Streaming a rosimagesrc #60

Closed YairMobile19 closed 6 months ago

Hello, and thanks for your help in this wonderful project! I'm trying to stream a ros image by using the following pipeline ( NVidia jetson ):

gst-launch-1.0 rosimagesrc ros-topic=/testimage ! queue ! nvvidconv ! 'video/x-raw(memory:NVMM), format=NV12' ! nvv4l2h264enc bitrate=8000000 ! 'video/x-h264, stream-format=by te-stream' ! h264parse ! rtph264pay config-interval=1 pt=96 ! udpsink host=211.222.1.1 port=5006 auto-multicast=true

And I am getting the following error:

No protocol specified No EGL Display nvbufsurftransform: Could not get EGL display connection Setting pipeline to PAUSED ... Opening in BLOCKING MODE Pipeline is live and does not need PREROLL ... [INFO] [1704115424.792004415] [gst_image_src_node]: getcaps with filter 'NULL' [INFO] [1704115424.792173825] [gst_image_src_node]: waiting for first message Setting pipeline to PLAYING ...

The same pipeline works fine for a videotestsrc. Can anyone help me with this?

Thanks

Okay, I think I got it. nvv4l2h264enc doesn't support the source format.
