Pixelation while running RTSP streams

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU)

DGPU

• DeepStream Version

5.1 and 6.2

• JetPack Version (valid for Jetson only)

N/A

• NVIDIA GPU Driver Version (valid for GPU only)

Nvidia driver 535

Issue : We’re seeing pixelation on rtsp streams, running 15 streams and whenever there is movement of objects, there’s pixelation. Any changes on gst / deepstream config that you can recommend please? The network load looks OK, and these are IP cameras

Thanks

Hi,

On the deepstream app you only have two options: increasing the bitrate or changing the profile for the encoder:

#1=h264 2=h265
codec=1
#encoder type 0=Hardware 1=Software
enc-type=0
#sw-preset=1 #for SW enc=(0)None (1)ultrafast (2)superfast (3)veryfast (4)faster
#(5)fast (6)medium (7)slow (8)slower (9)veryslow (10)placebo
sync=0
bitrate=4000000
#H264 Profile - 0=Baseline 2=Main 4=High
#H265 Profile - 0=Main 1=Main10
# set profile only for hw encoder, sw encoder selects profile based on sw-preset
profile=0

A slower profile will increase latency but improve image quality. The bitrate shouldn’t affect latency as long as you have enough bandwidth.

Are you working with RTSP input sources? Are there RTSP output sink in your pipeline?

The pixelation shows there is network packets loss. Please tell us your complete pipeline.

5

RTSP input sources only. Sink type is fake sink.

Can you help us identify the packet losses ? We pinged the IP’s but couldn’t see any packet loss

6

How could you see the pixelation with fakesink?

7

Sorry, I meant EGL sink

8

Are you using the DeepStream sample applications? If yes, which one?

If you are not using the DeepStream sample applications, please tell us your pipeline and configurations.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
