@ -57,11 +57,12 @@ Usage
-Q length: Number of frame queue (default 10)
-O output: Copy captured frame to a file or a V4L2 device
RTSP options :
-u url : unicast url (default unicast)
-m url : multicast url (default multicast)
-M addr : multicast group (default is a random address)
-P port : RTSP port (default 8554)
-H port : RTSP over HTTP port (default 0)
-T port : RTSP over HTTP port (default 0)
-u url : unicast url (default unicast)
-m url : multicast url (default multicast)
-M addr : multicast group (default is a random address)
-c : don't repeat config (default repeat config before IDR frame)
V4L2 options :
-r : V4L2 capture using read interface (default use memory mapped buffers)
-s : V4L2 capture using live555 mainloop (default use a separated reading thread)
