  • 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 \
  && tar -xvf /opt/src/ffmpeg-${FFMPEG_VERSION}.tar.gz -C /opt/src \
  && cd /opt/src/ffmpeg-${FFMPEG_VERSION} \
  && ./configure --enable-gpl --enable-avresample --enable-libopencore-amrnb \
  --enable-libx264 --enable-libxvid --enable-postproc --enable-version3 \
  --enable-shared --enable-pic --extra-ldexeflags=-pie \
  && make -j $(nproc) \
  && make install \
  && ldconfig -v \
  && rm -rf /opt/src

# ---------------------- OpenCV stuff ---------------------------#
RUN mkdir -p /opt/src/opencv-${OPENCV_VERSION}/build \
  && curl -sLo /opt/src/opencv3.tar.gz \
     https://github.com/Itseez/opencv/archive/${OPENCV_VERSION}.tar.gz \
  && tar -xzvf /opt/src/opencv3.tar.gz -C /opt/src \
  && cd /opt/src/opencv-${OPENCV_VERSION}/build \
  && cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D WITH_TBB=ON \
    -D WITH_OPENMP=ON \
    -D WITH_FFMPEG=ON .. \
  && make -j "$(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).

  • Screen Recording Issues using Python and FFMPEG [closed]

    3 juin, par Kevin McDowell

    I am trying to record a walkthrough of a 3D space contained within a Chrome browser session. The goal is to create deterministic output. If I run this command from a VS Code terminal, it records 30 seconds of video from the window that's about 6MB:

    ffmpeg -f gdigrab -framerate 30 -i "title=My3D - Google Chrome" -t 30 "My3D - Google Chrome_screenRecording_v0.mp4"

    However, if I call it from Python like so:

    subprocess.run("ffmpeg -f gdigrab -framerate 30 -i \"title=My3D - Google Chrome\" -t 15 \"My3D - Google Chrome_screenRecording_v0.mp4\"")

    The output video is 30 seconds, but while I can see the mouse moving on the screen, the image is all black and the filesize is only 94KB.

    This is on a Windows 11 machine with GPU acceleration disabled in the OS as well as in Chrome. I've also tried it with other web pages and those are also recorded black. Any ideas what is causing this or how to record the screen using Python?

    I've got other alternatives working (using Selenium or PyGet to capture screenshots and then using the VideoWriter class from OpenCV to write them to a video file), but that has a limitation of only about 10 FPS and you can't control the recording time like you can with FFMPEG. If you screen capture for 30 seconds, the actual output may only be 12-18 seconds.

  • How to add a fake microphone to android emulator running on linux headless

    2 juin, par Red

    Trying to add a microphone to the android emulator running on Linux headless. Host as no microphone so I need to create fake one and simulate playing some random music for my android test.

    In emulator command there is a option to use the host audio as input, by passing -allow-host-audio but it is not working on the phone.

    How to create virtual microphone Start the pusleaudio

    pulseaudio -D --exit-idel-time=-1

    Create the fake mic

    pactl load-module module-null-sink sink_name=FakeSink

    pactl load-module module-remap-source master=FakeSink.monitor source_name=FakeMic

    And set to default

    pactl sets default FakeSink.monitor

    Microphone test

    $ffmpeg -f pulse -i default out.wav


$ sox out.wav -n stat

  • Attempting to parse an m3u8 file in FFmpeg with mismatched extensions and formats

    2 juin, par Daniel Melo

    As I attempt to parse an m3u8 file thats being downloaded over the air, it utilizes "html" as an extension to represent the ts video slices. Even with the command being written as follows:

    ffmpeg -allowed_extensions ALL -i https://.../master.m3u8 -codec copy ./out.mkv

    It still produces the following error:

    detected format mpegts extension none mismatches allowed extensions in url (...)/page-0.html

    Could there be a way to ignore this format and extension mismatch?

find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do

EXTRACT_ARCHS=$(lipo -info "$FRAMEWORK_EXECUTABLE_PATH" | rev | cut -d ':' -f1 | rev)
ARCHS_TO_REMOVE=""

for ARCH in $EXTRACT_ARCHS; do
    if [ "$ARCH" != "arm64" ]; then
        ARCHS_TO_REMOVE="$ARCHS_TO_REMOVE -remove $ARCH"
    fi
done

if [ ! -z "$ARCHS_TO_REMOVE" ]; then
    lipo $ARCHS_TO_REMOVE "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH" || exit 1
fi
done

    I have already tried some suggestion from online but nothing worked.
