The hardware encoding using a jetson NX (nvv4l2h265enc )

david.strubel · July 30, 2020, 10:43am

Hello everyone , have a good new (or not).

I m trying to use the hardware encoding using a jetson NX enforgetly that doest work properly.
I acutaly working with IDS UEyes camera and using a GST-plugin to can load the cameras (link to the gst-plugin git https://github.com/joshdoe/gst-plugins-vision)

For exemple in my case this pipelines works :
GST_DEBUG=2 gst-launch-1.0 idsueyesrc config-file= /home/jetsonnx/UI327xLE-C_conf.ini ! videoconvert ! omxh265enc ! h265parse ! avdec_h265 ! videoconvert ! ximagesink
or ( for H264)
GST_DEBUG=2 gst-launch-1.0 idsueyesrc config-file= /home/jetsonnx/UI327xLE-C_conf.ini ! videoconvert ! x264enc bframes=0 key-int-max=45 bitrate=512 ! h264parse ! avdec_h264 ! videoconvert ! ximagesink

But i want to use the wonderfull power computaion of the jetson NX with the accelerat hardware encoding
Consequently i try to use nvv4l2h265enc with this pipelines:

GST_DEBUG=2 gst-launch-1.0 idsueyesrc config-file= /home/jetsonnx/UI327xLE-C_conf.ini ! videoconvert ! "video/x-raw" ! nvvidconv ! "video/x-raw(memory:NVMM)" ! nvv4l2h265enc ! h265parse ! avdec_h265 ! videoconvert ! ximagesink

This pipelines execute but show an black static screen and some warning appear in the terminal :

GST_DEBUG=2 gst-launch-1.0 idsueyesrc config-file= /home/jetsonnx/UI327xLE-C_conf.ini ! videoconvert ! “video/x-raw” ! nvvidconv ! “video/x-raw(memory:NVMM)” ! nvv4l2h265enc ! h265parse ! avdec_h265 ! videoconvert ! ximagesink

If you have any idea how to correct this error. My final target is to use the pipeline for creat an RTSP server (like that i not much focus on the pipeline after the H265pars to snik).

Thanks for your help.

Hi

I ran the below pipeline on JetPack 4.3 and it works properly.

gst-launch-1.0 videotestsrc ! nvvidconv ! nvv4l2h265enc ! h265parse ! avdec_h265 ! fpsdisplaysink async=false

You can reduce the pipeline by removing the software video converters and let pipeline negotiate independently.

Best Regards
Angel

Thanks a lote for your answer.
I test the Pipeline and infact is work well until i try to catch the camera stream( whish requiere the use of the idsueyesrc ) . I also use the jetsonPack 4.3

In my point of vieux the problem is propably due to the failed to probe pixel apect ratio with vidioc_cropcap . Do you have an idea to fix it.

Hi,

Could you run below pipeline and send output back?

gst-launch-1.0 idsueyesrc config-file= /home/jetsonnx/UI327xLE-C_conf.ini ! nvvidconv ! nvv4l2h265enc ! h265parse ! avdec_h265 ! fpsdisplaysink async=false -v --gst-debug=3

Thanks

david.strubel · August 5, 2020, 9:25am

Thanks a lot for your anwser and your help @aphillipso .
I try the pipeline you give. Unforgetly it doesn’t work and faill due to the unknown ‘async’ (see the debug message below)

I try to make it work without “async” parameters and similar error appears in the debug message ( Failed to probe pixel aspect ratio with VIDIOC_CROPCAP: Unknown error -1)

In my point of view the main problem is comming from the idsueyesrc to the encoder, somthing goes wrong with the conversion but no idea of what.

Hi

Seems the source element is not being able to handle properly the negotiated capabilities with the NVIDIA encoder. Maybe you can filter the capabilities between source and encoder

Run your pipeline adding -v

GST_DEBUG=2 gst-launch-1.0 idsueyesrc config-file= /home/jetsonnx/UI327xLE-C_conf.ini ! nvvidconv ! nvv4l2h265enc ! h265parse ! avdec_h265 ! fpsdisplaysink -v

To see if you can skip the capabilities that are failing

Thanks

Hi aphillipso
I m very happy you assit me on this tricky issue.

I try your pipeline but i get a classical error message ( relatively close than the privously optained)
I make some modification and finaly get some output (balck screen but still something :) )
The average FPS is around less than 5fps.
If you have Idea why i have a black screen (and i check it wasn’t because i leave the cap on camera :) )

For more detaill if that can be usefull let see the out put terminal.
