This provides basic operations for the video switcher, "LiveWedge".

(See http://livewedge.cerevo.com/en/ about LiveWedge.)

This library is still alpha version. Compatiblity may break in future update.

• Screen transfer: Cut, Mix, Dip, Wipe
• Sub screen control: PinP, Chroma-key
• Start and stop recording and broadcasting
• Upload a still picture and use it as ch.4 input source
• Find LiveWedge within the same network

Getting status from LiveWedge is still under construction. func (vsw Vsw) Request* are not yet fully documented.

Common library for manupulating LiveWedge by network.

Sample program to make video transition automatically. See src/autotrans/00Readme.txt

Very simple program just to repeat cut and mix.

Very simple program just to repeat wipe all pattern.

Very simple program of Picture in Picture.

Very simple program of chroma key.

Very simple program just to send recording start/stop command with web UI.

A sample program for getting status via UDP.

A sample program for finding a LiveWedge within the same network.

0. Install go language. Tested in linux/amd64. Go version 1.4 and 1.5. I hope Mac/Windows works, too.

1. Execute ./make.sh at the top directory.

https://godoc.org/github.com/cerevo/LiveWedge_API/src/libvsw

At first, create vsw instance.

ip_address := "192.168.21.5" //ip address of LiveWedge
vsw, err := libvsw.NewVsw(ip_address)
if err != nil {
	fmt.Fprintf(os.Stderr, "Failed to open LiveWedge: %s\n", err)
	os.Exit(1)
}
defer vsw.Close()

Then, invoke method of vsw. For example, cut every 3 seconds.

i := 0
for {
	vsw.Cut(i + 1)  // src is {1..4}
	i = (i + 1) % 4
	time.Sleep(3 * time.Second)
}

See src/sample_trans/sample_trans.go for complete example.
