Docker libv4l2: error getting capabilities

• Hardware Platform (Jetson / GPU)

  • Ubuntu 18.04

  • Jetpack 4.6.1 R32.7.1

    cat /etc/nv_tegra_release
    R32 (release), REVISION: 7.1, GCID: 29818004, BOARD: t186ref, EABI: aarch64, DATE: Sat Feb 19 17:07:00 UTC 202
    

• Issue Type: bug

  Running a GStreamer decoding pipeline fails in docker but succeeds on the host.

  The following GStreamer pipeline, decodes a h264 stream and saves it to the local file system.

  On the host it seems to work flawless

  $ gst-launch-1.0 videotestsrc num-buffers=100 ! 'video/x-raw, format=UYVY, width=1920, height=1080, framerate=60/1' ! nvvidconv ! 'video/x-raw(memory:NVMM), format=NV12' ! nvv4l2h264enc !

  When we try to run the same pipeline in the l4t-base container the library files aren’t loaded properly. The pipeline fails and reports it isn’t able query the decoding device capabilities.

  docker run --rm --network=host --runtime=nvidia --privileged  nvcr.io/nvidia/l4t-base:r32.7.1  gst-launch-1.0 videotestsrc num-buffers=100 !

  When we run the same command with a sleep 1 && it does seem to work properly, why does this approach solve the previous issue? We would like to avoid running the container in this way, is this a possibility?

  docker run --rm --network=host --runtime=nvidia --privileged  nvcr.io/nvidia/l4t-base:r32.7.1 sleep 1 &&   gst-launch-1.0 videotestsrc num-buffers=100 !

Noticed a very similar issue. Any updates?

[Amycao]

The second command, the last part gst command actually run on your host, not within container.
docker run --rm --network=host --runtime=nvidia --privileged nvcr.io/nvidia/l4t-base:r32.7.1 sleep 1 && gst-launch-1.0 videotestsrc num-buffers=100 ! ‘video/x-raw, format=UYVY, width=1920, height=1080, framerate=60/1’ ! nvvidconv ! ‘video/x-raw(memory:NVMM), format=NV12’ ! nvv4l2h264enc ! ‘video/x-h264, stream-format=(string)byte-stream’ ! h264parse ! nvv4l2decoder ! filesink location=/tmp/h264.test

[Amycao]

Please use docker container based on compatible JP version and DS version.

Hi @Amycao , Running the pipeline with the deepstream-l4t:6.0.1-base image results in the same issue.

Can you find the library libnvinfer.so.8, libnvparsers.so.8, libcufft.so.10 within container?

[simon_dg]

@Amycao
The library files are not available within the container

nvidia-docker run --network=host -it --runtime=nvidia nvcr.io/nvidia/deepstream-l4t:6.0.1-base /bin/bash

/opt/nvidia/deepstream/deepstream-6.0# find / -name libnvinfer.so.8

/opt/nvidia/deepstream/deepstream-6.0# find / -name libnvparsers.so.8

/opt/nvidia/deepstream/deepstream-6.0# find / -name libcufft.so.10

On the host I do find the files, stored on the following paths:

/usr/local/cuda-10.2/targets/aarch64-linux/lib/libcufft.so.10

/usr/lib/aarch64-linux-gnu/libnvparsers.so.8

/usr/lib/aarch64-linux-gnu/libnvinfer.so.8

[Amycao]

How about this?
docker run --network=host -it --runtime=nvidia nvcr.io/nvidia/deepstream-l4t:6.0.1-base /bin/bash

[ward.van.driessche]

Cannot find those files either:

$ docker run --network=host -it --runtime=nvidia nvcr.io/nvidia/deepstream-l4t:6.0.1-base /bin/bash
/opt/nvidia/deepstream/deepstream-6.0# find / -name libnvinfer.so.8
/opt/nvidia/deepstream/deepstream-6.0# find / -name libnvparsers.so.8
/opt/nvidia/deepstream/deepstream-6.0# find / -name libcufft.so.10

[simon_dg]

Any updates?

[Amycao]

How about your docker version?
dpkg -l|grep docker

This comes with JP 4.6.1. please run nvidia-docker run --rm -it IMAGE ID, if not work, please try to reinstall it to see if works.

Hi Amycao. Could you please provide instructions on how to reinstall nvidia-docker instead of listing your downloads?

[ward.van.driessche]

I have downloaded

• https://repo.download.nvidia.com/jetson/common/pool/main/n/nvidia-container-toolkit/nvidia-container-toolkit_1.7.0-1_arm64.deb

• https://repo.download.nvidia.com/jetson/common/pool/main/n/nvidia-docker2/nvidia-docker2_2.8.0-1_all.deb

And installed both with sudo dpkg -i <.deb> and now everything seems to work but I don’t understand how. Could you read through the steps below?

In short: we seem to have fixed it (thanks!) but we don’t know exactly how we fixed it, making it hard to prevent this from happening further in the future. Could you check what could have possibly gone wrong in the original setup?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

i am not sure what could gone wrong in your original setup. but suggest you flash with whole JP version next time, it will not have this version issue.
