  • ffmpeg remote url not working in lambda function

    9 September 2024, by Komal

    I have created lambda function to trim video.

    


    I run this command:

    


    /opt/bin/ffmpeg -protocol_whitelist file,http,https,tcp,tls -i 'https://source-bucket.s3.amazonaws.com/1.mp4' -ss 5 -t 10 -loglevel 48 -y -avoid_negative_ts 1 -acodec copy /tmp/output.mp4


    


    It gives following output:

    So, its not going beyond this: 'Opening 'https://source-bucket.s3.amazonaws.com/1.mp4'; for reading\n'

    


    And after this, it immediately gets out. Need suggestions, where its going wrong. Same command working fine on local computer.

    


    I tried cloudfront and signed url as well, as mentioned in this post: How to read remote video on Amazon S3 using ffmpeg. But it doesnt work with url. Only working when downloaded into tmp folder.

    


    Following is the final log, which you can see is no timeout. It actually finish function execution within 2-3 seconds. I have timeout set for 15 mins to the function which is maximum:

  • avformat/hls: Be more picky on extensions

    16 January, by Michael Niedermayer
    avformat/hls: Be more picky on extensions

    This blocks disallowed extensions from probing
    
It also requires all available segments to have matching extensions to the format
    
mpegts is treated independent of the extension
    

    It is recommended to set the whitelists correctly
    
instead of depending on extensions, but this should help a bit,
    
and this is easier to backport
    

    Fixes: CVE-2023-6602 II. HLS Force TTY Demuxer
    
Fixes: CVE-2023-6602 IV. HLS XBIN Demuxer DoS Amplification
    

    The other parts of CVE-2023-6602 have been fixed by prior commits

  • Reading images from AXIS ip camera using OpenCV

    14 June 2016, by batuman

    I am trying to access AXIS IP camera from my program using OpenCV.
    My OpenCV version is 3.1. I follow this tutorial link.

    I have all libraries installed.
    My following program can load mp4 video successfully. That means ffmpeg and necessary libraries are working fine.

    #include <iostream>
    
#include <opencv2></opencv2>opencv.hpp>
    

    
using namespace std;
    
int main() {
    
    cv::VideoCapture vcap("test.mp4");
    
    cv::Mat image;
    
//    const string address = "rtsp://root:pass@192.168.0.90/axis-media/media.amp?camera=1";
    
//    if(!vcap.open(address)){
    
//      std::cout &lt;&lt; "Error opening video stream or file " &lt;&lt; std::endl;
    
//      return -1;
    
//    }
    
    for(;;){
    
        if(!vcap.read(image)){
    
            std::cout &lt;&lt; "No frame" &lt;&lt; std::endl;
    
            cv::waitKey(0);
    
        }
    
        cv::imshow("Display", image);
    
        cv::waitKey(1);
    
    }
    
    return 0;
    
}
    
</iostream>

    When I tried to access the IP Camera as follow

    cv::VideoCapture vcap("rtsp://root:pass@192.168.0.90/axis-media/media.amp?camera=1");

    I have the following error

    GStreamer Plugin: Embedded video playback halted; module source reported: Could 
    
not open resource for reading and writing.
    
OpenCV Error: Unspecified error (GStreamer: unable to start pipeline

    User is root and password is pass and ip 192.168.0.90 are all defaults.

    My if config gave me

    What could be the problem for this access to the camera?

    Thanks
