  • Bad behavior live streaming from opencv to ffserver (ffmpeg)

    9 octobre 2015, par jlarghi

    I’m trying to do live streaming of the traffic videos.

    I have this fragment of C++ code :

    Mat frame, output;
    
Size sizeOutput(640,360);
    
cvtColor(frame, output, CV_RGB2GRAY);
    
resize(output, output, sizeOutput);
    
cout << output.data;

    In the other hand I run :

    ./opencvvehicletrack | ffmpeg -f rawvideo -pix_fmt gray -s 640x360 -i - -an  http://localhost:8090/feed1.ffm:

    Where opencvvehicletrack print on the stdout.

    And I got the next result : https://youtu.be/HqpAv_oi3u4

    I can’t fix the "continous displacement to the right"

    Can anyone help me ? Thanks a lot.

  • How can i stop ffmpeg buffer from streaming ?

    23 juin 2020, par sniper

    I try to obtain a screenshoot for live streaming when websockets announce he need a screenshoot.

    


    At this moment I use this command for a subprocess on python :

    


    command = 'ffmpeg -ss 00:00:01 -i '+str(urllive)+' -vframes 1 -q:v 2 /var/www/html/ai/dist/img/'+str(canlive)+'.png -y'

    


    the script is working very well but this command is a for iteration, and execute the command for 7-12 times in less than 1 second.
The problem is when ffmpeg take the screenshoot start the streaming and take the buffer for this stream.
The buffer stream have around 7MB * 10(iteration) mean 70 MB, and load the network traffic with 70MB*8 = 560Mbps on that second.
How can i disable or reduce the buffer on ffmpeg client ?
    
I tried with bufsize 1M, -fflags nobuffer args but no success.

  • How to detect transfer rate of a stream group in ffmpeg ?

    17 décembre 2014, par frankish

    I am streaming only 1 single audio content of a stream group. I write it as "stream group", because sometimes the streaming url may be a url of a television broadcast which is composed of 1 video and 1 or more audio streams.

    Currently I loop and select one of the audio streams and play it. I also track the data transfer rate so I show a data-traffic monitoring screen like a quota management system. When I discard video and play only audio, data transfer calculation is no longer correct.

    Basically, I want to track how many kbytes ffmpeg downloads per second (directly related to bitrate or not). Where should I look ?
