Hi, I am trying to use gstreamer via docker.
My purpose is that my container installs GStreamer and then, it runs a gstreamer pipeline such as displaying my webcam for example. I have writen this dockerfile: FROM ubuntu:20.10 RUN apt-get update && \ apt-get -y install sudo RUN useradd -m docker && echo "docker:docker" | chpasswd && adduser docker sudo CMD /bin/bash RUN sudo -s apt-get update RUN apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio -y ENTRYPOINT gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw,width=640,height=480,framerate=30/1' ! videoconvert ! ximagesink USER docker It builds, but once I run the image with flags (--net=host -e DISPLAY -v $HOME/.Xauthority:/root/.Xauthority ) it returns an error: ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Cannot identify device '/dev/video0'. I know that this is a problem of my dockerfile because this GStreamer pipeline works in local. Hence, I would like to know how to solve this. Thanks for your valuable time. Regards, Andrés. _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
You need to mount your video device, something like:

Another way to do this is using `--device /dev/video0`, which gives the container access to less of your host device than `--privileged`. On Thu, Dec 3, 2020, 03:40 Craig Carey <[hidden email]> wrote:

Mounting dev points into docker containers is a very good idea. I solve a lot of problems doing that. On Fri, Dec 4, 2020, 9:15 PM Tyler Compton <[hidden email]> wrote:
