Hmm... It's difficult to find the cause of this problem from the log you pasted. I need to check what bytes are sent from rtmp client.

Could you run the proxy and paste the output?

$ go run _example/server/main.go -addr :1936

After that

$ go run _example/proxy/main.go -laddr :1935 -raddr :1936
...

c-bata avatar Feb 02 '18 13:02 c-bata

first example:

$ go run _example/server/main.go -addr :1936

output:

Thank you for trying this. But sorry, could you paste the output of proxy? Maybe it's really long, so if you can't paste all output in this comment area, please paste the last two blocks of byte streams.

c-bata avatar Feb 06 '18 08:02 c-bata

in process right now ;)

moneyzmey avatar Feb 06 '18 08:02 moneyzmey

About proxy, i got connection refused.

output:

moneyzmey avatar Feb 06 '18 08:02 moneyzmey

Hmm....? Did you run rtmp server at :1936 port?

c-bata avatar Feb 06 '18 08:02 c-bata

Yes, it my mistake, forgot to do it last two blocks:

Same problem here...

@saturday06 tells me the cause of this problem might be below:

  1. When FMT field in chunk basic header is 2 or 3, we need to re-use chunk data from the previous received one.
  2. Sometimes the length of chunk data doesn't match that client sends.

I don't know how can I fix the second one. But anyway, I'll investigate this problem again. Thanks
