I am trying to set up gscam on my Jetson TX2 with Jetpack 4.2.2 under Ubuntu 18.04. Streaming with gstreamer works perfectly well, but with gscam I receive no image feed. No errors are issued. I do have gscam installed in the following way:

sudo apt-get install -y libgstreamer1.0-dev gstreamer1.0-tools libgstreamer-plugins-base1.0-dev libgstreamer-plugins-good1.0-dev libyaml-cpp-dev
sudo apt-get install -y ros-melodic-camera-info-manager ros-melodic-camera-calibration-parsers ros-melodic-image-transport
sudo apt-get install -y ros-melodic-gscam

Running the following pipeline with gstreamer works well: gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=3840, height=1080 ! videocrop top=0 left=0 right=1920 bottom=0 ! tee name=t ! queue ! videoconvert ! omxh264enc ! video/x-h264, stream-format=byte-stream ! h264parse ! rtph264pay config-interval=1 ! udpsink host=10.0.1.111 port=5600 t. ! queue ! videoconvert However when I try the same with gscam no image is published and the process hangs (control C doesent work, I need to kill it)

export GSCAM_CONFIG="v4l2src device=/dev/video0 ! video/x-raw, width=3840, height=1080 ! videocrop top=0 left=0 right=1920 bottom=0 ! tee name=t ! queue ! videoconvert ! omxh264enc ! video/x-h264, stream-format=byte-stream ! h264parse ! rtph264pay config-interval=1 ! udpsink host=10.0.1.111 port=5600 t. ! queue ! videoconvert"
rosrun gscam gscam

I traced the messages with GST_DEBUG=4, no errors are occuring, here is the tail of the log:

Did you ever get this resolved?

nope. I finally skipped gscam and I am using now a ROS image topic to RTSP streaming service which works amazingly well: https://github.com/CircusMonkey/ros_rtsp

Exchizz commented 4 years ago

I was kinda experiencing the same issue. I was getting one image published, and then nothing. One day of debugging later and it turns out I need this PR to make it work...

https://github.com/ros-drivers/gscam/pull/61

(It's a real shame nobody maintains this project)

GSCAM2 has a very active maintainer, ended up just switching to ROS2

aemarkov commented 3 years ago

I've just faced with the similar problem that gscam publish nothing. I investigated it a bit and look likes that gscam doesn't support dynamically created pads. gscam parses the part of the pipeline passed as environment variable:

pipeline_ = gst_parse_launch(gsconfig_.c_str(), &error);

and if some pads are dynamic, it couldn't be lined, but gscam continue working, but nothing is published.

In my case the problem was in the decodebin. Maybe it will helpful for you.
