मेरे पास एक यूनिफी यूवीसी कैम है जिसे मैं एक वेबसाइट पर देखना चाहता हूं। मैं कुछ हफ्तों के लिए ऐसा करने के लिए ffmpeg चला रहा हूं। लेकिन अब यह काम नहीं करेगा। मैं यूनिफाई वीडियो के साथ कैमरे से धारा को प्रत्यक्ष देख सकता हूं। कैम के आईपी पर। मैं vlc के साथ rtsp स्ट्रीम खोल सकता हूं, लेकिन यह कुछ सेकंड के बाद टूट जाता है।
मेरा 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.
