 valignment=top halignment=left font-desc="Sans, 10" ! nvvidconv ! ‘video/x-raw(memory:NVMM)’ ! omxh264enc bitrate=2000000 preset-level=0 ! ‘video/x-h264, stream-format=(string)byte-stream’ ! h264parse ! queue ! rtph264pay config-interval=1 pt=96 ! gdppay ! queue ! udpsink host=10.0.0.1 port=6000 buffer-size=100000000 sync=false async=false -e

NOTE1: In spite of those “CRITICAL” warnings, the pipeline works fine.
NOTE2: These errors happen both on NANO and NX.

Question1: Is it possible that this is actually causing some errors in the background that is contributing to the problem I described?
Question2: Why these warnings are happening? how can I modify my GStreamer pipeline to get rid of them?

Client 2.1.1 : (In remote windows OS) : gets data from udpsrc and displays it on the monitor.
Script:
gst-launch-1.0 udpsrc port=6000 ! gdpdepay ! rtph264depay ! avdec_h264 ! video/x-raw ! autovideosink sync=false async=false

Output:

Note: At this point I can see the video on the display (in remote windows OS) but with NANO, the video is much smoother than NX.

2.2. Client 2: Gets the data from TCPSERVER and saves it on the disk.
Script:
gst-launch-1.0 tcpclientsrc port=5000 ! gdpdepay ! rtph264depay ! queue ! h264parse ! mpegtsmux ! filesink location=/media/6FE3-EC2C/test.ts -e
Output:

Note: After Running This command, the file (test.ts) will be created on the disk and keeps recording the data. ( Again the recoded video in NANO is smoother)

2.3. Client3: Gets data from TCP Server, adds text overlays, then saves them on the disk.
SCRIPT:

gst-launch-1.0 tcpclientsrc port=5000 ! gdpdepay ! rtph264depay ! queue ! h264parse ! omxh264dec ! ‘video/x-raw(memory:NVMM),width=1920,height=1080’ ! nvvidconv ! ‘video/x-raw,width=1920,height=1080’ ! textoverlay text=“TITLE” valignment=top halignment=left font-desc=“Sans,15” ! textoverlay text=“TITLE2” valignment=bottom halignment=left deltay=-45 font-desc=“Sans,10” shaded-background=yes ! nvvidconv ! ‘video/x-raw(memory:NVMM)’ ! omxh264enc bitrate=10000000 preset-level=2 ! ‘video/x-h264,stream-format=(string)byte-stream’ ! h264parse ! mpegtsmux ! filesink location=/media/6FE3-EC2C/test_overlay.ts -e

NOTE1: I still get those “CRITICAL” warnings but again the pipeline works and creates the video files.
NOTE2: As you may have noticed, I am writing to a USB flash drive, which is USB3, but due to the bandwidth of the USB3 and the amount of inputs (from camera) and outputs (to files) I don’t think this would be an issue.
NOTE3: It is the exact same setup on NANO as well, but again NANO performs much better.

Question3: How can I get rid of these “CRITICAL” warnings?

ALL clients (except for the one that I mentioned which runs on windows) and the server script are running locally on NX (or NANO) at the same time.

I truly appreciate if someone can tell me what might be wrong or what I can do to get at least the same performance on NX if not better, plus, it would be great if you can answer questions 1-3 about the CRITICAL messages that I get after running the scripts.

Thank you!

Not sure, but you may try;

TCP servers

Adding queue in front of any subpipeline after tee in tcp server.
If your camera can provide lower framerate than 60 fps, try lowering and if it can do 15 fps try removing videorate.
Try mkv container rather rtph264 that relies on UDP packetization if you use gdp and TCP.

TCP clients:
If using RTP over UDP, you may remove gdp

DaneLLL · December 16, 2020, 2:21am

Hi,
Please execute sudo nvpmodel -m 2, sudo jetson_clocks and try again. All power modes are listed in
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fpower_management_jetson_xavier.html%23wwpID0E0NO0HA

You can execute sudo tegrastats to check CPU/GPU clocks.

niki-maleki · December 18, 2020, 9:52pm

Thank you DaneLLL for your response. I executed those commands, but the result is the same.

niki-maleki · December 18, 2020, 10:32pm

Thank you for your response.

I added queue in front of the sub-pipelines.
My camera unfortunately only has 60 FPS output.
I have not worked with mkv container, can you send me an example ?

DaneLLL · December 28, 2020, 6:17am

Hi,
Please use nvv4l2h264enc and set maxperf-enable=1

  maxperf-enable      : Enable or Disable Max Performance mode
                        flags: readable, writable, changeable only in NULL or READY state
                        Boolean. Default: false

This runs encoder in maximum clock. Should bring max encoder throughput.

niki-maleki · January 4, 2021, 8:14am

Dear DaneLLL,

Thank you for your suggestions. Here is what I did >>

So for the next tests, I set the power mode to 2 (15W 6Core) using sudo nvpmodel -m 2, and ran sudo jetson_clocks, then ran the following Gstream commands.

Test 1:
Running the scripts as is mentioned in my first post.

Could it be a hardware related or a driver-based issue?

DaneLLL · January 4, 2021, 9:31am

Hi,
The tegrastats shows encoder and decoder are at max frequencies, so it should not be an issue in hardware encoding/decoding. Please break down the pipeline with fpsdisplaysink text-overlay=0 video-sink=faksink -v. In breaking down the pieline and checking framerate, we should be able to know which plugin slows down the pipeline.

niki-maleki · January 12, 2021, 11:38pm

Hi,

So I applied fpsdisplaysink to the streaming pipeline (on test 3 with nvv4l2h264enc and nvv4l2decoder ). Strangely enough, it shows exactly 15 Avg FPS with 0 dropped frames (** on client 1 which is set to be 15 FPS**) . But still has those hiccups. I attached the video to show (with fpsdisplay text-overlay) what exactly I mean by hiccups.

DaneLLL · January 29, 2021, 7:19am

Hi,
Is it possible to check in a lighter environment? Some how it looks like the source is fixed at 15fps. The scene looks dark. Maybe the source reduces frame rate to get enough exposure time. We have seen that some USB cameras run in dynamic frame rate:

niki-maleki · February 15, 2021, 6:56am

Hi DaneLLL,

I performed different tests and I am confident it is not due to the USB camera dropping frames. Because if it was for the camera, then the video clip recorded by client 3 must have been affected as well but it is not. That video is recorded perfectly without any hiccups. I still have suspicion towards either driver or the hardware itself. Everything is identical with NANO but NX cannot perform the way Nano does!
Moving from omxh264 encoders and decoders to nvv4l2 decoders and encoders is the only thing that has affected my output in a tangible manner (as I described earlier in this thread) but it is still not ideal. Nano still outperforms NX which does not make any sense!
Is there any way I can help you or the support team to find what this issue is? I need to make a financial decision based on these results and I really wish we can figure out what is exactly wrong and how it can be fixed.
Thank you again for your help and patience.

DaneLLL · February 17, 2021, 6:49am

Hi,
Please share brand and model(such as E-Con CU135 ) of the USB camera.

And please check if you can achieve desired frame rate by running:

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2, width=1920, height=1080, framerate=60/1 ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

See if it can achieve 60fps in capturing frames.

kayccc · February 25, 2021, 5:42am

Hi niki-maleki,

Any update? Is this still an issue to support?

niki-maleki · February 25, 2021, 8:05pm

Hi @kayccc
Thank you so much for the follow-up and sorry for the late reply. Due to the issues we had recently, I was not able to run the tests. I will run the command and update the results by the next week.

niki-maleki · March 17, 2021, 8:11pm

Hi @DaneLLL

Sorry for the late reply.
The camera is Q10F made by Viewpro. Here is the link: http://www.viewprotech.com/index.php?ac=article&at=read&did=279

Also, I ran your script and it seems like my framerate is consistently near 60 FPS.
Here is the results of running the script:

Hi,
For pipeline optimization you can use nvv4l2camerasrc. It can capture frames into NVMM buffers to save one memory copy. By default it supports UYVY, you can download the source code, apply the patch, and rebuild/replace it.

And we have enabled DFS of VIC engine. For running 60fps, it might be better to run VIC at max clocks always. Please check
Nvvideoconvert issue, nvvideoconvert in DS4 is better than Ds5? - #3 by DaneLLL
