  • Streaming x264 with packet loss

    6 octobre 2014, par user2629511

    I write the program where I use x264 as the coder.
    I use the following parameters :

    av_opt_set (codecContextH264[numberCoder]-> priv_data, "profile", "baseline", 0);
    
av_opt_set (codecContextH264[numberCoder]-> priv_data, "preset", "ultrafast", 0);
    
av_opt_set (codecContextH264[numberCoder]-> priv_data, "tune", "zerolatency", 0);
    
codecContextH264[numberCoder]-> bit_rate =bitrate;
    
codecContextH264[numberCoder]-> bit_rate_tolerance=bitrate-5000;
    
codecContextH264[numberCoder]-> width = w;
    
codecContextH264[numberCoder]-> height = h;
    
codecContextH264[numberCoder]-> time_base.den = fps;
    
codecContextH264[numberCoder]-> time_base.num = 1;
    
codecContextH264[numberCoder]-> pix_fmt = PIX_FMT_YUV420P;
    
codecContextH264[numberCoder]-> gop_size = fps*3;
    
codecContextH264[numberCoder]-> keyint_min = fps*3;
    
codecContextH264[numberCoder]-> max_b_frames = 0; 
    
codecContextH264[numberCoder]-> slices = (int) (w*h)/1500+1;

    I use only I and P frames.
    What x264 settings I shall use that could lose P frames ?
    Perhaps x264 has no such opportunity ?!
    I read that if to use a "base" profile, it is possible to lose P frames...
    Help please.

  • Laravel Queue Timeout

    25 juin 2021, par Teldar

    I'm running Laravel queue with that command :

    



    /usr/bin/php7.2 artisan queue:listen --timeout=0


    



    But the process keeps stopping at 300 seconds with that error :

    



    Symfony\\Component\\Process\\Exception\\ProcessTimedOutException(code: 0): The process [...] exceeded the timeout of 300 seconds


    



    I've also tried to set timeout in job's class :

    



    public $timeout = 5000;


    



    Anyone know what to do ? This process is for video encoding so a bit long running.

    



    Thx !

    


  • How to convert ffmpeg raw stdout to video

    20 juin 2018, par Данил Вагапов

    I use ffmpeg to capture video from my webcam and stream it via netcat.

    ffmpeg -f v4l2 -r 25 -s 640x480 -i /dev/video0 -f avi pipe:1 | nc -l -p 5000

    I wanna display the stream on my surface view, but I still don’t know how to do it.
    I use socket to get the data from netcat.
    What’s the simpliest way to convert and display this data ?
