  • Python OpenCV FFMPEG RTSP Stream timeout triggered after 30015.187000 ms

    24 février 2024, par BatCoder

    I am trying to read several RTSP streams using opencv cv2.VideoCapture(URL). It has FFMPEG backend. Sometimes for few streams it is throwing timeout warning after 30 seconds.

    


    [ WARN:0@123.394] global cap_ffmpeg_impl.hpp:453 _opencv_ffmpeg_interrupt_callback Stream timeout triggered after 30015.187000 ms


    


    I tried setting up the timeout flag.

    


    import os
os.environ["OPENCV_FFMPEG_CAPTURE_OPTIONS"] = "timeout;5000" # 5 seconds 
cv2.VideoCapture("rtsp://URL", cv2.CAP_FFMPEG)


    


    Ref : How to terminate cv2.VideoCapture(rtsp_url) call if execution stalls due to RTSP camera issues ?

    


    But still, it is waiting for 30 seconds before raising the warning.

    


    OpenCV version : 4.4.0.x
Python version : 3.9.x

    


    Can we decrease the wait time from 30 seconds to a lower number ?

  • FFPMEG command to record screen works only from cmd on windows but not from my Java class

    21 mars 2024, par Youssef Hammouma

    i have a JUNIT test that uses a Java class called ScreenRecordingWatcher where i specified my ffpmeg command to record the computer when my test fails.

    


    But unfortunately, my command only works from my cmd and not from my class, On both sides it generates successfully my file, but when it is generated from my Java class, the file is not readable from my windows player (0xc10100be error).

    


    Here is the command i am using :

    


    C:\outils\ffmpeg-master-latest-win64-gpl\bin\ffmpeg.exe -f gdigrab -framerate 30 -i desktop -c:v h264_nvenc -qp 0 C:\outils\video\output.mkv


    


    Here is the same command from my class :

    


    public class ScreenRecordingWatcher extends TestWatcher {

private static final String FFMPEG_PATH = "C:\\outils\\ffmpeg-master-latest-win64-gpl\\bin\\ffmpeg.exe";
private static final String OUTPUT_FILE = "C:\\outils\\video\\fichier.mkv";
private boolean testFailed = false;

@Override
protected void failed(Throwable e, Description description) {

    super.failed(e, description);
    testFailed = true;
}

@Override
protected void finished(Description description) {
    super.finished(description);
    if (testFailed) {
        startRecording();

        try {
            Thread.sleep(5000);

        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }
        stopRecording();
    }
}

private void startRecording() {
    String[] command = { FFMPEG_PATH, "-f", "gdigrab", "-framerate", "30", "-i", "desktop", "-c:v", "h264_nvenc", "-qp", "0", OUTPUT_FILE };

    System.out.println(Arrays.toString(command));
    ProcessBuilder builder = new ProcessBuilder(command);
    try {
        builder.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

private void stopRecording() {
    String[] command = { "tskill", "ffmpeg" };
    ProcessBuilder builder = new ProcessBuilder(command);
    try {
        builder.start();
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}


    


    }

    


    Does someone have an idea of why it executes well from my cmd but not from my class ?

    


    Thank you in advance
