• ffmpeg failed - 455 Method Not Valid in This State

  3 juin, par paty.r15

  I created a Node.js app that gets an RTSP stream with FFmpeg to analyse it with OpenCV 3. It is working if I install FFmpeg and OpenCV in my local.

  


  But now I created a Docker image that contains the installation of those libraries and I'm using it as a base to create another image & container where I'm trying to run my app. When I run it inside that container I get this error over and over again when trying to get the RTSP stream with an FFmpeg instruction for

  


  


  method SETUP failed : 455 Method Not Valid in This State

  


  


  This is how I am installing FFmpeg in the image :

  


  # ---------------------- OpenCV ffmpeg ---------------------------#
RUN mkdir -p /opt/src \
 && curl -Lo /opt/src/ffmpeg-${FFMPEG_VERSION}.tar.gz \
    http://ffmpeg.org/releases/ffmpeg-${FFMPEG_VERSION}.tar.bz2 \

  && cmake -D CMAKE_BUILD_TYPE=RELEASE \

    -D WITH_FFMPEG=ON .. \
  && make -j "$(nproc)" \
  && make install \
  && ldconfig -v \
  && rm -rf /opt/src


  


  Do you have any idea what this error is and how to fix it ? I think it might have to do with the initial configuration on the installation of either of them (FFmpeg or OpenCV).
