• 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 ?

  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 ?
