    I have generated my key and certificate using OpenSSL :

    $ openssl req -newkey rsa:2048 -nodes -keyout domain.key -x509 -days 365 -out domain.crt
    
$ sudo cp test.crt /usr/local/share/ca-certificates/
    
$ sudo update-ca-certificates

    Can someone drop me a hint or a pointer ?

  • Artifact while streaming multicast with ffmpeg

    17 août 2018, par Nicosmik

    Locally, from my windows machine with ffmpeg 3.3.2 from Zeranoe

    Server side

    Launch udp multicast streaming.

     ffmpeg -re -i video.ts -an -f mpegts -c copy udp://224.1.1.1:5000

    Client side

    Playing with ffplay is correct, no artifacts displayed

    ffplay udp://224.1.1.1:5000

    Playing after decoding cause artifacts

    ffmpeg -i udp://224.1.1.1:5000 -pix_fmt gray -f avi - | ffplay -

    or

    ffmpeg -f mpegts -i udp://224.1.1.1:5000 -pix_fmt gray -c:v rawvideo -f avi out.avi

    Does someone has an explanation ?
