Low FPS problem with 4K encoding in Jetson Tx2

jkyun · September 16, 2020, 7:24am

HI All,

I am trying to stream 4K video with a Jetson TX2 board. This board will be adapted to a drone over 5G network. When I tested gstreamer pipeline on the Jetson TX2 developer board, there were no problem to play 4K 30 FPS and to stream 4K RTP 30 FPS. The picture has a good quality when I stream 4K video with bandwidth 10Mbps.

However, the Jetson TX2 carrier board, which was brought from a drone service provider, displays only 18-20 FPS no matter what method it takes. Also, the frame breaks a lot when transmitted over the network. The carrier board has one TC358840 chip. I also tested with Magewell USB Capture HDMI 4K Plus (It is USB3 type encoder).

The kernel version of Jetson TX2 developer board is lastest, but the Jetson TX2 carrier board has 28.2.1 kernel and a gstreamer version is 1.8.3. The best choice is to upgrade the kernel of the carrier board and install the corresponding chipset driver, but we can’t do it right away. I searched the related posts many times and tried them, but I couldn’t solve the problem. I want to know what should I do more before upgrading the kernel.

The carrier board :

My questions are;

In Jetson TX2 custom carrier board, 4K local display and 4K RTP streaming do not shows enough FPS(only 18~20).
Network performance is not good. RTP pictures do not show good quality.

What shoud I check??

Any help would be appreciated!

Thanks.

Hi,
Please check if you can reach 4Kp30 with psuedo source:

$ gst-launch-1.0 videotestsrc num-buffers=900 is-live=1 ! video/x-raw,width=320,height=240 ! nvvidconv ! 'video/x-raw(memory:NVMM),width=3840,height=2160' ! omxh264enc ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=false -v

We can achieve 4Kp30 on default board. Ideally you should observe the same. So the bottleneck may be in the source(v4l2src) or network bandwidth. Does your source support I420? Please check the supported formats via
v4l2-ctl --list-formats-ext.

This board support I420. Here is the pipeline for RTP streaming.

gst-launch-1.0 v4l2src -vvv device=/dev/video1 do-timestamp=true ! nvvidconv ! ‘video/x-raw(memory:NVMM), width=3840, height=2160, format=I420, framerate=30/1’ ! omxh264enc control-rate=2 bitrate=10000000 insert-sps-pps=true insert-aud=true ! ‘video/x-h264, stream-format=(string)byte-stream’ ! h264parse ! rtph264pay mtu=1316 ! udpsink host=x.x.x.x port=8554 async=false sync=false

Do you use J130 TX2 carrier board?
That uses TC358840, 4K HDMI chip, on the board.
If YES, the vendor will not update the driver any more, as the chip has EOL.

Thank you, MtHiker.

That is not J130 TX2 carrier board. The developer said they made the carrier board.

MtHiker · September 17, 2020, 7:53am

@jkyun,

Then you need to upgrade device driver by yourself.

Hi,
The source can output YUYV. Please execute sudo jetson_clocks and run the pipeline to check if framerate is 30fps:

$ gst-launch-1.0 v4l2src ! video/x-raw,format=YUY2,width=3840,height=2160,framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

jkyun · September 17, 2020, 9:26am

Thank you for your help, DaneLLL.

Here is the result. I’ve set the format to UYVY

gst-launch-1.0 v4l2src ! video/x-raw,format=UYVY,width=3840,height=2160,framerate=30/1 ! nvvidconv ! ‘video/x-raw(memory:NVMM),format=NV12’ ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

Today, I received the same new carrier board as the previous one. However, the test results were the same as before. The FPS did not exceed 20. The image was broken a lot when it was transmitted over the network.

I read “So the bottleneck may be in the source(v4l2src) or network bandwidth.”, so first carried out the following command:

sudo apt-get remove v4l-utils
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=I420,width=3840,height=2160,framerate=30/1 ! nvvidconv ! ‘video/x-raw(memory:NVMM),format=NV12’ ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

The FPS went up to 27. I don’t know why!!.

Network quality is still bad. I don’t know what settings to change for good results.

Hi,
It looks like the source cannot steadily output in 30fps. It gets worse after several trials. Not sure but this might be due to thermal impact.

In using gstreamer, there is a memory copy in

v4l2src ! video/x-raw ! nvvidconv ! video/x-raw(memory:NVMM) ! ...

This might be a bottlenck. We have a sample 12_camera_v4l2_cuda in jetson_multimedia_api. Suggest you try it and see if you can achieve 4Kp30.

If network bandwidth is a possible bottleneck, you may try lower bitrate like 4Mbps.

Thank you, DaneLLL.

I will try more.

Hello, DaneLLL.

I found the high usage of CPU when executing below pipeline. Is there any solution to distribute ??

DaneLLL · September 18, 2020, 10:28am

Hi,
The memory copy may trigger high CPU usage:

'video/x-raw, width=3840, height=2160, framerate=30/1, format=I420' ! nvvidconv ! 'video/x-raw(memory:NVMM), width=3840, height=2160, format=(string)NV12, framerate=(fraction)30/1'

On r28.2.1, we have 12_camera_v4l2_cuda to eliminate the memory copy. However, there is no better solution for gstreamer.

On r32.4.3, we have a new plugin nvv4l2camerasrc to eliminate the memory copy.

Honey_Patouceul · September 18, 2020, 11:49am

Not sure it helps, but if not yet tried, you may try option io-mode of v4l2src such as:

gst-launch-1.0 v4l2src device=/dev/video0 io-mode=2 ! ...
