Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;

FFMPEG Streaming webcam on Windows 10 to RTP
23 juillet 2019, par gdogg371I am still trying to figure out exactly what I am doing with ffmpeg and dshow. However I am trying to stream a 4k capture device I have, so that I can use this as an IPTV server downstream.
So far I have :
ffmpeg -rtbufsize 2100M -y -loglevel warning -f dshow -i video="Video (00 Pro Capture HDMI 4K+)" -s 3840x2160 -vcodec v410 -f rtp rtp://192.168.1.31:8554
...however this is throwing up the following errors :
C:\Program Files\VideoLAN\VLC>ffmpeg -rtbufsize 2100M -y -loglevel warning -f dshow -i video="Video (00 Pro Capture HDMI 4K+)" -s 3840x2160 -vcodec libx265 -f rtp rtp://192.168.1.31:8554

Can anyone suggest a remedy ?
Thanks
