AlohaRTC
Real-time communication with embedded cameras, natively within the browser
Building
First, download dependencies:
make get
To cross-compile for a Raspberry Pi Model 3B/3B+ (armv7-based architecture):
make
To cross-compile for a Raspberry Pi Zero (armv6-based architecture):
GOARM=6 make
To build for production:
GOFLAGS="-tags=production" make
Quickstart
Build code as above, then transfer alohacam to Raspberry Pi and run. Open
http://<target>:8000 in browser. This should start a live video stream from
Raspberry Pi.
Notes
Ensure camera is enabled on Raspberry Pi and that v4l2 module is loaded.
Modify /etc/modules as follows:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
bcm2835-v4l2
...
Modify /boot/config.txt as follows:
boot/config.txt
...
start_x=1
gpu_mem=128

Types ¶
type Config ¶
type Config struct {
LocalAudio media.AudioSource
LocalVideo media.VideoSource
}
type PeerConnection ¶
type PeerConnection struct {
// RTP payload type (negotiated via SDP)
DynamicType uint8
// Callback when a local ICE candidate is available.
OnIceCandidate func(*ice.Candidate)
// contains filtered or unexported fields
}
func Must ¶
func Must(pc *PeerConnection, err error) *PeerConnection
Must is a helper that wraps a call to a function returning (*PeerConnection, error) and panics if the error is non-nil. It is intended for use in variable initializations such as
var pc = alohartc.Must(alohartc.NewPeerConnection(config))
func NewPeerConnection ¶
func NewPeerConnection(config Config) (*PeerConnection, error)
NewPeerConnection creates a new peer connection object
func NewPeerConnectionWithContext ¶
func NewPeerConnectionWithContext(ctx context.Context, config Config) (*PeerConnection, error)
NewPeerConnectionWithContext creates a new peer connection object
func (*PeerConnection) AddIceCandidate ¶
func (pc *PeerConnection) AddIceCandidate(c *ice.Candidate)
AddIceCandidate adds a remote ICE candidate.
func (*PeerConnection) SetRemoteDescription ¶
func (pc *PeerConnection) SetRemoteDescription(sdpOffer string) (sdpAnswer string, err error)
Set remote SDP offer. Return SDP answer.
func (*PeerConnection) Stream ¶
func (pc *PeerConnection) Stream() error
Stream establishes a connection to the remote peer, and streams media to/from the configured tracks. Blocks until an error occurs, or until the PeerConnection is closed.
