Hi @juexun

Thanks for checking out Pion! You can generate it by running curl localhost:8080/sdp -d "Browser SDP" then the broadcast binary will print it to stdout.

broadcast has more documentation around it. Please re-open or reach out on Slack if you have more questions.

thanks

@Sean-Der I also fact this issue.
And I try follow your command above but it still does not work.

@RathanakSreang are you running the curl command on the same computer you ran broadcast/main.go?

Thanks

@Sean-Der Yes, I do. But the result i got is just HTML code instead.

Something else is listening on :8080 then. Probably examples.go ? I would use the JSFiddle link in the broadcast README, and make sure nothing else is running.

I've just tried this on the lastest trunk branch - I also just get the raw HTML
using: go run examples.go --address localhost:8080
then curl localhost:8080/sdp -d "Browser SDP"

OK so I was having a mental block about where $BROWSER_SDP comes from. So will explain here for the benefit of others.

Say you want to run the reflect example, then open the reflect jsfiddle page linked from here. Click on the text [A] from the box called "Browser base64 Session Description". Then go back into the linux bash shell / osx terminal where you have installed the webrtc examples and done a export GO111MODULE=on go get github.com/pion/webrtc/v3/examples/reflect

Now in the examples/reflect directory, enter
echo $BROWSER_SDP | reflect
where $BROWSER_SDP is the text [A] we copied from the jsfiddle "Browser base64 Session Description" box.

The terminal will then print another base64 string which we past into the other box in the jsfiddle page.
Should work now...

curl localhost:8080/sdp -d "Browser SDP"

Hi, curl localhost:8080/sdp -d "Browser SDP". not working for me, it shows:
curl: (7) Failed to connect to localhost port 8080: Connection refused

Thank you

curl localhost:8080/sdp -d "Browser SDP"

Gives done in stdout and panic in application:

panic: illegal base64 data at input byte 7

goroutine 1 [running]:
join/signal.Decode(0xc0001b0580, 0xb, 0x1416ac0, 0xc0001c4260)
/Users/alex/GoProjects/join/signal/signal.go:63 +0xd9
main.main()
/Users/alex/GoProjects/join/main.go:22 +0xc5

Because Decode func expects valid base64 string with JSON inside.

Hey @AlexanderMatveev you don't want to send "Browser SDP" but the base64 value in the textarea

If you get a chance would you mind updating the docs to be more descriptive? This has confused multiple people, not sure of a better way to work it though.

@Sean-Der Thanks for response, I got it from code. But I didn't found any information about where must I get this base64-string.
