Hello this pipeline is working fine on my jetson nano:
gst-launch-1.0 -vvv v4l2src device=/dev/video0 ! 'image/jpeg, width=(int)1920, height=(int)1080, pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)60/1' ! jpegdec ! nvvidconv ! nvoverlaysink sync=False qos=True
However when I run the same pipeline inside a docker container that is built using:
docker build -t switch -f dockerfiles/Dockerfile.main .
where my Dockerfile.main is:
ARG BASE_IMAGE=nvcr.io/nvidia/l4t-base:r32.4.2
FROM ${BASE_IMAGE}
ENV DEBIAN_FRONTEND=noninteractive
# needed for accessing jetpack. This is for 4.4
COPY ./dockerfiles/nvidia-l4t-apt-source.list /etc/apt/sources.list.d/nvidia-l4t-apt-source.list
COPY ./dockerfiles/jetson-ota-public.asc /etc/apt/trusted.gpg.d/jetson-ota-public.asc

CMD ["/bin/bash", "./run.sh"]
and run:
docker run --name ${DOCKER_NAME} --privileged=True -it --rm ${DOCKER_NAME} bash
Then run the same gstreamer command as above, I get:
WARNING: erroneous pipeline: no element "nvvidconv"
And it doesn’t work. Any idea why this happens inside docker ?
