Webcam Streamer

Streams video from a camera (or test file) to a browser peer via WebRTC. Encodes to H.264 and sends through the PacketStream pipeline.

Pipeline: MediaCapture → VideoPacketEncoder → WebRtcTrackSender → [browser]

Build

Built automatically when -DBUILD_SAMPLES=ON is passed to CMake and the webrtc module prerequisites are available.

Requirements

• Camera (or set USE_CAMERA to 0 for test file)
• FFmpeg with libx264 encoder
• Running Symple server
• A browser client that can place a Symple-backed WebRTC call

Usage

./webcam-streamer -host 127.0.0.1 -port 4500 -user streamer -name "Webcam"

Connect from a browser using symple-player's CallManager. The streamer auto-accepts incoming calls and begins sending H.264 video.

Set USE_CAMERA to 1 in the source to stream from a camera instead of the test file.

Operational Notes

• The sample joins the public room after coming online.
• It builds the media pipeline once and starts capture only when PeerSession reaches Active.
• If you are debugging signalling, check that the browser can see the streamer's presence before you touch the media path.
• If you are debugging media, switch to the test file first so camera negotiation is not part of the problem.
