IDeviceStreamProbe

Interface in Oadm.Sdk.Devices · Oadm.Sdk.dll

An open measuring stream; dispose to end it (RTSP TEARDOWN).

public interface IDeviceStreamProbe : IAsyncDisposable

Extends IAsyncDisposable

Properties

Codec

string Codec { get; }

The codec the camera streams (“h265” or “h264”).

Completion

Task Completion { get; }

Completes when the stream ends: normally after IAsyncDisposable.DisposeAsync, faulted with DeviceStreamException when the device closes or the connection breaks.

Fps

int Fps { get; }

The asked frame rate (frames per second the camera should send).

Height

int Height { get; }

The streamed height.

StartedUtc

DateTimeOffset StartedUtc { get; }

When the first video packet arrived.

Transport

StreamProbeTransport Transport { get; }

UDP or TCP, as negotiated.

UdpBlocked

bool UdpBlocked { get; }

Default implementation

True when the probe asked for UDP, the camera agreed, but no video arrived over UDP in the first seconds (a firewall or NAT on the way drops it), so it streams over TCP instead. False otherwise, also when the camera refused UDP or the device is at a site. SDK 0.6.0.

Width

int Width { get; }

The streamed width.

Methods

Read

StreamProbeCounters Read()

The counters since the start; cheap, thread-safe, call it once per second and take the difference.
