This example will connect to the Bebop and stream it's video to a webpage
|
|
via ffserver. This requires you to have both ffmpeg and ffserver installed
|
|
on your computer.
|
|
|
|
In order to run this example you will first need to start ffserver with:
|
|
$ ffserver -f ff.conf
|
|
|
|
then in a separate terminal run this program:
|
|
$ go run video.go
|
|
|
|
You will then be able to view the video feed by navigatin to
|
|
http://localhost:8090/bebop.mjpeg in a web browser. *NOTE* firefox works
|
|
best for viewing the video feed.
