connection closed event

[wasawi]

Hi,

I'm running tests using the example_server_binary_video with videos of many different formats. I usually loose the connection with the client. I would like to know how to start looking for solutions/debugging. I'm quite new at websockets programing so sorry for my very naive questions.

Is it possible to automatically reconnect after a close event? Is the close event due to a lack of time in the javascript side to process the event? if so could that be solved? Has anybody done some tests with heavy videos or high framerates?

I will be looking at this addon for a while so any hints will be very appreciated!

Best, J

BTW is it better to discuss this at the of forum?

My specs: Visual Studio 2015 (Win 7 Pro) Firefox 43.0.4 libwebsockets-1.3-chrome37-firefox30

Hello!

Totally not a naive question–video with websockets is still a little crazy. It could be the size of the messages, or the speed; I've worked a lot lately to make ofxLibwebsockets work with huge messages, but it's perfectly possible there's an error on my side!

A few questions for you:

• Can you post what the library is logging out when the connection closes?
• Can you try the "blob" example? It'll be much, much easier for you on the javascript side

P.S. To try an autoconnect scheme, check out ofxSpacebrew, which uses ofxLibwebsockets, for an example:

• Catch the "onClose" event
  • Use the addListener on libwebsockets to catch event (all examples have this!) https://github.com/Spacebrew/ofxSpacebrew/blob/master/src/ofxSpacebrew.cpp#L284
  • Catch onClose: https://github.com/Spacebrew/ofxSpacebrew/blob/master/src/ofxSpacebrew.cpp#L551
• On update(), check if connection is closed, how long it's been since you last tried to reconnect, and give it a shot if it's not been too long: https://github.com/Spacebrew/ofxSpacebrew/blob/master/src/ofxSpacebrew.cpp#L304

Thank you so much for the great reply! I'll have a look at it now.
