Bir web sitesinde görüntülemek istediğim bir Unifi UVC kameram var. Birkaç haftadır bunu yapmak için ffmpeg kullanıyorum. Ama hayır artık işe yaramayacak. Akışı doğrudan kameradan unifyi Video ile izleyebilirim. Kameranın IP'sinde. Rtsp akışını vlc ile açabilirim, ancak birkaç saniye sonra kopar.
Benim ffserver.conf:
Port 8090
# bind to all IPs aliased or not
BindAddress 0.0.0.0
# max number of simultaneous clients
MaxClients 1000
# max bandwidth per-client (kb/s)
MaxBandwidth 100000
# Suppress that if you want to launch ffserver as a daemon.
