3 weeks ago Found it — it comes along with nvv4l2 that gets installed in the x86 docker image. Here’s the key part:
# Install nvv4l2 for GXF Multimedia h264 codec
RUN --mount=type=cache,target=/var/cache/apt \
apt-get update && apt-get install -y \
nvv4l2 \
&& ln -s /usr/lib/x86_64-linux-gnu/libnvcuvid.so.1 /usr/lib/x86_64-linux-gnu/libnvcuvid.so \
&& ln -s /usr/lib/x86_64-linux-gnu/libnvidia-encode.so.1 /usr/lib/x86_64-linux-gnu/libnvidia-encode.so
I'm running a version of this on X86 with an NGC TensorRT image, but it's unable to find the libnvbufsurface.so library. I know this gets mounted on the Orin devices through the container toolkit, and it's primarily used for the Jetson multimedia API, but how is it leveraged on x86? I would assume the decoder / encoder would be NVDEC / NVENC based.
