Thanks, feel free to file a bug if/when you'd like to get some feedback about
this implementation. We are looking forward a replacement for RTMP library
which isn't the best fit, specially due to threading and error handling.

Thanks for pointing this out. I think we can learn from this. Notice that it
initially ad a socket close(), and then removes it (using only shutdown()) to
unblock. Could be a shorter term solution until a replacement is ready and
merged.

I think that meanwhile Pexip has moved and have their own rtmp library and
their own element too. I think creating a bug for Andreas replacement would be
a good way to discuss this.
