Send Video

Use VideoSender when a pipeline should send video to an external receiver. VideoSender is a real NodeGroup, so it is added through Session::add(...).

The current wire format is H.264 over RTP/UDP. The default UDP port rule is video_port_base + channel, with video_port_base = 9000. If the receiver runs behind container port remapping, pass the mapped host and a matching video_port_base from the app.

Raw Frames​

Use the raw path when the pipeline input to VideoSender is raw video frames. NEAT will convert, encode, packetize, and send:

VideoConvert -> H264EncodeSima -> H264Parse -> H264Packetize -> UdpOutput
simaai::neat::Session session;
const int channel = 0;

auto opt = simaai::neat::nodes::groups::VideoSenderOptions::H264RtpUdpFromRaw(
    width, height, fps);
opt.host = "127.0.0.1";
opt.channel = channel;
opt.video_port_base = 9000;
opt.encoder.bitrate_kbps = 2500;

session.add(simaai::neat::nodes::groups::VideoSender(opt));

Python:

channel = 0

opt = pyneat.VideoSenderOptions.h264_rtp_udp_from_raw(
    width=1920,
    height=1080,
    fps=30,
)
opt.host = "127.0.0.1"
opt.channel = channel
opt.video_port_base = 9000
opt.encoder.bitrate_kbps = 2500

session.add(pyneat.groups.video_sender(opt))

Encoded H.264​

Use the encoded path when the upstream pipeline already produces H.264. NEAT will parse, packetize, and send without re-encoding:

H264Parse -> H264Packetize -> UdpOutput
const int channel = 0;

auto opt = simaai::neat::nodes::groups::VideoSenderOptions::H264RtpUdpFromEncoded();
opt.host = "127.0.0.1";
opt.channel = channel;
opt.video_port_base = 9000;

session.add(simaai::neat::nodes::groups::VideoSender(opt));

Python:

channel = 0

opt = pyneat.VideoSenderOptions.h264_rtp_udp_from_encoded()
opt.host = "127.0.0.1"
opt.channel = channel
opt.video_port_base = 9000

session.add(pyneat.groups.video_sender(opt))
