gst-launch-1.0 preview is just a black video - no error messages

Question

gst-launch-1.0 preview is just a black video - no error messages

Opened this issue 4 months ago · 6 comments

I am unable to use my camera inside the docker container. Testing with gst-launch-1.0 v4l2src ! videoconvert ! autovideosinki get a preview window with just a black screen.
The same command runs just fine outside the container. So I know the camera works with v4l2src.

To start the container I run

$ docker/run.sh

Addendum

My actual purpose with this issue is to fix roslaunch ros_deep_learning video_viewer.ros1.launch, but I figured it might be related, and gst-launch-1.0 is easier to test with.

Answer 1 · 2024-07-15T13:58:54.000Z

Another test, maybe it is relevant.
test-video.py fails with the same timeout message.

/jetson-inference/build/aarch64/bin# python3 test-video.py

I want to hightlight from the below output:

@andanders are you able to see the video stream with nvgstcapture-1.0 tool? Normally I try this first with MIPI CSI camera. This model has some custom formats in YUYV/NV16 format that I have not tried before. Also with video-viewer you want to use csi://0 for MIPI CSI camera (nvarguscamerasrc in GStreamer pipeline or if using gst-launch), not V4L2 /dev/video0 - the V4L2 driver does not use ISP.

Answer 3 · 2024-07-17T09:35:03.000Z

For the sake of clarity; the camera and computer combo that I'm using is e-con sturdecam 20, and Syslogic RS A4NA. They are connected with GMSL and a built-in deserializer. So I don't know if it is strictly MIPI or CSI.

system detects the camera as ...

~$ sudo v4l2-ctl --list-devices
NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca):
	/dev/media0

vi-output, ar0230 30-0043 (platform:tegra-capture-vi:1):
	/dev/video0

Anyhow.

nvgstcapture-1.0
Directly on host machine

The following command opens a black window (no video), and a "no cameras available"

To my surprise nvgstcapture-1.0 is not included in the container - I'm trying to install it according to theseinstructions) but without success so far.

video-viewer
Results for running ./video-viewer with csi://0 is a bit different. I get a "No cameras available" error, followed by the same "a timeout occurred"

I almost forgot to test with nvarguscamerasrc

@andanders if nvarguscamerasrc and nvgstcapture aren't working, then I would consult with your camera manufacturer to make sure you have the right drivers or version of JetPack installed to support it.

If I modify docker/run.sh by adding --privileged,
I can run /build/aarch64/bin/video-viewer /dev/video0 and get a preview inside the container.

E-con systems have responded:

Our Camera STURDeCAM20 has an on-board ISP and does not use NVIDIA ISP. The cameras which use NVIDIA ISP can only use nvgstcapture and nvarguscamerasrc.

Though our cameras does not use NVIDIA ISP, it can be streamed through NVIDIA ISP by using nvv4l2camerasrc.
To stream STURDeCAM20 via NVIDIA ISP use the below command:

$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video<video node> ! 'video/x-raw(memory:NVMM), format=(string)UYVY, width=(int)<width>, height=(int)<height>' ! nvvidconv ! 'video/x-raw(memory:NVMM), format=(string)I420, width=(int)<width>, height=(int)<height>' ! nv3dsink sync=false -v

I'm not sure what I'm supposed to do with that information.
If running the container as privileged works, then thats my lot.

But this just gives me other problems down the road, because the ros_deep_learning examples fail.
