50 CCTV cameras video analysis

sivaishere96 · December 6, 2019, 11:28am

I want to run SSD-Mobilenetv2 on AGX Xavier for 50 cctv live camera streams each running at a minimum 15fps. Is it possible?

Looking at the mlperf 0.5 multistream results, it states that the AGX Xavier can run 102 streams.

https://blogs.nvidia.com/blog/2019/11/06/ai-inference-mlperf-benchmarks/.

Running source source30_1080p_dec_infer-resnet_tiled_display_int8.txt, I was able to get only 30 sources. Increasing the number of sources beyond 30 results in decrease in fps.

Hi sivaishere96,

I will suggest to use DeepStream SDK, please refer to https://developer.nvidia.com/deepstream-sdk

As i have mentioned above, I am using the source30_1080p_dec_infer-resnet_tiled_display_int8.txt config file which is a part of deepstream. I am facing this problem while using deepstream. Without deepstream I am getting much worse results.

Hi,
You may try in running Xavier in max performance. Please refer to
https://devtalk.nvidia.com/default/topic/1049168/

source30_1080p_dec_infer-resnet_tiled_display_int8.txt is what we have verified. Your usecase is more aggressive. Please give it a try.

sivaishere96 · December 10, 2019, 2:48am

I am running the device in maximum performance mode.

In the mlperf results, it stated that the age Xavier can process almost 2500 images in offline mode and 102 batches in multi-stream mode for ssd mobilenet v2. Shouldn’t the multi stream results mean that the Xavier can process 102 streams running ssd mobilenet v2 at 20 FPS.

Hence I thought running 40 streams shouldn’t be an issue.

Hi,
By default source30_1080p_dec_infer-resnet_tiled_display_int8.txt runs ResNet. Do you also hit performance bottleneck in running ResNet? Would like to know if it is specific to mobilenetv2.

sivaishere96 · December 10, 2019, 6:47am

Yes. The issue was with both Resnet and mobilenetv2.

Hi,
Please share your config file for reference. You may put it in

or zip and attach it/

Also please run tegrastats to check if GPU runs at max clocks and reaches 100% loading.

sivaishere96 · December 12, 2019, 4:35am

source30_1080p_dec_infer-resnet_tiled_display_int8.txt is the config file that we have used. Everything is the same except that the number of sources have been changed to 50.

Will update you with the log in a while as I am travelling right now.

sivaishere96 · December 18, 2019, 5:19am

Hi DaneLLL,

I have an update. I am trying to run only 30 sources. However the performace does not seem to be consistent. During one run all the sources seem to run at 30 fps without any problem.

And this seems to happen randomly for different runs. There is no pattern.I am monitoring the temperatures and the utilization; they seem to be fine and within limits. I even tried running the code for 4 hours straight and it ran without any problems with all the sources running at a stable 30 fps.

FYI: I have set the interval parameter to be 2 here in the experiments.

And the performace is starking to me because it is claimed by nvidia that the AGX Xavier can process around 2500 images/sec for ssd-mobilenetv2 and it is not even remotely close to the number I am getting here. Although I am running detectnetv2-Resnet-10 I should expect atleast half the number of images/sec.

Hi,
Please run ‘sudo nvpmodel -m 0’ to be in MAXN mode:
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fpower_management_jetson_xavier.html%23wwpID0E0AO0HA
And ‘sudo jetson_clocks’ to enable max performance.

In config file, you can set ‘type=5’ to use nvoverlaysink and ‘syc=0’ in [sink0].
https://docs.nvidia.com/metropolis/deepstream/dev-guide/index.html#page/DeepStream_Development_Guide%2Fdeepstream_app_config.3.2.html%23wwpID0ENHA

Also can try to set ‘live-source=1’ in [streammux]
https://docs.nvidia.com/metropolis/deepstream/dev-guide/index.html#page/DeepStream_Development_Guide%2Fdeepstream_app_config.3.2.html%23wwpID0E0DB0HA

You can use tegrastats to check if GPU is at max clocks and 100% loading.
