  • FFMpeg Error initializing filter 'drawtext' on Android project

    14 janvier 2019, par user3884677

    I try to draw a text on a video using FFMpeg but I have the error :

    My problem is that I can not use the option ’drawtext’. When I don’t use the option ’drawtext’ it’s work. I do not know which syntax I should use.
    I tried a lot of possibilities without success.
    I use this library : http://writingminds.github.io/ffmpeg-android-java/

    Can you help me ?

  • Opencv is working for my project on my laptop but stop working on raspberry pi

    10 mars 2021, par Clovis Tiwange

    Good morning all ! I despair (This is my first post).
I am trying to set up a human detection system using the openvino toolkit. I am using an example project provided by openvino at the following openvino multi target tracking. I first tested them on my computer (ubuntu) and it worked. I have now tried to run the project on raspberry pi but it gets stuck at opencv level. I followed the following tutorial Install openvino on rasbian for setting up openvino.
While debugging, I realized that the problem was with cv2.videocapure (link). Apparently there is a problem with the backend ffmepg but also GStreamer.

    


    I run the following command

    


    python3 multi_camera_multi_target_tracking.py     -i http://192.168.137.160:4747/video    --m_detector model/intel/person-detection-retail-0013/FP32/person-detection-retail-0013.xml     --m_reid model/intel/person-reidentification-retail-0031/FP32/person-reidentification-retail-0031.xml     --config config.py -l /opt/intel/openvino/deployment_tools/inference_engine/lib/intel64/libcpu_extension_avx2.so


    


    And i have the following results

  • pyInstaller : Pack binary executable inside project's executable to run

    18 décembre 2023, par zur

    TLDR ;

    


    I would like to pack the ffmpeg executable inside my own executable. Currently I am getting

    


    FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'
Skipping ./testFile202312061352.mp4 due to FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'


    


    Details :

    


    I am creating executable file using following command :

    


    pyinstaller cli.py \&#xA;  --onefile \&#xA;  --add-binary /Users/<machineuser>/anaconda3/envs/my_env/bin/ffmpeg:bin&#xA;</machineuser>

    &#xA;

    The code that uses ffmpeg is not authored by me. And I would like to keep that part the same.

    &#xA;

    When I run from command line while conda environment is active I can successfully run it as python (or perhaps anaconda) knows where the binaries are. I have a pretty empty cli.py. That seems to be the entry point and I hope if it is possible I can set the bin directory's path there ...

    &#xA;

    I am able to successfully run the application like following :

    &#xA;

    (my_env) machineUser folder % "dist/cli_mac_001202312051431" ./testFile202312061352.mp4&#xA;

    &#xA;

    I would like to run like following :

    &#xA;

    (base) machineUser folder % "dist/cli_mac_001202312051431" ./testFile202312061352.mp4&#xA;

    &#xA;

    I would like to keep the world out side my executable's tmp folder the same. I would not want to change something that will be "left behind" after the exec is terminated.

    &#xA;

    Question :

    &#xA;

    Can some one please mention how to modify the pyinstaller command or what to change in cli.py to achieve it successfully ?

    &#xA;
