Input

Black Screen Check

Sometimes your camera turned off or lost its connection but its FFmpeg process still insists on running. This may mislead the watchdog mechanism and prevent it from taking immediate action. You can enable the black screen checker to avoid that kind of situation. But remember, Black Screen Checker runs a separate FFprobe process every ten minutes and running a process can be costly. It is not recommended to be enabled on a Raspberry PI or other low-powered devices.

RTSP Transport

RTSP default protocol is TCP. But you can choose UDP or HTTP (useful for passing proxies) depending on your camera address.

Analysis Duration

The size (in bytes) of the data to analyze to get stream information. A higher value will enable detecting more information in case it is dispersed into the stream, but will increase latency. Must be an integer not lesser than 32.It is 5000000 by default.

Probe Size

Specify how many microseconds are analyzed to probe the input. A higher value will enable detecting more accurate information, but will increase latency. It defaults to 5,000,000 microseconds = 5 seconds.

FPS

The desired output frame rate. The default is 25. Leave it 0 if you don't want to specify it.

Use Hardware Accelerator

This option enables HW-assisted decoding to reduce CPU usage and latency. You can achieve 500ms stream delay if the websocket stream type or low latency FLV player is selected.
