Thanks. Could you provide a swf or html that causes this error? Some users have reported the same kind of error, but I have been failed to reproduce the error.

[nvcken]

I don't use swf or html, I implement iOS feed camera streaming via RTMP to node server.
This is what I use for iOS https://github.com/jgh-/VideoCore to do rtmp feed

[nvcken]

I tried use pure js instead of coffee, then I got this error

I rebuild and run twice again Error: Unknown AMF0 data type: 108 always occurs -> maybe this is main error, we can skip Error: Supplied key is too small

[iizukanao]

Thanks! I've reproduced the error and now I'm investigating the problem.

素晴らしい

😄 I've fixed AMF0 parser and it should work with VideoCore library. However, VideoCore has a bug too, and it sends invalid AMF0 data (created a pull request). So, the server still prints error message, but the streaming will work. Please give it a try.

[nvcken]

Now Error: Unknown AMF0 data type: 108 is gone, but many times get Error: Supplied key is too small error then server crash.
When get that error I need to start server again, then restart iOS app too, then streaming works again.
p/s: I also updated code from your PR on VideoCore

[iizukanao]

OK, I've just fixed that problem too. Please pull the latest code from master.

[nvcken]

Wow, tried it. Cool.
I am curiously how did you reproduced with VideoCore and then found out where problem so fast.
Did you reproduce by the way integrate VideoCore to a blank Xcode project (add some code capture camera) then build to device ?

[iizukanao]

Thanks 😃
I just used a sample project included in VideoCore (SampleBroadcaster-Swift) and ran it on iOS device. Your assistance greatly helped, too!
