support for Jetson nano

[nirvitarka]

Does this support Nvidia Jetson Nano? I am not able to run it on jetson nano, having Jetpack 4.4 developer preview & deepstream 5.0 installed

Yes it runs on Jetson Nano. Can you describe the problem you’re having?

I do not have any camera with me currently, hence I changed the python-example from gtc-2020-demo code which I got from
here
https://github.com/RidgeRun/gtc-2020-demo

When I change the source of stream to anything else than camera, I get error.

Below is the code I am using

`client = GstdClient()
camera0 = PipelineEntity(client, 'camera0', 'videotestsrc pattern=snow ! video/x-raw,width=1280,height=720 ! interpipesink name=camera0 forward-events=true forward-eos=true sync=false')

pipelines_base.append(camera0)

camera0_rgba_nvmm = PipelineEntity(client, 'camera0_rgba_nvmm', 'interpipesrc listen-to=camera0 ! video/x-raw,format=YUY2,width=1280,height=720 ! videoconvert ! video/x-raw,format=NV12,width=1280,height=720 ! nvvideoconvert ! video/x-raw(memory:NVMM),format=RGBA,width=1280,height=720 ! queue ! interpipesink name=camera0_rgba_nvmm forward-events=true forward-eos=true sync=false caps=video/x-raw(memory:NVMM),format=RGBA,width=1280,height=720,pixel-aspect-ratio=1/1,interlace-mode=progressive,framerate=30/1')

pipelines_base.append(camera0_rgba_nvmm)

h264 = PipelineEntity(client, 'h264', 'interpipesrc name=h264_src format=time listen-to=camera0_rgba_nvmm ! video/x-raw(memory:NVMM),format=RGBA,width=1280,height=720 ! nvvideoconvert ! nvv4l2h264enc ! interpipesink name=h264_sink forward-events=true forward-eos=true sync=false async=false enable-last-sample=false drop=true')

pipelines_video_enc.append(h264)

for pipeline in pipelines_base:
pipeline.play()

time.sleep(10)

for pipeline in pipelines_video_enc:
pipeline.play()

time.sleep(20)`

creating a interpipesink is working fine. However, the interpipesrc, created in the encoding pipeline does not work.

I get below error :

0:00:33.451096787 22217 0x55b89729e0 ERROR gstdnoreader gstd_no_reader.c:77:gstd_no_reader_read:<GstdNoReader@0x7f7832b0c0> Unable to read from this resource

The problem is not in GstD. GTC 2020 demo works on TX2 only. It will fail for Nano.

We updated the GTC 2020 to work on Nano using a new branch: https://github.com/RidgeRun/gtc-2020-demo/tree/feature/support-jetson-nano

When I use jetson-nano-2GB version command line to enter gstd, it will show：
Gstd version 0.11.3
Copyright (C) 2015-2020 RidgeRun (https://www.ridgerun.com)

Process 27196 died: no such process; try to delete PID file. (/Usr/local/var/run/gstd//gstd.pid)
The log trace will be saved to /usr/local/var/log/gstd/gstd.log.
Separated from the parent process.

Google tells me the problem is the path //；
so I manually delete the/Usr/local/var/run/gstd/gstd.pid file, the first problem is gone, but the second problem still exists, it will display: Gstd version 0.11.3
Copyright (C) 2015-2020 RidgeRun (https://www.ridgerun.com)

Log traces will be saved to /usr/local/var/log/gstd/gstd.log.
Detaching from parent process.

Have you encountered the same problem? I'll appreciate if I can get the help！

[wanlong-peng]

when I start: DISPLAY=:0 gstd -D
and I start /home/hrg/gtc-2020-demo/python-example/media-server.py
it cause an ERROR like this:
Gstd version 0.11.3

I will appreciate it if who can give me some suggection!
